Winning Structures — Development skill for Claude Code

Winning Structures

**Re-create the structure of any viral video — then make it your own, refilled with your own words at the creator's exact pacing.**

**[Try it live →](https://winning-structures.vercel.app)** — browse the seed library, rewrite the beats, play the teleprompter. To analyze your own videos in the browser, connect your own API keys (Anthropic for beat-mapping, OpenAI for transcription) and upload a video file — analyses bill to your keys, which never leave your browser. The local version below additionally ingests straight from a TikTok/YouTube/Reels link.


Paste a TikTok / Reels / Shorts / YouTube link. The app downloads it, transcribes it word-by-word, and has Claude map the script into its structural beats — hook, points, money line, CTA. Open a card to rewrite the script line-by-line (it estimates your line's duration at the creator's pace) and play it back as a teleprompter while you record.

The premise: videos don't go viral because of editing — they go viral because every sentence has a job. The theory behind the beat labels lives in [docs/structure-anatomy.md](docs/structure-anatomy.md): five viral videos annotated sentence-by-sentence, the two retention engines (withhold vs. deepen), and seven laws that repeat across all of them. Worth reading even if you never run the app.

Run it

git clone https://github.com/louisedesadeleer/winning-structures
cd winning-structures
python3 server.py        # → http://localhost:8756

That's it for browsing the library and using the prompter — no dependencies, no build step (the frontend ships prebuilt in `static/`).

**To analyze new videos**, the server shells out to a few tools:

Tool	For	Install
yt-dlp	downloading the video	brew install yt-dlp / pipx install yt-dlp
ffmpeg	audio probing + thumbnails	brew install ffmpeg
Whisper	word-level tr
