AI chatbots for customer support list at $0.05 to $2 per conversation or resolution in 2026, depending on the vendor and the unit it bills. Most also need a help desk plan, so the monthly bill is the platform plus the AI volume times the unit price, and two tools with similar unit prices can end up far apart at your volume.
This guide explains the five billing units, lists AI prices from ten vendors and Gleap, works through three team sizes and shows the costs that sit outside the unit price. All prices are USD list prices from each vendor’s own pages, checked on September 27, 2026. It covers AI chatbots for customer support; subscriptions to general assistants such as ChatGPT or Claude are priced per user and are a different product.
How AI chatbots are priced: five billing units
Every AI chatbot bill counts something. The unit decides what you pay for and how the bill grows with your volume.
Per resolution or outcome
You pay when the AI settles a conversation, by the vendor’s definition. Intercom charges $0.99 per Fin outcome: the customer confirms the issue is resolved, does not ask for more help after Fin responds, or Fin completes a workflow, including a handoff. It charges at most once per conversation. Help Scout charges $0.75 per resolution and counts one only when the customer gets an AI answer and does not escalate, search the knowledge base, ask more questions or say they need more help.
Since April 14, 2026, HubSpot’s Customer Agent uses 50 HubSpot credits per resolved conversation, which HubSpot prices at $0.50 (HubSpot announcement). Zendesk bills verified resolutions, which a language model confirms after the conversation ends, against a dollar allowance that comes with each agent seat (About automated resolution tiers).
The definitions differ, so read them before you compare prices. A Fin outcome can include a handoff to your team, while a Help Scout resolution does not count once the customer asks for more help.
Per conversation or session
You pay for every conversation the AI joins, whether it resolves it or not. Freshdesk bills Freddy AI Agent by session: all chat interactions within 24 hours count as one session, and an email session is a 72-hour window from the customer’s first email. Sessions cost $49 per 100 after 500 free sessions per account. Tidio bills every conversation with at least one Lyro reply, $0.70 to $0.78 each on monthly plans. Salesforce sells Agentforce conversations at $2 each, and Front lists Autopilot from $0.05 per conversation.
Per seat
Some tools put the AI into the per-user price with a monthly cap. ChatBot, from Text, includes 10 AI resolutions a month on Essential at $19 per user a month and 200 on Growth at $79, billed annually, and 50 more resolutions cost $49.50.
AI for your own agents is usually billed per seat as well. Copilots, the AI assistants that work next to your team in the inbox, cost $50 per agent a month at Zendesk and $29 at Intercom and Freshdesk, billed annually, and $20 per seat a month at Front.
Per message or action
A few tools count each AI reply or action. Chatbase sells message credits, and each AI reply uses 1 to 6 credits depending on the model (Chatbase FAQ). Its Standard plan costs $150 a month with 4,000 credits on monthly billing, and extra credits cost $40 per 1,000. Salesforce also sells Agentforce by action: an action uses 20 Flex Credits, and Flex Credits cost $500 per 100,000, so an action costs $0.10.
Prepaid credits by usage
Usage billing charges for the AI work itself. Gleap deducts each task from a prepaid credit balance by the tokens it uses and the model that runs it, so there is no fixed price per message or conversation. A short answer costs less than a long conversation with several tool calls. As of September 2026, a conversation with Kai, Gleap’s AI support agent, averages about $0.05. Real usage varies.
AI chatbot prices by vendor
List prices from the vendors’ own pages, checked on September 27, 2026. The units differ, so use the table to see what each bill depends on, then compare monthly totals for your own volume.
