Sutsumu is a personal archive for texts, notes and documents you want to keep with care. A simple tool, executed with an editor's eye.
WHAT YOU CAN DO
· Create Markdown documents with "Edit" and "Read" modes.
· Organize them into collections with the color and icon you choose.
· Tag, categorize, and attach images or files.
· Three layers of backup — export, restore, and history.
· Sync between your devices with your own account.
· Or use Local Mode, no account or cloud, from day one.
REAL PRIVACY
· No analytics, no behavior tracking.
· Crash reports are opt-in: off by default.
· The content of your documents never leaves your device without your say.
· Open source for the critical components; auditable.
EDITORIAL AESTHETIC
The app evokes a printed magazine: serif typography, section headers, paper warmth. We don't want to add more noise to your day — but give a worthy place to what you write.
SUTSUMU PREMIUM
An optional one-time purchase unlocks the AI Archivist to help organize documents with suggestions you can always review. All existing features remain free. No subscription.
LANGUAGES
Catalan (base language), Spanish, English, French, and Italian.
· · ·
Sutsumu is for you if you value your texts more than volume, care more than speed, and calm more than engagement metrics.
