About Clank Cut
Clank Cut is a macOS application that records and edits product demo videos using an AI agent. Users queue recording jobs by providing a target URL and a flow description. The AI agent then drives a browser bundled with the app to perform the described actions, recording the process automatically. The resulting capture is processed into a polished demo video with features like auto-zoom on cursor movements, smoothed motion, and wallpaper framing. The built-in editor allows further refinements such as trimming, splitting, adjusting zoom regions, regenerating narration, and restyling cursor effects. AI narration is generated from the recorded actions and remains synchronized with the video. Background music is also added and automatically adjusted to fit the timeline. Recordings are exported as crisp MP4 files suitable for sharing on platforms like Slack, Notion, or YouTube. The application operates within an isolated browser environment, ensuring no access to the user’s files, other apps, or personal browser sessions.

Frequently asked questions about Clank Cut
What do I need to run Clank Cut?
Clank Cut is a macOS application, so a Mac running macOS is required. The AI demo agent operates within an isolated browser bundled with the app, so no separate browser installation is needed.
How does the AI demo mode work?
Users provide a target URL and a flow description, then the agent drives the browser to perform the described actions, recording the process automatically. The agent clicks real buttons and stops if it encounters issues.
What can the demo agent access?
The agent can only interact with the isolated browser inside the app, pointed at the specified URL. It cannot read files, open other apps, or access the user’s personal browser or logged-in sessions.
What macOS permissions does Clank Cut require?
Screen Recording permission is needed to capture the demo’s pixels, and Accessibility permission captures timestamped clicks and keys for features like auto-zoom. These must be granted manually in System Settings.
How does auto-zoom work in Clank Cut?
Auto-zoom tracks where clicks occur and smoothly adjusts the camera to those regions. The previewed zoom regions are exactly what is exported in the final video.
Can I edit recordings after they are made?
Yes. The built-in editor allows trimming, splitting, adjusting zoom regions, regenerating narration, restyling cursor effects, and modifying wallpaper framing. AI narration remains synchronized with the video.