| AI agent | Billing unit | AI price | Platform it runs on |
|---|---|---|---|
| Intercom Fin AI Agent | Outcome, at most one per conversation | $0.99 per outcome | Intercom seats, $29 to $132 per seat a month, billed annually |
| Zendesk AI agents | Verified resolution | Allowance of $2 to $10 per agent seat a month, then pay as you go; price per resolution not published | Zendesk plans, $19 to $115 per agent a month, billed annually |
| Freshdesk Freddy AI Agent | Session: 24 hours of chat or 72 hours of email | 500 sessions free once, then $49 per 100 sessions | Freshdesk Omni, $29 to $119 per agent a month, billed annually |
| HubSpot Customer Agent | Resolved conversation, paid in HubSpot credits | 50 credits, $0.50, per resolved conversation | A Professional or Enterprise hub; Service Hub Professional from $90 per seat a month on an annual commitment |
| Help Scout AI Answers | Resolution | $0.75 per resolution; unlimited for a new account’s first three months | Help Scout plans from $25 per user a month, billed annually |
| Tidio Lyro | Conversation with at least one Lyro reply | $0.70 to $0.78 per conversation on monthly plans; 50 free once | Tidio plans from free, priced by the conversations your team answers |
| Salesforce Agentforce | Conversation, or action | $2 per conversation, or $0.10 per action through Flex Credits | Salesforce, with editions and add-ons priced separately |
| Front Autopilot | Conversation | From $0.05 per conversation, quoted by sales | Front seats, $25 to $105 per seat a month, billed annually |
| ChatBot | AI resolutions included per user | 10 a month on Essential, 200 on Growth; 50 more for $49.50 | $19 or $79 per user a month, billed annually |
| Chatbase | Message credits, 1 to 6 per AI reply by model | 4,000 credits on Standard; $40 per 1,000 extra | $40 to $500 a month on monthly billing |
| Gleap Kai | Tokens used, by model, from prepaid credits | No fee per conversation or outcome; about $0.05 per conversation on average, and real usage varies | Gleap plans from $49 a month billed annually; unlimited seats from Team at $149 |
Two notes on the table. Intercom showed some visitors a $19 Essential seat price as a price experiment on the day we checked; the table uses the standard $29. Free allowances run out: Freshdesk’s 500 sessions and Tidio’s 50 Lyro conversations come once per account, and Help Scout’s unlimited AI Answers last three months.

What else goes into the bill
The unit price is one line. These are the others:
- Seats. Per-seat help desks grow with every person who needs access, including part-time helpers and engineers who look at tickets.
- Copilot seats. Agent-side AI is often a separate per-seat add-on, from $20 to $50 per agent a month at the vendors above.
- Minimums and plan requirements. Fin on another help desk has a minimum monthly commitment; Intercom gives 50 outcomes as an example. HubSpot’s Customer Agent needs a Professional or Enterprise subscription, and Service Hub Professional adds a one-time onboarding fee of $1,500.
- Limits and defaults. At Zendesk, resolutions beyond the allowance are billed pay as you go unless you turn overage off, and unused allowance does not carry over. HubSpot credits reset every month, unused credits expire, and by default usage-based features pause when the included credits run out (HubSpot credits and billing).
- Two meters on one conversation. Tidio bills the conversations your team answers and the conversations Lyro answers separately, so a conversation that Lyro starts and a person finishes can count on both.
- Channels and messages. WhatsApp, SMS and phone are often billed by usage; Intercom, for example, bills email campaigns, SMS, WhatsApp and phone pay as you go.
- The content the AI answers from. An AI chatbot needs current help content. Check which plan includes the help center or knowledge sources you plan to connect.
Before you forecast, check what counts as billable, what happens at the limit and which free allowances expire.
How to estimate your monthly cost
A monthly AI support bill has four parts: the platform plan, the AI billing unit, the AI volume and the add-ons. Put them in one formula:
Monthly cost = platform + (AI conversations × billable share × unit price) + add-ons
- Count the conversations the AI would take. Use the last three to six months of chats and emails, not only the busy weeks.
- Estimate the billable share. With per-resolution pricing you pay for the share the vendor counts; with per-conversation pricing you pay for all of them.
- Price the platform for the seats you need, at the billing period you will sign.
- Add the extras: copilot seats, channels, emails, onboarding fees and minimums.
- Test on your own tickets. Run a representative set of real questions in a trial and read the usage report before you commit.
