Kompas

Kompas gathers documents, highlights, voice notes, and web pages into one place, marks them as yours, and lets you think through topics in sessions where Kompas pulls in past notes, decisions, and reading to ask questions back. Each session leaves connected traces in a graph, and sessions can be moved into a draft with past work surfaced when helpful. It is offered as a free local-first desktop app for macOS and Windows that works with your own AI keys or local models via Ollama, and as a paid Pro tier with cross-device sync and built-in managed AI. The page states that data is never used to train models and that the desktop app is open source under the MIT license.
