Bank or police impersonation
A caller asks for an SMS code, approval of an unfamiliar sign-in or a transfer to a “safe account.”

Interpretation and help during phone calls
Bring Grandson into a call to interpret between Russian and Hebrew, help ask a question when booking an appointment, or make sense of a suspicious request.
Participation is by personal invitation.
Sample conversationIllustrative scenario
Caller
“I’m from your bank. Read me the code we just texted you.”
Grandson
“Keep the code private. Contact your bank using its official number.”

How to bring Grandson into a call
In the closed pilot, you can add the assistant to an outgoing or incoming call if your carrier supports merging calls.
Add the assistant to your call
Call the person you want to speak with or answer an incoming call. On your phone, tap “Add call,” dial Grandson, then choose “Merge calls.”
Ask for interpretation
Say “Переводи” (“Translate” in Russian). In a short live test, Grandson interpreted from Russian to Hebrew and from Hebrew to Russian.
Ask for help understanding a request
Say “Помоги разобраться” (“Help me understand” in Russian). If someone asks for a texted code, remote access or a money transfer, the assistant can explain the risk and suggest how to check the request. It can help you phrase a question and understand the reply, for example when making an appointment or asking about a ticket.
The assistant works with what it hears. It cannot verify a caller’s identity or authenticate the displayed number. The decision stays with the person on the call.
Planned for a future update
Make it easier to place calls with voice interpretation, for example to an Israeli health fund or a bank, so you can ask a question in Russian and hear the Hebrew reply translated into Russian.
03 / Research
Scenarios drawn from official guidance
Public advisories and accounts of real fraud schemes informed the AI’s instructions and the scripted test calls. Ordinary calls are included to check whether the assistant warns when it should stay quiet.
A courier sent to collect a bank card
Someone claiming to work for a bank says a courier will collect your card.
Fake technical support
The caller asks you to install an app, share your screen or grant remote access.
A supposed family emergency
Someone demands money or bail immediately and discourages you from calling your relative.
Investment recovery scams
A caller promises to recover lost investments if you pay an upfront fee.
Routine delivery or appointment
A comparison scenario. The assistant helps agree on a time or translate a phrase without an unnecessary warning.
04 / For investors
What works today and what the pilot needs to prove
Tavorad is testing whether a voice prompt during a call can help people make a more considered decision.
Available today
A telephone prototype with an assistance mode and Russian–Hebrew interpretation. An early live test confirmed merged calls and brief interpretation in both directions. Version 0.9.1 provides an Android app and a web app for iPhone. SMS receipt on Android has been confirmed.
What we will measure
In scripted calls we will track missed risky requests, false warnings in ordinary calls, time to the prompt and whether people understand the suggested next step.
What support would fund
Pilot telephony and voice AI, running the tests and improving the product based on findings. The first measurements will inform the scope and budget.
The references document the fraud schemes. The pilot will evaluate the reliability of the assistant’s guidance and its effect on decisions separately.

06 / About us
Why we started
We’re a small team. Grandson grew out of our founder’s personal experience. After people he knew were targeted by phone scammers, he decided to build an assistant that could help people decide what to do while the call was still in progress. Helping older adults who face this kind of pressure was especially important to him.
We work on a volunteer basis, and the pilot is free to join. We want this help to reach people who might otherwise be unable to afford it.
You can support Grandson by helping us test it, sharing feedback, telling someone who might benefit, or making a donation. If you’d like to help, please get in touch.
