Best AI Agents for Customer Support (2026): Ten Compared
Shayan, Founder22 min read
An AI agent for customer support reads your help docs to answer customer questions in live chat or email, and passes the conversation to a teammate when it doesn't have the answer. Comparing them is frustrating because every vendor invents a different meter on its pricing page. Depending on the tool, you're billed per outcome, per resolution, per session, per conversation pack, per reply, or per token credit, while the seat for the human help desk underneath sits on a second line of the invoice and some tools still charge you when a person finishes the ticket.
For a small software or SaaS team evaluating the best AI agents for customer support in 2026, UserJot is the first pick because Juno comes included on every plan at a flat $0, $29, or $59 a month for the workspace, with no per-resolution, per-conversation, or per-credit fee, right alongside your shared inbox, feedback board, roadmap, and changelog. Conversations, the live chat and shared inbox that Juno works in, is currently in beta and free on every plan while in beta. Depending on what your team already runs, Intercom Fin fits if you're already on Intercom or want to put Fin on top of an existing help desk at $0.99 per outcome, Help Scout fits when support is mostly email and you want a hard monthly cap on AI spend, and eesel or Chatbase makes sense if you're staying on Zendesk or Freshdesk and want an AI layer bolted onto it.
Below, we compare ten tools using the prices and billing rules published by each vendor as of November 2026: what you're actually buying, whether there's a permanent free plan with AI answers, whether human handoffs cost money, and what the same three teams of two, five, and ten people pay each month.
Side-by-side comparison
| Tool | AI agent | What you are buying | Entry price, monthly billing | Free plan with AI answers | How the AI is billed | Handoff to a person |
|---|---|---|---|---|---|---|
| UserJot | Juno | Help desk with chat and email, plus feedback board and changelog | $0, $29, or $59 a workspace, flat | Yes, 3 teammates | No AI meter | Not billed |
| Intercom | Fin | Help desk; Fin also runs on other help desks | $39 a seat | No; 14-day trial | $0.99 per outcome | Free on request; a Procedure that ends in a handoff counts |
| Zendesk | AI agents | Help desk | $69 an agent | No; 14-day trial | $2 per automated resolution, $1.50 committed | Not billed |
| Help Scout | AI Answers | Help desk | $30 a user | Free plan for 5 users; AI free for an account's first 3 months | $0.75 per resolution | Not billed |
| Freshdesk | Freddy | Help desk | $35 an agent | No; 500 sessions once on paid accounts | $49 per 100 sessions | Billed; the session still counts |
| Tidio | Lyro | Help desk; Lyro is also sold alone | $29 a project, plus Lyro from $39 | 50 Lyro conversations once, never refilled | Monthly packs, $39 for 50 conversations to $700 for 1,000 | Billed once Lyro has replied |
| Crisp | Hugo | Help desk | $45 a workspace | No; the Free plan has no AI credits | Dollar credits spent on tokens, $5 to $75 a month included by plan | No fee; tokens already spent count |
| Chatbase | AI agent | AI layer; its own inbox from the $150 plan | $40 a workspace | 50 message credits a month | Message credits, $40 per 1,000 extra | No fee; credits already spent count |
| Wonderchat | AI agent | AI agent with its own inbox | $39 a workspace | 50 AI replies a month, 2 seats | AI replies by plan: 500, 3,000, or 10,000 a month | No fee; replies already sent count |
| eesel | eesel | AI layer on a help desk you already have | $299 a month for 500 credits | No; 7-day trial with 100 credits | 1 credit per ticket or chat worked, $0.80 per extra credit | No fee; a worked ticket costs its credit either way |
Entry prices in the table show the cheapest plan on monthly billing that includes live chat on your site, with the other tools' annual rates covered in their sections below.
How AI agents for customer support actually charge you
Before picking an agent based on its sticker rate, look at how the meter counts a conversation and what else has to sit underneath it:
- Per outcome or resolution. Help Scout charges $0.75 per resolution, Intercom charges $0.99 per outcome, and Zendesk charges $2 per automated resolution pay as you go or $1.50 on committed volume. Because most visitors read an answer in chat and close the tab rather than clicking a confirmation button, these tools count a thread as resolved when the customer stops replying.
