FREE NEW video v1.2.1 Remotion

Repo to Demo

Point it at a repo or PR and get a feature demo.

Reads a repository, pull request or diff and finds the user-facing story hidden in the code. It writes a short demo script, captures the relevant UI or terminal output, and renders a polished feature demo with callouts in both landscape and vertical formats.

Workflow

What the agent does, step by step.

01
Clone or open the repo and identify the changed files for the feature.
02
Run the app or tests to capture real interactions and output.
03
Draft a demo script that leads with the user benefit, not the diff.
04
Build annotated scenes with zoomed UI and terminal callouts.
05
Render the 16:9 master, then produce a 9:16 cut.
06
Check that no secrets or local paths appear in the frames.
