Take apart a competitor
Learn from what exists before rebuilding it worse.
I'm building <my thing>. An existing tool doing something similar is <name / description / paste their landing page>. Analyse it: - What job is it doing, in their words and in plain words? - Who is it clearly for, and who is it clearly not for? - What does their pricing tell me about their customer? - What's conspicuously missing or obviously bad? Then honestly: given they exist, why would anyone use mine? If the answer is weak, say so and suggest where a genuine gap might be — an audience, a price point, or a simplification.
Ask for the sceptical answer. "There's room for both" is the comfortable response and is often not true; better to find out now.
