“Plain-text Markdown notes that live on your own device”
— Why it made the list
What is Obsidian?
Notes sit on your disk as plain text Markdown files, linked into a graph you can navigate or lay out on a canvas. Suits people who want their notes to outlive whatever app they wrote them in.
Who is it for?
Writers and researchers who want notes in open files they control rather than a vendor's database
Pricing
App free with no limits; cheapest paid tier is Sync Standard at $4 per user/month billed yearly (1 GB, one vault)
