Turn a screen recording into a demo people actually watch

DemoReel is a screen recorder and editor that runs in a browser tab. You record, add zooms, captions and music on a timeline, and export an MP4 up to 4K. Nothing gets installed, and nothing you record leaves your machine.

How it works

The whole job happens in one tab

Recording, editing and export, with no account and no render queue.

01 / RECORD

Capture screen, camera & mic

Pick a screen, window or tab. A countdown gives you a beat, and the take doesn't need to be clean, because mistakes get cut on the timeline.

02 / POLISH

Zooms, captions, scene

Auto-zoom scans the take and places zooms where things happened. Captions come from a speech model on your machine. Every edit is an object you can drag.

03 / EXPORT

MP4 for every platform

Encoded locally, up to 4K at 60fps. The same project exports 16:9 for YouTube, 9:16 for Reels, or any size you type in.

Inside the editor

What you get to work with

The lens drifting over the preview above is not a video effect. It's the app's glass layer, running its real shader on this page.

Cinematic zooms & auto-zoom

Eased punch-ins you place with one click. Auto-zoom scans the recording and places them for you, and you drag or delete whatever it got wrong.

How auto-zoom works →

On-device captions

A speech model runs on your own hardware, so the audio never leaves it. Captions are styled, timed and burned into the export.

About private captions →

Privacy blur & liquid glass

Blur regions stay locked to the content underneath, even while a zoom moves it. The glass magnifier is for fine print.

Blurring sensitive info →

Music & audio control

One background track with fades and looping, plus sections that duck the recording's own sound while you talk over it.

Adding a music bed →

Camera bubble

Screen and webcam record together. You move and resize the bubble after the take, once you can see what it covers.

Screen + webcam guide →

Scenes & every canvas

Backgrounds, frames and padding around the recording. Canvas from 16:9 to a custom size you type in, exported up to 4K. One project can export for YouTube, Reels and your landing page without re-editing.

Nothing leaves this device

Your footage stays on your machine.

Cloud recorders upload your footage before you've made a single edit. DemoReel does the recording, the editing, the caption model and the MP4 encoding inside your browser, on your hardware. There is no upload step to trust us about: load the page, cut your network, and everything still works.

FAQ

Questions

Is DemoReel really free?

Yes. The free plan is the complete editor: recording, trimming, zooms, auto-zoom, captions, blur, the camera bubble and every canvas shape, exporting at up to 1080p and 30fps with a small watermark. Pro removes the watermark and unlocks 4K, 60fps, music, image layers, liquid glass, custom sizes and project files.

Does my recording get uploaded anywhere?

No. Recording, editing, caption generation and export all run locally in your browser. Your footage never touches a server, and the app keeps working if you go offline after loading it.

Which browsers work?

Chrome, Edge and other Chromium browsers work best, including tab and system audio capture. Safari is fully supported. Firefox can record, but export depends on its WebCodecs H.264 support.

How do the captions work?

A speech-recognition model runs on your own device, so your audio is never sent anywhere. Captions come back with word-level timing, you fix any product names in the transcript, and they're burned into the export so they show up on every platform. English is supported today.

Can I use my license on multiple computers?

A Pro license activates on up to 3 devices, and you can free a slot yourself anytime. The free plan needs no account at all.

What exports do I get?

Standard MP4 (H.264) at 720p, 1080p or 4K, 30 or 60fps, in 16:9, 9:16, 1:1, 4:3, 16:10 or any custom pixel size. One project can export for YouTube, Reels and your landing page.
