Obsidian

The free and flexible app for your private thoughts, designed to sharpen your thinking.

Overview

Obsidian is a note-taking app that stores everything on your device. You can link notes together, visualize those connections as a graph, and work offline without signing up. The core app is free with no limits attached. Paid options add sync across devices with end-to-end encryption, publishing notes as a wiki or knowledge base, and one year of version history per note. Thousands of plugins let you shape Obsidian to fit how you think.

Acts as a second brain, good for organizing thoughts. The real limitation is sharing: it's built for one person, so anything collaborative has to live elsewhere.