- Prepaid sessions and conversation packs. Freshdesk sells Freddy in $49 packs of 100 sessions and Tidio sells Lyro in monthly packs starting at $39 for 50 conversations. Both deduct from your pack whenever the AI participates, regardless of whether the answer actually solved the customer's issue.
- Credits, replies, and tokens. Crisp spends monthly dollar credits on language model tokens, Chatbase deducts message credits per model request, Wonderchat sells fixed monthly buckets of AI replies, and eesel deducts one credit per ticket or chat worked. Picking a costlier model on Chatbase or Wonderchat, or letting Chatbase run multi-step Actions, burns through your monthly allowance faster.
- The help desk bill underneath. Eight tools on this list include the human support inbox, though Zendesk and Freshdesk advertise $19 annual email-only tiers while locking website chat behind pricier $55 and $29 annual seats. By contrast, eesel has no inbox for human teammates at all and Chatbase only unlocks its own inbox on its $150 plan, so you still pay for a separate help desk.
- What a human handoff costs. UserJot, Zendesk, and Help Scout charge nothing when a conversation escalates to a teammate. Freshdesk, Tidio, and eesel still count the session, conversation, or worked ticket once the AI has stepped in, Crisp, Chatbase, and Wonderchat keep the tokens or credits already spent before the escalation, and Intercom bills $0.99 if Fin finishes a configured Procedure that ends in a handoff.
1. UserJot
UserJot puts live chat and a shared inbox in the same workspace as your public feedback board, product roadmap, and changelog. Conversations, the live chat and shared inbox that Juno works in, is currently in beta and free on every plan while in beta.
On the Free plan, up to three teammates get website chat in the widget and inbound support email through a forwarding address in one inbox, alongside two feedback boards, a roadmap, and a changelog, with no cap on users or posts. Juno answers only from your product description, website crawls, and uploaded files, up to five knowledge sources per workspace, and replies in the language of the customer's latest message. You can tune her tone, length, formality, and emoji use, or switch her off for the workspace. Whenever a customer asks for a person, when your docs don't cover the question, when she isn't confident, or on a safety or policy matter, Juno hands the conversation off and can leave an internal summary for your team. Once a teammate replies, she stays out of the thread until someone hands it back to her, and she stays silent on spam, duplicates, and automated mail. Threads she answers on her own close after 30 minutes of silence on chat and 72 hours on email, and never auto-close after a teammate's reply or a handoff.
Unlike help desks that charge per agent seat and stack a per-resolution or credit meter on top, UserJot costs a flat $0, $29, or $59 a month for the workspace with no per-seat, per-resolution, per-conversation, or per-credit charge, and Conversations remains free on every plan while in beta. Starter at $29 covers up to 100 teammates and adds a custom domain, private boards, and moderation, while Professional at $59 adds JWT single sign-on, public identity masking, and removes the "Powered by UserJot" badge. The REST API and MCP server come with every plan, including Free. Because UserJot is built for software teams rather than omnichannel contact centers, Juno and the inbox cover widget chat and forwarded email only, with no WhatsApp, SMS, Messenger, Slack, or phone channels.
Best for: Small software and SaaS teams that want live chat, support email, an AI agent, and their product feedback board in one workspace at a flat monthly price.

2. Intercom Fin
Intercom's Essential plan starts at $39 a seat on monthly billing or $29 a seat billed annually, though as of November 2026 Intercom's pricing page strikes through that annual rate to $19 a seat for new customers. There is no permanent free plan, only a 14-day trial that doesn't ask for a card, and zero AI outcomes are included in the seat price.
Fin is billed on top at $0.99 per outcome, charged at most once per conversation. Intercom counts an outcome when the customer confirms their issue is solved, stops asking for help after Fin replies, or when Fin completes a configured workflow called a Procedure. If a customer asks to speak to a person, you pay nothing, with one catch: a completed Procedure still counts as a $0.99 outcome even when that Procedure ends by handing the customer off to your team.
If your team doesn't want to move its human inbox onto Intercom, Fin can also run on top of an existing help desk such as Freshdesk, Salesforce, or HubSpot with no seat fees and a minimum monthly commitment, given on the page as 50 outcomes. Admins can configure spending limits and alerts so a traffic spike doesn't run up an uncapped bill.
