SPARK YOUR CURIOSITYCURIOSITY FEEDS THE MIND. CREATIVITY FEEDS THE SOUL.
What are we working with today?
Start with nothing, start with what you have, or start with a wild idea. We'll find a project worth making.
Projects are AI-generated suggestions, not verified instructions. Check safety, materials and costs before starting. Save selected plans locally in Spark Lab.
No account. Privacy-friendly Plausible analytics counts visits and broad interactions; we do not send your typed questions or full map to analytics. Your exploration journey stays in this tab unless you explicitly save, download, or share it. Up to five recent questions are automatically saved on this device so you can revisit them; you can clear them from the homepage. Your Portal reads only locally saved information; it does not automatically upload your journey. Beta note: Direct answers and optional AI suggestions, reading guides, and project plans use an AI provider. When you request an AI answer, Spark sends your question; other AI features may send the selected topic, your starting curiosity and a short recent topic trail. AI-generated content may be inaccurate; verify important claims independently. Local exploration remains available without AI.
