◇ Could this help me?
Yes. Spec-first discipline reliably improves AI-built software, and this is a usefully lightweight version of the same plan-before-build principle as GitHub's spec-kit (row 78) with one genuinely sharp addition: models regress toward the average of their training data, so an explicit differentiation doc is a real countermeasure to same-looking AI apps, not just branding advice. Prompt-only, zero risk, and general practice for any new build project rather than project-specific.
Before writing any code for this app idea, work with me to produce three short documents. Doc 1, product and tech spec: what we are building, who it is for, and why it deserves to exist. Doc 2, stack definition: platform, language, frameworks, and APIs; propose sensible defaults but record every choice explicitly. Doc 3, lock decisions: interview me about where this product deliberately diverges from the average version of this app (design, features, tone, audience), then lock each decision with a one-line rationale. Keep each doc under a page and do not start building until all three are approved. The app idea is:
