Open source alternatives to Gemini Notebook

By GitHub stars it is Khoj, with 38,125 stars and a commit on 2 Aug. Choose Khoj when you want answers grounded in your own documents without uploading them to a Google account. Next come SurfSense (16,867 stars).

Yes. The code of all 2 is public under AGPL 3.0 or Apache 2.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.

Start from the job you use Gemini Notebook for. Choose SurfSense when your sources cannot leave your machine, or you want to pick the model, including one running locally.

All 2: Khoj and SurfSense. Each tool's page says what it needs to run.

1 of the 2 we track had a commit in the last 30 days, among them SurfSense. The quietest is Khoj, last changed on 2 Aug. A recent commit shows the project is kept up, not that it will stay that way.

AGPL 3.0 (1), Apache 2.0 (1). MIT, BSD and Apache let you change and reuse the code freely. GPL and AGPL ask you to share your changes under the same licence when you give the software to others, and AGPL also counts letting people use it over a network.

The hosting. Gemini Notebook's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
