A real Mac app, not a web page.
Native, fast, and built for macOS 14 and later. These are screenshots of the current build.
Pre-release build. Details may change before launch.
Record
Press one key. Just do the demo.
The HUD opens from anywhere. Pick a project type and ZumCast records your screen, camera, voice, clicks and keys, ready for every format.
Teleprompter that listens
Your script waits for you.
Read from a script that scrolls as you speak and stops when you stop. No speed to set, no losing your place, and it works offline.
On-device speech recognition. Your voice stays on your Mac.
- The HUDA launcher you open with one key.
- Project typesProduct demo, tutorial with a guide, vertical clip or bug report, each with its own preset.

Edit
Edit by talking, or by text.
Auto-zoom, a smooth cursor and captions are ready when you stop recording. Fine-tune by deleting words, drag the Angle pad, or ask Zumi.
3D angles
Zooms that lean in.
Drag the puck on the Angle pad. Each zoom can have its own angle, and “lean into the click” tilts toward the button you pressed so the eye lands on it.
- Settle, Hold or Float. Tilt on the way in, keep it, or drift slowly.
- Vary between zooms so a long video never feels repetitive.
Smart redaction
Safe to record your real dashboard.
ZumCast finds emails, API keys, cards, IBANs, IP addresses, phone numbers and faces, and blurs them for good. On video the blur follows them as the page scrolls. Prices and names are only blurred when you ask.
- Blur, pixelate or a solid bar. Burnt into every export, never just hidden.
- Found on your Mac. Nothing is uploaded to look for secrets.
