Now a real camera on your Mac

Speak. It shows.

Capturia is the AI producer inside your camera. Download it, select Capturia in Zoom, Meet, or Slack like any webcam, and talk. Your numbers, your charts, and your audience’s votes land on your live feed, right as you say them.

Everything above is real. The exact overlays the engine renders, replayed on a loop. On a call, you just talk.

Try it live in the browser demo, free at /studio. The macOS app is a real camera: select Capturia in your call app and this, over your actual webcam, is what your audience sees.

How it works

A producer in your menu bar. Zero crew.

If you can hold a conversation, you can run Capturia.

1

Download and open

Grab the DMG, drag Capturia into Applications, and launch. It lives in your menu bar next to the clock, producer on standby.

2

Install the camera, once

Click Install camera and flip the switch macOS shows you. One approval, about a minute. From then on Capturia sits in every call app's camera list, right next to your webcam.

3

Pick Capturia and talk

Select it in Zoom, Meet, or Slack like any camera. Say your numbers, your names, your point, and the graphics land on your live feed while you speak.

First run walks you through all of it: Capturia offers to move itself into Applications, files the camera extension request, and points you at the exact System Settings switch. Upgrades never re-ask. And if you want to try it with zero installs first, the browser demo runs the same overlays right now.

Deck priming

Drop your deck. Your numbers stand by.

Give Capturia your PDF once. It arms a cue card for every figure, so when you mention your churn, the exact number from your deck lands on screen. Deck-primed cards render your file's values, not the model's guesses.

Net churn

Your figure, from your page, the moment you say it

By voice

Cards fire mid-sentence.

Capturia does not wait for you to finish. On macOS 26, Apple’s streaming speech engine matches the cue while the words are still leaving your mouth. On macOS 13 to 15, the card lands at your next breath.

In silence

Or fire them without a word.

Muted, or someone else has the floor? ⌘⌥1 through ⌘⌥9 fires the first nine cards on the rail and ⌘⌥→ walks the whole rail in order, from inside Zoom, without Capturia focused. Clear the deck and the shortcuts release.

What it can put on screen

A whole control room, on your voice.

These are live, the same components the app renders over your camera. Every one is sized to stay legible after your meeting app compresses the video.

Your numbers

Traction, growth, and milestones, animated the instant you say them.

Your audience votes. Your camera shows the count.

Say “let’s put it to a vote” and a QR code renders on your feed. Viewers scan it with their phones, tap an answer, and the tally climbs live on camera while you keep talking.

  • Nothing for your audience to install or sign up for
  • No second-screen setup, the QR lives on your camera
  • Results render on your feed, so every eye stays on you

Privacy

Private by architecture, not by promise.

You are on camera in rooms that matter. Here is exactly where your data goes, verifiable in the source.

Speech

Your voice never leaves your Mac

Transcription is on-device: Apple's speech engine on macOS 26, a local Whisper model before that. No bot joins your meeting and nothing is recorded. Only the transcribed command, and the deck you choose to load, go to your own AI provider.

Keys

Your key stays in the Keychain

Bring your own AI key and it is encrypted on your Mac with a key held in the macOS Keychain. It travels to your model provider and nowhere else. There is no Capturia account and no Capturia server holding your credentials.

Camera

The camera light tells the truth

Capturia reads your webcam through the same system camera APIs as every other app, so the light next to your lens is on whenever Capturia can see you. No light, no video. It is open source, so you can check.

The one thing the app does send: an anonymous launch ping, four fields (a random install id connected to nothing, the event name, app version, macOS version). The switch to turn it off is in Settings, and docs/telemetry.md shows the exact bytes.

Why it feels different

Built like a camera, not a plugin.

Four decisions we refuse to walk back.

Camera

Every call app at once

Capturia is a system camera, not a plugin. One install covers Zoom, Meet, Slack, Teams, and whatever your next client uses: you just pick it in the camera dropdown.

Native

Signed and notarized

A real macOS camera extension, Developer ID signed and notarized by Apple. Drag to Applications, approve once, done. No kernel hacks, no screen-share workarounds.

Truth

Real numbers only

Deck-primed figures render straight from your file, and without a deck the AI uses clearly illustrative demo numbers. Your real data comes from you, not a guess.

Legibility

Readable after compression

Meeting apps crush pixels. Every overlay holds a minimum type size and contrast floor so the far end reads it, even on a bad connection.

Use cases

Built for the people on camera.

No crew, no graphics operator, no post-production. Just you and your voice.

Founders

Pitch with proof

Say your revenue and the exact figure from your deck lands on screen. Investors watch traction happen instead of squinting at slide 14.

Teachers

Keep every eye on the lesson

Key terms, timelines, and progress appear while you explain them, and a quick vote tells you who is following along.

Sales

Demo like a broadcast

Live KPIs, a name bar with your title, and the numbers your customer cares about on cue. Every discovery call looks produced.

Community hosts

Make the room part of the show

Run polls off a QR on your feed, shout out members with lower thirds, and keep a ticker of what is coming next.

FAQ

Straight answers, on the record.

01Can I download the app today?

Yes. Download the DMG (the click starts it immediately; every build is also listed on GitHub releases), drag Capturia into Applications, and launch. Builds are Developer ID signed and notarized by Apple, so Gatekeeper opens them without warnings. The browser demo needs no download at all.

02What does it need to run?

macOS 13 or newer on Apple Silicon; the current build does not ship an Intel binary. Mid-sentence cue matching uses Apple’s streaming speech engine on macOS 26; on macOS 13 to 15 a local Whisper model transcribes instead and cue cards land at your next pause.

03How does it get into my call?

Capturia installs a macOS camera extension, so a camera named “Capturia” appears in every call app’s camera picker, right next to your webcam. Select it in Zoom, Meet, Slack, or Teams and your audience sees your camera with the live graphics on it. Prefer not to install the extension? The OBS bridge documented in the repo still works.

04Does it record my calls?

No. Speech is transcribed on your Mac and your call audio never leaves it. No bot joins the meeting, nothing is recorded, nothing is stored by Capturia. Your transcribed commands, and the deck you load, go only to your own AI provider to decide what to render.

05What does free actually cost?

Capturia itself is free forever and open source under MIT. You bring your own AI key, encrypted on your Mac with a key held in the macOS Keychain and never sent to our servers, and you pay your model provider directly for what you use.

06Which call apps does it work with?

Any app that lets you pick a camera: Zoom, Meet, Slack, Teams, Webex, Discord, OBS itself. If it has a camera dropdown, Capturia is in it.
