ChatFast lets you build AI agents that answer from your website, help center, PDFs, and Q&A docs, then embed them on any site with one snippet. Agents reason through multi-part questions, collect lead details in chat, and escalate edge cases to humans with the full transcript attached.
Most chatbots match keywords and return canned replies. ChatFast indexes your approved sources, runs answers through a playground for validation, and reports 94% accuracy compared with regular chatbots on the homepage. The platform states none of your data is used to train its models.
Support, sales, and research teams deploy ChatFast agents to resolve requests, qualify visitors, and capture contacts without rebuilding a bot for every workflow. A 14-day trial includes one agent, 1,000 credits, and 5 MB of storage with no credit card required.
