Pakistan Notice Helper: A small AI safety tool built with Qwen3.5 4B to help people identify suspicious messages in Pakistan

Pakistan Notice Helper is a safety-focused AI tool designed to help people in Pakistan understand suspicious messages before clicking links, calling numbers, sharing OTPs, or making payments. It works as a triage tool that accepts text or screenshots and returns a risk label, explanation, visible red flags, and safe next steps.

The final production model uses Qwen3.5 4B Q8 through llama.cpp, chosen after testing larger alternatives. The app supports both English and Urdu, with Urdu mode including right-to-left layout and model responses generated in Urdu script. It identifies warning signs such as urgent threats, requests for OTPs and passwords, suspicious payment links, and impersonation of banks or government departments.

The developer found that Qwen3.5 4B rated around 80/100 for this task compared with Qwen3.6 27B at around 95/100, but the smaller model's lower cost, faster loading, and practical deployment on smaller machines made it the better choice for a focused safety tool with clear scope and strict output constraints.
