AI Storyboard Generator

Describe a science/medical topic in one prompt and generate a single 16:9 illustration laid out as a multi-panel storyboard grid. Useful for teaching sequences, lab protocols, mechanisms of action, or any process that unfolds step by step.

How it works

  1. Describe the full sequence in the prompt, e.g. “The stages of mitosis” or “How vaccines train the immune system.”
  2. Choose your grid — 1 to 3 rows and 3 to 6 cells per row.
  3. Click Generate Storyboard. One 16:9 image is generated with all panels laid out left to right, top to bottom.
  4. Download the storyboard once it's ready.

Tips for better storyboards

  • Write your prompt as a sequence of steps, not just a single subject — list what should happen across each panel in order.
  • Mention recurring visual details (colors, labels, setting) in the prompt to help keep the style consistent across panels.
  • Think of the grid as a beginning-to-end sequence, reading left to right and wrapping to the next row.

FAQ

Is the storyboard generator free to use?+

Yes. No sign-up or credits required — just enter a prompt and generate.

What kind of topics work well?+

Any process that unfolds in steps: biological processes (mitosis, the water cycle), mechanisms of action (how vaccines work, how a drug is metabolized), lab procedures, or physics demonstrations. Describe the sequence of steps in your prompt.

How many panels does the storyboard have?+

You choose: 1–3 rows and 3–6 cells per row, generated as a single 16:9 image with up to 18 panels total.

Is this one image or separate images per panel?+

One image. The whole grid is generated together in a single request, which keeps the illustration style consistent across panels instead of stitching together separate generations.

Can I download the storyboard?+

Yes, use the download button on the generated image to save it as a PNG.

Can I edit the storyboard after it's generated?+

Not directly from this tool, but you can open the image in the full Natomy generator to refine it with additional instructions.
