Penmentor uses Claude to grade handwritten math work

Original: Show HN: Penmentor – Claude marks up your handwritten math like a teacher

Developer Abdullah Alhariri has launched Penmentor, an open-source tool that uses Anthropic's Claude to review handwritten math work and mark it up with feedback, the way a teacher would. The project was shared on Hacker News, drawing modest attention from the community. Users can submit photos or scans of their work and receive annotations pointing out mistakes and suggesting corrections.

Why now: The tool showcases a practical, novel use of AI vision models in education, which interests the developer community.
