Shizumu

About

Shizumu is a private space to think by writing. Open it and start the sentence: there is nothing to structure first, and nowhere to file it. You write to think, you pin what matters, and you trail what continues. The volume of writing is not the artifact; what you pin is. Nothing to structure first, nowhere to file it, and no pile waiting for you when you open the app.

Pages flow into a daily memory you can scroll back through and search by content. Pins lift the lines that matter out of the daily stream: checklists, references, anything you want close at hand. Trails group writing that belongs together (a project, a book, an ongoing thread of thought) without forcing you to design a structure first, and the first time you put a page on a trail, the pins you already kept there come back onto the page. Continuous trails are the one intentional exception: when a single thread should genuinely keep growing, you choose to trail it.

The editor is keyboard driven. Type / for a table, a chart, an outline or a block of code; type @ to reach a page, a pin or a trail. Ctrl+K opens the trail index, Ctrl+P pins from the cursor, Ctrl+F finds, and a shortcuts panel lists the rest.

Local-first by design. Everything stays on your device, in a SQLite database you can open with any compatible tool. Sync is optional and end-to-end encrypted: your writing is sealed on your device before it leaves it, the keys are derived there and never leave, and the relay holds what it cannot read. Neither can we. No account, no analytics. Your writing remains yours.

Shizumu fits the writer who keeps a daily log, the developer with one running notebook per project, the student capturing reading notes, and anyone who wants a private place to write to think without learning a tagging system first.
