Censr blacks out API keys, passwords, and sensitive data on your screen — before they ever hit your stream. Shows up as a camera in OBS, Zoom, Meet & Discord, and protects automatically the moment you go live. 100% on your Mac. Nothing uploaded, ever.
# what your audience sees — sealed in real time OPENAI_API_KEY = AWS_ACCESS_KEY_ID = DB_PASSWORD = func processFrame(buffer) { return redact(buffer) // your code stays visible }
Every other "blur my screen" tool only works inside a Chrome tab. But you don't leak secrets in a browser — you leak them in your terminal, your editor, your .env file, a database GUI. Censr watches all of it, because it works at the system level, not inside one app.
Terminal, VS Code, database GUIs, native apps — not just the browser. Wherever a secret appears, it gets sealed.
Detection runs on your Mac with Apple's on-device engine. Your screen never leaves your machine. No cloud, no logs.
Censr appears as a virtual camera in OBS, Zoom, Meet, Teams & Discord. Set it once and every audience is covered.
Open it once and forget it. Censr starts protecting the moment your camera goes live, and stands down when you're done.
Your feed runs a beat behind real time, so a freshly-typed key is scanned and sealed before a single frame ever airs.
One hotkey — ⌘⇧B — instantly blacks out everything, even mid-stream from another app. Your last line of defense.
Censr reads the window or screen you're sharing — privately, on-device — and feeds a clean copy to its virtual camera.
It recognizes API keys, tokens, passwords, .env values and PII the instant they appear on screen.
A safety buffer holds the feed a beat, so every secret is blacked out before it reaches your audience.
A tool that watches your secrets has to be trustworthy about its own. So here's exactly how Censr handles your screen — and what it won't promise.
