One-time scoring vs ongoing research
IdeaProof is designed for a specific moment: you have an idea and want a quick assessment. It analyzes across 50+ criteria and returns a score with market sizing in about 2 minutes.
BigIdeasDB is designed for the entire research journey. Start by browsing pre-analyzed complaints, validate with cross-platform evidence, then use BuildGuide and BuildHub to plan and manage the build. It is not a one-time tool — it is an ongoing research platform.
AI estimates vs real evidence
IdeaProof's analysis is AI-generated from aggregated data sources. It provides useful directional guidance but the data points are estimates, not direct evidence.
BigIdeasDB shows you the actual complaints. When you see 200 real users describing the same frustration across G2 and Reddit, that is a different level of confidence than an AI-estimated market size.
When to use each
Use IdeaProof for a quick sanity check on a new idea before investing time in research. Use BigIdeasDB for thorough validation with real evidence and the full pipeline from research to build. Many founders use IdeaProof first, then BigIdeasDB for deeper validation.
