Doctor Built His Own App With AI & Saved $100K

Amjad Masad is the CEO of Replit, a popular platform for building apps with AI 🤖

He recently tweeted a message from a Replit user…

I’m a doctor with no coding experience at all and I’ve built in 5 days a fully functioning app for my clinic with integration into bookings system, ability to request prescriptions, a habit tracker, nutrition tracker with a built in database, a sleep tracker, a medication tracker with built in database and ai agent answering common medication questions, a workout tracker with built in 150 exercise database, a weight and BMI tracker, an ai agent with a symptom checker and a premium content and course area. 

All with beautiful transitions and matching my website.

This would’ve taken me 1–2 years to have implemented at a cost of £100–150k.

So far it’s cost me £75 with the additional usage.

I literally cannot believe it.

Goes to show how easy it has become to build software 😎

Play around with Replit for a few days and you could build apps like this for clients.

Here’s an example of someone who did just that and earned $750 💰
