What is Chrome Extension Builder?

Chrome Extension Builder, built by PlugThis.ai, is an AI-powered tool that converts a plain English description into a fully working Manifest v3 Chrome extension in under two minutes. No coding is required—the platform generates real code, including popup scripts, backend logic, and everything needed for the Chrome Web Store. Users simply describe what they want, and PlugThis delivers a downloadable, installable extension folder. It’s designed for rapid prototyping and shipping, not just wireframes or prototypes.

Describe your extension in natural language—"I need an extension that tracks email opens and shows me a dashboard with analytics"—and PlugThis builds it.
Real backend support
Connect your Supabase account, and PlugThis writes backend code for user login, databases, and server logic—not just a UI toy.

Users like Chetan Giridhar, founder of Indexly, have used it to build and ship extensions in a day.

How to use Chrome Extension Builder?

Go to the PlugThis.ai website and describe your extension in plain English (e.g., "Build me an extension that extracts leads from Sales Navigator into a CSV").
PlugThis generates a complete extension—popup, scripts, backend, and assets—in under two minutes.

Load the folder into Chrome via the Extensions page (enable Developer mode, then "Load unpacked").
Use it immediately; for backend or AI features, connect your Supabase account or API key as prompted.

Effect review

Chrome Extension Builder delivers on its promise of turning plain English into a working extension in minutes, as demonstrated by real user Chetan Giridhar, who built and shipped Indexly Vault and Reddit Responder in a day each. The platform’s strength lies in its complete architecture—real backends via Supabase, AI integration, and full code ownership—making it far more than a UI generator. For non-developers, it removes the weeks of dev time typically required, while developers can use it to rapidly prototype and iterate. The included prompt library lowers the barrier to entry, and the lack of vendor lock-in ensures users retain control of their code. Overall, it’s a practical, no-nonsense solution for anyone needing to ship a Chrome extension fast.
