Hey folks, so I built a chrome extension called [name redacted], an AI assistant that automatically completes your browser tasks for you. You simply enter your task, and [name redacted] uses GPT-4V to figure out the best browser action to perform next repeatedly until the task is accomplished. The idea is that you can delegate your personal tasks like online shopping or making reservations to [name redacted].

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
