A library is private by definition
Nobody stands behind you at a bookshelf taking notes. The AI that reads your saves runs on your phone, and your library never touches our servers.
the library rules
Software should behave like a library.
Quiet, private and built to outlast its own building.
You already have a library. It’s scattered across four thousand screenshots, a reading list you stopped opening, voice memos called “New Recording 47”, reels you saved and never found again, and eleven apps that each hold a piece of what you thought was worth keeping.
None of it comes back to you. Saving turned into a polite way of forgetting. The tools were built to hold things, which was enough when storage was the hard part. Now the hard part is attention, and attention is what a saved article, a screenshot of a recipe or a thought spoken into your watch was asking for.
IKI reads everything you save, sums it up in a card, connects it to what you already have and brings it back when it matters. That took two unfashionable decisions. The intelligence runs on your device, because a library where someone reads over your shoulder isn’t a library. And everything is stored as plain markdown files, because we’ve watched too many “forever” apps take a decade of saves down with them.
file over app
Your files will outlive our company.
We designed it that way.
Files outlive apps
Your library is a folder of markdown files. Open it in the Files app, point Obsidian at it, back it up however you like. If IKI dies, your library doesn’t.
Reading is not a feed
There’s no infinite scroll, no engagement metric and no streak. You take a book from the shelf and put it back. The app is finished when you are.
Organising is the machine’s job
Noticing something worth keeping was the hard part, and you did it. Summaries, tags, connections and filing are on us, and they happen without being asked.
Honesty beats fluency
When you ask a question your library can’t answer, IKI says so instead of improvising. An index that lies is worse than no index.
No account, ever
A library card is not a login. IKI works the moment you open it, offline, with nothing to register, verify or reset.
Capture must cost nothing
Two taps from anywhere: the share sheet, Safari, your watch or a widget. If saving takes effort, you’ll stop saving.
Cards, not piles
A save you never revisit is a pile. Every item becomes a typeset card with the gist, because the point of keeping things is meeting them again.
Sharing is a gift, not a leak
Share a collection as a page. With a password, it’s encrypted on your device before it leaves, and we can’t read what you share.
The night belongs to the library
While you sleep and the phone charges, IKI re-reads, connects and catches up. You wake up to a fuller library, not a to-do list.
what iki is not
What IKI isn’t.
IKI is not a read-later queue that turns into a guilt list, a second brain that needs weekly gardening, or a notes app with an AI button glued on. It’s not a platform either: there are no followers, nothing trends, and nobody can see your library. You save things all day. IKI reads them, remembers where they went and, now and then, hands you a forgotten card at the right moment.
Start with one save.
Setup takes two minutes, and there’s nothing to organise afterwards.
