ChatFast

ChatFast improves the capabilities of chatbots by training them with diverse data, incorporating customized Q&A features, and offering meaningful insights into visitor interactions.

About ChatFast

ChatFast is a platform for building AI agents that answer customer requests, qualify leads and pass complex issues to human teams. Businesses connect a website, help center, PDFs and other files, and the agent answers from those sources and cites them. It can collect structured visitor details and reply in the customer's language. It runs on models from providers such as Claude, GPT, Gemini and Grok. Pricing is based on credits spent per customer message, with a free start. The vendor says it does not train foundation models on workspace data.
