reor

Reor is a desktop note-taking app that runs AI tools entirely on your own computer, with no data sent to external servers. It works on Mac, Linux, and Windows. You write notes in a markdown editor that looks similar to Obsidian, and everything is stored in a folder you choose on your filesystem.

The core idea is that your notes are not just stored but actively processed. Each note is split into chunks and turned into a numeric representation stored in a local database. This lets the app find connections between notes automatically, based on what they are actually about rather than just keywords. When you open a note, a sidebar can show you related notes pulled from your collection.

Reor also lets you ask questions about your notes in a chat-style interface. Instead of searching manually, you type a question and the AI looks through your notes to find relevant passages and uses them to form an answer. This is useful when you have a large collection and want to find what you wrote about a topic without remembering the exact file or phrase.

The AI models that power all of this run locally through Ollama. Inside the app you can download and switch between models from Ollama's library. You can also connect to other OpenAI-compatible APIs if you prefer.

Importing notes from another app means copying your markdown files into the chosen folder manually, since there are no direct integrations yet. The project is open-source under AGPL-3.0 and welcomes contributors. The name comes from the Latin word for to think.
