Private, On-device Agentic AI
Vesper is a private AI assistant that lives entirely on your iPhone.
No account. No cloud. No catch.
Talk to Vesper the way you'd talk to a sharp, thoughtful friend. Ask a question, think out loud, get a second opinion — all of it stays on your phone, all the time.
TWO MINDS, YOUR CALL
Quick is fast and fully offline once it's downloaded — no server, no traffic, nothing leaving your phone. Thoughtful takes its time, and if you switch on THE WEB, it can look things up for you: a few searches, a couple of pages read, always visible when it's happening.
ACTUALLY PRIVATE
Vesper doesn't have a backend. There's nothing to log in to, nothing syncing to a server somewhere, no analytics watching how you use it. Your conversations stay where you had them — on your phone.
SETTINGS THAT SPEAK YOUR LANGUAGE
Turn THE WEB on or off, switch minds, adjust how Vesper talks to you — all in plain English, no menus to hunt through.
CONTINUITY ENGINE
Vesper remembers the shape of your conversations, so you're not starting from zero every time you open the app.
Vesper now uses clearer, more natural status messages while preparing responses. Menu screens have cleaner, more consistent headers, and the About page now highlights what’s new. This update also includes minor interface improvements and bug fixes.
