comparison for students deciding between a dedicated IB feedback tool and an exemplar-and-review platform

Marksy vs Clastify

FAQ

Can Clastify replace Marksy for IB grading?

Clastify can help students find exemplar resources, but it is not a purpose-built feedback workflow. Marksy adds rubric mapping, AI detection, and structured outputs that make it easier to see what to improve.

Is Marksy more consistent than Clastify?

Yes for feedback tasks. Marksy applies the same IB-oriented workflow each time, while Clastify is primarily a resource and review platform.

What if I already use Clastify in class?

That is fine. Many students use Clastify for exemplars and Marksy for assessment feedback. They solve different problems.
