I cloned Calendly using ChatGPT Codex 5.5 and Claude AI without touching a single line of code. In this video I show you how to vibe code a full calendar booking app in 2026 with Google login, Google Calendar sync, and a Remotion video. If you want to launch a SaaS app, this is exactly how to start.

Thanks for this effort
Hi Jason, Great video. One thing I'd like to touch on, when I started there wasn't a whole lot of info on the last steps you mention. I'm not sure if you have already created a video on the full process, but I'd suggest maybe creating a video that show the full process, linking databases, Like Supabase, RevenueCat and getting the finished files/folder ready for submission. I think this would help out those who are just starting out to get a full picture of what's involved and take a lot of the guess work out, trying to find the answers to these question. Overall great video and demonstration. NICE!
hi Jason, thanks for sharing, can you demo how to build a dating app like coffee meets bagel?
thanks for marking this video
did you get the spam rejection at first? I wonder bc this category is overly saturated and I wonder how you bypassed it
Do we need a paid plan to use Codex?
Wild how AI can spin up apps in minutes, real challenge is turning code into customers.
Hey @jason, Thanks a lot. You've solve few of my problems really moved what you have done. Really really helpful.
I really cannot fathom how people can hype up Cursor AI so much. Claude isn't much better, either; both make critical errors and, even after hours, fail to fix bugs—and when they finally do, they just introduce two new ones in the process. What we really need is an AI to monitor the AI, and so on and so forth.

Its not about the product, it's all about distribution. It doesn't matter if you can copy apps, it's not worth 900k unless you've marketed it to that level.
lol okay
*This Is Not a $900K App — It’s a $900K Headline*
This is exactly the kind of clickbait that makes people distrust “AI app” content. You did not build a $900K app. You built a prototype/clone of a type of app where other companies make money, then framed the title like you personally created a revenue-generating asset.
That distinction matters.
Building a demo is useful. Misrepresenting it as a money-making app is not respectable. This kind of framing sells false expectations to beginners who don’t understand the difference between a local prototype and a real SaaS business with users, payments, retention, support, and revenue.
Now watch eveyrone make the same app and price it cheaper, and now you dont make anything.
Race to the bottom, stupid age.
its really cool can u please create astrology app
Did I miss the part where you make $900k???
Trustmrr link or this is just fake BS.
Its not an App, its prototype, such thing has 0% chance to get into App Store
Man you have earned a subscriber
yes 13 minutes, totally clickbait.
this guy need to be reported for misleading
