Filled the shipping form from your saved address. Found the checkout button — this looks like a payment action, so I stopped to ask first.
An agent that acts in your browser,
not just describes what to click.
Acts in your live tab
BrainClaw reads the page, clicks, types, and navigates in the tab you already have open — narrated in a side panel while you watch.
Structured, not pixels
Pages are read as a structured snapshot of interactive elements, not screenshots — fast, deterministic, and cheap, with a vision fallback planned for pages that need it.
You choose what it can touch
Every new site starts as Ask each time. Allow a site always, or set it to Never — your call, per site, any time.
Sensitive actions always ask
Payments, credentials, account changes, sending a message, or agreeing to something — a fixed set of categories always asks first, no matter what a site is allowed to do.
Nothing happens until you say so.
Every site starts at Ask each time. A fixed set of sensitive categories — payments, credentials, account changes, sending a message, agreeing to something — always asks first, no matter what you've allowed for that site.
