A vault that reads, so you don't have to.
Most storage keeps files. KiOO understands them — and turns a folder of documents into answers you can trust.
Ask, don't dig
Ask in plain language and KiOO reasons across your whole vault — reading, cross-referencing, and citing sources as it answers. You get the fact you need, with a link to the exact page it came from.
Understood on arrival
The moment a file finishes uploading, KiOO writes a clear summary of what's inside — so a folder of dense PDFs becomes something you can skim in seconds.
See anything, download nothing
PDFs, documents, images, audio, and video — with hover-to-scrub previews — all open instantly in a clean reader. No plugins, no exports.
Comment on the file itself
Leave threaded comments on any document — pinned to a PDF page, a line of text, or a moment in a video. Mention people, react, and resolve, the way you already work.
Exactly the right access
Share a folder as viewer, commenter, contributor, or editor. Access flows down the tree, so you set it once and it just holds.
Three steps.
Then it's just asking.
01Bring your files in
Drag in documents, images, recordings, whole folders. KiOO reads and indexes each one as it arrives.
02Understood on arrival
Every file gets a plain-language summary the moment it lands — the key facts pulled out and indexed privately in your vault.
03Ask in plain language
One question, one answer, one source — cited, and clickable straight through to the page it came from.
Yours. Provably.
A vault is only useful if it's actually private. KiOO is built like it holds your passport — because it does.
- ✓Passwordless by default. Sign in with a passkey — your face, fingerprint, or device key. Nothing to remember, nothing to leak.
- ✓Permission-filtered retrieval. Every search and every answer is filtered by what you're actually allowed to see — never more.
- ✓Your originals, the source of truth. Files are stored encrypted and never used to train anything; your originals always stay canonical.

Questions, answered.
Is my data private?
Yes. Sign-in is passwordless via passkey, every query is filtered to what you're allowed to see, and your original files remain the single source of truth — everything else is rebuildable from them.
What can I put in KiOO?
PDFs, text and office documents, images, audio, and video. Most open instantly in the built-in reader, and KiOO indexes them so you can ask questions across the lot.
How accurate are the answers?
Every answer cites the files it came from, so you can verify in one click. When KiOO can't find support in your documents, it says so rather than guessing.
Can I use it with other people?
Share any folder at the level you choose and comment directly on files — threads, mentions, reactions, and resolve included.
Your files, finally answerable.
