Do I need to understand the Business Model Canvas framework before using this?
Not at all — the GPT walks you through each of the nine building blocks with plain-language explanations and concrete prompts. It will ask you questions like 'Who are the people or organisations that would pay to solve this problem?' instead of throwing the term 'Customer Segments' at you and expecting you to figure it out. By the time you finish your first canvas, you will have absorbed the framework naturally rather than through a textbook. That said, if you already know the canvas well, you can skip the tutorial-style prompts and jump straight into rigorous box-by-box iteration.
