Reor

Key Features

Local-First Architecture

All AI models, embeddings, and vector storage run entirely on your machine. No cloud dependencies, no data leaving your device.

LLM-Powered Q&A

Ask questions in plain language and get answers grounded in your personal notes. Uses retrieval-augmented generation (RAG) to provide contextually accurate responses.

Automatic Linking of Ideas

Reor connects related notes automatically based on vector similarity. No more manual linking or tagging to find related thoughts.

Semantic Search

Find notes based on meaning, not exact words. Reor understands the intent behind your queries, even if you don’t remember the phrasing.

Obsidian-Like WYSIWYG Markdown Editor

Write in clean, familiar Markdown with a what-you-see-is-what-you-get interface designed for structured and free-form thinking.

Writing Assistant

Generate drafts, continue thoughts, or ask for writing suggestions—all powered by a local AI assistant tuned to your personal notes.

Augmented Thinking Interface

Toggle a sidebar to view contextually relevant notes as you write, helping you make unexpected but meaningful connections in real time.

Reor: Local-First AI Note-Taking for High-Entropy Thinkers

What if your notes could think with you?

Reor is a private, local-first AI personal knowledge management app designed for people whose ideas resist easy structure—high-entropy thinkers. It doesn’t just store what you write; it understands it, connects it, and helps you rediscover it.

The End of Manual Linking

In traditional note-taking systems, keeping track of relationships between ideas is a job in itself. Reor removes that overhead. As you write, every note is automatically embedded into a local vector database. Connections between related notes are made on the fly, using vector similarity—no need to manually create links or tags.

This means that a note you wrote weeks ago might suddenly reappear as a helpful reference in your current thinking, without you ever searching for it. The app becomes a quiet co-thinker, always ready to bring relevant context to the surface.

Chat with Your Second Brain

Reor turns your notes into an active dialogue. Thanks to a local LLM (powered by Ollama, Transformers.js, and LanceDB), you can ask questions in natural language and get answers drawn directly from your personal corpus.

The system uses Retrieval-Augmented Generation (RAG) under the hood: it retrieves relevant chunks from your notes and feeds them into the LLM for more accurate and grounded responses. It’s like talking to a version of yourself who’s read everything you’ve ever written—and remembers it better than you do.

Search That Understands Meaning

Sometimes you don’t remember the exact words you used—but you remember the idea. Reor’s semantic search lets you find notes based on meaning, not just phrasing. This eliminates friction between thinking and retrieving, allowing your memory to work more like your mind does—conceptually, contextually.

Markdown as the Language of Thought

The writing experience in Reor is familiar and frictionless. It features a WYSIWYG Markdown editor in the spirit of Obsidian—so you can structure your notes exactly how you like, while benefiting from the power of AI under the hood.

Your Data Stays Yours

Everything runs locally: the LLM, the embedding models, and the vector database. There are no cloud calls, no uploading your thoughts to a remote server. Reor aligns with a key principle: that tools for thought should respect your privacy and sovereignty by default.

AI-Augmented Thinking

Reor is more than just a note-taking tool. In a way, it’s a collaborative RAG system—with two generators: the human and the LLM. When you're writing, the sidebar surfaces related notes automatically. When you're searching or asking questions, the AI finds and interprets relevant parts of your corpus.

This dual augmentation—during both input and retrieval—creates a powerful feedback loop between you and your ideas. It's a way of thinking with your notes, not just storing them.

Reor is built on the belief that tools for thought should be private, powerful, and personal. If you're someone whose thinking doesn't follow a straight line, you might find in Reor a partner that helps make sense of the chaos—quietly, locally, and intelligently.
