About us
Helping IB Students Succeed for Over 5 Years
It’s no secret: writing IAs, EEs, and TOKs is difficult, unclear, and often confusing. Whether it’s your first coursework or you’ve done a few before, it can be daunting looking at a blank page and wondering what to write. To solve this problem, in 2020, Clastify’s team created a library of exemplar essays marked by official IB examiners, so that no student has to feel that way.
Since then, we’ve grown into a platform trusted by 350,000 IB students each month, supporting all aspects of IB coursework. Understanding the stress of writing coursework and the lack of consistent teacher feedback, we also introduced an Examiner Review Service, enabling you to upload your work for personalized feedback and guidance from the official IB examiners.
How does Clastify work?
Clastify is the largest and most trusted IB coursework platform online, built specifically to help students with their Internal Assessments (IAs), Extended Essays (EEs), and Theory of Knowledge (TOK) essays. Our exemplars library features the best coursework across every subject group, each one marked and annotated by official IB examiners using the official IB assessment criteria.
In addition to our exemplar library, Clastify offers an Examiner Review Service. This service connects students with official IB examiners who provide detailed, criterion-based feedback and predicted grades on their drafts - just like what they’d receive during actual IB moderation. Whether you're working on an EE, IA, or TOK essay, our examiners highlight your strengths, identify areas that need improvement, and give you concrete, actionable suggestions.
With Clastify’s Examiner Review Service, students gain the rare opportunity to see their work through the eyes of an examiner.
What makes Clastify different?
What sets Clastify apart is our exclusive focus on IB coursework. Unlike generic IB websites or AI-powered platforms, all our materials are created or reviewed by official IB examiners. We also continuously update our content to reflect the latest IB syllabus changes and assessment guidelines.
We’re not just another IB resources website. We are IB coursework experts, committed to helping students succeed with the highest-quality, examiner-backed resources available.
Feedback Straight from IB Examiners
Everything we offer, from our exemplar library to the feedback provided in our Examiner Review Service, is marked or created by experienced IB examiners. That means that every resource we provide is marked against the official IB assessment criteria, so you can be sure you're getting the best, most accurate advice available.
Other websites offer guides or examples, but none connect you directly to actual IB examiners. That leaves our materials with the unique advantage of insider information that will guarantee your coursework is up to and beyond IB standards.
Trusted by IB Students and Teachers Worldwide
Over the past five years, Clastify has supported more than 2 million IB students around the world. We are trusted not just by the students, but also among IB teachers and schools who regularly recommend and use our platform to understand the best ways to assess coursework. On average, students who use Clastify improve their coursework grades by 42% - a testament to the effectiveness of our expert resources and guidance.
Whether you're aiming for a 7 in History, struggling with your Math IA, or looking to boost your TOK score, Clastify is here to guide you. We're proud to be the go-to platform for IB students and educators worldwide.
