ChatFast builds customer-facing AI agents that answer from a knowledge base, collect structured information, and prepare handoffs.
About ChatFast
ChatFast builds customer-facing AI agents for business websites. An agent is connected to a knowledge base drawn from a website, help center, PDFs and files (including scanned documents), and answers customer questions only from those sources, saying so when an answer is not present. Agents can also collect contact details and form fields in the chat, then route the result by email, an API call or a webhook, and pass unresolved conversations to a team inbox with the full transcript. A playground lets teams test real support and sales questions before launch, and an insights view shows conversations, captured contacts and questions answered with low confidence. Installation is described as one snippet on the site. Pricing is not stated; a 14-day free trial without a credit card is advertised, and unlimited agents are said to be included on every paid plan.
