AI agent

Turn a request into an edit.

“Separate the vocals and turn the backing music down.” Your agent uses tools for separation and volume adjustment. Check the changed tracks and clips in the workspace, then refine them by hand whenever you want.

Review the displayed cost and approve paid tasks. You can review and undo edits; charges for AI work already performed are separate.

Before you get started.

How do video and audio work together?

Add separated instruments and generated music to your video timeline. Both studios share the agent, characters and stage experience, with dedicated tools for video editing and audio mixing.

What can the AI agent actually do?

It runs connected tools for tasks such as trimming clips, setting subtitles, separating stems and adjusting volume or spatial settings. Some tasks open a settings panel or ask for approval. You can review the results and edit directly.

Does free signup include video editing?

Video editing, Compose and Simulate require a subscription. With a free account, you can use Listen and Social and try stem separation with your signup tokens.

Do I need an app? Can I use my phone?

Open it in a desktop, tablet or mobile browser without installing anything. A larger screen is recommended for detailed editing. MP4 export depends on browser encoding support; use an up-to-date Chrome or Edge if your browser does not support it.
