Get your startup idea roasted before the market does — free, instant, no login
Share your idea in even one messy sentence and get honest AI feedback in under a minute.
Choose from a Brutally Honest Friend, Overly Supportive Advisor, Professional Advisor or no-mercy Roast Mode to hear your idea from different angles.
No sign-up required, and the site states ideas are not saved, so you can test sensitive concepts freely.
Optionally have your results emailed to you so you can review the feedback later.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
