You get a clear warning

Tosi tells you plainly when to hang up and texts your trusted family member right away.

A personal reason to build

For our families.
And our neighbors.

MyTosi started with something familiar: getting multiple scam calls every week, and thinking about the people we love picking up those same calls.

It was built by someone who wanted to help protect family and community. Clear guidance at the right moment can help a loved one recognize a suspicious call and bring family into the loop.

An early pilot, built with care.

Recognizing the warning signs

What Tosi listens for.

Scam calls can sound convincing. Tosi checks for common patterns like these.

Gift card demands

Someone asking you to buy gift cards and read out the numbers.

Someone posing as an official

A caller pretending to be your bank or a government agency.

Pressure to act right now

Urgent threats or demands that leave no time to stop and think.

Requests for security codes

A caller asking for a one-time code or other private account details.

Remote access requests

Someone asking to take control of your phone or computer.

“Safe account” transfers

Pressure to move your money to another account to “protect” it.

Tosi can miss a scam or flag a legitimate call. It offers support, not a guarantee.
