A clear, front-facing photo of the person Choose photo

Extra instructions (optional)

I have consent from the people in the video and the photo (or it's me). The result will carry an “AI” label.

Edit with a prompt

Describe what to change and AI re-renders the video.

Prompt

AI processes the trimmed part of the selected clip (3–10 s). When it's ready, the result is added to the timeline as a new clip.

Translate speech

Listens to what is said in the selected clip, translates it, and adds subtitles, a dubbed voice, or both.

FREE

It runs in your browser, nothing is uploaded. The first time it downloads a speech model (80 MB–1.5 GB) and a translation model (about 600 MB) once, then they are saved in the browser.

Spoken language

Choosing it gives a better translation: the speech is written down in its own language and translated once, instead of through English.

Accuracy

Max is the most accurate free speech model and understands accents best. It downloads about 1–1.5 GB once and is fastest on a computer with a graphics chip (any recent Mac).

Screen and camera recorder

FREE

Records your screen with sound, and your camera in a corner, in one video. Nothing is uploaded.

What to record

This phone or browser can't record the screen, so the camera is recorded. Screen recording works on a computer in Chrome, Edge, Firefox or Safari.

Microphone (your voice) Computer sound (tick “Share audio” when the browser asks)
