Obsidian

Obsidian
Obsidian is a note-taking app that works with plain text files stored directly on your device. You can write notes, link them together, and see how your ideas connect through a visual graph. Unlike cloud-based tools, everything stays private on your computer.

Notion

Notion
Notion is a versatile all-in-one workspace that functions like a set of digital building blocks. Think of it as a combination of Google Docs, Trello, Airtable, and Evernote all rolled into one seamless platform. Every page in Notion is built using 'blocks' - individual pieces of content like text, images, databases, or embedded files that you can arrange however you want.
