📚 A real library browser
Browse every notebook with first-page previews — Finder-style columns, a thumbnail grid, or a details list. Choose exactly which notes and folders sync, rename outputs, pick a format per note.
🔁 Hands-off sync
The engine watches your device's library and mirrors changed notes into normal PDFs (or SVG/PNG) within a minute or two — into iCloud Drive, Dropbox, a git repo, wherever you point it. Your source library is never written to. Ever.
🪄 Drag-and-drop conversion
Drop a .goodnotes, .ntb, .sba
or 15 other note formats on the app and get editable ink out —
not a flattened picture. Per-point pressure, tilt and pen widths
survive the trip where the target format can hold them.
🔬 Reverse-engineered carefully
Every format claim is validated against the app's own exports and documented with confidence markers — the format specs are public. Fidelity is pinned by golden tests, measured in pixels, not vibes.
