    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]. You can also use him professionally to find leads on LinkedIn, send status updates to your boss, or research your competitors and write an analysis document. I’m wondering if you would…

    I've been experimenting with Claude Code, ChatGPT Agent, and OpenClaw to perform more open-ended tasks for me online. A big blocker I've hit on shopping and research tasks is the agent getting a key piece of info wrong. For example, in one case, my agent decided to add a brand I don't like to the cart because the site flagged it as almost sold out The HN crowd is probably pretty aware of the threats and can avoid them while browsing. But what about their agents? I tried prompting, but it was ineffective, because once the AI saw the threat, it polluted/distracted its context Looking at…

    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…

    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
