Sync conflicts are where note apps lose trust. Two devices edit the same paragraph offline — what survives, and does the user ever have to think about it?

Built on a CRDT document model with a Rust core compiled to WebAssembly. Every keystroke is saved locally first; the network is treated as an optimisation, not a requirement.

Zero data-loss reports across 12k users. Saving is instant because it never waits for a server.
