Rank 1 · Best overall
Intercom Fin
An AI agent priced per resolved conversation that runs on Intercom's help desk or alongside another one.
intercom.com8.5
out of 10
Best for: Support teams with steady ticket volume that want to pay only when the AI actually resolves a conversation.
Fin is the most complete AI support agent for a team that already handles a few hundred conversations a month. Intercom prices it at $0.99 per outcome on every plan, and an outcome is only counted when the customer confirms the issue is solved or leaves without asking for a person. If Fin cannot answer, fails an action or the customer asks for a human, you pay nothing. That model lines up the bill with real work done, and the pricing page lets you set spending limits and alerts so a spike does not surprise you.
The trade-off is that cost scales with success: the more Fin resolves, the more you pay, and teams with thousands of simple questions a month may find a flat-priced tool cheaper. Intercom's own help desk seats start at $29 per seat per month, with a new-customer discount on annual billing, and Copilot for human agents is a separate $29 per agent add-on. You can also run Fin on top of another help desk, which makes it the easiest premium option for teams that do not want to migrate. Choose Fin if answer quality and handoff matter more than the lowest possible bill.
Standout feature
You are only billed when Fin resolves a conversation, never when it fails or hands off to a person.
Use cases
SaaS support teams
Let Fin answer account and billing questions in chat
Outcome: Fewer tickets reach human agents
Teams on another help desk
Add Fin without migrating the inbox
Outcome: AI resolutions with no seat change
Early-stage startups
Apply for the Early Stage discount
Outcome: Intercom at a fraction of list price
Key features
- Fin AI Agent billed per outcome, not per seat
- Works with Intercom's help desk or other tools such as Salesforce
- Copilot AI assistant for human agents in the inbox
- Fin Voice for phone support, available through sales
- Spending limits and alerts on usage
Pros
- You pay nothing for conversations Fin cannot answer or that go to a human
- Can be added to an existing help desk without switching
- Startups under the Early Stage program get a large discount
Cons
- Costs grow directly with volume, so a busy month means a bigger bill
- Fin used on its own has a minimum monthly commitment
- Copilot and proactive features are paid add-ons
Rank 2 · Runner-up
Tidio
Live chat and help desk for small businesses with Lyro, an AI agent sold as an add-on or on its own.
tidio.com8.5
out of 10
Best for: Small online stores that want live chat and an affordable AI agent in one tool.
Tidio is the easiest AI support setup on this list for a small store. You can install the chat widget on the free plan, then add Lyro, Tidio's AI agent, which answers from your knowledge base, matches a communication style you choose and hands off to a human when needed. Lyro is also sold as a stand-alone product starting at $32.50 a month for 50 AI conversations, and paid help desk plans begin at $24.17 a month.
The limitation is volume. Lyro is metered by AI conversations, so a store with hundreds of chats a day will need to step up tiers, and the Plus plan starts at $300 a month plus usage. Reporting and workflow depth are also lighter than Intercom or Zendesk. For a shop doing up to a few hundred support chats a month, though, Tidio gives you chat, an inbox, automation Flows and a capable AI agent for less than most rivals charge for the AI alone.
Standout feature
A free plan plus an AI agent from $32.50 a month makes Tidio the cheapest credible starting point for small stores.
Use cases
Small ecommerce stores
Answer shipping and return questions with Lyro
Outcome: Replies outside business hours
Solo founders
Run live chat on the free plan
Outcome: Customer chat at no cost
Marketing teams
Capture leads with Flows
Outcome: More contacts from site visitors
Key features
- Lyro AI agent with knowledge-based responses
- Human handoff and customizable communication style
- Live chat, shared inbox and macros
- Flows for no-code automation and lead capture
- Free plan to start
Pros
- Free plan and low-cost Starter make it cheap to try
- Very quick to install on common store platforms
- Lyro can be bought without the full help desk
Cons
- AI is metered by conversations, so busy stores need higher Lyro tiers
- Plus plan jumps to $300 per month plus usage
Rank 3 · Also great
Chatbase
A builder for AI support agents trained on your own content, with a helpdesk inbox, voice and API on higher plans.
chatbase.co8.3
out of 10
Best for: Teams that want a flexible AI agent trained on their docs and deployed across their site and apps.
