A personal assistant that's actually private.
Everything you'd want it to do, without handing over your data. Ballast reads your email, turns it into to-dos, texts you reminders you can answer, and warns you when something looks like a scam.
Example conversation
To-dos from your inbox
Bills, deadlines and replies you owe, found as soon as you connect Gmail.
Reminders you can answer
Reply "later" or "ping me in 20" and Ballast reschedules.
Scam and account alerts
Phishing, password resets you didn't ask for, and breach notices.
Replies you approve
Ballast drafts. Nothing is sent until you tap Send.
Your phone keeps your information. A sealed AI does the thinking.
Ballast splits the work in three, so the smart part never holds your data. Ballast is in private beta, and we'll publish technical details as each part is finished.
The vault
Your email, tasks, reminders, chat history and memories are stored only on your phone, encrypted with keys held in its secure hardware.
The brain
For each task, your phone sends only what that task needs to an AI model running in hardware-protected confidential computing. It's designed to answer without storing your data.
The hands
When you approve an action, your phone carries it out. The AI never sees your passwords, payment details or logins.
Vault → only what the task needs → verified enclave → answer → back to your phone
Your phone checks the seal firstThe enclave proves which software it's running. If the proof doesn't match the approved version, your phone sends nothing.
Encrypted all the wayRequests are encrypted so that only the verified enclave can read them, not us and not anyone in between.
What Ballast never does
- AdsWe don't sell your information or use it for advertising.
- TrainingYour email and chats are never used to train AI models.
- SendingNo email goes out, and nothing is bought or deleted, without your explicit tap.
- StorageYour email and chats are not stored on our servers.
Ballast uses Gmail access to read messages for to-dos and security alerts, and to send email you approve.
