Is my video uploaded?

No. The video stays in your browser and is processed with local browser APIs.

Does the AI send audio to a server?

No. The speech model downloads on demand and inference runs on your device. Only static model files are fetched.

Can I use it on a phone?

Yes. The layout adapts to mobile, uses a smaller AI model on constrained devices, and lets you lower export resolution.

What is stored in a project file?

Only editable settings, captions, text, and basic source metadata. Reopening asks you to relink the original media.

A capable editor that keeps the footage with you

Adjust brightness, contrast, saturation, monochrome, sepia, and blur, or start from one of 80 editable visual templates. The preview, project settings, captions, and final render stay in this browser. Save a small project JSON and relink the original video later without placing the footage in cloud storage.

What you can do

Choose from 80 built-in layouts across eight practical categories
Crop, rotate, flip, mute, resize, and adjust the output format
Apply brightness, contrast, saturation, monochrome, sepia, and blur
Add editable text and timed subtitle tracks
Generate captions with an on-demand, device-adaptive local AI model
Export with WebCodecs using your device — no server rendering

How to use the local video studio

Import a video Choose a video directly from your device. It is opened as a local browser object, not uploaded.
Choose a layout Apply a template or set the canvas, filter, text, and caption controls yourself.
Preview and refine Play the source on the canvas, seek on the timeline, and edit every setting before rendering.
Export locally Render an MP4 or WebM with WebCodecs and save the finished file straight to your device.

Your footage stays on your device

Video decoding, preview, AI inference, and rendering run in your browser. AI runtime and model files are downloaded only when you request captions; your audio and video are not included in those model requests. Project JSON contains settings and source metadata, never the media bytes or a private local path.
