Hand it off.
Your phone finishes it.
StareBrain is the errand agent for Android. Say what you need and it works through your real apps, one step at a time: a bill negotiated, a late invoice chased, a surprise party quietly organised. You see the plan first, and before anything you can't undo it stops at the Stop Line and asks. It's in its final stretch. Join the waitlist for early access.
Say it. See the plan. It happens.
Most phone errands aren't hard. They're just five screens long.
So stop doing them. Hand them off.
Say what you want, in plain words.
StareBrain shows the plan, then works through your apps.
At the Stop Line it waits for your yes. That's a hand-off.
What it's built to do. Nothing more.
Takes a hand-off
Say the errand in plain words. No commands to memorize, no menus to dig through.
Stops at the Stop Line
You see the plan first, and texts always ask. Inside apps, it pauses at the Stop Line: before anything you can't undo.
Stays inside permission
Only the capabilities you've turned on are used. Switch any of them off, any time.
Design targets — not yet measured in production
Not one thing at a time. As many as it takes.
A simple assistant runs one command and stops. StareBrain is built to read intent, wait on conditions, chain steps together, and only ask for your confirmation once — on the whole plan, not each piece of it. These are the behaviors it's built around.
Handle a schedule conflict
“John just double-booked me” → checks both events, drafts a reschedule message to John, waits for his reply, updates your calendar only once he confirms.
Throw a surprise party, quietly
“Throw Maya a surprise party on the 14th” → finds her free window without tipping her off, polls guests in a private thread, shortlists venues under budget, tracks RSVPs and who's bringing what.
Watch for something, then act
“Text me when the contractor replies, then add the quote to my budget sheet” — waits on a condition, then executes, with no further prompt from you.
Rescue a cancelled flight
“My flight just got cancelled” → finds your booking, compares rebooking options, messages the hotel and your pickup, then asks before anything irreversible.
Close out an apartment move
“I'm moving out on the 30th” → finds every utility and subscription in your email, drafts the cancel/transfer notices, books the walkthrough around your calendar, reminds you about the keys.
Chase a late invoice
“Get Dan to pay invoice 214” → reminds on a schedule, firms up the tone on Friday, stops the moment payment lands, and flags anything pointed to you first.
Dispute a double charge
“That charge looks wrong” → spots the duplicate, gathers the receipts, drafts the dispute, tracks the reply.
Negotiate a bill down
“My internet bill went up — get it lowered” → pulls the last six bills, asks for a retention rate, compares rival offers, and holds any contract change for your yes.
