There are more document types than any picker can hold — a co-op restructuring memo, a school expansion case, a farm succession plan. The moment a tool forces one of those into a generic business-plan template, the reader can tell.
Two doors, one engine
Pick a card when a known type fits — funding, feasibility, operational, marketing, growth, tactical. Otherwise describe what you need in a sentence or two and the engine designs a bespoke outline: sections, order, and what each one has to prove. You see the outline before anything is written.
The 'What gets written' preview is not decoration. Rearranging or cutting a section there is far cheaper than editing it later.
Say who is reading it
The single highest-leverage input is the reader and the decision they must make. A document written for a credit officer and one written for a co-founder share facts and share nothing else.
Put this to work on your own venture
Describe the business once and the engine researches, drafts and scores the document — then tells you what changed when you come back to it.
