Penmentor
A handwritten mathematics homework grading tool built on the Claude vision model. It recognizes handwritten content and provides step-level annotations and feedback, simulating the process by which a teacher grades assignments.
Timeline (last 90 days)
Penmentor is a project posted on Hacker News' Show HN section that claims to use Claude models to grade handwritten math homework.
Penmentor's Show HN post received 9 points and has no comments yet, so its popularity is not high.
Penmentor's core is calling Claude's vision model to implement grading and annotation of handwritten math content.
In the project demo, Claude can directly add annotation boxes and text on handwritten images, simulating the effect of a teacher circling and marking with a red pen.
Vision-language models are relatively sensitive to the spatial layout, superscripts and subscripts, and fraction structures of handwritten symbols, and misreading easily occurs in handwritten scenarios, which is one of the main bottlenecks in the accuracy of applications like Penmentor.
Penmentor currently does not disclose how it handles data, and there is the problem of an unclear privacy policy.
Penmentor currently appears to be at an early stage, and its feature boundaries and limitations are not yet clear.
