FEASIBILITY IN MINUTES. NOT MONTHS.
Build the model once. Interrogate it all day.
PlotKey keeps assumptions, monthly cash flow, returns and sensitivities in one live workbench. Explore freely; save only the revision you want to keep.
- ✓Change live assumptions with deltas against the saved draft
- ✓Compare base, upside and downside without copying tabs
- ✓Let the Operator draft changes; review before anything is accepted
From deal brief to IC decision — one workbench
Model the deal, test the downside, and carry a clear decision record into IC.
Assumptions on the left. Everything else reacts.
25+ live parameters — pricing, costs, pace, land, financing, tax — with sliders for the big levers. The KPI strip, statements and a full outputs rail recalculate as you drag, with deltas against your saved draft.
Open the workbench →An AI analyst that shows its work — and asks permission.
Ask it to stress construction +10% or draft a conservative variant. It runs the real engine and files a proposal for review. Accepted proposals update the draft; saved changes are hash-linked when you save a model revision.
See the Operator console →The workbook your lender opens is the model you built.
Supported formula identities are checked before export; failed identities are pinned to correct engine values. XIRR and iterative cells are covered by the LibreOffice oracle.
See the verification proof →Your Excel export is checked before it leaves.
Supported formula identities are checked by the recalculation gate. Failed identities are pinned to correct engine values instead of emitting a wrong formula. XIRR and iterative cells are checked by the LibreOffice oracle; saved model revisions are recorded on the hash-linked audit chain.
