Built for real work

Edit here. Edit there.
Meet in the middle.

Syncdian uses three-way merging for text across devices. Non-overlapping edits come together automatically. Overlapping changes preserve both sides with clear markers. Binary conflicts get a separate copy.

The unglamorous details

Handled by the system.
Not by you.

01

Server-managed encryption

Vault keys are encrypted with a master key. Files and paths are stored as ciphertext in R2.

02

Private note links by design

Public-note encryption keys stay in the URL fragment. The server stores only the encrypted note.

03

Safe on every filesystem

Filenames that work on macOS but not Android receive reversible, device-local aliases.

04

Clear storage limits

See exactly how much of your 100 MB you are using. No hidden sync count or device limit.

Good to know

A few honest answers.

Is Syncdian end-to-end encrypted?+

No. Syncdian uses server-managed encryption for vaults: keys are encrypted with a master key and files are stored as ciphertext. Public notes use a browser-generated key in the URL fragment. Collaboration rooms also write encrypted snapshots back to the owner’s vault.

Do guests need a Syncdian or GitHub account?+

No. Anyone with the complete collaboration link can edit the shared Excalidraw drawing. The owner can turn off sharing at any time, immediately disconnecting guests and revoking the link.

Do my vaults need the same name on every device?+

No. Sync follows the cloud vault, not the local folder name. You can use “Work” on your Mac and “Work notes” on Android.

What happens when two devices edit the same note?+

Text changes use a three-way merge. Excalidraw collaboration uses Yjs for real-time element synchronization, presence, and reconnect recovery.
