ChatFast
AI support agent that answers only from your website and docs with cited sources, captures leads and hands off to humans.
What it does
ChatFast builds AI support agents that answer questions using only your website content and uploaded documents. Answers are grounded and cited, the agent refuses to guess when sources lack an answer, and every chat can capture leads, summarize, or hand off to a human.
