A ChatGPT browser extension that turns user-requested workflow improvements into a paid product.
A free extension built for ChatGPT users found distribution by listening in their communities and shipping the requested feature.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Saeed Ezzati, a software engineer, built Superpower ChatGPT as a browser extension adding features to ChatGPT. He started about a year and a half before the interview, learning extension development and launching an initial version in two or three days. The first version had two features and was built in JavaScript, HTML, and CSS. Ezzati reported approximately $20,000–$30,000 MRR, 260,000–270,000 downloads, and about 150,000 weekly active users. The extension stayed free for its first nine months, while he also started a newsletter that earned sponsorship revenue within a week or two of listing it on sponsor platforms. Later, he charged for additional extension features while keeping the original capabilities free. Growth came organically through Reddit, social sharing, reviews, and community conversations. The business benefits from platform distribution but carries dependency risk because OpenAI can change ChatGPT.
For a browser extension serving a large platform, the first customers are usually users already gathered around that platform’s communities. Ezzati found potential users in subreddits, Discord channels, Slack groups, and Facebook groups, then listened for repeated requests.

The host presents the case study, but the transcript does not describe third-party verification or audited financial records; the top-line figures are founder-reported.
For an extension, the first dollar can come from an adjacent audience before the extension itself is paid. Ezzati kept all extension features free for roughly nine months, then began a newsletter three or four months after starting.
The extension’s growth loop connected free utility, user feedback, product updates, and community sharing. Ezzati said users found the extension organically, used its features, and wrote or shared reviews and “top extensions” lists without payment.
An extension can have a long stretch of free usage before it proves willingness to pay. Superpower ChatGPT stayed free for about nine months, and the founder later said he wished he had monetized earlier.
