## What it is
Trilium Notes is a free, open-source, cross-platform hierarchical note-taking application focused on building large personal knowledge bases. It runs as a desktop Electron app or a self-hosted server with sync, offering note trees, attributes, full-text search, encryption, and web publishing.

## Use cases
- build a personal knowledge base with hierarchical notes
- self-host a note-taking app with device sync
- organize research notes with labels and relations
- publish notes as a public read-only website
- clip web pages into my notes
- search full text across notes including OCR in images and PDFs
- keep encrypted protected notes behind a password
- access my notes offline on desktop and mobile PWA

## When to choose
- you want a local-first, self-hosted knowledge base with deep hierarchical structure
- you need cross-device sync via your own server without third-party accounts
- you want scriptable notes with templates, attributes, and revisions
- you prefer open-source (AGPL-3.0) with no account required

## When to avoid
- you want simple flat notes with minimal setup
- you need real-time collaborative editing with a team
- you prefer a hosted cloud service managed for you
- you need a mobile-native app rather than a PWA
