Record your demo once.
Show it in every language.

MakeDemoFast is a Chrome extension and web platform that lets you record polished product demos and distribute them internationally. Record your screen, translate the voiceover with AI, and embed the demo on your website — visitors see it in their language automatically.

After recording, your voiceover is transcribed by Whisper, translated by DeepL, and spoken by ElevenLabs in the target language. The result is a natural-sounding voiceover in any supported language — generated with one click.

We support all major languages including English, German, Spanish, French, Portuguese, Italian, Dutch, Polish, Japanese, Korean, Chinese, and many more. The AI translation pipeline handles 29+ languages.

Yes! Copy a simple embed code and paste it into any website. The embedded player auto-detects your visitor's browser language and plays the matching voiceover. Available on Creator plans and above.

Yes, you need our Chrome extension for recording. It captures high-precision mouse events, allowing us to create perfectly smooth cursor overlays. Editing, translation, and embedding are all done in the web app.

Yes! You can trim, add manual zooms, blur sensitive info, add text overlays, toggle smart zoom features, and add translated voiceovers — all in the built-in editor.

Your existing translations and embeds continue to work. You just won't be able to generate new AI voiceovers until your credits renew next billing cycle, or you upgrade to a higher plan.

Your embedded demos will continue to play for your visitors. However, you won't be able to create new embeds or generate new translations. Existing content stays live.

MakeDemoFast works in Chrome and other Chromium-based browsers (Edge, Brave, Arc). The embedded player works in all modern browsers for your viewers.
