Marksy verdict: best when you want fast draft feedback, not review queues

Clastify alternative

Marksy is the stronger choice if you want IB grading support that feels fast, repeatable, and student-first. Clastify is useful for exemplars and human review, but Marksy is built to move actual coursework across the finish line.

Clastify publicly emphasizes human examiner reviews, exemplars, and review-based feedback.
Its support pages mention subject waitlists and human marking availability, which reinforces the review-first position.
That is useful when you want a document review service, but less ideal when you want fast feedback across multiple IB drafts.

Does Clastify do anything Marksy cannot?

Clastify is attractive if you specifically want a human-reviewed service or exemplar-heavy support. Marksy wins when the goal is repeated IB draft feedback, because the experience is designed around speed, structure, and iteration.

What if I only need a single review?