Best for: Teams already running Intercom, or teams keeping another help desk that want to bolt Fin onto it at $0.99 per outcome. Compare it in our Intercom alternative guide and Intercom pricing breakdown.
3. Zendesk
Zendesk advertises a $19 annual Support Team seat, $25 on monthly billing, but that plan only covers email tickets. Putting live chat on your site and turning on Zendesk's AI agents requires Suite Team at $69 per agent a month, or $55 on annual billing, after a 14-day trial with no free plan.
Team plans include five automated resolutions per agent each month. Once you pass those five, Zendesk charges $2 per automated resolution on pay-as-you-go billing, the highest per-resolution rate on this list, or $1.50 per resolution if you commit to a volume tier up front.
Zendesk bills only when the AI resolves a request on its own without escalating to a human agent, so handoffs never cost extra. Even so, at $2 per resolution on top of $69 monthly seats, the AI meter overtakes your seat bill as soon as your bot starts closing a meaningful share of tickets.
Best for: Larger support departments that already need Zendesk's ticketing suite and want strict escalation-free AI billing. See our Zendesk alternative page and Zendesk pricing guide.
4. Help Scout
Help Scout gives email-heavy teams two billing guardrails: new accounts get three months of AI resolutions free from signup, and workspace owners can set a hard monthly cap on resolutions that automatically switches AI Answers off for the rest of the cycle once reached.
Help Scout offers a permanent free plan for up to five users, one inbox, and one Docs site, capped at 100 contacts helped a month. Paid plans start on Standard at $30 a user on monthly billing, or $25 billed annually.
Once your initial three-month free window ends, AI Answers, now titled "Envoy" on Help Scout's pricing card, costs $0.75 per resolution and is billed at most once per conversation. If a customer asks follow-up questions, searches your docs again, or escalates to a teammate, Help Scout doesn't charge for the thread.
Best for: Email-first support teams that want per-resolution pricing at $0.75 with a hard monthly ceiling so the bill never runs past budget. Read our Help Scout alternative comparison and Help Scout pricing guide.
5. Freshdesk
Freshdesk prices its Freddy AI Agent by the session rather than the resolution, which changes what you pay when the bot gets stuck. Every paid account gets a one-time pool of 500 sessions to try Freddy, and after that you buy prepaid packs at $49 per 100 sessions.
Like Zendesk, Freshdesk's $19 annual Growth tier only handles email, and its free tier for two email agents expires after six months rather than lasting permanently. Getting website chat alongside Freddy requires moving to Freshdesk Omni Growth at $35 per agent monthly, or $29 on annual billing.
A single Freddy session covers the AI's replies within 24 hours on chat or 72 hours of the customer's first email. Because the meter tracks interactions rather than solved tickets, a session that ends in a handoff to a person still counts against your 100-session pack, and Freshdesk documents no monthly dollar cap.
Best for: Teams already buying Freshdesk Omni that prefer prepaid 100-session packs over open-ended per-resolution billing. Check our Freshdesk alternative page and Freshdesk pricing breakdown.
6. Tidio
Tidio counts a billable AI conversation the moment Lyro sends its first reply in a thread. If a visitor asks a hard question, Lyro gives an incomplete answer, and a teammate takes over right after, that chat still comes out of your monthly Lyro pack, and any chat that goes quiet for 15 minutes starts a brand-new billable conversation if the customer writes back.
For human chat, Tidio has a permanent free plan capped at 50 conversations a month, and Starter costs $29 a month, or $24.17 billed annually, for 100 conversations. Both Free and Starter include 50 Lyro conversations once for the life of the account; once they're gone, they never refill.
Continuing with Lyro means buying a monthly conversation pack starting at $39 a month, or $32.50 on annual billing, for 50 conversations and stepping up to $700 a month for 1,000 conversations, and Tidio also sells Lyro on its own for teams using another help desk. Watch your billing settings if you sign up on a monthly tier, because Tidio enables automatic tier upgrades by default.
Best for: Low-volume shops that fit inside a fixed monthly conversation pack, or teams buying Lyro standalone. See our Tidio alternative comparison and Tidio pricing guide.
