Chat.sh

Chat.sh is an AI-powered help center search engine that reads user questions and provides direct answers with source pages.

Chat.sh is an AI-powered help center that reads user questions and answers them directly, citing the specific pages it used instead of just returning a list of links. It is designed for businesses and teams that want to host a help center on their own domain or inside an existing folder like /guide or /help. Users can upload articles, web links, files, and text or markdown documents into a single knowledge base to power the help center, a chat widget, and markdown exports for external AI tools like ChatGPT and Claude. The platform features clean URLs based on article titles, custom accent colors, and article previews for messaging apps. It offers a free tier as well as a lifetime purchase option with no recurring subscription fees.
