Traditional web applications send raw, sensitive user data to the server, relying on downstream **back-end** processes for redaction. This workshop challenges that paradigm by moving the privacy boundary directly into the browser.
In this hands-on session, Rasmus Longva Haugland shows participants how to build a privacy-first **front-end** architecture using Next.js. Participants will learn how to implement a local AI model that detects and masks personally identifiable information (PII) in real time, ensuring sensitive data is intercepted and sanitized before a network request is ever made.
Key takeaways:
How to integrate local, WebGPU-accelerated AI models into a real-world Next.js application.
Techniques for offloading heavy inference tasks to Web Workers to maintain a seamless user experience.
A concrete, privacy-by-design architecture that participants can adapt for their own production environments.
A pragmatic breakdown of where client-side AI meaningfully reduces compliance exposure and where it does not.
