Writers and thinkers use thought organization tools to turn scattered ideas into something more coherent.

Bear is a writing and note-taking tool that runs on Apple devices. You type notes in plain text and add formatting using simple Markdown commands. This means you can make text bold, create headers, add links, or insert images without reaching for your mouse.
The app organizes notes using tags. Instead of putting notes in folders, you add hashtags anywhere in your text. These tags appear in the sidebar, and you can nest them for deeper organization. For example, you might use tags like work, personal, or ideas.
Bear keeps everything private and stored locally on your device. The free version offers solid features, while Bear Pro adds extras like cloud sync between devices, more export options, and the ability to search text inside images and PDF files.
DeepNotes is a visual note-taking application that uses an infinite canvas approach. Instead of regular pages stacked on top of each other, you get unlimited space where notes can be placed anywhere and connected freely. Each note can contain other notes inside it, creating layers of information.
The tool focuses on privacy with end-to-end encryption, meaning your notes stay protected at all times. The graph-based navigation system helps you see connections between different ideas and jump between related topics quickly. You can create notes by double-clicking on the canvas, then move them around, change colors, and organize them in containers.
DeepNotes is available as a web app and desktop application. The Basic plan is free with 50 pages, while the Pro plan removes all limits and adds team collaboration features.
