How One Developer Built a $20K/Month Chrome Extension on Top of ChatGPT

Saeed Izadi built Superpower ChatGPT, a browser extension that adds extra features to ChatGPT, entirely by himself. Within a year and a half, it reached $20,000 to $30,000 in monthly recurring revenue, with roughly 260,000 total downloads and 150,000 weekly active users. He had never built a browser extension before. He learned how in two or three days after ChatGPT launched, and the first version had only two features.

He recommends two paths: build for an existing giant platform like Gmail, YouTube, or Twitter, where even if only a tiny fraction of users want your feature, that can be enough to live on. Or build for a platform with a smaller user base but an existing marketplace, like Zoom or Salesforce, where fewer developers are competing.
