AI-Assisted Wayback Machine Extension Using Client-Side Prompt API

Navigating archived pages on the Wayback Machine requires significant manual effort. This project builds an experimental Chrome extension that uses Chrome's built-in Prompt API with Gemini Nano to automatically summarize archived pages and detect broken or soft-404 captures, all processed locally on the user's device for privacy. Deliverables include a working MV3 extension with page summarization, two-layer soft-404 detection using DOM signals and the CDX API, a lightweight overlay UI, and a public evaluation report.
