## What is Saccade?

A/B testing. With your eyes. No surveys. No clicks. No opinions. Just look at two images and your unconscious gaze picks the winner.

HOW IT WORKS
1. Upload your variants — two logos, four hero images, eight headshots. Add 2-12 images and Saccade generates every possible A/B pair.
2. Just look — each pair appears for 3-8 seconds. Your iPhone's TrueDepth camera tracks where your gaze lingers. You don't choose — your eyes do.
3. See what wins — instant ranked results with preference strength bars. Share the results card with your team, your client, or your group chat.

WHY IT WORKS
You can't fake where your eyes go. Research shows gaze duration correlates with preference — even when you know you're being tracked. It's called the gaze cascade effect, and it's been used in commercial eye-tracking studies for decades.
