Every prompt public, next to its output
Pick what you're building and where it runs — the questions adapt. Everything you fill in becomes the idea text, still editable before generating.
Or try one of these
A habit tracker with streaks and a weekly calendar
A recipe box for my grandma with very big buttons
A pocket-money app for kids with chores and rewards
A study planner with a Pomodoro timer and subjects
A simple expense tracker with categories and a monthly chart
A plant-care app that reminds me when to water each plant
A workout log for the gym with sets, reps and progress
A book club app with a reading list and discussion threads
Sandboxed concept demo: it can't reach the internet or save data. Refreshing resets it — that's expected.
Build it for real
A build brief written from your prototype — features, screens, data model, rules, a recommended stack and milestones — plus kickoff prompts for Claude Code, Codex, Cursor, Gemini CLI and prompt-to-app tools. Hand it to an AI coding agent or a developer and get the real app.

How it works
1. Describe
One sentence is enough — “a chores app for my kids with rewards”. Pick phone, tablet, laptop or desktop.
2. Generate
Google Gemini writes a complete, clickable prototype — or a playable 2D/3D game — right in your browser with your own free API key. Change anything with a sentence.
3. Share & remix
Publish to get a link people can open on any device, collect reactions and comments, and let others remix your idea. Your prompt stays visible next to the result — that's how everyone learns.
