What it does

Crawls a web page or extracts text from PDF, DOCX and TXT, embeds it, produces a summary, and answers questions grounded in what it read — the familiar chat-with-your-document pattern, with a Colab notebook if you'd rather not install it. Everything you load reaches OpenAI, which rules out confidential material, and scraping someone's site has their terms attached. Summaries misread; check the source before acting. MIT.

Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

chatWeb FAQ

Is chatWeb free?: chatWeb itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
Do I need to install anything or write code to use chatWeb?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does chatWeb work on a phone?: No. It needs a computer.
Can I use chatWeb commercially?: The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
