What is StackIndex™?

StackIndex is the proprietary scoring engine built by Site Factory LLC that powers instawhat.ai's evidence-backed rankings of AI tools. It scores AI tools across four intelligence layers — operational, trust, market, and infrastructure — and classifies AI news by credibility. StackIndex evaluates AI tools for the people choosing between them; it is not a voice-of-customer, sentiment, or consumer-feedback platform.
