Step-by-step guides with copy-ready prompts for ChatGPT, Claude and Gemini, plus example results, practice files and a checklist before you share anything.
Open a blank sheet, ask Gemini to build it as a canvas, and get a family finance dashboard with an input table, charts, budget tracking and savings. The exact prompt, a full version, and follow-ups.
The full layout checklist: start with a wireframe, pick one hero chart, group, space, simplify, guide the eye, and leave room for insight. Every rule has a before and after.
Tell ChatGPT what you track, the KPIs you need, and the look you want. It builds the structure, formulas, charts, and dashboard; you test it and own it.
