Challenge: Detecting modern fraud beyond calls and SMS
Digital fraud has evolved rapidly in recent years. Beyond scam calls and SMS, fraudsters increasingly use AI-generated images, voice messages, screenshots, and printed materials to deceive users.
A survey conducted in February 2025 showed that 96.8% of Taiwanese users had received scam messages, while 32.8% encountered scam images or AI-generated voices. These emerging formats made fraud detection more complex and harder for everyday users to assess.
With over a decade of experience in fraud prevention, Gogolook set out to enhance its consumer-facing tools to help users identify fraud risks in real-world scenarios, not just on phone calls.
"To quickly detect fraud content, we looked for a generative AI model that delivers accurate and consistent text analysis results within the shortest time. During our comparison test, Google Cloud's Gemini 2.5 Pro outperformed other large language models in terms of speed and cost."

With Content Checker, users can:
- Upload screenshots of suspicious messages
- Take photos of physical flyers or printed material
- Receive a fraud risk assessment within seconds
- Document AI extracts text from images submitted by users
- Gemini 2.5 Pro on Vertex AI analyses the extracted content and compares it against known fraud patterns
- Risk assessment results are delivered to users in approximately five seconds
Our role: Accelerating development and time to market