7. Crisp
Instead of charging per seat and per resolution, Crisp sells fixed workspace tiers and meters Hugo, its AI agent, in dollar credits spent on tokens. Crisp's permanent free plan covers two seats and up to 100 customer profiles, but includes zero AI credits, so using Hugo starts on the $45 a month Mini workspace plan with four seats; Crisp doesn't list an annual rate on its pricing page.
Paid workspaces include $5 a month of AI credits on Mini, $25 on the $95 Essentials plan, and $75 on the $295 Plus plan. Crisp puts those allowances at around 90, 450, and 1,350 automated conversations, and separately estimates $0.05 to $0.10 a conversation.
Because the meter tracks raw token consumption, tokens spent before a human handoff count against your balance, and so do training runs and internal tests. When your monthly credits run out, Hugo stops answering and sends incoming chats straight to your team; pay-as-you-go overages are off by default and require setting a monthly spend limit if you switch them on.
Best for: Small teams of up to four or ten agents that want flat workspace seats and AI costs measured in cents rather than dollars per ticket. Read our Crisp pricing breakdown, and see how its Free plan compares in best free live chat software.
8. Chatbase
On its entry tier, Chatbase is an AI widget and model layer rather than a full help desk: you don't get Chatbase's own human helpdesk inbox or native connections to external help desks until you step up to the $150 plan.
Hobby costs $40 a month, or $32 a month billed yearly, for 700 message credits and two workspace members, and paid plans start with a 7-day trial. Chatbase also has a free plan with 50 message credits a month and one member, though it isn't shown on the pricing page. Stepping up to Basic at $150 a month, $120 billed yearly, gives you 4,000 credits, three members, Chatbase's built-in inbox, and integrations with Zendesk, Intercom, Freshdesk, and Help Scout, while Business costs $500 a month, $400 billed yearly, for 15,000 credits and five members; Basic and Business were still named Standard and Pro in October 2026.
Every call to the AI model spends message credits weighted by which model you choose, and an answer that triggers Actions can make several model requests inside one turn. There is no separate handoff fee, though credits spent before escalating stay spent, and auto-recharge packs add $40 per 1,000 extra credits whenever your balance drops below a threshold you set.
Best for: Teams building a custom-prompted AI agent with Actions that either stay inside Hobby's widget or connect Basic to an existing help desk.
9. Wonderchat
Wonderchat rebuilt its pricing around monthly AI replies in November 2026, pairing a permanent free tier with unlimited human seats on every paid plan. Its free plan, which Wonderchat describes as free forever, includes 50 AI replies a month, one AI agent, two team seats, and a built-in shared inbox with live chat handover to your team.
Paid plans unlock unlimited team seats and scale by reply volume: Starter costs $39 a month, or $32.50 billed yearly, for 500 AI replies; Basic costs $149 a month, $125 billed yearly, for 3,000 replies and adds integrations with Zendesk and Freshdesk; and Scale costs $499 a month, $417 billed yearly, for 10,000 replies. Wonderchat's own estimates put those three paid tiers at roughly 160, 600, and 1,800 resolutions a month.
Generating one reply uses one credit on Wonderchat's fast models and more than one on frontier models, and any replies sent before a human handoff count toward your monthly total. When you use up your allowance, the agent stops replying to customers, and the pricing page publishes no top-up pack price.
Best for: Teams with lots of occasional human operators that want unlimited seats on a $39 plan and a hard stop when monthly AI replies run out.
10. eesel
eesel doesn't include a human inbox at all. It is a pure AI layer built to work inside a help desk you already pay for, including Zendesk, Freshdesk, Intercom, and Help Scout, with no per-seat fee and no platform fee on its own side.
There is no permanent free plan, only a 7-day cardless trial with 100 credits. Paid Teammate bundles start at $299 a month for 500 credits and step across ten sizes up to $1,749 a month for 5,000 credits, with two months free when billed yearly, while Enterprise adds $1,000 a month on top of whichever Teammate bundle you pick.
Every ticket the agent works on counts as one credit, and every customer chat counts as one credit, whether the AI closes it or hands it off to your team. If your workspace hits zero credits, eesel pauses your agents until the credits reset, unless you turn on optional overages at $0.80 per extra credit up to a monthly cap you set.
