How it works

Record, tweak, export.
That's the whole workflow.

Record as normal

DemoThat logs your cursor and every click alongside the video. Nothing changes about how you work.

Clicks become zoom regions

Each click turns into a region on the timeline. Drag the edges to retime the camera, or delete the ones you do not want.

Polish the frame

Background, padding, corner radius and shadow — then save the look as a preset for the next video.

Capabilities

Everything a demo
needs to look pro

No keyframing, no staging, no re-recording. Record once, ship everywhere.

LIVE CLICK ACTIVITY t+0.6s

Camera follows clicks

Every click becomes a smooth pan and zoom — no keyframes to place, no easing curves to tweak.

EXPORT

Cloud upscaling to 8K

GPU upscaling when local export is not enough. Pay per frame, cancel any time.

CAPTIONS

Captions, cleaned up

Transcribe the audio and drop the filler words — no more cutting “um” by hand.

ASPECT RATIO

One recording, every ratio

16:9, 9:16 and 1:1 with a single click. Zoom regions follow the frame.

PUBLISH

Publish or embed

Turn a finished clip into a landing page or an embed link through the cloud.

By the numbers

Small app,
no fine print

No subscriptions, no accounts, no dark patterns. Just a recorder that edits as it goes.

Regions start just before the click and ease out after it, so viewers see where you are heading before you get there.

Cinematic 3D camera

One recording,
viewed in true 3D

Dolly, pan, orbit or breathe — the recording becomes a plane in real 3D space, rendered with true perspective. Adjust position, scale, rotation and perspective, pick a spring easing, and save the move as a preset.

Aspect ratios

Record once, then reframe it
for YouTube, Shorts, or a square post.

Switch between 16:9, 9:16 and 1:1 with one click. The zoom regions follow the frame, so the action stays in view in a vertical short as well as a wide tutorial.

Send a finished video to GPU upscaling and get a sharper export back. Credits are charged for frames actually upscaled, and if you cancel halfway, the rest returns to your balance.

What users say
when the demo ships

Sample quotes from placeholder reviewers — real ones land here as people adopt the app.

“Recorded the walkthrough once and the auto-zoom did the editing. It genuinely looks like a paid editor spent an afternoon on it.”
Priya N.Content marketer
“The caption cleanup alone saved me an hour per video. No more scrubbing “um” and “like” out of the transcript.”
Diego R.Course creator
“One 16:9 recording became my YouTube video, my Reel and my square LinkedIn post. That ratio switcher is witchcraft.”
Amelie K.Social media manager
“Runs fully local, no account, no watermark. My capture of a customer bug report never left my laptop.”
Jonas M.Developer advocate

FAQ

Questions,
answered

Including the two warnings your OS will throw on first launch, and why they are there.

Q1macOS says it cannot verify DemoThat. Is it safe?

Yes — the warning appears because the app is not code signed yet, so macOS cannot confirm Apple built it. The full source is public on GitHub if you want to check what you are running. To open it anyway: right-click the app and choose Open, or after the first blocked attempt go to System Settings → Privacy & Security, scroll to Security, and choose Open Anyway next to DemoThat. Until builds are signed, expect this warning on every update.

Q2Windows shows a SmartScreen warning when I install.

Same story — the installer is not code signed yet, so Windows flags it as unrecognised. The source for the exact build you downloaded is public. To install: if your browser blocks the download, choose Keep; if SmartScreen appears, choose More info, then Run anyway. A signed installer is on the roadmap.

Q3What is a credit?

One credit pays for one frame of cloud upscaling — nothing more, nothing recurring. A Pro license includes 1,800 credits, roughly 30 seconds of 60 fps footage. Credits are reserved when a job starts and settled per frame actually upscaled; cancel a job and the unused portion returns to your balance.

Q4Is it really free? What is the catch?

No catch. The recorder and editor are free and GPL-3.0: capturing, auto-zoom, captions, styling and local export cost nothing and never will. The only paid feature is optional cloud upscaling to 4K and 8K, which runs on servers that cost money to operate.

Q5Does recording need an account or an internet connection?

No. Recording, editing and export all happen on your machine, with nothing sent anywhere. An account and the cloud only matter for the features that need a server: upscaling, publishing a clip, and activating Pro.

Q6I am on Linux. Does Wayland work?

Yes — both X11 and Wayland work. Wayland capture uses the desktop portal, so you need xdg-desktop-portal and PipeWire installed (default on recent GNOME, KDE and Sway). Make the AppImage executable with chmod +x and run it.
