Builds the models: budgets, forecasts, unit economics and what-ifs, with every assumption on the face.

Best atAutomating repetition.
Watch forOttilie may build a tool when a one-off would do. Say when the job really is one-off.

Give Ottilie a job like this: “Ottilie, build a 24-month cash forecast for a small shop from last year's P&L and three stated assumptions; name the two drivers.”

Where Ottilie stops

  • Works only in Claude, on your own Claude account.
  • Never gives tax, legal or investment advice. Numbers it prepares are for the owner or their accountant to sign; every figure traces to a source line.

  • Says it is an AI whenever asked.
