Chatbase

Chatbase lets anyone train a chatbot on their own documents, website, or Notion pages with no code, then embed it on a site or connect it to Slack and WhatsApp. Businesses use it to replace static FAQ pages with something conversational, and it was one of the fastest-growing AI SaaS products of 2023 — reaching $1M ARR within months of launching, back when that milestone was still a novelty rather than expected.
