Note-Taking & Knowledge Management
These go far beyond simple text files, helping you connect and organize your thoughts.
- Obsidian: A powerful and incredibly popular “second brain” tool. It stores your notes as plain text files (Markdown) in a local folder, giving you complete control. Its power comes from linking notes together, creating a web of knowledge. The core app is free for personal use, and there’s a massive plugin ecosystem.
- Joplin: A great open-source alternative to Evernote. It lets you take notes, organize them into notebooks, and sync them across your devices using various cloud services (or its own end-to-end encrypted sync service). It supports rich text, Markdown, and web clippings.
- LogSeq: An outliner-based note-taking tool that focuses on connecting your thoughts. It uses a “daily notes” page as a starting point and is excellent for tracking tasks, journaling, and building a personal knowledge base. Its structure is very appealing for users who think in bullet points.