Chatbase is one of the best-known tools for building an AI agent from your own content, and it shows in how quickly you can get one running. Upload docs or point it at your site, choose a model and embed the agent. Hobby costs $40 a month, or $32 billed yearly, for 700 message credits and two members, and the next tier at $150 adds the Chatbase Helpdesk inbox, voice, advanced integrations and API access.
Where Chatbase gets expensive is in the extras. Additional message credits are $40 per thousand, extra agents are $25 each per month, and removing the Chatbase branding is $99 a month. There is also no permanent free plan, only a 7-day trial. If you want a polished agent builder and plan to use voice or the API, Chatbase is a strong pick. If you only need a basic site bot, SupportGPT and AgentStack offer similar building blocks for less.
Standout feature
Voice and API access arrive on the $150 plan, which is unusual for an agent builder at that price.
Use cases
SaaS teams
Train an agent on product docs
Outcome: Instant answers to how-to questions
Developers
Call the agent through the API
Outcome: AI support inside their own app
Small support teams
Escalate to the Chatbase Helpdesk inbox
Outcome: Humans pick up where AI stops
Key features
- AI agents trained on your files, sites and other sources
- Access to advanced models on all paid plans
- Chatbase Helpdesk inbox, voice and API access from the second tier
- Add-ons for extra agents, credits and branding removal
- Integrations and analytics
Pros
- Fast to train and deploy a working agent
- Clear credit-based plans with a 7-day trial
- Voice and API available without an enterprise contract
Cons
- No permanent free plan
- Removing Chatbase branding costs an extra $99 per month
Rank 4
Mava
AI support and a shared inbox built for Discord, Telegram, Slack, email and web chat communities.
mava.app8.2
out of 10
Best for: Web3, gaming and developer communities that handle support in Discord or Telegram.
Mava solves a problem the big help desks mostly ignore: support that happens inside Discord, Telegram and Slack communities. It pulls those channels into one inbox with email and web chat, and puts an AI agent in front that answers from your training sources. On the Growth plan you can even train the AI on past Discord replies, which suits communities where the best answers already live in old threads.
Pricing is per workspace rather than per seat. The free plan includes all channels but only 30 support requests a month; Founder is $39 for 100 requests and three seats; Growth at $99 adds unlimited seats and 500 requests. Features like the multi-lingual AI bot, webhooks and API access only arrive on Scale at $199. If your users are in Discord or Telegram, Mava is the best tool here; if they mostly email, a general help desk will do more.
Standout feature
It treats Discord and Telegram as first-class support channels and can learn from your past Discord replies.
Use cases
Web3 projects
Answer token and wallet questions in Discord
Outcome: Faster replies in busy servers
Gaming studios
Route Telegram and Discord tickets to one inbox
Outcome: No missed player reports
Developer tools
Train AI on past community answers
Outcome: Repeat questions answered automatically
Key features
- One inbox for Discord, Telegram, Slack, email and web chat
- AI agent trained on your sources, including Discord replies on Growth
- Scripted AI replies and template answers
- Multi-lingual AI bot, SDK, webhooks and API on Scale
- Unlimited seats from the Growth plan
Pros
- Native community channels that most help desks ignore
- Priced per workspace, with unlimited seats from Growth
- Free plan covers every channel
Cons
- Free plan is capped at 30 support requests a month
- Multi-lingual AI and API access wait until the $199 Scale plan
Rank 5
AgentStack
A support agent your coding agent sets up from one prompt, answering on chat, email, Slack and phone.
agentstack.build8.1
out of 10
Best for: Developer-led teams that already work in Claude Code, Codex or Cursor and want support live in minutes.
AgentStack takes an unusual approach: instead of a builder with setup screens, you paste one line into Claude Code, Codex or Cursor and your coding agent does the setup. It reads AgentStack's instructions, crawls your docs, PDFs, spreadsheets and Notion, writes the chat widget into your codebase and connects email, Slack and phone. Unanswered questions are surfaced so you can fill gaps in your docs, and a human can take over when needed.
