Trilium Notes is a free, open‑source, cross‑platform hierarchical note‑taking application built with Electron. It lets you build a personal knowledge base that can be used locally or synchronized via a self‑hosted server.

Use cases

• Organize personal notes in a hierarchical structure without folders.
• Synchronize notes across multiple devices using a self‑hosted server or Docker deployment.
• Search full‑text across notes, PDFs and images with OCR support.
• Create and reuse note templates for consistent data entry.
• Publish a subtree of notes as a public read‑only website.
• Clip web pages or screenshots directly into the note tree via a browser extension.

When to choose

• You need an offline‑first, local‑first note‑taking tool with powerful hierarchical organization.
• You want to self‑host synchronization and keep full control over your data.
• You require advanced search, OCR, and template capabilities for a personal knowledge base.

When to avoid

• You need real‑time collaborative editing with multiple users simultaneously.
• You prefer a lightweight, single‑file note app with minimal dependencies.
• You are looking for a mobile‑only solution without a desktop component.
