What you get

Inside the Vibe Editing Kit.

The full pipeline, open source

Python code for every step, from transcript to export, on GitHub. Read it, run it, change it.

Jump cuts that never clip a word

Silence detection tuned to your voice, with a safety net that keeps every word whole.

An AI edit plan

Claude reads your transcript like an editor and decides the hook, the emphasis and where graphics go.

Word-by-word captions

Animated captions in your brand colour that step aside when a graphic is on screen.

Motion graphics as web pages

Two ready-made templates you can restyle with CSS, and the pattern to build your own.

Music and export, done

Music that dips under your voice, loudness set for social, in 9:16, 16:9, 1:1 or 4:5.

How it works

Every step an editor does, given to its own worker.

The framework from the video: write the job down as a recipe, decide which steps need thinking and which are just doing, then automate each one.

Questions

Before you grab it.

Is it really free?
Yes. The kit is open source under the MIT licence. Running it costs nothing, or a few cents per video if you add the optional AI keys.
Do I need to know how to code?
You need to be comfortable running a few commands in a terminal. The README walks through setup step by step.
Is this the same system you use?
It’s the core of it: the same recipe and the same tools, in a version small enough to read in an afternoon. Our production system adds retakes, b-roll, more templates and plain-English edits on top.
What footage does it work with?
Talking-head videos: one person speaking to camera, like ads, VSLs and social content.
