Not copied from the project's own blurb. These are things we opened and verified, with the date.
- 9 Sept 2026We checked that the link to the project still resolves.
- 14 Aug 2026We read the licence text itself (LICENSE). No unusual restrictions were stated.
- 2 Sept 2026We read the project's own documentation and found no sign that development has stopped.
Where this sits among the 63 tools we list in Docs & PDF Q&A

- Commercial use confirmed as allowed52 of 63
- Requires terminal commands20 that do not →

Only 23 of the 63 meet all of the conditions above.
Counted from our own checks: every tool we list is examined against the same criteria.
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.

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.
