I built a tool that turns diagrams into something blind students can touch. Here's what broke.

Description and use

<p>Last weekend I did a hackathon (Banana Hacks 2026, an image AI hackathon). I wanted to build something that actually helps someone, not just another image generator.</p> <p>So I built a tool called <strong>TouchSight</strong>. You give it any diagram, like a heart from a biology textbook, and it gives back three things:</p> <ul> <li>a <strong>tactile sheet</strong> you print on swell paper. The black lines puff up so you can feel them, and the labels are real Braille</li> <li>a <strong>3D model</strong> you can spin, tap to hear each part, or 3D print</li> <li>an <strong>explore mode</stron
