Numeric guardrails on AI narratives: how Fin4Sight prevents hallucinated KPIs

AI is good at writing a fluent summary and bad at being trusted with a number. So Fin4Sight never lets the model invent figures.

Every figure in a generated narrative is checked against the underlying source data. If a number doesn't reconcile within tolerance, the narrative is rejected and regenerated — it never reaches the user.

The narrative is the AI's job; the numbers are the data's job. Keeping those separate is what makes the output safe to put in front of a CFO.
