Open a saved Feasly project in ChatGPT, create a development or investment case, or bring a supported model file. Your assumptions and scenarios stay connected to your Feasly workspace.
Ask the question that matters
Understand what drives the result. Change a construction assumption or an acquisition input. The Feasly Calculation Engine calculates the case, so the conversation connects to the financial model.
Keep the work moving
Save the alternative as a separate scenario and open it in Feasly. Your team can review the result without rebuilding the case from a chat transcript.

Feasly runs the model.
Your saved model is the starting point. You choose the assumptions, authorise changes and review the result. ChatGPT uses Feasly’s tools to carry out your request; the Feasly Calculation Engine calculates the financial result.
Those calculations follow defined financial rules, with results you can repeat and review. Save the alternative, reopen it and inspect the assumptions behind the result.
Start from a saved case or a supported EstateMaster development or ARGUS Enterprise underwriting file. Compatibility depends on the model; arbitrary Excel conversion and native ARGUS Developer import are not included.
