There's a class of AI prompts that don't fit in a text box.

Not because the ideas are too long — you can always write more. The problem is that the structure of what you want to communicate is inherently visual. You're describing a flow. You're pointing at an image. You're listing constraints that apply to some parts of the context but not others. You're trying to give the AI a briefing, not a paragraph.

The text box forces everything into one dimension. And the AI, however capable, has to reconstruct the structure you had in your head from a flat string of text.

PromptBoard solves this by flipping the approach: you build the prompt visually first, then export it.
