Turn YouTube videos into
newsletter-ready email blocks
A content block plugin for Kit's email editor. Paste a YouTube URL and get an AI-generated summary block back: thumbnail, key takeaways, CTA button. Ready to drop into your next email. No extra config.
How it works
Paste a YouTube URL
Drop any YouTube video link into the plugin config panel inside Kit's email editor.
AI watches the video
Gemini ingests the video directly via its file API. No transcript scraping, no captions required, works on any public YouTube video.
Get your email block
A polished email section appears in Kit's editor: thumbnail, 3 key takeaways, and a CTA button. Inline-styled and email-client safe.
Built for Kit's plugin system
This plugin follows Kit's content block specification. It registers as an app in the Kit App Store and appears in the email editor's block menu.
Plugin Endpoint
POST /api/plugin/render
Kit sends the creator's settings, the server returns email-safe HTML. No scripts, no iframes, all inline styles.
Settings UI
One field. That's it.
About this project
I built this as part of my application for the Senior Software Engineer, Creator Growth and Monetization role at Kit (on the Network Squad).
It's also a working example of how I use AI for prototyping and learning new platforms. I used Claude Code to research Kit's developer ecosystem, design the architecture, and build, debug, deploy, and harden the entire app — frontend, backend, custom domain, rate limiting, CORS, the whole stack — in a single focused session.
The Smart Video Block solves a real workflow for Kit creators (turn YouTube videos into newsletter blocks), but the bigger point is: this is how I get up to speed on an unfamiliar platform fast and ship working software end-to-end.
