What Chatbase is and who the AI agent is for
Chatbase is an AI platform for building agents that answer customer questions using your own content. It started as a simple “chat with your website or PDF” chatbot tool and now positions itself as an AI agent for customer experience, covering support, sales and product guidance across chat, email and voice.
You connect your data sources (website, help centre, documents and so on), write instructions for the agent, set guardrails and then deploy it on your site or in channels such as WhatsApp, Slack, Instagram and Messenger. Chatbase says no code is needed to get an agent running.
How Chatbase works
The vendor describes four stages. You build the agent by connecting data and setting its role and guardrails. You test it against real customer scenarios before going live, checking that each answer is accurate and on brand. You deploy it to your channels. Then you optimise Chatbase by tracking resolution rates, reviewing conversations and escalations, and refining the instructions. In practice that last step is where most of the work sits with any AI support bot: someone on your team needs to read through conversations regularly and fix the gaps in your content.
It suits small and mid-sized businesses, SaaS companies and ecommerce shops that want an AI support agent without a big help desk project. Large support teams already deep in Intercom or Zendesk might prefer the AI agent built into their help desk, although Chatbase does connect to both on its higher plans.
Key Chatbase features for customer support conversations
Train the agent on your own data sources
Each Chatbase agent is trained on content you supply, so it can answer from your own policies and product information rather than generic knowledge. On the Business plan, Chatbase can suggest new sources and use past support tickets as a source. Auto-resync, which keeps the agent up to date when your content changes, is included from the Basic plan. Training content is capped at 40 MB per agent as standard on every self serve plan, with extra storage sold separately. The vendor says it is not used to train shared models.
AI Actions and procedures
Beyond answering questions, a Chatbase agent can take actions such as looking up an order, fetching invoices or showing available booking slots. The pricing page lists 5 AI Actions per agent on Hobby, 8 on Basic and 12 on Business, plus a set number of “procedures” (step by step flows, for example handling a return). This is what separates Chatbase from a basic FAQ bot, because the agent can handle a task rather than only answer a question, but you need to plan the actions you want, as the limits are fairly low.
Model choice and training data
Chatbase lets you pick the underlying language model, which is useful if you want to balance answer quality against credit use. Every plan includes advanced models from OpenAI, Anthropic, Google Gemini, DeepSeek, Mistral, MoonshotAI and Z.ai, according to the plan comparison. The home page demo shows Claude Sonnet 4.6 as the selected model.
Channels, helpdesk, voice and human handover
The Hobby plan includes Shopify, Slack, WhatsApp, Messenger, Instagram, Calendly and WordPress integrations. Basic adds the Chatbase helpdesk inbox (so a person can pick up a conversation the agent cannot finish), voice and telephony (10 concurrent calls), outbound campaigns, API access and integrations with Stripe, Zendesk, Salesforce, Intercom, HubSpot, Zoho Desk, Freshdesk, Help Scout, Gorgias, Zapier, Twilio and others. Human handover to a ticket or help desk is the main reason most customer support teams will need Basic rather than Hobby, because the AI will not handle every conversation on its own.
Analytics and security
All Chatbase plans include basic analytics, and Business adds advanced analytics. On security, Chatbase lists GDPR compliance, a SOC 2 Type II audit and HIPAA eligibility (HIPAA is listed under Enterprise), and states that your data is only accessible to your agent and not used to train models.
Chatbase pricing and message credits
Chatbase pricing is based on “message credits” per month, with a 20% discount for yearly billing. These are the prices on the pricing page on 27 October 2026:
| Plan | Monthly billing | Billed yearly | Message credits per month | Seats |
|---|---|---|---|---|
| Hobby | $40 | $32 a month | 700 | 2 |
| Basic | $150 | $120 a month | 4,000 | 3 |
| Business | $500 | $400 a month | 15,000 | 5 |
| Enterprise | Custom | Custom | Custom | |
Each self serve Chatbase plan includes one agent. Add-ons are priced separately: auto-recharge credits at $40 per 1,000 message credits, extra agents at $300 per agent per year, extra storage at $300 per 10 MB per year and removal of the “Powered by Chatbase” branding at $1,188 a year. The pricing page did not show a free plan when I checked. Enterprise adds SSO, audit logs, custom roles, white-labelling, SLAs and a success manager.
Chatbase pros and cons
The strengths of Chatbase are clear from the vendor’s own material: quick setup, a wide choice of models on every plan, and a long list of help desk and messaging integrations. Public Trustpilot reviews often praise the Chatbase support team for quick, helpful answers, with several customers naming individual staff.
The weaknesses of Chatbase are mostly about cost and limits:
- Pricing has moved a long way up from the early days. One long-term customer on Trustpilot says usage costs tripled and features were removed from older plans, which is worth reading before you commit to a yearly plan.
- 700 message credits on Hobby will not go far for a busy site with lots of customer conversations, and help desk handover, API access and voice all need the $150 a month Basic plan.
- Only one Chatbase agent is included per plan. A second brand or language agent costs $300 a year extra.
- Removing the “Powered by Chatbase” branding is a costly add-on at $1,188 a year on self serve plans.
- The 40 MB training content cap is fine for most help centres but could be tight for large document libraries.
Chatbase alternatives and other support tools
- Intercom Fin is the obvious choice if your team already runs support in Intercom and wants the AI agent inside the same help desk.
- Tidio combines live chat and an AI agent at a lower entry price, aimed at small ecommerce shops that want a human and bot in the same conversation.
- CustomGPT.ai focuses on accurate answers from your own documents and suits knowledge-heavy use cases.
Verdict: is Chatbase worth it?
Overall Chatbase is a capable, well supported tool for putting an AI customer support agent on your website and messaging channels, with good model choice, a long integration list and the features most teams need to hand difficult conversations to a person. I would pick Chatbase if you want an agent live quickly and can justify the Basic plan, as that is where help desk handover, actions and API access come together. If you are price sensitive, need several agents, or already pay for a help desk with its own AI agent, I would compare it carefully before committing to a yearly plan.
