ChatGPT recently announced…
a new generation of apps you can chat with, right inside ChatGPT. Developers can start building them today with the new Apps SDK, available in preview.
Greg Isenberg in a recent video…
it is possible that this becomes a big thing. And if it becomes a big thing… this is probably one of the bigger wealth creation moments in AI…
ChatGPT has 800 million weekly active users. So you can get in front of 800 million people every single week and sell them something… the discovery opportunity is huge
He goes on to share 5 apps you could build for this new app store 
- AI Tax Guy / K-1 Agent → “File my quarterly taxes”
- Healthcare Concierge → “Find the best dermatologist nearby that takes Blue Cross.”
- Credit Score Repair Copilot → “Improve my credit.”
- Make-A-Meme → “Make a meme about X.”
- AI Grandma (life advisor) → “I’m overwhelmed—what should I do?”
Greg says he’d try building such apps in Claude Code or Cursor.
How long would that take? I would say realistically two to three weeks to get something that’s working really well… you’d have to make sure that you get approved by OpenAI… maybe four weeks, in total 30 days.