Best for: Established support teams staying on Zendesk or Freshdesk with enough ticket volume to justify a $299 monthly AI floor.
What the best AI customer service software costs at 2, 5, and 10 agents
Headline seat prices and per-resolution rates are hard to eyeball together because one scales with your team size and the other scales with your customer traffic. To put the seven help desks on equal footing, here is the monthly bill for three teams on each vendor's cheapest plan with live chat, in a scenario where the AI agent resolves 30% of incoming conversations: 150 resolutions a month for the two-agent team, 600 for the five-agent team, and 1,500 for the ten-agent team. You can trace the underlying seat and pack arithmetic in our help desk pricing comparison, and see how each vendor defines a billable resolution, session, or credit in customer service chatbot pricing. Freshdesk is on Omni Growth here because its cheaper Growth seat is email only, which adds $12 an agent to its figures in that comparison.
| Tool | 2 agents, 500 conversations | 5 agents, 2,000 conversations | 10 agents, 5,000 conversations |
|---|---|---|---|
| UserJot | $0 | $29 | $29 |
| Crisp | $48 to $55 | $100 to $130 | $145 to $220 |
| Freshdesk | $168 | $469 | $1,085 |
| Help Scout | $173 | $600 | $1,425 |
| Tidio | $199 | $774 | Not published |
| Intercom | $227 | $789 | $1,875 |
| Zendesk | $418 | $1,495 | $3,590 |
Watch what happens between the first column and the third. At ten agents and 5,000 conversations, the AI usage meter overtakes the human seat bill on every per-resolution help desk: $1,485 of Intercom's $1,875 monthly total, $2,900 of Zendesk's $3,590 total, and $1,125 of Help Scout's $1,425 total go to AI resolutions. Tidio's ten-agent cell reads "Not published" because its self-serve conversation ladder stops before 5,000 conversations. UserJot stays at $0 for two teammates on Free and $29 flat on Starter for both five and ten teammates, while Conversations is free on every plan during beta.
Chatbase, Wonderchat, and eesel aren't in that grid because Chatbase and eesel usually sit on top of a help desk you're already paying for, and none of the three publishes a flat per-conversation rate that multiplies across those three volumes. For a rough benchmark at the middle team's 600 AI conversations a month, Wonderchat puts its $149 Basic plan at around 600 resolutions, while eesel's smallest $299 bundle covers 500 worked tickets or chats before counting your underlying help desk seats.
Enterprise AI agents: Ada, Sierra, and Decagon
Three more names come up whenever AI support agents are discussed: Ada, Sierra, and Decagon. We left all three out of the ten-tool table above for the same reason: none of them publishes a price, offers a free plan, or lets a small team sign up self-serve. Every one of them points prospective buyers to a demo instead of a signup page and plugs into an existing enterprise help desk or contact-center stack rather than replacing a small team's inbox.
Each vendor makes its target buyer plain on its own website. Ada calls itself "The AI customer service platform built for enterprise" for high-volume regulated industries and connects to platforms like Zendesk, Freshworks, and Twilio. Sierra says "40% of the Fortune 50 partner with Sierra." Decagon describes itself as "Powering concierge experiences for the world's leading enterprises."
Even without public dollar figures, their published pricing models follow the same split as the self-serve tools above. Ada defaults to conversation-based billing where "you pay for every conversation your AI agent has with end users", with resolution-based contracts available on request. Decagon offers either a fixed rate on every incoming conversation or a higher rate per resolved conversation with free escalations, and notes: "The vast majority of our customers choose per-conversation pricing." Sierra sells outcome-based contracts tied to results like a resolved support conversation or a saved cancellation, adding that "if a case needs to be escalated, in most cases, there's no charge."
When a customer sends your AI support agent a feature request
In a software company, plenty of incoming support chats aren't questions your documentation can answer. A customer hits a workflow your product doesn't support yet, or runs into a bug, and types it straight into the chat widget.
When the help desk and the feedback board are separate products, that request usually ends with a handoff. On Freshdesk, Tidio, or eesel, that detour still burns a session, conversation, or credit. Then a teammate replies to thank the customer, copies the idea into a separate backlog tool, and the original chat loses all connection to whether the feature ever ships.
