v1.0 — now in beta
Your notes,
on a blockchain you own.
AtomicNote turns every note into a cryptographically signed block on a personal chain that lives on your device. Upgrade to Premium to verify them on our master chain and share tamper-evident proofs.
Immutable by design
Every note becomes a block. Edits create a new block — the original stays on the chain, signed and timestamped, forever.
Yours alone
The free tier never sends your notes off your device. The local chain is entirely on-device, powered by a Rust library.
Provable
Premium pushes a hash of each note onto our master chain. Share a link — anyone can verify the note existed exactly as written.
