What is Chat9?

Chat9 is an AI-powered support bot platform for B2B SaaS companies.

You upload your product documentation, and Chat9 creates a smart chat widget that answers your customers' questions automatically — 24/7, in any language.

How it works

1. Add your knowledge — upload PDF, Markdown, and Swagger/OpenAPI files (.json, .yaml, .yml), or index a documentation website URL. OpenAPI files and structured OpenAPI URLs are indexed as API operations, not as raw JSON/YAML text.
2. Get a chat widget — a JavaScript snippet you embed on your website in 2 lines of code.
3. Your customers get instant answers — the bot answers based on your documentation only. No hallucinations about products you don't sell.

Key features

• RAG pipeline — answers come directly from your documentation, not from generic AI knowledge.
• Controlled clarification — if one critical detail is missing, Chat9 can ask one specific follow-up question (at most one per conversation) instead of guessing or bouncing the whole problem back to the user.
• Hybrid retrieval + reliability signals — Chat9 combines vector search with lexical retrieval and keeps overlap / contradiction evidence for debugging.
• Gap Analyzer — turns weak coverage and repeated customer questions into a backlog your team can review from the dashboard.
• Full conversation logs — see every question your customers ask in the dashboard.
• Thumbs-up / thumbs-down feedback — mark good and bad answers, review and improve over time.
• Your OpenAI key — you connect your own OpenAI API key. You control AI costs directly.
• Multi-language — ask in English, get answers from Russian docs. Responds in the user's language automatically.

Who is it for?

Chat9 is designed for SaaS companies, API providers, and technical products that have documentation and want to reduce repetitive support tickets.
