Why not just use ChatGPT?
Prompts guess. Rivalize knows.
15-25% of teams use AI prompts for competitive research. Here is why that approach falls short.
Real scraping, not hallucination
We scrape 40+ actual pages per competitor. AI prompts guess from training data that may be months or years out of date.
Source attribution on every claim
Every data point links to where we found it. Prompts cannot cite sources because they do not access real-time data.
Monitoring, not one-shots
Rivalize tracks changes over time and scores momentum trends. Prompts give you a snapshot that is already stale by the time you read it.
Real data, real sources, real intelligence.
