VibeBlocks then processes this input to generate a spec-driven blueprint, which includes breakdowns, requirements, designs, tasks, and hooks. Once the AI builds the blueprint, you can edit or regenerate details. Finally, you can export the blueprint as Markdown or PDF, then paste or upload it into AI coding tools like Cursor or Lovable to train their AI on your exact plan.
