Why StashSync.app?

Works Offline, Always

Every note, bookmark, and file is stored locally using IndexedDB. Read, write, and search your entire workspace without a single byte of internet.

Sync Without Conflicts

CRDT-powered sync merges changes from all your devices cleanly — no overwritten edits, no version hell. Reconnects automatically when you come back online.

Open Formats, No Lock-in

Export notes as Markdown, bookmarks as Netscape HTML, or everything as JSON. No proprietary format, no export tax. Your data stays yours — forever.

A Rich Editor for Real Work

Slash commands, math equations, wiki links, code blocks with syntax highlighting, callout boxes, tables, and toggles — in a clean, distraction-free editor.

Notes, Bookmarks & Files Together

One workspace for everything you capture. Write long-form notes, save web pages with OG previews, and store files — all organized in a single place.

Organize Without Thinking

Stashes, Tags, pin, bulk actions, and a ⌘K command palette. Group anything, find everything, and reorganize across all item types in seconds.
