This generates feature ideas for a new product from three angles: PM (market fit, competitive advantage), designer (UX, onboarding), and engineer (technical implementation, integrations). You feed it a product concept and target market, and it spits out 5 ideas from each perspective, then prioritizes the top 5 overall weighted toward core value delivery and fast validation. The framework explicitly distinguishes initial discovery (is this worth building?) from continuous discovery (how do we improve what exists?), which is a useful mental model. It can pull from uploaded market research or do web searches if needed. Best for very early stage product work when you're still figuring out what the thing should even do.
