Chatbase

Chatbase lets you create custom AI chat agents trained on your website, documents and help centre, then embed them for customer support, lead capture and internal Q&A, popular with SaaS teams and small businesses. Setup is no-code: point it at a URL or upload files, tune the persona, and add actions such as ticket creation or handoff to a human. A free plan covers testing, with paid tiers for more messages and integrations.
