Editorial interest 84/100 Selection signal · not a rating of the site

An offline-first notes app for fast capture, live dictation, daily pages, and importing Notion or Obsidian vaults.

Landing page captured for the 2026-09-02 issue.

Field notes

Sumibako centers its workflow on immediate capture rather than workspace setup. The homepage describes a Ctrl-Alt-C overlay, browser-based dictation, offline edits that queue for synchronization, and phone share-sheet or shortcut capture. Its migration path accepts Notion Markdown exports and Obsidian vault zips while preserving nesting, but explicitly excludes Notion databases and images; the free tier is limited to 50 documents and Pro is listed at $2 per month.
