I’ve been playing around with Replit agent recently. Replit is a web-based integrated programming environment, and its agent is an AI tool that creates apps for you based on natural language prompts.
I wanted to use Replit agent to experiment with building a simple app. I gave myself 30 minutes to see what it could do.
I decided to build an app that takes the 1,000 most common Spanish words and puts them into flashcard format to vocabulary revision. The flow is: when you see a Spanish word, you guess the English translation, click on the card to reveal the English word, and mark your answer as either correct or incorrect. There is progress bar on the right-hand side that measures your results throughout the session.
I was able to build a prototype within the 30 minutes. I used a simple table of the 1,000 most common Spanish words from this website as my source data. And I wrote a prompt asking Replit agent to create a database with the 1,000 words and a simple user interface to serve my flashcards and progress bar. After a series of back and forth prompts and debugging, I arrived at this prototype.
It cost me $3.5 USD to build the prototype. Wild.
