/brag: turn the app you built into a launch video

The free, open-source skill from the reel. Run it inside your project and it reads your code, picks the best moments, writes a storyboard and renders a short launch video with music, motion and the post copy to share it.

CostFree and open source (MIT). It runs inside Claude Code (or Codex and other agents), so it uses your normal plan. The makers also run a paid web app (letsbrag.app, pay once) if you'd rather not run it yourself, you don't need it.

DoesReads your project's code, plans the story, writes the storyboard and renders brag.mp4 (about 20 seconds, landscape by default) plus share copy into a brag-output folder. Voiceover is off unless you ask for it.

NeedsClaude Code (or another agent that supports skills), Node.js 22+, FFmpeg and the Hyperframes CLI (runs with npx).

What you need first

1Claude CodeAnthropic's coding tool for your terminal, signed in with your Claude account. Codex, opencode and other agents work too.

2Node.js 22 or newerDownload it from nodejs.org. Check with node -v.

3FFmpegOn a Mac: brew install ffmpeg. Check with ffmpeg -version.

Step by step

Open your project in Claude Code

Go to the folder of the app or website you built and start Claude Code there (type claude).

Install the skill

Type /plugin marketplace add latent-spaces/brag, then /plugin install brag@brag.

Tip: Other agents: npx skills add https://github.com/latent-spaces/brag --skill brag.

Check the video engine

Run npx hyperframes doctor in your Terminal to check Node, FFmpeg and the renderer are ready.

Make the video

In Claude Code type let's /brag. Want a different feel? /brag --tone "fake Series A launch from 2016". For Reels and Shorts add --format vertical.

Grab the result

Open the brag-output folder: brag.mp4, a poster image and share-copy.txt with the post text.

The catch

Made for software projects. It reads your code, so it fits apps and websites, not a general business with no code.
You need Node.js 22+ and FFmpeg first. Without them the render step fails.
Free skill, plan usage. It runs on your Claude (or other agent) plan, and making a video uses a fair bit of it.
Landscape by default. Ask for --format vertical if it's for Reels, TikTok or Shorts.
Check the video before you post it. It writes the copy and picks the moments itself, so read the claims it makes about your product.
