How to choose an AI customer service chatbot
Start from where your support already happens. If you run a help desk, its own AI agent is usually the simplest place to start. If you only need answers on your website, a chatbot builder is often simpler. Most AI agents now charge per resolution or per conversation on top of the plan, so estimate your monthly volume before you compare prices.
You run a help desk with a support team
Zendesk includes AI agents and a few automated resolutions per agent on every plan, with extra resolutions at $1.50 to $2.00 each. Freshdesk starts at the same $19 per agent, is free for 2 agents for 6 months and includes AI Agent sessions to start. Fin works on Intercom's own help desk or on top of Zendesk and Salesforce, so you can add it without moving your team. If you already sell with HubSpot, its Customer Agent keeps support next to your CRM data, on the Professional plan or higher.
You sell online
Gorgias is a help desk built for ecommerce brands, priced by tickets rather than by agent, with its AI Agent on every plan. Tidio has a free plan, live chat and add-to-cart inside the chat. Chatbase has connected natively to Shopify since February 2026. Our Chatbase vs Tidio comparison puts the two side by side.
You want answers from your own documents
CustomGPT.ai answers from your own documents and cites its sources, with 10 agents on the entry plan. Chatbase trains an agent on your content, including past Zendesk or Salesforce tickets, and the same agent can reply by chat, email or phone.
You want to build a custom agent
Voiceflow is an AI agent platform for building chat and voice agents that handle jobs such as order tracking, returns and bookings. It suits teams with someone to design and maintain the agent, and its prices are by quote. Ada suits large companies that want one AI agent across chat, email and voice, bought through a sales process.
Intercom is now Fin, and Forethought is part of Zendesk
In May 2026 the company behind Intercom renamed itself Fin, after its AI agent, and kept Intercom as the name of its help desk. Forethought, which was listed on this page before, joined Zendesk in March 2026 and is now sold as Forethought AI agents by Zendesk. Older guides may still use the previous names.

AI customer service chatbots FAQ
What is the best AI customer service chatbot in 2026?
Fin is the best AI customer service chatbot in our 2026 rankings, at 4.8 out of 5. It suits support teams that want an AI agent on Intercom or on the help desk they already use. Zendesk follows at 4.7 for teams that want AI inside a full help desk. On a smaller budget, Tidio has a free plan and Freshdesk is our help desk pick. The right choice depends on your volume and where your support already lives.
Is there a free AI chatbot for customer service?
Yes, Tidio has a free plan with 50 conversations, plus 50 one-time free conversations with its Lyro AI agent. Chatbase lists a free plan with 50 message credits a month, and Voiceflow gives one-time free credits for building and testing. Freshdesk is free for up to 2 agents for 6 months. HubSpot's free plan covers 2 users but not its AI Customer Agent, and Fin, Zendesk and CustomGPT.ai offer trials instead.
How much does an AI customer support agent cost?
Fin starts at $0.99 per outcome, and most AI customer support agents now charge in a similar way, per resolution on top of a plan. HubSpot's Customer Agent uses $0.50 of credits per resolved conversation on the Professional and Enterprise plans. Zendesk charges $1.50 to $2.00 for each automated resolution beyond those included, and Gorgias about $0.90 per resolved interaction on annual plans. Tidio sells its Lyro AI agent from $32.50 a month, billed yearly, for 50 conversations.
Can an AI chatbot work with my existing help desk?
Yes, Fin can run on top of Zendesk or Salesforce without moving your team off it, with a 50-outcome monthly minimum. CustomGPT.ai has an app in the Zendesk marketplace and can use Freshdesk content as a knowledge source. Chatbase learns from past Zendesk and Salesforce tickets, and Tidio's Lyro Connect adds its AI agent to another help desk on the Plus and Premium plans.
What is the difference between an AI chatbot and an AI agent?
An AI agent, such as one built on Voiceflow, goes beyond answering questions: it can take actions through connected systems, such as tracking an order or booking an appointment. A classic chatbot follows set flows or answers from a fixed set of articles. Many tools on this page now do both, and they usually bill the agent's work per resolution or per conversation.
Which AI chatbot is best for a Shopify store?
Gorgias and Tidio are our top picks for Shopify stores on this page. Gorgias is a help desk built for ecommerce, priced by tickets, with its AI Agent on every plan and 4.3 stars on the Shopify App Store. Tidio has a free plan, add-to-cart inside the chat and 4.8 stars from 1,354 Shopify App Store reviews. Chatbase also connects natively to Shopify.

- What is listed
- AI customer service chatbots and AI support agents: help desks with AI built in, chatbot builders that answer from your own content, and platforms for building custom agents. Fin, Zendesk, Ada and Gorgias don't have a full review on this site yet, so they show no Reviewed tag.
- Our picks
- Best overall is always the highest-rated tool on this page. Each other pick is our choice for one kind of reader. The strengths and limits listed for the picks come from each tool's review where we have one, the vendor's own pages and recent independent reviews.
- Ratings
- Each rating is our overall score for the tool on a 5-point scale, and the list is ordered by it. We rechecked every rating on 16 October 2026 against its latest releases, prices and recent independent reviews. A score rates the whole product, not only its AI agent. Read how we test and rate tools.
- Prices
- The lowest paid plan, read from each vendor's pricing page on 16 October 2026 (HubSpot on 15 October), on annual billing where the vendor offers it. Gorgias's Starter plan and HubSpot's Starter figure are monthly prices. Ada and Voiceflow don't publish prices. Most AI agents add a charge per resolution or conversation on top, covered in the FAQ. On 16 October HubSpot showed a new-customer discount on Service Hub Starter; we list the regular price.
- Update log
- 16 October 2026: new layout, ten tools instead of twelve and four picks explained in detail. Ratings rechecked (Freshdesk 4.5 to 4.4; HubSpot now shows our 4.6, up from 4.3 on the old page) and every price and free plan read again. Voiceflow added; Forethought (now part of Zendesk), Kustomer and Quidget removed.