Because Juno works inside the same workspace as UserJot's public feedback board, feature requests don't hit a dead end in chat. When a customer asks for something your product doesn't have yet, Juno searches your public feedback board, shows the matching request right in the conversation, or drafts a new one if nothing matches. Only after the customer confirms does she add their vote or create the new request. Months later, when your team ships that feature and updates the request's status to Completed, UserJot automatically emails everyone who posted, voted, or commented on it.

Frequently asked questions
Which is the best AI customer service agent?
For small software and SaaS teams, UserJot is the best pick because Juno is included on every plan at a flat $0, $29, or $59 a month for the workspace, with no per-resolution fee and Conversations free on every plan while in beta. Teams already on Intercom or looking to add an agent onto another help desk can use Intercom Fin at $0.99 per outcome, while Help Scout fits email-focused teams that want $0.75 resolutions with a monthly spend cap. If you want to keep Zendesk or Freshdesk and add an AI layer without per-seat charges, eesel starts at $299 a month for 500 worked tickets or chats.
How much does an AI agent for customer service cost?
Most vendors charge either $0.75 to $2 per resolved conversation or sell monthly bundles of sessions, conversations, replies, or credits that start between $39 and $299, usually on top of your human help desk seats. Help Scout charges $0.75 per resolution, Intercom charges $0.99 per outcome, and Zendesk charges $2 pay as you go or $1.50 committed, while Freshdesk sells $49 packs of 100 sessions and Crisp deducts tokens from $5 to $75 in monthly plan credits. UserJot includes Juno at $0, $29, or $59 flat per workspace with no AI usage meter, while Conversations is free on every plan during beta.
Which AI support agents have a free plan?
Three tools on this list offer a permanent free plan with recurring AI answers: UserJot covers up to three teammates with Juno included while Conversations is in beta, Wonderchat includes 50 AI replies a month and two seats, and Chatbase has a free tier with 50 monthly message credits for one member that its pricing page doesn't show. Help Scout, Tidio, and Crisp also run permanent free help desk plans, though Help Scout's free AI resolutions expire after three months, Tidio's 50 Lyro conversations never refill once spent, and Crisp includes zero AI credits on Free. Intercom, Zendesk, Freshdesk, and eesel only offer time-limited trials.
Do you pay when an AI support agent hands off to a person?
That depends on whether the vendor meters outcomes or attempts. UserJot, Zendesk, and Help Scout charge nothing when a thread escalates to a teammate, and Intercom charges nothing when a customer asks for a person unless Fin completed a configured Procedure that ends in a handoff. Freshdesk, Tidio, and eesel still count the session, conversation, or worked ticket once the AI has engaged, while token and credit tools like Crisp, Chatbase, and Wonderchat keep whatever credits were spent before the escalation.
Do you need a help desk as well as an AI agent?
Only if you buy a standalone AI layer, because someone on your team still needs a shared inbox to handle the conversations the AI escalates. UserJot, Intercom, Zendesk, Help Scout, Freshdesk, Tidio, Crisp, and Wonderchat all include a human inbox alongside the AI agent, and Chatbase adds its own helpdesk inbox starting on its $150 Basic plan. eesel has no inbox for human agents, and like Ada, Sierra, and Decagon it connects to a help desk you already pay for.
How is AI used in customer service?
Software teams mainly put an AI agent at the front of live chat and support email to answer repetitive documentation questions at any hour and hand account-specific or unfamiliar problems to a person. When a question is covered by your docs, the agent answers, and when it isn't confident or the customer asks for a teammate, it steps aside with context so your team isn't typing out the same setup steps all week. Tools like Intercom Fin and Chatbase also let the agent run configured workflows or API Actions before answering or escalating.
What are the best chatbots for customer service?
Modern AI agents answer directly from your documentation rather than walking visitors through fixed decision trees, and UserJot's Juno is the all-in-one option for SaaS teams that want flat workspace pricing across live chat, email, and product feedback while Conversations is free in beta. Among metered help desk bots, Intercom's Fin at $0.99 per outcome and Help Scout's AI Answers at $0.75 per resolution bill per resolved thread rather than per reply, while Crisp's Hugo keeps token costs around $0.05 to $0.10 per estimated conversation on workspace plans starting at $45 a month.
