With Notion, OneNote and Evernote I feel like my notes are held captive. I migrated all my notes from various note taking apps to Markdown, and I'm using Obsidian to manage them.
Obsidian is by far the most valuable product I interact with on a day-to-day. I've been using it since the beginning and the evolution of the community and product is so beautiful. Obsidian is quite literately my second brain until I die.
