Choose this installAny AI brand. Every device. One memory.
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 iPhone and iPad beta is on the App Store; the Android beta is on Google Play. We'd like more hands on it and more feedback.
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.

💵Pay per use — most people spend less than a subscription
🚫Zero analytics, zero profiling, zero tracking
🔌Connect your own accounts directly (Google, email, etc.)
🛡️Your terms. Your data. Always.
Optional layer
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.
You type
Email Jane Doe at [email protected] about the $48,000 invoice for Acme Corp, then call her at (415) 555-0132.
The remote AI only sees
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:
Remote AI model
Stand-ins only
Tool calls & your files
Real values
The reply on your screen
Real values
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.
