Local-only file scanner catches hidden metadata before AI ingestion.

Strengths
  • Runs entirely in-browser using WebAssembly, ensuring zero data leakage.
  • Supports diverse formats like DOCX and PDF where steganography often hides.
  • Addresses the specific emerging threat of prompt injection via file uploads.
Weaknesses
  • Limited to client-side analysis, missing server-side enforcement capabilities.
  • UI feels generic compared to established security scanning tools.

SentryRF – A private, local-first Android app to detect hidden trackers

Uses RSSI time-series and sensor fusion — BLE plus magnetometer and ambient-light hints — to separate a 'passing' AirTag from a likely 'following' device, and then guides you to it with an audio 'Geiger counter' beacon. Smart, pragmatic feature choices (timeline, background protection, strictly local processing) make this actually useful in tense situations; caveat is hardware limits — claims about finding truly 'dead' GPS units or infrared cameras will depend heavily on your phone's sensors and will produce edge cases and false positives.
