How to Rebuild Eightify ($500K/yr) with PlugThis in 30 Minutes (2026)
There's a Chrome extension making around $540,000 a year.
It summarizes YouTube videos with AI. It's called Eightify.
Their landing page literally says it's powered by Claude
and ChatGPT.
In this video, I'll show you exactly how to build something
like it yourself. About 5 minutes. No code. Using AI.
This isn't about cloning Eightify. They built a great
product, earned their revenue. The point is to teach you the actual playbook
so you can build YOUR profitable Chrome extension — solving
a problem you actually care about.
What you'll learn:
→ The exact prompt structure that builds Chrome extensions
→ How to handle errors (just paste them back — seriously)
→ How to add custom features in seconds
→ How to use multiple LLMs (Claude, Gemini, GPT)
→ Multi-language support, custom insight formats, and more
The real takeaway: Chrome extensions making half a million
a year are not magic. They're well-structured prompts wrapped
in a clean UI. You can build the same thing — for whatever
problem you actually want to solve.
