Pick something small and real
The best first project is small enough to finish this week and real enough that you'd actually use it. A habit tracker, a landing page for your idea, a tip calculator, a simple quiz. Small and finished teaches you more than big and abandoned.
Scope it to one sentence
Before you build, write what it is in one sentence. "A page where I enter a bill total and number of people and it splits the tip." If you can't say it in a sentence, it's too big for a first build. Cut until you can.
A starter idea library
Stuck for ideas? Try one of these. Beginner: a personal links page, a countdown timer, a tip splitter, a random quote generator. Intermediate: a habit tracker with streaks, a budgeting calculator, a flashcard study app, a simple landing page with an email signup. Ambitious: a small marketplace mockup, a mini CRM, a quiz with scoring and results.
Pick one. Open the Build Studio. Describe it in a sentence. You'll have something running within minutes.
