## What is See?

See-O is a minimalist perceptual training tool designed to push your visual processing to its absolute threshold.

• 6 procedural tasks (orientation, contrast, temporal) • Real-time Gabor patch stimuli • 3-down, 1-up adaptive staircase • Zero gamification or distractions • 100% on-device privacy

Customize your grid density, starting contrast, and session length. If you understand the mechanics of visual processing, you know exactly what this is built for.

Find your threshold.
