Ask an AI to "give me feature ideas" for your product and you will get the same list every time: automation, a recommender, a reminder system, a dashboard. These AI prompts for indie hackers are built for the solo founder, indie developer, or lone PM/designer who does not have a team to push back on that list, so the prompt does it instead: pulling your actual product state, users, and constraints before it generates anything.
The ideation is deliberately wide first (a real diverge step tied to actual user pain, not generic feature tropes), then it plays the design partner you do not have and cuts the list down to what is genuinely worth building next. Works with ChatGPT, Claude, and Gemini.
