About

Start writing in Shizumu immediately, without creating folders, tags, or an outline first. It provides a private place to think on the page, treating the lines you pin as the lasting record rather than the total volume of your writing. Pages flow into a daily memory that you can scroll through later or search by their content.

Pins pull important lines into quick-access collections for checklists, references, and other material you want nearby. Trails gather related pages around a project, book, or continuing idea without requiring a preplanned structure; adding a page to a trail also brings back the pins already kept there. You can deliberately keep one thread growing as a continuous trail when that suits your work.

The keyboard-driven editor uses slash commands for tables, charts, outlines, and code blocks, while the at-sign reaches pages, pins, and trails; Ctrl+K opens the trail index, Ctrl+P pins from the cursor, Ctrl+F searches, and a shortcuts panel shows the remaining commands. Writing is stored locally in a SQLite database that compatible tools can open, and optional end-to-end encrypted sync seals it on your device before transmission, with keys derived and retained there while the relay cannot read the content. Shizumu uses no account or analytics, keeping the writing under your control.

It fits daily journaling, project notebooks for developers, reading notes for students, and private thinking without a tagging system. Shizumu is open-source Productivity software for Linux, and version 0.8.1 fixes pin titles being overwritten and makes renamed pins persist, while nested outlines now render visibly; existing nested outlines are revealed without losing or adding content.

Requires Linux + Flatpak · Architecture: x86_64, aarch64

What's new in v0.8.1

A pin holds the whole passage. Select several blocks and pin them, and the pin keeps every one of them, in order, after an edit, after a restart and on your other device. Before, the pin came out with only the first block in it. Editing a pin of several blocks replaces each block on the page once, with nothing left over, and choosing a trail for a new page brings such a pin onto it whole. If part of a selection is already pinned, the app says so instead of offering a pin button that does nothing.

The desktop looks like the phone. The page sits on the desk as a sheet with a visible edge in cream, white and dark. Text that should step back uses a quieter colour instead of fading, and every screen was measured for contrast in all three tones. The page dots are crisp, with the current page as a small pill in the accent colour. Pin and modal titles rename in place, keyboard focus shows the same ring everywhere, and the interface labels use the phone's typeface.

On the phone, @ mentions a page, a pin or a new trail, and backlinks list the pages that mention them. Deleting a page from the pages of the day asks first. Ticking a task no longer jumps the page to its end, editing a pin no longer adds an empty line to it, and a table's last cell can be tapped again.

A trail can be renamed or deleted from where you look at it: the trail sheet on the phone, and ctrl+k on the desktop. Deleting a trail keeps its pages, without a trail, and trails inside it move up with their pins.

Pairing a device to an account that is already full no longer leaves the new device half set up. Its keys are saved only once pairing completes, it waits between retries, and the message says the account is full.

Smaller fixes: mentions follow a page renamed or deleted on the other device, backlinks include pages written on the other device, screen readers hear the desktop's notices and every icon button is named, reduced motion stills every animation, scrolling in a modal stops at its edge, and Android builds use 16 KB memory pages.
