Lessons from building a “paste a URL, get your brand” onboarding - our activation rate doubled when we deleted the signup wall Building an AI content tool (Sketch : turns one prompt into on-brand posts, carousels, video, etc.). Sharing one decision that changed everything, because I see SaaS founders get this wrong constantly: We let people generate before signing up. Old flow: signup → onboarding form → brand kit upload → first generation. Classic. Also classic drop-off at every step. N

Most AI learning tools explain concepts for you through summaries, notes, quizzes, and flashcards. But recognising an answer is not the same as understanding it. That’s why I built ReExplain ( for the @OpenAI Build Week Hackathon. ReExplain flips the roles - the AI becomes the curious learner, and you become the teacher. You explain the material in your own words, while the AI listens, identifies gaps, and asks follow-up questions that challenge you to think deeper. Powered by GPT-5.6 Luna and built with Codex, ReExplain is now live on Product Hunt! If the idea resonates with you, I’d really appreciate your upvote and support 😄 🔗 Product Hunt Launch Link: Watch the demo, try it, and share your feedback! #ProductHunt #OpenAI #BuildWeek #AI #EdTech #Hackathon
