Reor
Local AI note-taking app for macOS, Windows and Linux, with Ollama support and note-based Q&A. Open source under AGPL-3.0; archived and unmaintained.
Reor is a local AI note-taking app for people who want to search their own writing, find connections between ideas and ask questions about their notes. The project is archived and no longer maintained. It runs on macOS, Windows and Linux, and it's open source under AGPL-3.0.
Its main distinction is how it brings related material into the writing process. While you edit a note, a sidebar can show other notes with similar content. Those connections appear automatically, so you can revisit an idea without having linked the notes yourself. Semantic search also finds notes by meaning rather than relying only on matching words.
The question-and-answer feature retrieves relevant passages from your collection and gives them to an LLM as context for its response. This makes your own notes the material for the conversation. The editor supports Markdown, and Reor keeps notes in a local folder. Existing Markdown collections can serve as its library, though frontmatter may not parse correctly.
Reor uses Ollama for local LLMs, with Transformers.js and LanceDB supporting local embeddings and retrieval. You can download and run models from within the app. Notes and their search data stay on your machine when you use the local setup.
You can also connect to an OpenAI-compatible API, including Oobabooga or OpenAI. A local backend keeps model processing on your hardware; choosing a cloud service sends the question and retrieved note context to that service.
