Build Together is a 5-question interactive quiz that drafts you a personalised 30-day build plan — for your side project, startup idea, or portfolio refresh. Default mode runs entirely client-side: zero cost, no data leaves your browser, instant results. Want a real AI-streamed plan instead? Paste your own API key (BYOK) and get a custom response. No signup. No paywall. No tracking. Just answers, actions, and a 30-day roadmap you can start tonight.
