Built on Trust. Backed by Integrity
We don't write your work. We help you perfect it
Our reviews are built for students who want to understand the criteria, not cheat it.
You'll never get templated responses or rewritten paragraphs. Just expert feedback to help you improve what you already wrote.
Your work stays private. Always
Every draft you upload for review is treated with complete confidentiality. We don't publish, share, or recycle your coursework – not as examples, not as content, not anywhere.
The exemplar essays featured in our platform come from a separate process, with full permission from the original authors.
What you submit for review will never appear publicly, and will never be used in any other product.
Committed to Academic Integrity and Equal Access
Not every student has access to top-tier teachers or private tutors. Clastify was built to level that imbalance by providing high-quality, examiner-led feedback to students at every kind of school. This isn't about shortcuts. It's about making expert support accessible to those who wouldn't otherwise have it.
Actual IB Examiners. No Tutors, No AI
AI tools, friends, and tutors can offer suggestions, but they don't have access to the examiner's lens. Clastify connects you directly to the people who have marked thousands of IB assignments and know precisely what the criteria demand. This isn't surface-level advice. It's targeted, assessment-grade insight built to raise your score.
Every review is conducted by an official IB examiner – someone who's spent years grading coursework just like yours. They've seen what earns a 7. They've seen what falls short. Now, they're here to show you the difference.
See What Happens After the Review
Grades improved. Confidence soared. Students across subjects, skill levels, and schools used the Examiner Review to transform their coursework, and their outcomes.
Browse real case studies showing what changed, how it changed, and what they scored after applying our feedback.
Still Have Questions? Ask the Examiner
Every Clastify Examiner Review includes the option to ask follow-up questions. If something's unclear or you need deeper insight, the same examiner who reviewed your work is available to help you understand the feedback and apply it with confidence.
You're not left wondering what to do next. You're supported all the way through.
Pricing
Guaranteed Quality. Or Your Money Back
If your review doesn't meet your standards, you won't pay for it.
We're confident in what we deliver because every review is built to help you score higher, faster, and with full clarity. If you receive feedback that includes a critical mistake or doesn't reflect the level of quality we promise, we'll refund you in full.
No fine print. Just our commitment to getting it right.
