Capture it once. Use it for years.
Cairn keeps what you read and write in one place, links it together, and brings it back when useful.
Save what you read, wherever you read it.
Browser clips, highlights from PDFs, and voice notes all land in one inbox.
Links appear as you type.
Mention an idea and it connects to every note about it, in both directions.
Old notes come back each morning.
Cairn shows the notes most related to what you opened yesterday.
Search by meaning.
Type the idea, not the exact words. Results include notes that said it differently.
Your files stay plain text.
Notes are saved as Markdown on your device, so you can read, move, or back them up with any tool.
Questions
Does Cairn work offline?
Yes. Notes you have opened stay available without a connection, and changes sync when you are back online.
Where are my notes kept?
On your device, as plain Markdown files. Cairn keeps a search index next to them.
Can I bring in notes from other apps?
Yes. Markdown folders, exported notes, and clipped web pages can all be imported.
Who can read my notes?
Only you, unless you choose to share a note.
