Description

Reality Scam Interceptor is an AI-powered, privacy-first call protection system that detects scam calls by understanding conversations rather than relying on caller IDs. The system leverages Gemma as an on-device reasoning engine to continuously interpret conversational context, identify social engineering patterns, and generate real-time, explainable risk assessments while preserving user privacy. When a conversation exceeds a predefined risk threshold, Gemini Live is seamlessly activated—with the user's approval—to conduct speech-to-speech verification, gather additional conversational evidence, and validate the caller's intent before recommending whether to continue or terminate the call. By combining on-device intelligence with adaptive cloud-assisted verification, the system proactively protects users from evolving social engineering attacks.

# Reality Scam Intercept
> **Prototype developed at Reality Play**

**AI-powered, privacy-first call protection: an on-device Gemma agent that understands the
conversation, and a Gemini Live agent that takes the call and interrogates the caller.**

> *Formerly **RSD — Reality Scam Detect**. The project was renamed; some internal identifiers
> (the Xcode target, the `com.rsd.*` bundle IDs, and the Android `com.rsd.app` package) still
> carry the old `RSD` name and are intentionally left unchanged.*

## What is RSI?

Phone scams cost people tens of billions of dollars every year, and they almost always work
the same way: a stranger calls, impersonates an authority, manufactures urgency, and
pressures the victim into moving money before they have time to think. The tactics are
well-known — but in the moment, under stress, they're hard to recognize.

RSI detects scam calls by **understanding the conversation**, not by looking up the caller's
number. It runs a two-tier agent:

1. **Detect — on-device, always.** **Gemma 4 E4B** (via Google's **LiteRT-LM**) runs as a
   *stateful
