Start with a question
Write down who your idea is for, what they are trying to do, and the smallest thing you can build to test it. Pick one main feature before adding more.
Use the tools you know
Any language or platform is welcome. A web app, mobile prototype, game engine, physical device, spreadsheet automation, or no-code workflow can all be a starting point. AI tools are optional. Follow the licenses and usage terms for every resource you use.
A simple build checklist
- Choose an idea and define a small first version.
- Sketch the main interaction.
- Build and test the essential feature.
- Ask someone to try it and note what changes.
- Record a walkthrough and write clear build notes.
- Check that your submission links work for someone else.
