What it does

Document splitting, ingestion, web scraping and query workflows over your own material, usable from a browser or the terminal, and able to sit as a proxy between an Ollama client and an Ollama instance. Built on Haystack and ElasticSearch, fully containerised. It began as a tool so the author's partner could work through her book with local models instead of ChatGPT, which is a fair summary of who it suits. The linked demo host was unreachable on 2026-08-18. 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.

chipper FAQ

Is chipper free?: Yes. It runs on your own machine, so there is no usage-based cost either.
Do I need to install anything or write code to use chipper?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does chipper work on a phone?: No. It needs a computer.
Can I use chipper 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.
