Give Me a Vibe

One button for people who don’t know what to build

Press one giant button and Gemini invents something for you to vibe-code — then a deliberately anti-sycophantic verdict explains why it’s a terrible product but an exceptional weekend project.

There is no input box, no account, and no history. You pick one of four moods — Useful, Weird, Absurd, Satirical — and the model does the rest: a titled concept with its own dynamically chosen sections, metadata tags, and a verdict that refuses to call every idea amazing. Randomness comes from the model itself, a fresh seed and rotating variation lens per request, not a hardcoded list of ideas.

Four vibe modes — the mode materially changes generation and tone, not just styling
Dynamic sections — the model picks its own structure per idea, from audience to technical spine
Honest verdicts — a good idea and a good business are judged separately
Build prompts — an opt-in second call turns a surviving idea into instructions for your coding agent