Pricing is by messages rather than seats. The free plan gives 50 messages to start, Hobby is $30 a month for 1,500 messages, Standard is $100 for 10,000 messages with three agents and a support inbox, and Pro is $400. Top-ups cost $20 per 1,000 credits. The add-ons are pricey for a small team: a custom domain and removing branding are $99 a month each. If your team lives in a code editor, AgentStack is the fastest route to a multi-channel agent on this list.
Standout feature
It is the only tool here you can set up entirely from inside your coding agent, with no account required to start.
Use cases
Indie developers
Ask Claude Code to set up a support agent
Outcome: Live widget in one session
Small SaaS teams
Answer chat, email and Slack from one agent
Outcome: One knowledge base for every channel
Docs owners
Review unanswered questions
Outcome: Gaps in docs get fixed
Key features
- Setup by pasting one prompt into Claude Code, Codex or Cursor
- Crawls your site, PDFs, Office files and Notion
- Answers on chat, email, Slack and phone with human handoff
- Choice of models including Claude, Gemini and GPT
- Surfaces questions the agent could not answer
Pros
- No account or forms needed to start
- Priced by messages, never per seat
- Embed code is written straight into your repo
Cons
- Custom domain and branding removal are $99 per month each
- Built around coding agents, so non-technical teams may prefer a dashboard-first tool
Rank 6
Zendesk AI Agents
AI agents built into Zendesk's Support and Suite plans, billed by automated resolutions on top of agent seats.
zendesk.com8.1
out of 10
Best for: Larger support teams already on Zendesk, or moving to it, that want AI and ticketing from one vendor.
Zendesk is the safe choice for a support organization that wants AI agents inside a mature ticketing system. AI agents for messaging are part of every Support and Suite plan, and billing is based on automated resolutions: conversations the AI closes without a human. Plans start at $19 per agent per month billed yearly for Support Team, with Suite Team at $55 and Suite Professional at $115, so you get routing, triggers, a help center and reporting alongside the agent.
The catch is the size of the included AI allowance. The pricing page lists 5 automated resolutions per agent per month on the lower plans and 10 on Suite Professional, so most teams will need to commit to more. Copilot for human agents is another $50 per agent per month. Setup also takes longer than with chat-first tools like Tidio or Chatbase. If you already run Zendesk, turning on its AI agents is the obvious first test; if you are starting from scratch with a small team, a lighter tool will be cheaper and faster.
Standout feature
AI agents come with every Zendesk Support and Suite plan, so existing customers can test them without a new contract.
Use cases
Existing Zendesk customers
Turn on AI agents in messaging
Outcome: Automated answers inside current workflows
Multi-team support orgs
Route tickets with triggers and AI
Outcome: Right ticket reaches the right team
Contact centers
Combine voice, messaging and AI on one platform
Outcome: One record per customer
Key features
- AI agents for messaging across web, in-app chat and social channels
- Automated resolutions included on each plan, more can be committed
- Copilot add-on to assist human agents
- Automations and triggers for ticket routing
- Contact Center and workforce engagement add-ons
Pros
- AI agents ship with every Support and Suite plan
- One vendor for ticketing, help center, messaging and AI
- Scales to large, multi-team support operations
Cons
- Included automated resolutions are small, 5 to 10 per agent per month
- Copilot and quality tools are extra per-agent add-ons
- More setup work than lightweight chat-first tools
Rank 7
Can I Help
An AI customer concierge for Shopify merchants that answers chat, email and phone.
canihelp.ai8.0
out of 10
Best for: Shopify stores that want one AI agent covering chat, email and voice calls.
Can I Help is an AI concierge aimed at Shopify merchants and small to mid-size businesses. It handles chat and email on the $59 Starter plan, and the $179 Growth plan adds AI voice so the same agent can answer phone calls. A no-code builder lets you set the agent's personality, knowledge, workflows and standard operating procedures, and AI Agent Assist drafts replies for your human team at no extra charge.
