shizumu

a writing app that never asks where to file it

you open a notes app with a thought.
it asks you which folder.

shizumu asks nothing. you write to think, you pin what turns out to matter, and it comes back when you open the project again. everything else stays in memory, searchable.

a minute of shizumu

the page

write to think

start writing. nothing to structure first, nowhere to file it. name what matters when it becomes clear, pin the lines worth keeping.

type / for a table, a chart, an outline, a block of code. type @ to reach a page, a pin, or a trail.

thinking about how writing shapes ideas
the best ideas come when you stop trying to organize them.
the act of filing kills the act of thinking.

trails

trail what continues

choose a trail and the page picks up context: the pins you kept there, already on it.

continuous is one living document, each day its own chapter. discrete is a fresh page each day; past ones live in memory.

a continuous trail: one living document, each day's focus stamped in as a marker
a discrete trail: a fresh page, the pins already kept on that trail carried onto it

pins

pin what matters

pin notes and boards from any page. they stay there across every session.

filter by trail, or search across all of it. the context comes with you.

pins: notes and boards kept from across a trail, one search over all of them

built differently

the problem is not that notes apps lose things. they keep everything, perfectly, and a year later you cannot tell which of it mattered.

they are built for piling in. every note is inventory, infinite recall is the promise, and the filing is the rent you pay for it. shizumu starts from the other end: you write to think, so the writing is fuel rather than artifact. what turns out to matter gets pinned, and everything else stays in memory where search still finds it without you carrying it forward. that one shift is where the rest comes from. nothing to structure first, nowhere to file it, and the pins on a trail as the six-month view of one thing.

continuous trails are the one intentional exception. when a single thread should genuinely keep growing. a book, a long project, a life-arc. you choose to trail it. that is a deliberate refusal of the default for one focused topic, not the default pile.

two questions stall a first sentence. how should this be structured, and where does it go. shizumu answers neither, so the sentence is the first thing that happens. what you get instead is a keyboard driven page with real tools on it, and a short way back to what you kept. it will not write for you either, and that one is not a stance: the writing is where the thinking happens, so handing it off would remove the point.

privacy · read it, run it, host it

the relay only ever sees ciphertext.

you can run your own and check.

sync is end to end encrypted. keys are derived on your device from a recovery phrase and never leave it, whether you use our relay or your own. the primitives, named: how sync is encrypted · threat model.

what's new in v0.7.7

this one went after the editor's papercuts.

this one went after the editor's papercuts. a lot of small things had been wrong for several versions. a new block landed on the sentence you had just written instead of on its own line. a blank line was parked above the first block on every page. alt+arrow would not move a block while you were still naming it. all fixed.

pins and images agree now. a pinned image shows the picture rather than a file row, and an image line offers pin and copy on hover, having been read as a blank line until now. empty blocks stop being pinnable: one used to pin as the word list. /image refuses a file that is not an image.

a block for the decision, not just the outcome. /decision keeps what you considered, what you chose, and because. the reason survives next to the choice, so the context is there when you come back to it.

tables and charts are ordinary blocks now. they carry a title, and their chip opens the same actions as every other block. before this, tapping the chip on an empty chart or table did nothing at all. /table asks for rows and columns, and the chart builder draws while you type.

the full list, and what caused it

a short look at v0.7.7. rendered from the actual ui.

memory

where everything else stays

search everything you wrote. follow a trail across time. browse pages grouped by date.

memory: every trail down the spine, one page or one pin at a time, filterable by trail and date

sync

the same thinking on every device you write on

write on the laptop, pin from the phone, pick the trail up on the tablet. keys are derived on your device and never leave it, so the relay only ever sees ciphertext.

your main device and a second one are free on our relay. run your own and there is no limit at all.

hosted sync · optional

the app is free. so is the sync.

shizumu is a private writing app, free on every platform. your writing stays on your device. sync is optional and end-to-end encrypted: the relay holds what it cannot read, and neither can we. we run one so you do not have to, or you run your own.

hosted free unlimited writing · main + secondary device · 1 gb attachments, encrypted.
self-deploy free, forever run your own relay. unlimited devices and storage. your server, your rules. one binary, agpl.

a relay costs money to run. supporting buys nothing; the app stays free either way. running your own relay: see the deploy guide.

on the way to v1.0

no dates yet. the open beta shapes v1.0. the people writing on it now decide what ships.

the app is free. if you would rather the relay kept running, support us on ko-fi.
