Sync status is always visible.
Sync health lives in the status bar. A cycle that fails says so and retries.

Your notes follow you to your iPhone and into your AI chats.
Valutorio Sync keeps your Mac and iPhone current in the background, encrypted, with nothing to set up. It also gives ChatGPT, Claude, and whatever assistant you use a private way to read and write your notes, even when your Mac is off.
one square per day of syncing; none left a conflict marker in a note
Why not the app you use now?
The popular knowledge-base apps run on Electron, and it shows: on large vaults, startup can take 25 seconds. The most-used sync plugin writes conflict markers into your notes when a merge fails and leaves you to fix them on the command line. Some users lost notes to silent overwrites; others learned weeks late that sync had quietly stopped.
Valutorio keeps the ideas and replaces the engine. Parsing, search, the link graph, and sync are Rust; the interface is Swift; no JavaScript sits between you and your notes.

Sync that never shows you a conflict marker.
Turn on Valutorio Sync and your Mac and iPhone stay current in the background: encrypted, automatic, nothing to set up. Edit on two machines, go offline for a week, come back; the engine merges what it can and keeps both versions when it can't. Zero conflict markers ever touch your notes.
It repairs itself.
Quit mid-sync, lose power, delete the app's state: the next cycle repairs it. Verified 65 out of 65 times in kill-mid-sync testing.
Under a second after the first sync.
First full sync of 2,000 files takes about 30 seconds; every cycle after is under a second. Typing never stutters.
A second brain for every AI you use.
Ask ChatGPT or Claude a question from your phone and it can search your notes, read them, and write the answer back, even while your Mac is asleep at home. Your synced notes have a private address in the cloud; you hold the key and can change it anytime. There is nothing to install and no computer to leave running.
Under the hood: a hosted MCP endpoint (Model Context Protocol, the open standard AI assistants use to reach tools), with a token you can rotate or revoke in the app.

A folder of markdown files. That's the whole format.
Point Valutorio at a folder of plain .md files: nothing is imported, nothing is converted. Sync is an optional subscription; without it the app still does everything, offline, forever. Delete the app tomorrow and you lose nothing.