Credits are the thing to model before you buy. A chat or email conversation costs about 10 credits and a voice call about 50, so Starter's 1,000 credits cover roughly 100 AI conversations a month, and a phone number uses 50 credits a month on its own. The free plan is a text helpdesk with no AI credits, useful for setup but not for testing the agent at volume. For a Shopify store that wants chat, email and phone from one AI, it is a sensible all-in-one; stores with heavy chat volume should compare per-conversation cost with Tidio.
Standout feature
One AI agent answers chat, email and phone calls for a Shopify store, with unlimited team members.
Use cases
Shopify merchants
Answer order questions in chat and email
Outcome: Fewer where-is-my-order emails
Stores taking phone calls
Let AI voice answer the store line
Outcome: Calls answered around the clock
Support staff
Use Agent Assist drafts
Outcome: Faster human replies
Key features
- AI chat and AI email on paid plans
- AI voice that answers phone calls on Growth
- AI Agent Assist drafts replies for human agents
- No-code builder for personality, knowledge and workflows
- Unlimited team members on all plans
Pros
- One agent covers chat, email and phone
- Unlimited team members on every plan
- Thought logs show how each answer was reached
Cons
- Free plan includes no AI credits
- Voice is only on the $179 Growth plan and uses about 50 credits per call
Rank 8
SignalZen
Flat-priced AI support and live chat for small businesses, controllable from Slack, Teams or Google Chat.
signalzen.com8.0
out of 10
Best for: Small businesses that want unlimited AI chats for one predictable monthly price.
SignalZen is built for small businesses that want AI support without metered pricing. Every plan includes unlimited chats and bandwidth and the full set of AI features: AI support answers, an AI Copilot for your team, summaries and translation. The differences between plans are operator seats and subdomains, from two operators on the $29 Starter plan to unlimited operators on Pro at $99. A help center site, saved replies and webhooks come with all of them.
The standout feature is answering from where your team already works: chats can be controlled from Slack, Microsoft Teams or Google Chat, so a small team does not need to watch another dashboard. The trade-off is depth. SignalZen has fewer integrations and automated actions than Intercom or Tidio, so it suits question answering more than order lookups. For a small company that hates usage bills, its flat price is hard to beat.
Standout feature
Unlimited conversations and every AI feature on a $29 plan, with no usage fees.
Use cases
Small service businesses
Answer site chats from Slack
Outcome: No new dashboard to watch
Founders
Run AI support on a flat $29 plan
Outcome: Predictable monthly cost
International teams
Use AI translation in chats
Outcome: Support in more languages
Key features
- AI support, AI Copilot, summaries and translation on every plan
- Unlimited chats and bandwidth on all plans
- Reply to customers from Slack, Microsoft Teams or Google Chat
- Help Center website included
- Saved replies and webhooks
Pros
- No per-conversation or per-resolution fees
- Every AI feature is on the cheapest plan
- 30-day free trial with no card
Cons
- Starter is limited to 2 operators
- Fewer integrations and actions than larger platforms
Rank 9
SupportGPT
A simple platform for building AI support agents trained on your own sources and deployed on your site.
supportgpt.app7.9
out of 10
Best for: Indie makers and small teams that want a straightforward AI support bot with a free plan.
SupportGPT does the core job of an AI support agent without much ceremony. You add sources, let it crawl your website, set the tone and test questions in a playground before you embed the agent. It works with OpenAI, Gemini, Anthropic and other models, supports more than 90 languages and includes smart actions, human handoff and guardrails that keep answers tied to approved sources.
The pricing is easy to read: free with 50 message credits, Hobby at $40 a month for 4,000 credits and one agent, Standard at $150 for 12,000 credits with three seats and two agents, and Pro at $500. Hobby's credit allowance is generous next to Chatbase at the same price, but team seats only arrive on Standard, and the product has fewer channel options than AgentStack or Can I Help. For a solo founder adding AI help to a product site, it is a good low-risk option.
