How teams use it in Excel.
Model building, checking, and scenario work stay inside Excel while the user retains step-by-step control.
Build
Create a working model from a research thread or an instruction. Sibel writes formulas, fills ranges, and sets up the structure.
Built for controlled spreadsheet work.
The add-in keeps spreadsheet actions inspectable at the level analysts actually care about: cells, ranges, sheets, and outputs.
Staged actions
Every proposed spreadsheet change is visible before it runs. Nothing is applied silently.
Sheet-level control
Formula, range, and worksheet actions are proposed explicitly so destructive changes stay reviewable.
Connected to the research
Sheets stay linked to the Sibel workspace that produced the underlying analysis and assumptions.
