Quietly capable. Entirely yours.

The best assistant is the one you can just talk to — already there the moment you need it.

Tap one key and Aletha floats up over whatever you're doing — a document, a browser, anything. Ask out loud or type, and the answer arrives on the spot. Aletha doesn't watch your screen or control your computer; it's simply always within reach, and always private.

Starting over every conversation is exhausting. A real assistant should already know you.

Aletha quietly remembers the things that matter — your work, your context, what you've said — and brings them back when they're useful. That memory lives on your Mac and nowhere else.

The work is hard enough without fighting your tools.

Built-in tools turn your own notes and materials into study guides and clear first drafts — fast, private, and offline.

A private machine should also be a clean, fast machine.

Aletha shows you exactly what's taking up space and helps you reclaim it — so the computer Aletha lives on stays fast and uncluttered.

You wouldn't hand your journal to a stranger. The vault is where your most private notes and information stay yours alone.

The vault is encrypted with AES-256 on your machine, and the key never leaves it. It's zero-knowledge — not even the founder can open it. That also means there's no "forgot password" link: if you lose your passphrase, what's inside is gone for good. That's the trade-off for encryption only you hold the key to.