Standout feature
Hobby's 4,000 monthly credits for $40 is one of the better credit allowances at that price.
Use cases
Solo founders
Crawl a product site and deploy a bot
Outcome: Answers to common questions in minutes
Small teams
Test answers in the playground
Outcome: Fewer wrong answers at launch
Global products
Serve users in their own language
Outcome: Support in 90+ languages
Key features
- Agents trained on your sources with website crawling
- Supports OpenAI, Gemini, Anthropic and other models
- Smart actions and human handoff
- Guardrails that keep answers grounded in approved sources
- Answers in more than 90 languages
Pros
- Free plan with no card
- Playground to test answers before going live
- Hobby includes 4,000 credits, more than many rivals at the same price
Cons
- Free plan has only 50 message credits
- Team seats start on the $150 Standard plan
Rank 10
Yellow.ai
An enterprise agentic AI platform for customer and employee service across chat, voice, email and SMS.
yellow.ai7.9
out of 10
Best for: Large companies automating support across many channels and languages.
Yellow.ai is an enterprise platform for automating service conversations across chat, voice, email and SMS, and it also targets internal employee support. It lets you pick from more than 15 large language models for different tasks, build agents in an omnichannel builder, and use VoiceX for natural voice calls. Enterprise plans include unlimited agents, 35+ channels, 150+ integrations, custom dashboards and SOC 2, GDPR and ISO compliance.
The free tier is more useful than it first looks: one agent with 500 resolutions a month included, then $0.99 per resolution, though most advanced features are marked limited. Everything beyond that needs a sales conversation, and building multi-channel flows takes real configuration work. Small teams will move faster with Tidio or Chatbase, but a large company that needs voice and messaging automation in many languages should put Yellow.ai on its shortlist.
Standout feature
It covers voice, chat, email and SMS with a choice of 15+ language models, and the free tier includes 500 resolutions a month.
Use cases
Enterprise support
Automate voice and chat in many languages
Outcome: One platform across channels
HR and IT teams
Answer employee questions with AI agents
Outcome: Fewer internal tickets
CX leaders
Pilot on the free tier
Outcome: 500 free resolutions a month
Key features
- Omnichannel agents for chat, voice, email and SMS
- VoiceX natural voice AI and intelligent email agents
- Choice of 15+ large language models per task
- Agentic discovery and AI copilot for testing and optimization
- 150+ out-of-box integrations on Enterprise
Pros
- Covers voice, chat, email and SMS from one platform
- Free tier includes 500 resolutions a month
- Enterprise compliance including SOC 2, GDPR and ISO
Cons
- Free tier limits most features
- Enterprise plan requires a sales conversation
- More configuration than small-team tools
Frequently asked questions
+What is an AI customer support agent?
It is software that answers customer questions on its own using your help center, docs and store data, and hands the conversation to a person when it cannot help. Newer agents can also take actions such as looking up an order or updating a cart.
+How much does an AI support agent cost?
Per-resolution tools charge about $0.99 per resolved conversation, as Intercom Fin and Yellow.ai do. Credit-based tools such as Chatbase, SupportGPT and AgentStack start at $30 to $40 a month, and flat-priced tools like SignalZen start at $29 a month with unlimited chats.
+Is there a free AI customer support agent?
Tidio, Mava, SupportGPT, AgentStack and Can I Help all have free plans, and Yellow.ai's free tier includes 500 resolutions a month. Free plans are capped, often at 30 to 100 conversations or a small number of message credits.
+Can an AI agent replace my support team?
Not fully. AI agents handle repetitive questions well, but complex, emotional or account-specific issues still need people. Pick a tool with clean human handoff so customers are not stuck with the bot.
+Which AI support agent works with Discord or Telegram?
Mava is built for community support in Discord, Telegram and Slack, alongside email and web chat. Most other tools on this list focus on website chat and email.
+Can I add an AI agent to the help desk I already use?
Yes, Intercom Fin can run alongside other help desks such as Salesforce, and Zendesk includes AI agents in its own plans. Builder tools like Chatbase and SupportGPT can also be embedded next to an existing inbox.
