Give it your own template to match, don't let it invent formatting

If your organisation already has a template for the document you're drafting - a proposal template, a policy template, a standard report layout - paste its actual structure into the prompt rather than describing the document type in general terms and hoping the output matches.

Left to its own defaults, an AI tool will format a proposal or a report in whatever shape it's seen most often in its training data - which is a perfectly reasonable generic structure, and reliably not the one your organisation actually uses. You then spend more time reformatting headings, reordering sections and renaming things to match house style than you'd have spent writing the structure yourself, which defeats most of the point of asking for a draft.

The fix is a five-second addition to any document prompt: paste the actual heading structure of a real example of that document type, even a blank one with just the section headers, and ask it to fill that structure rather than invent its own. "Use exactly these section headings, in this order" is a much stronger instruction than "format this as a proposal" - the second is asking the model to guess at a convention it can't see; the first hands it the convention directly.

This is worth doing even for a one-off document, but it pays off most on anything you're going to ask for repeatedly - save the template once, in your prompt library or wherever you're already keeping reusable prompts, and every future version of that document starts already looking like it belongs in the same folder as the last one.
