IdeaGauntlet
Stress-test product ideas with adversarial AI agents.
⚔️ Stress-test product ideas with adversarial AI agents. Court-style critique, synthetic users, web research across 4 sources, 8-type niche detection, and MVP planning — before you write a single line of code. - Thuong180702/IdeaGauntlet
I built IdeaGauntlet because I kept seeing the same problem: people, including myself, often get excited about an idea and start building too early, before really testing whether the idea is clear, painful, differentiated, or worth validating.
Most AI tools help you generate more ideas. I wanted something different: a tool that helps your existing idea survive criticism before you spend weeks building the wrong thing.
IdeaGauntlet is an open-source CLI and library that turns a raw product idea into adversarial critique, court-style multi-role debate, synthetic user objections, MVP validation plans, and side-by-side idea comparisons.
While building it, the process evolved from a simple “critique my idea” command into a more structured validation workflow:
- quick critique for fast sanity checks
- court mode for deeper multi-role debate
- synthetic users for objections and interview prep
- MVP planning with kill criteria
- benchmarking and history tracking so ideas can improve over time
The goal is not to predict whether an idea will succeed. The goal is to expose weak assumptions earlier, sharpen the idea faster, and help founders, indie hackers, and product engineers validate before they build.
I’d love feedback from the community — especially on the workflows, scoring system, and what kind of idea-validation reports would be most useful before starting a project.
The court-style framing for adversarial critique is a really clever touch. Makes the whole thing feel more like a deliberate sparring match than a generic checklist, which honestly makes me want to throw half-baked ideas at it just to watch them get dismantled.
The adversarial angle here looks genuinely useful, especially the synthetic users part. One thing that would push it further for me — letting me save and compare multiple gauntlet runs side by side so I can see how an idea evolves after I tweak the concept. Would make iteration way more tangible than starting fresh each time.
