You already know which AI you like. Now give it your real work.
Caiioo is a privacy-first work platform that ties everything together — your files, your devices, your connected apps, and your favorite AI — from phone to desktop to browser extension.
Privacy-first, so the work you'd never paste into a chat box is exactly the work you can hand it — your real folders, your builds, the live web, every step visible. On whichever screen you're near: Chrome, Edge, macOS, Windows, and Linux, with the Android beta on Google Play and iPhone in early access. Lock your phone mid-task and your desktop finishes it.
Runs on your device. Zero-retention AI providers. Your keys, your data, your rules.

Start it on your phone. Your desktop finishes it.
Switch devices, models, and providers on a dime. Your history and memory ride along, end-to-end encrypted so only your devices can read them, and fully exportable.
Lock your phone mid-task
With auto-continue on, your desktop picks up the running task, finishes it, and the answer is waiting when you look at your phone again.
Drive your desktop from the couch
Send from your phone into a desktop-hosted conversation and it runs with your desktop's folders, apps, and terminal — streaming live on both screens.
Your memory travels with you
What it learns working with you — your projects, your preferences, even the model you just picked — is already there on the next device. Synced end-to-end encrypted; only your machines can read it.
Your sessions are reachable from any browser, too — over your own LAN, or through an encrypted single-tenant relay that joins your devices into a private constellation.
The Android beta is on Google Play now, and the iPhone app is in early access with a small tester community — this is the newest thing we've built, and we'd like more hands on it.
Become a mobile tester
Your work lives on your device, not theirs.
AI subscriptions are convenient — but your conversations, files, and habits live on someone else's servers. Here's the difference.
~$20/mo for one provider
Your question, context, and any files you share
Stored in their database alongside millions of other users
Your conversations may train their models, feed analytics, or be reviewed by staff
Logs kept for 30–90+ days. Sub-processors may get copies too.
Your data on their servers, under their terms, subject to change
Pay only for what you use — often less
Your question, context, and any files you share
Caiioo runs locally. Your data never leaves unless you ask it to.
Your prompt goes straight to the AI provider with zero data retention. Response comes back. Nothing stored.
Conversation history, files, preferences — all local. Only you have access.
Your data on your device, under your control, always
Go further: filter personal data from the AI
Even with your own key, your prompt still reaches the AI provider you chose. Turn on the Pseudonymizer and every personal detail — names, emails, phone numbers, companies, account numbers — is swapped for a realistic, made-up stand-in before the request ever leaves your device.
Email Jane Doe at jane@acme.com about the $48,000 invoice for Acme Corp, then call her at (415) 555-0132.
Email Dana Holloway at m.reyes@example.org about the $48,000 invoice for Northgate Ltd, then call her at (628) 555-0148.
Highlighted values are synthetic — made up on your device, never real people or accounts. The dollar amount and intent stay intact, so the model still reasons correctly.
Only the remote model sees stand-ins. Everything on your side uses the real data:
When the model answers, your device swaps the stand-ins back to the real values for every tool it runs and for what you read — so actions hit the right inbox, the right invoice, the right number. The real-to-stand-in map never leaves your device; detection runs on-device, free on every platform.

Real folders, running builds, live web pages, finished documents — on your desktop, your phone, and your browser.

Stays fast as your toolkit grows
It picks up only the tools your turn needs — dynamic per-turn selection, not a fixed toolbox.
Change your mind mid-run
Interrupt a running task and redirect it mid-flight — an interjection queue keeps your context intact.
Remembers more of your project
Redundant context is deduplicated just before each request, so more of your work fits in the same window.
In your browser today
One compact interface on every platform—browser, desktop, and mobile. In the browser, no admin rights required.
Model intelligence you can check
Nobody can keep thirty models straight — we can't either, so we measure. Caiioo Benchmarks publishes the speed, cost-per-task, and capability rankings we use to choose, so you can check our work and pick for yourself.
Every step auditable, every answer traceable — with a public benchmark harness to check our work.
