We already use CoPilot why use Formuly?

CoPilot and other domain specific AI solutions offer very good generalist solutions for Business Users.

Formuly is purpose-built for professional financial modelling, combining unbeatable best practice methodology with an LLM trained on 30+ years of deal-making expertise. Financial modelling for transactions goes far beyond Excel — it’s technical, nuanced, and critical. Unlike general tools like CoPilot, Formuly is designed specifically for modellers, analysts, and dealmakers.
