Kompas

Kompas is a desktop thinking and writing app that gathers a person's reading, conversations and half formed ideas in one place, connects them, and turns them into finished work. Users capture documents, highlights, voice notes and web pages, then start a session on a topic and think it through with an AI that pulls in their past notes, decisions and reading to ask better questions back. Each session leaves connected traces that build into a graph, and that graph becomes the raw material for writing. It is aimed at writers, researchers and anyone who wants their ideas to compound instead of being lost after each chat with a model. The free desktop app for macOS and Windows is local first and open source under the MIT license. Ideas stay on the user's device, and the user supplies their own OpenAI or Anthropic key, a Claude Code or Codex subscription, or local models through Ollama. The vendor states that user content is never sold and never used to train models. Pricing is published in US dollars. The desktop app is free. Pro Sync, for users who bring their own keys or local models, costs $3 per month or $30 per year and adds cross device sync between desktops. Pro Full, which adds managed frontier AI with included usage, costs $38 per month, or $33 per month billed annually. Pro Cloud offers a 7 day free trial with no credit card required.
