Sharing screen is really scary today with all PIIs and secrets sprawling around your screen, so I built [name-redacted], 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. visit [url-redacted] Feedback please <3

OP here. I built this because I recently caught myself almost pasting a block of logs containing AWS keys into Claude. The Problem: I need the reasoning capabilities of cloud models (GPT/Claude/Gemini), but I can't trust myself not to accidentally leak PII or secrets. The Solution: A Chrome extension that acts as a local middleware. It intercepts the prompt and runs a local BERT model (via a Python FastAPI backend) to scrub names, emails, and keys before the request leaves the browser. A few notes up front (to set expectations clearly): Everything runs 100% locally. Regex detection…

In a nutshell, dpScreenOCR can recognize text from the selected screen area, and then can copy it to the clipboard, add it to history, or pass it as an argument to an executable.
