Where IdeaRoast wins
Price
$1 vs €19. That is roughly a 20x difference. For founders testing multiple ideas, or iterating on one, the cost gap matters — especially before you have any revenue.
No account needed
IdeaProof requires an account before you see anything. IdeaRoast does not. Submit your idea, pay, get your verdict. Nothing to sign up for, nothing to cancel.
Honest output
IdeaProof frames findings diplomatically. IdeaRoast does not. If your idea has a structural flaw, you will hear it directly — not buried in suggestions to "explore further."
Independent specialist agents
Four agents — Market, Tech, Finance, Timing — each with a separate mandate and live data access. They do not share context until synthesis, so you get independent failure modes, not one model agreeing with itself.
Actionable next steps
Every IdeaRoast verdict includes 3–5 specific actions to take in the next 7 days. Not "consider your go-to-market strategy" — actual next steps with real signals to watch for.
Live market data
IdeaRoast uses Exa for real-time web search during analysis. IdeaProof uses live data partially. Stale training data misses recent competitors, market shifts, and regulatory changes.
Where IdeaProof wins
IdeaProof produces a more polished output than IdeaRoast — PDF and slide exports, TAM/SAM/SOM analysis, formatted competitor maps. If you need a document that looks like a report you can walk a co-founder or early team through, IdeaProof is the better choice.
The multi-model approach (Claude + GPT-4 + Gemini cross-validating) also reduces hallucination risk on specific factual claims. If your use case involves presenting findings to others rather than making a personal build/no-build decision, IdeaProof's format serves that better.
