Describe the flow. It drives, records, and cuts the video. Or record your own screen and let the editor do the zooming.

Point it at your web app, give it one sentence, and it drives Chrome itself. The agent reads your page through its accessibility tree — it clicks the actual “Sign in” button, not coordinates.

what the editor already knows
01 / auto-zoom
The camera zooms to your clicks — not motion guessed from pixels. A physically-simulated spring drives every push-in, so it settles like an operator instead of snapping like a keyframe.
02 / cursor
On a macOS screen recording, the pointer path is smoothed from the timestamped input track and every click lands a ripple. The video and the event track are captured side by side.
03 / narration
The voiceover is written from the execution trace and attaches to steps, not timestamps. Cut a clip and the narration goes with it.
04 / presenter
Add an AI presenter bubble over the frame. Add AI background music. It ducks itself under the narration so nobody has to draw a volume envelope.
05 / takes
Re-run the flow, keep the old cut. Takes stack under the same video, so picking the one that landed is a click and not a file-naming exercise.
06 / durability
Queued, leased, retried. Quit mid-run and the work is still in the queue when you come back — nothing lives only in a window that is still open.
how it works
01
Hit record in the macOS app and drive the product yourself, or hand the agent a URL and one sentence: “sign in, create a project, export a clip.”
02
60 fps video plus a timestamped input-event track. The agent lane drives Chrome through the accessibility tree and produces the same two artifacts.
03
Auto-zoom from real clicks, wallpaper framing, narration bound to steps, music ducked underneath. Export MP4 and send it.
agent-native
One install drops in the CLI and an agent skill, so the thing that shipped the feature can also file the demo for it. Jobs survive the app closing — queued, leased, retried.

queued · leased · take lands in the editorA Mac. Clank Cut is a macOS app, and the AI demo agent drives web apps in stock Google Chrome.
Point it at a URL and describe the flow in a sentence. The agent drives Chrome itself — reading the page's accessibility tree, not guessing at pixels — records the run, and the take lands in a project like any other recording. If it gets stuck, it stops and tells you instead of guessing.
Every recording carries a timestamped input-event track. Your clicks cluster into zoom regions, and a spring-simulated camera moves between them — the export is exactly what you previewed, frame for frame.
Yes. Trim, split, re-speed, adjust zoom regions, swap the wallpaper framing, regenerate narration. On recordings you make yourself you can also restyle the cursor — size, smoothing, click ripples.
AI narration is written from what actually happened and anchored to steps, so cutting a clip keeps the voiceover in sync. Background music generates to fit the timeline and ducks itself under speech.
Yes — one command installs the clankcut CLI, the agent skill, and on a Mac the desktop app itself if it's missing. Recordings queue as durable jobs that survive the desktop app being closed, with retries handled for you.
An MP4 — H.264 at 60 fps with a keyframe every half-second, so scrubbing is instant anywhere you drop it.
Pay as you go, billed per organization. No subscription tiers, no seats.
Zero recording. Real demos. macOS app for the recorder, Chrome for the agent, one editor for both.
