Make Your 2nd Brain Foss

I recently finished reading a book by Tiago Forte - “Building a Second Brain”. I instantly noticed the complete disregard for user privacy and security when it came to choosing the right note taking app. So here I will share some better options that actually respect you.

NOTE: some of the apps are mentioned on the official website of the book, but there is no accent on them being FOSS.

Note taking apps

  • Joplin - Has loads of great integrations with different systems. Has support of types of devices.

  • Affine - Integrates AI features, has an interactive board, but not phone app (yet)

  • Zettlr - arguably the most professional tool in this list. It Uses regular markdown, making it extremely versitile. Sadly doesnt have a phone app

  • Notesnook - A modern and advanced knowledge collection tool. Is in very active development. New versions are made multiple times a month. Marketed as a FOSS evernote alternative

  • Quillpad - Very simple and straight forward phone note taking app.

  • logseq - Arguably the best app for the 2nd brain setup. Uses a slightly strange version of markdown, but that allows for extremely productive and efficient workflows and great project planning, thanks to an infinite canvas board that is fully integrated with the rest of the notes.

  • Markor - my 2ndBrain app of choice (on phone). Its a very minimal, and to the point app that doesnt reinvent the wheel in any way.

Todo apps

  • Tasks.org - Feels like a modern and polished todo tool with many built in sync options (even the proprietary ones)

  • ntodotxt - Personal todo app of choice. uses the todo.txt format

  • Sleek - another app that uses todo.txt format


This list is not complete. If you have any other software to add, or some remarks about software already present, feel free to contact me. on matrix: @fedorvin:matrix.org
