FAQ

Can't I just prompt ChatGPT to be critical?

You can ask, but RLHF training makes ChatGPT structurally optimistic. Studies show it rates 90%+ of business ideas as 'viable' regardless of merit. BizChecker runs a dedicated Devil's Advocate model in a separate context — it has no memory of your other models' positive feedback, so it can't be anchored by it.

Is BizChecker just ChatGPT with a different prompt?

No. BizChecker runs 6 separate models (Claude Opus, GPT-5, Grok-4, Gemini, Perplexity) each in their own context, plus a real-time Perplexity web search for live competitor data. The models argue with each other. ChatGPT is one model, one context, no live data.

How much does BizChecker AI cost vs ChatGPT?

ChatGPT is free (Plus is $20/mo). BizChecker AI is $39 one-time per report. If ChatGPT's answer leads you to spend 3 months on a doomed idea, the 'free' tool cost you far more than $39.

How long does a BizChecker report take?

~5 minutes to generate (6 models run in parallel). The report is a structured HTML page with 8 sections: market analysis, competitor map, financial model, hypothesis table, kill criteria, and GO/NO-GO verdict.
