What it does
Tangent is a desktop note-writing and personal knowledge management app that stores notes as local Markdown files. It uses wiki links, sliding panels, and a branching map to help writers follow connections between notes; custom queries, focus mode, and card or feed views add ways to work with a growing collection. The official site describes Tangent as free for Mac, Windows, and Linux.
Follow a thread of thought instead of forcing an outline
Tangent is designed for notes that connect gradually. Write a page, add a [[wiki link]] when another idea comes to mind, and use the sliding panels or branching map to follow the trail of navigation. The official project page also lists focus mode, customizable note views, and a query language for searching linked material. Notes remain local Markdown files that can be read or edited outside Tangent.
The current roadmap says the project is in active development; the GitHub commit history shows work through 2026-10-20. Its roadmap lists iOS/Android support and collaborative writing as later plans rather than current features. Tangent is free to download, but no installation, note migration, or export flow was tested.
Strengths
- Wiki links and a branching map support non-linear exploration of a personal knowledge base.
- Notes are local Markdown files that remain readable outside the app.
- The official site describes a free desktop app for Mac, Windows, and Linux.
Watch out for
- The roadmap lists mobile apps and collaborative writing as future work, not current capabilities.
- Its navigation model is designed for exploratory linked notes rather than a simple chronological notebook.
Best for
- Writers who want to follow associative links between local Markdown notes
- Building a personal knowledge graph without moving notes into a hosted database
