I built 3 functional web apps in 4min… on my phone! #replit
The host demonstrates using Replit Agent on a mobile phone to build and deploy three functional web applications in four minutes. The video shows how the AI agent plans features, installs dependencies, writes code, and deploys each project automatically. The showcased applications include a Future You story generator, an electric vehicle versus internal combustion engine cost comparison calculator, and an Estonian Wordle clone.

Creating the Future You app with Replit Agent
The host introduces Replit Agent and prompts it to build a web app that predicts a user's future based on their current life.
How Replit Agent sets up and deploys projects
The presenter explains how Replit Agent plans features, installs dependencies like Flask and OpenAI, writes code, and handles deployment automatically.
Testing the Future You and EV comparison apps
The host tests the generated Future You interface and then demonstrates an EV versus ICE vehicle cost comparison calculator.
Estonian Wordle and wrapping up
The host highlights a custom Estonian Wordle clone he built on his phone and invites viewers to share what they would create.

I built a web app in 4 minutes and 2 seconds, or should I say Replit Agent built it? I came up with an idea for a website where AI predicts your future based on your current situation. Sounds crazy, but watch this. You enter the idea in Replit, an agent comes to life to propose a plan of action and additional features, and gets to build it for you. When previous AI agents either helped you write or review code, Replit Agent takes over everything from setting up the development environment, installing necessary dependencies and tools, configuring databases, generating code and then deploying it in their servers.
Also, the user interface was automatically created for easy input where I could enter my name, age, occupation, interest, and output my future vision. I then built the calculator app for comparing EV versus ICE car total cost of ownership, where you can enter the cost of fuel, insurance, efficiency, and see a graph. Yes, EVs are cheaper. As well as a Wordle game, but in Estonian, so my parents could also play, going back and forth to make sure it looks good on mobile. And should I release any of these apps?
