First to Market, 3 Days After ChatGPT Launched — How Superpower ChatGPT Grew Into a 400K-User Extension and a 350K-Subscriber Newsletter ($20–30K/mo)

Background & product

Superpower ChatGPT is a Chrome extension that adds a ‘workspace’ to the web version of ChatGPT. It organizes conversations into folders, searches your history, exports chats to Markdown/PDF, pulls in community prompts, and adds pinning and bulk actions. It doesn’t change ChatGPT itself — it just thickens the usability around it.

It was built by San Francisco engineer Saeed Ezzati (@eeeziii), a solo developer with roughly a decade of full-stack experience. When ChatGPT launched on November 30, 2022, he shipped the first version just days later (December 7, 2022) — the first ChatGPT extension on the Chrome Web Store. Facing a ChatGPT that was magically smart but had no workspace, he built the features he wanted himself, at weekend scale, and put them out.

The design philosophy was simple: keep the core free forever. For about nine months he offered nearly all features for free, building a huge, loyal user base first. Only then did he add a Pro plan ($19/mo), while leaving the basics — history search, folders — free. On privacy, he touts a design that stores settings locally or via the user’s own Google account sync, with no servers run by the extension.

The other pillar is ‘Superpower Daily,’ a newsletter that spun out of the extension’s user base. Notably, his first revenue came not from the extension but from this newsletter’s sponsorships. As a daily AI-news media it grew to ~350K subscribers and became an asset earning ~$100–150K/yr via sponsorships, an ad network, and Boosts. One audience powering two revenue engines — a tool (SaaS) and a media property (newsletter) — is the core of his strength as a solo builder.

As of July 2026, the extension officially shows 400,000+ users and a 4.51★ rating (3,615 reviews) on the Chrome Web Store, at $20–30K/mo; the spin-off newsletter has ~350K subscribers. No TikTok virality and no outside funding — just the quiet compounding of ‘being first into the gap around a new platform, building an audience for free, and monetizing in two directions later.’

The repeatable playbook

1. 1The moment a new platform launches, be first — speed over polish — into the ‘workspace the official product didn’t build’ (first version shipped 3 days after ChatGPT launched)
2. 2Keep the core fully free for ~9 months to stack an audience and store reviews first; monetize only after the base exists, leaving the core free and layering advanced features into Pro ($19/mo)
3. 3Convert gathered users into an audience you own (a newsletter), and monetize fast via media sponsorships alongside the slower SaaS
4. 4Split revenue across the extension (subscription) and the newsletter (sponsorship) — one audience, two resilient engines
5. 5Foreground ‘local storage, no servers’ for sensitive data (ChatGPT conversations); make transparency a moat via high-star reviews (4.51★) and retention
6. 6Skip outside funding and TikTok virality; compound quietly through reviews, word of mouth, and in-store ranking

Deep dive

【Deep dive】The essence here is a ‘don’t build the magic yourself’ strategy: be first into the gap *around* the fastest-adopted magic in history (ChatGPT), build an audience for free, and monetize in two directions. Let’s break it down in order.

■ Being first is worth more than clever code. The first version of Superpower ChatGPT was, functionally, a weekend build — history search, folders, export. Almost no technical moat. It still won because it existed as the first ChatGPT extension on the Chrome Web Store at the exact moment ChatGPT was going viral. When millions of new ChatGPT users searched the store thinking ‘I want to organize / search this,’ Superpower was already there. A platform’s launch becomes a free, enormous funnel for the tools around it. The lesson is clear: the edge isn’t building frontier AI yourself — it’s filling the missing workspace around someone else’s frontier AI faster than anyone.

■ Nine months of ‘fully free’ to build the audience first. Saeed didn’t rush to charge. For about nine months he gave away nearly everything, stacking compounding assets first: reviews, word of mouth, and in-store ranking. Free wasn’t mere generosity — it simultaneously (1) maximized the first-mover position (frictionless adoption), (2) built the list of future paying candidates, and (3) earned high-star reviews, the ‘billboard’ that brings the next users. He monetized only after the base existed, and even then he left the core free and put only advanced features behind Pro ($19/mo) — so he could monetize without breaking existing users’ trust.

■ The first revenue was the newsletter, not the extension. This is the most reproducible decision. His first revenue came not from paywalling the extension but from sponsorships in ‘Superpower Daily,’ a newsletter he started for his user base. The audience a tool gathers — people who touch AI every day — becomes a high-value media readership. The newsletter hit a ~$150K annual run-rate within five months, grew to ~350K subscribers at a 32% open rate, and became an asset earning ~$100–150K/yr from sponsorships, an ad network, and Boosts. SaaS revenue compounds slowly, but media sponsorship revenue is fast once you have an audience. It’s a structure that double-dips ‘slow revenue (SaaS)’ and ‘fast revenue (media)’ from the same audience.

■ One audience × two revenue engines (= resilient even as a solo). What makes this work for solo builders is that revenue is split across the extension (subscription) and the newsletter (sponsorship). When the extension’s conversion is soft, media carries it, and vice versa. Against the risk of a platform (ChatGPT/Chrome) changing its rules, the audience (email subscribers) stays in his hands as his own asset. A tool can be taken away; an audience is much harder to take — and he ‘owned’ that asymmetry early via the newsletter.

■ Sell privacy as trust, not as a feature. Superpower touts a design that stores settings locally or via the user’s own Google account sync, with no servers run by the extension. For a tool handling something as sensitive as ChatGPT conversations, ‘your data never leaves your hands’ isn’t just a spec — it underpins the review score (4.51★, 3,615 reviews) and retention. Precisely because a surrounding tool is trusted less than the core (OpenAI), foregrounding transparency becomes a moat.

■ Takeaways for indie builders. Three reproducible points. (1) When the next big platform arrives (a new AI model, a new OS, a new device), be first — on speed over polish — into the ‘workspace the official product didn’t build.’ (2) Start free to stack store reviews and an audience; monetize only after the base exists, keeping the core free and layering advanced features on top. (3) Always convert gathered users into an audience *you* own (email), and run a two-legged SaaS-plus-media model. Even without flashy virality, this quiet compounding is within a single person’s reach.
