How I built a Chrome extension that reads Terms of Service using AI — and what I found

Short summary

A developer built ToS Radar PRO, a Chrome extension that uses local AI inference to scan Terms of Service and Privacy Policies for six categories of risky clauses including AI data scraping, forced arbitration, and auto-renewals. Testing across 50+ sites found 97% reserve the right to train AI on user data and 100% can change terms anytime. The extension runs entirely in-browser with no external API calls.

  • •Chrome extension uses local AI to flag dangerous ToS clauses
  • •97% of tested apps reserve right to train AI on your data
  • •Everything runs locally — no data leaves the browser

Generated with AI, which can make mistakes.
