The outline generator turns a topic into a logical heading structure you can write against, optimised for readers and search engines.

  1. Enter your blog post topic and target keyword.
  2. The AI proposes a title and an intro angle.
  3. It builds H2 sections with supporting H3 points.
  4. Edit the outline, then write each section.

Worked example: “Beginner houseplants” returns an intro, H2s for choosing, watering, light and troubleshooting, plus a CTA.
