Stream your code.
Not your secrets.

A complete streaming app with a safety net built in. Go live straight to Twitch — no OBS — with your mic, game audio, camera & chat overlay. And anything sensitive on screen — API keys, passwords, personal info — gets blacked out before your audience sees it. Prefer OBS or Zoom? Censr drops in as a camera there too. 100% on your Mac, nothing uploaded.

Why Censr

Browser extensions can't see your terminal.

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.

What it does

A whole streaming setup — that can't leak.

Go live without OBS

Stream your protected screen straight to Twitch (or YouTube / any RTMP) with one click. No OBS, no scene-wiring — everything Censr hides is hidden on the live stream too.

Everything on screen, sealed

API keys, passwords, .env, tokens & PII across your terminal, editor, database GUIs and native apps — blacked out before a single frame airs.

Your whole studio

A built-in audio mixer (your mic + desktop/game audio, with live levels), a drag-and-place facecam, and a chat overlay — right on the feed, no extra tools.

Works with pro audio gear

Streams smoothly from pro USB or Thunderbolt audio interfaces — Apollo Twin and the like. If you run real audio gear, it just works — no fiddling, no workarounds.

Switch it up, mid-stream

Change your mic or audio interface, or swap what's on screen — live, without ever dropping the stream. Redact just one window the moment your workflow changes.

Safe chat, built in

Read your Twitch chat inside Censr, with a safety lens that flags risky links so doxxing and TOS-bait don't slip past. Set your title & category without leaving.

Panic button

One hotkey — ⌘⇧B — instantly blacks out everything, even mid-stream from another app. Your last line of defense.

Zero-leak safety buffer

Your feed runs a beat behind real time, so a freshly-typed key is scanned and sealed before a single frame ever airs.

100% on-device

Detection runs on your Mac with Apple's on-device engine. Your screen never leaves your machine. No cloud, no logs.

Works in OBS & Zoom too

Prefer your current setup? Censr is also a virtual camera in OBS, Zoom, Meet, Teams & Discord — same protection, drops right in.

How it works

Capture. Detect. Seal.

Capture

Censr reads the window or screen you're sharing — privately, on-device — and feeds a clean copy to your Twitch stream (or its virtual camera for OBS/Zoom).

Detect

It recognizes API keys, tokens, passwords, .env values and PII the instant they appear on screen.

Seal

A safety buffer holds the feed a beat, so every secret is blacked out before it reaches your audience.

The Censr Stream cockpit — Twitch chat with a safety lens on the left, the protected preview in the center, and the Studio panel on the right with Go Live (no OBS), audio mixer, camera and chat overlay controls, plus a Start Protecting / Panic / Go Live toolbar.
// the cockpit — chat, protected preview & the whole studio, one window
Censr protecting a .env file live — OpenAI, Anthropic, Stripe, AWS, GitHub, database and password values all blacked out with CENSRED bars, while non-secret lines like APP_NAME and PORT stay visible. The toolbar reads 'TextEdit — fake.env' with a live hidden-secret count.
// what your audience sees — every secret sealed, your real work still visible
Censr Stream's Studio panel with the audio mixer open — microphone toggle, input-device picker, a live level meter and volume, plus desktop/game audio with its own slider — all built in, no extra tools.

On-device by design

Your screen never leaves your Mac.

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.

Detection runs locallyOCR and secret-detection happen on your Mac with Apple's on-device engine. Your screen content is never uploaded, streamed to us, or stored anywhere off your machine.
No account, no cloud, no telemetry on your screenYou don't sign in to use it. Censr doesn't phone home with what's on your display. There are no server logs of your screen, because nothing leaves the device.
Honest about the limits — defense in depth, not a guaranteeNo detector catches 100% of everything. That's why Censr runs a safety buffer (so secrets seal before they air) and gives you a panic key and an always-blur list. We'll never claim "100% safe" — we'll give you layers.

One solid piece at a time — built right, not rushed. No hard dates, but here's the order.

Now — Mac ● shipping

Full solo streaming — go live to Twitch (no OBS) with a mixer, facecam & chat overlay, while secrets & PII are auto-hidden. Also a virtual camera, panic key, 100% on-device.

Next — Nudity & “don't-get-banned” protection ● in development

Catches accidental NSFW & bad sites before they air. Unlocks gamers & IRL. First pieces are being built and tested right now.

Next — Live Guard

Forgot you're still live? Step away and Censr blacks out the feed automatically — so nothing airs while you're gone.

Then — Screenshot redaction

Drop a screenshot on Censr, get a share-safe copy back — same engine, one frame at a time. For Slack, bug reports & social.

Then — Windows

For the gaming crowd, on the platform they actually stream from.

Later — Faces & doxxing · Teams / meeting mode

IRL privacy + business screen-share protection.

On Windows?

FAQ

The honest answers.

Does my screen get uploaded anywhere?
No. All capture, OCR, and detection run locally on your Mac using Apple's on-device engine. Your screen content never leaves your machine — there's no cloud, no account, and no log of what's on your display.
What does Censr actually catch?
API keys and tokens (OpenAI, Anthropic, AWS, Stripe, GitHub, Google, Slack, JWTs, private keys), .env values, password fields, strong-password-shaped tokens, and common PII like emails, SSNs and card numbers — by pattern, the instant they appear. Anything else, you add to your Always-Blur list and it's sealed everywhere it shows up.
Is it a 100% guarantee?
No — and we'll never claim that. No detector is perfect. Censr is built as defense in depth: a safety buffer seals secrets before they air, a panic hotkey blacks everything out instantly, and the always-blur list covers anything pattern-matching can't. Honest beats sorry.
Do I need OBS?
No. Censr streams straight to Twitch (or YouTube / any RTMP) on its own — with your mic, desktop/game audio, camera and chat overlay built in. Just paste your stream key and hit Go Live. Prefer OBS? See the next answer — it works there too.
Does it work with OBS, Zoom, and Meet?
Yes. Censr also installs a virtual camera, so it appears as a camera/source in OBS, Zoom, Meet, Teams, and Discord. Pick "Censr" as your source and your redacted screen is what the audience sees. Use it standalone or inside your current setup — same protection either way.
Is it really Mac only?
For now, yes — v1 is Mac (macOS 14+, Apple Silicon and Intel). Windows is on the roadmap; add your email to the Windows list above and you'll be first to know.
How does the free trial and pricing work?
Download free and use Censr fully for 14 days — no card up front. To keep going it's a one-time purchase (no subscription): $29, and the first 100 founding members get it for $19 with code EARLYBIRD. The price rises as new protection ships, but whatever you pay is locked in for good — and every purchase is backed by a money-back guarantee.
What if it doesn't work for me?
Email me and we'll make it right. Censr is built by one developer who streams behind it — your feedback goes straight to the person who can fix it.