Worked examples for three team sizes
These examples use annual list prices from September 27, 2026, before tax. Assumptions, not vendor figures: the AI takes every conversation first; 60% of AI conversations end in a billable Fin outcome; each Freshdesk conversation is one session and the 500 free sessions are used up; Gleap’s AI line uses its published average of about $0.05 per Kai conversation.
| Team | Intercom Essential with Fin | Freshdesk Omni Growth with Freddy AI Agent | Gleap Team with Kai |
|---|---|---|---|
| 3 agents, 500 AI conversations a month | $87 + $297 = $384 | $87 + $245 = $332 | $149 + about $25 = about $174 |
| 10 agents, 2,000 AI conversations a month | $290 + $1,188 = $1,478 | $290 + $980 = $1,270 | $149 + about $100 = about $249 |
| 25 agents, 5,000 AI conversations a month | $725 + $2,970 = $3,695 | $725 + $2,450 = $3,175 | $149 + about $250 = about $399 |
The first number in each cell is the platform, the second the AI usage. Three cautions:
- Gleap’s AI line is an average, not a price. Longer conversations, larger context, tool calls and premium models cost more.
- Plans are not equal. Each plan includes different features, and larger teams on per-seat tools often need a higher plan, which raises the seat line.
- Zendesk is left out because it does not publish its price per resolution.
The pattern matters more than the totals. Per-seat tools grow with the team, per-unit AI grows with the volume, and a workspace price with unlimited seats stays the same as the team grows.
Building your own AI chatbot: the cost drivers
Many guides to chatbot cost quote build prices from development agencies. A custom build replaces the vendor’s unit price with your own costs:
- Model usage. Model providers price their APIs per million input and output tokens. Every question sends your instructions and the matching help content along, so context size and model choice drive this line.
- Retrieval. Your help content has to be indexed for search, stored and kept in sync when articles change.
- The chat surface. A widget for your website and apps, plus every other channel you answer on.
- The handoff to people. An inbox or help desk integration, so a teammate can take over with the conversation history.
- Quality work. Test sets, answer reviews and fixes for wrong answers, every week.
- Security and privacy. Access controls, data processing terms and logs.
- Engineering time. The build, and the maintenance after launch.
Ask for a quote broken down by these lines, and compare it with a year of vendor pricing at your volume.
How Gleap prices Kai
Kai, Gleap’s AI support agent, is on every Gleap plan. Gleap charges a monthly plan for the workspace and bills AI usage separately through prepaid credits, deducted by the tokens and model each task uses. There is no fixed price per message, conversation or outcome.
- Kai$9.60
- Kai Code$11.20
- Kai Resolve$5.80
- Agents$2.15
As of September 2026, Starter costs $49 per month billed annually ($59 monthly) with one seat and one project. Team costs $149 per month ($179 monthly) with unlimited seats and projects, Pro $299 ($359) and Enterprise from $999 (from $1,199).
Every Gleap agent draws from the same credit balance. These are the published averages per task:
| Task | Average credits | Plan |
|---|---|---|
| Kai answers a support conversation | About $0.05 per conversation | Every plan; premium models cost more |
| Kai Resolve investigates a hard ticket | About $0.50 per ticket with a code investigation | Pro and Enterprise |
| Kai Code codes a change to a pull request | Your own Claude Code, Codex or Cursor subscription with Kai Code Bridge, or about $2 to $5 per Kai Code Cloud session, depending on complexity | Pro and Enterprise |
The averages are as of September 2026, priced at current credit rates before bonus credits. They are not a quote: real usage depends on many factors, such as the complexity of the task, the model, the context and the length of each conversation or session.
- Bonus credits. Pro and Enterprise add 25% bonus AI credits to eligible purchases: a $100 purchase adds $125 to the balance. It is a credit bonus, not a discount on token prices.
- Trial. The 14-day free trial includes $50 in AI credit. There is no free plan.
- Top-ups. Auto-recharge is on by default for paid workspaces, and you can change it or turn it off in Billing. It does not run during the trial. When credits run out, AI work pauses until credits are added.
- Emails. Emails to customers are billed at $2 per 1,000.
The trade-offs are real. Gleap has no free plan, and Starter has one seat. The knowledge base, the WhatsApp, Instagram, Messenger, Slack and Telegram channels, Kai Copilot and tools for Kai need Team. Kai Resolve, Kai Code and Kai PM need Pro. AI usage comes on top of every plan, so run a representative set of your own tickets in the trial and read the usage breakdown in Billing before you set a budget.
