What it actually does
There is no new app. You text or call it. It connects to your email, messaging and accounts, and is trained to use a phone and a computer the way a person does — including placing calls on your behalf and following a task until it is resolved.
Where it is strongest
The errands other agents cannot touch: booking an appointment that requires a phone call, disputing a bill, chasing a supplier, monitoring availability and acting when it opens up.
Where it struggles
Access is invite-only and US-focused, so you may simply not be able to use it. Its permission model — connected accounts, stored credentials, screen and location access — has drawn public privacy and security criticism, and it is the least appropriate of the agents here for company or regulated data.
How to get good results from it
Treat it as a personal assistant, not a work one. Give it errands with a clear success condition, and keep it away from anything covered by a company data policy.
Strengths and weaknesses
Strengths
- Handles the errands other agents can't: booking appointments, making calls, chasing outcomes.
- No new app to learn — it works over text and voice.
- Early users describe it as unusually persistent at finishing a task rather than reporting back.
Weaknesses
- Invite-only, so you may not be able to get in at all right now.
- Its access model — connected accounts, stored credentials, screen and location — has drawn public privacy and security concerns.
- Least suitable of the agents here for company data or regulated work.
What users report
User-reportedEarly-user accounts describe booked medical appointments, negotiated bills and monitored ticket availability. Press coverage has focused as much on the privacy trade-off as on the capability.
Who it suits
- People whose bottleneck is personal admin and phone calls
- Anyone comfortable trading broad account access for task completion
Who should skip it
- Anyone handling regulated, client or company-confidential information
- People outside the United States, for now
Verdict
Pick it if your bottleneck is personal admin and phone calls rather than documents — and you are comfortable with the access it needs.
