A catalogue for everything you save

Saved is not the same as kept.

Kynosis takes the posts, videos, articles and screenshots you send it, gives each one a number, and files it where you will find it again. Send it from anywhere. Ask it anything. Export all of it whenever you like.

001 · How it works

Three seconds to save. Nothing to fill in.

01
Send it from where you found it
Share to Kynosis from Instagram, Threads, X, YouTube, Safari or Photos. The sheet closes immediately — nothing to name, nothing to choose.
02
It gets a number and a place
Every save enters the catalogue in order and gets the next number. Tags are proposed, a collection can fill itself from a tag, and both stay yours to overrule.
03
Find it by describing it
Ask for the article about sleep and cortisol you read in spring. Kynosis answers from your archive and shows the saves it read.
002 · The catalogue

A number, not a folder.

Folders make you decide where something belongs before you know why you kept it. Kynosis files first and lets meaning arrive later — the same save can sit in a collection, carry four tags, and still be reachable by its number alone. Numbers follow the order you saved in, so 001 is always your oldest; delete one and the ones after it move up. Nothing quietly disappears: on Kynosis Cloud a deleted save waits in Trash for thirty days.

How Superhuman keeps people past week one
retention
onboarding
in 1 collection
Three habits carry week-two retention: a first win inside four minutes, a same-day follow-up email, and one weekly ritual the user schedules themselves.
003 · The assistant

It answers with your own saves, and shows which ones.

Ask a question in the words you would use with a colleague. The answer cites the saves it read, by number, so you can check it in one tap. It reads nothing you have not saved.
“What have I saved about keeping people past the first week?”
Eight of your saves touch it, and they agree on three things. A first win has to land inside the first session — 812 puts it at four minutes. A same-day follow-up email carries more of week two than any in-product change: 808 has the numbers.

Summaries and transcripts
Long reads and videos come back as a short summary. Voice notes arrive as searchable text.
Collections that watch
Give a collection a tag and it keeps filling itself as new saves with that tag arrive.
Weekly digest
One short note on what you saved this week and what it adds up to, on the day you choose. Off in one tap.

005 · Privacy

Your archive is not training data.

Saves travel encrypted, and files and backups are encrypted at rest. On Core nothing you save is sent to an AI provider. On Pro the assistant reads only what you saved, only to tag, summarise and answer you, and nothing is used to train a model. Export the whole archive — files, notes, summaries — as plain Markdown and JSON at any time. No lock-in, and no account required to read what you have exported.
01
Encrypted in transit, and nothing leaves your iPhone unless you switch it on
02
Delete an item and it is gone in thirty days, permanently
03
Close the account and everything is erased within thirty days

Start with the next thing you save.

Kynosis is free until your archive is worth thinking with.
