Browser-Side Quarantine And Removal Tool For Unsolicited On-Device AI Models Like Chrome Gemini Nano
Chrome silently writes a 4 GB Gemini Nano model (weights.bin) to disk on capable systems; manual deletion triggers automatic re-download, and the most user-visible 'AI Mode' pill in the address bar still routes to cloud servers anyway. Researchers argue the silent install likely violates EU ePrivacy and GDPR rules. There's clear demand for a small cross-platform tool that detects browser-bundled local AI models, lets users quarantine the weights, blocks redownload via OS-level rules, and reports back which features actually break (mostly nothing for typical users).
An extension can't fully prevent Chrome's redownload; the real product is an OS-level binary that watches the user-data directory plus a hosts/firewall block of the model CDN endpoints. Ship it as a one-click installer, not as 'click here to add this to your weekend project'.

Today the only counter is per-vendor flag-hunting and accepting auto-redownload. There is no cross-browser tool that watches for, quarantines, and prevents redownload of bundled AI weights, and no SaaS/news source that tells users which browser-side AI models exist on their disk right now.
