Your Data. Your Tools. Any AI. Private. Transparent.
Caiioo is a privacy-first AI workspace that runs in your browser's side panel — give one assistant your tools and data, and it does the work.
Use any AI model, keep every file and key on your device, and watch every step. No throttling, no hidden summarizing.
Runs on your device. Zero-retention AI providers. Your keys, your data, your rules.

How Caiioo Protects Your Privacy
AI subscriptions are convenient — but your conversations, files, and habits live on someone else's servers. Here's how Caiioo is different.
~$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: turn on the Pseudonymizer
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 [email protected] about the $48,000 invoice for Acme Corp, then call her at (415) 555-0132.
Email Dana Holloway at [email protected] 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.
