Chat.sh

Chat.sh is a self-hostable help center that replaces keyword search with AI answers. Visitors ask a question, and the tool writes the answer while citing the help pages it used. It runs on your own domain, either at a subdomain or in a folder such as yoursite.com/help, and serves every help page as markdown for LLM consumption including ChatGPT, Claude, and llms.txt. It is offered as a one-time lifetime purchase rather than a subscription, with a chat messenger and support inbox listed as planned features.
