Why it was accepted

The page clearly describes a real AI-powered product with a specific workflow: it reads handwritten math, marks mistakes directly on the page, gives step-by-step hints, and can generate explanatory animations. The README includes concrete usage details, supported agents, quick start steps, and the environment it runs in, which is enough for a useful public listing.

Weakness

The snapshot does not show screenshots, a demo video, or a release history, so a visitor still cannot judge the actual UI quality or current maintenance status from the page alone.
