Chrome extension, free in beta

Start from blank.

An AI that works next to you and becomes your second reader

blank lives in Chrome's side panel. It reads what you're reading, sends every message to the model that fits it, and remembers what matters, on your computer.

Add to Chrome Then press AltB on any page

What it does

Four things, done smoothly.

Next to you

It lives next to you.

blank opens beside the page you're on and never takes over your tab. It reads the page when your question is about it, looks at a screenshot when it can't read the text, and builds small apps that live on your computer.

Routing

Every message goes to the model that fits it.

Jev, a decision model from TypeSafe, reads each message and picks the model and how much power it needs, in a fraction of a second. Simple things stay fast. Hard things get the strongest model.

Examples. Jev decides each message as you send it.

Memory

It remembers what matters, only when it matters.

Tell it once how you write or what you're working on. Memory stays on your computer, goes into a message only when it changes the answer, and every line can be edited or deleted. Bring what ChatGPT or Claude already know about you.

Acting COMING SOON

Soon, it does the clicking.

Ask blank to fill in an application and it will type into the page for you, field by field, while you watch and keep browsing.

  • Your voice never leaves your device. Speech is turned into text locally.
  • Messages pass through, they aren't kept. No ads, no selling data, no training on your chats.
