Show HN: Entropy – Sharing screen is scary in SaaS age

Sharing screen is really scary today with all PIIs and secrets sprawling around your screen, so I built Entropy, a small Chrome extension that spots API keys, tokens, emails, and throws a blur overlay on them in real time.

The goal is to make screen-sharing feel safe again without adding steps to a demo.

Everything runs locally—regex + entropy heuristics compiled to WASM—and the extra CPU cost averages ~1 ms per mutation on my M1.

Custom rules can be added with a JSON file for teams that have proprietary token formats.
