- An AI Council read across up to eight perspectives — value, macro, quantitative, and momentum lenses — that shows where they disagree instead of averaging the tension away.
- Figures come straight from FMP and Yahoo Finance filings data. The AI writes the narrative around the numbers — it never edits the numbers.
