Censr is a Mac app that automatically blacks out API keys, passwords, and personal data on your screen — before they ever hit your livestream or screen-share. System-wide (terminal, editor, browser, native apps — not just a browser tab), 100% on-device (nothing uploaded), and it shows up as a virtual camera in OBS, Zoom, Meet & Discord. Follow to get notified at launch — the first 100 founding members get it for $19.

Hey Product Hunt I'm Todd. I build apps live on Twitch — and for two years I streamed with a low-grade dread that one careless cat .env or a paste into the wrong window would flash an API key to everyone watching. Leaked keys are real money and real damage, and they're permanent the second they air. Every "blur my screen" tool I found was a browser extension — useless, because I don't leak secrets in a Chrome tab. I leak them in my terminal, my editor, a .env file, a DB GUI. So I built Censr. Censr watches your whole screen on-device (Apple's Vision engine — nothing is ever uploaded), detects API keys, tokens, passwords and PII the instant they appear, and seals them behind a black bar before the frame reaches your audience. It runs a tiny safety buffer so a freshly-typed key is caught before it airs, and there's a panic hotkey (⌘⇧B) to black everything out instantly. It shows up as a virtual camera, so it works in OBS, Zoom, Meet, Teams & Discord. The thing I'm most careful about: no detector is perfect, so Censr is built as defense in depth — buffer + panic key + an always-blur list — not a magic "100% safe" promise. Free 14-day trial, then a one-time price (first 100 founding members get it for $19). Mac-first; Windows is on the roadmap. I'd love your feedback — especially edge cases where it misses something. Ask me anything!

How does it handle dynamic content like password manager autofill that pops up mid-screen-share? Curious whether the detection keeps up with stuff that wasnt visible when you first set it up.

Scared of leaking an API key on stream. I built the fix — would love your eyes before July 1.

Hey Product Hunt I'm Todd. I build apps live on Twitch, and for two years I've had the same low-grade fear running in the background: one careless cat .env, one wrong window shared, and an API key is on the internet forever.

Every tool I found to "blur my screen" was a browser extension which is useless, because you don't leak secrets in a Chrome tab. You leak them in your terminal, your editor, a .env file, a database GUI. So I built Censr: a Mac app that watches whatever you're sharing and blacks out API keys, passwords, and PII before they reach your stream or screen-share. It shows up as a virtual camera in OBS, Zoom, Meet & Discord, runs 100% on-device, and has a panic hotkey ( B) for the "oh no" moments.

The one thing I won't claim: that it's perfect. No detector is. It's defense in depth a safety net for the slip-ups you can't catch yourself not a "100% safe" promise. I'd rather be honest about that than oversell it.

We launch July 1. Two questions for this crowd while I've still got time to act on the answers:
