Build a multilingual typing app for language learning
A buildathon participant used Replit Agent for the first time to create LingoType, a typing app for mastering new languages.
A former programmer used Replit Agent over a weekend to build a booking app with calendar, Google OAuth, Stripe deposits and notifications, though time zones and UI needed back-and-forth.
A former programmer used Replit Agent over a weekend to build a booking app with calendar, Google OAuth, Stripe deposits and notifications, though time zones and UI needed back-and-forth.
On Thursday night he opened a blank repl and typed one paragraph asking for a Calendly-style calendar, Google OAuth, Stripe deposits and Postmark notifications. Replit Agent sketched the backend, wired Stripe, set up calendar integration and scaffolded a React front end. On Saturday he went back and forth with it on time-zone math and UI polish, and debugged in plain English.
He ended up with a working prototype: client booking, artist dashboards, onboarding, conflict handling and Postmark confirmation emails. Stripe is connected but deposits are still on the roadmap. The app hasn't launched.
The agent sometimes rewrites working code for no reason, or breaks things and claims it fixed them, so check each change.
Build a booking app for [type of small business, e.g. tattoo artists] with a calendar, Google sign-in, and deposit payments through Stripe in test mode. Include email or text notifications and handle time zones correctly. You're done when I can book a test slot end to end. Pause and show me before connecting live payments or sending any real messages.
