Clastify and Revision Dojo are some of the most popular platforms for IB support – but how do they stack up against each other? And more importantly, which one is the right choice for you?
Clastify vs Revision Dojo
Quality of support
Clastify
Clastify prides itself on delivering truly exceptional feedback. Every member of the team is an official IB examiner, meaning student work is not only reviewed by experts who deeply understand the curriculum, but is also assessed with the same precision and standards used in the real exams. This ensures students receive insightful, personalised, and actionable suggestions, tailored to their unique areas for growth, allowing them to achieve the highest marks possible.
Revision Dojo
Revision Dojo, on the other hand, relies heavily on AI to assist students. While this might appear ideal at first glance, especially as the platform promotes this as a major strength, claiming it offers tailored support, in practice, it can often result in inaccurate or overly generalised feedback. Many students have voiced concerns about this. For instance, one student shared: ''The entire platform is basically AI generated, all the notes, lessons, flashcards etc. The notes and lessons especially seem like they've been generated by just uploading the IB textbook onto ChatGPT or something (the structuring is the exact same) which isn't bad, but ChatGPT isn't always 100% reliable and I wouldn't trust my marks with it.'"
Verdict
AI platforms may seem appealing to some students for their flexibility, but Clastify, puts real human expertise at the forefront. Every piece of feedback is delivered by seasoned IB examiners with years of experience, ensuring student work is assessed with precision, care, and context that an online tool can't replicate. Clastify would never leave student grades to chance – or to a machine prone to errors. The firm prioritises helping every single student excel with tailored guidance.
Use of AI
Clastify
As mentioned, Clastify would never leave your work up to chance – every piece of work students submit for marking is reviewed by official IB examiners.
That said, this doesn’t mean Clastify is behind in utilising the latest technology to support student learning. In fact, Clastify is paving the way for AI-driven education with its proprietary AI tool, Clai. Unlike Revision Dojo's ChatGPT-based tool, Clastify, with the help of its machine learning team, has trained its own AI on thousands of exemplars and markschemes. This means Clastify's AI tool was designed from the ground up to provide nothing but IB-focused support. Still, Clastify stands by its commitment to never leave a student's grade up to chance. Clai is only intended as a tool for quick feedback during coursework drafting – students can submit their draft, get a few quick tips, improve, and use it again and again as they go.
Students may also submit their completed drafts for a thorough Examiner Review. Here, the submission will be reviewed by an official IB examiner – the same professionals who evaluate final exams and coursework. Students will receive tailored feedback that points out what exactly to improve, and how, in order to score top marks. To learn more about this, click here.
Revision Dojo
Revision Dojo’s AI tool, by comparison, appears to be based on a standard ChatGPT system, which tends to provide more generalised feedback and information. While useful in some contexts, such tools can occasionally offer oversimplified responses, broad generalisations, or even inconsistencies when asked similar questions at different times. Some students have also expressed that the AI-generated content does not always align closely with the IB syllabus. Furthermore, it seems that Revision Dojo’s tips and blogs may be produced using ChatGPT models, and reports from former employees suggest that the company makes extensive use of AI-generated content to reduce costs.
Verdict
When it comes to reliable IB support, Clastify stands out for its unique approach. By combining expert marking from official IB examiners with its purpose-built AI tool, Clastify ensures that students receive feedback grounded in IB standards rather than generalized advice. Clai is trained specifically on IB exemplars and markschemes, making it a focused tool for coursework drafting – not a replacement for professional marking. In contrast, Revision Dojo uses a more generic ChatGPT-based system, which may not always provide the same level of accuracy, depth, or consistency. While both platforms incorporate AI, Clastify integrates it as a support mechanism without taking any risk in compromising the quality and reliability that IB students depend on.
Clarity of support
Clastify
What also makes Clastify stand out is its user-friendly interface. Clastify doesn't rely on flashy, eye-catching elements to ‘wow’ their users. Instead, Clastify believes the most effective form of support is one that is easy to understand and implement. The website is simple to navigate, free of unnecessary elements, yet fully equipped with everything you need. The exemplars available at Clastify include annotations, grading, examiner comments, IB requirements, and a section where you can ask specific questions. Similarly, the feedback provided by the IB examiners is always precise and actionable, clearly outlining what to improve and how to achieve top marks. Furthermore, every examiner comment is reviewed by Clastify's trained AI tool to ensure clarity, and nothing is changed without a secondary quality check from another official IB examiner.
Revision Dojo
Some users have found Revision Dojo's interface to be somewhat cluttered, with feedback tools and webpage elements that can feel a bit overwhelming or difficult to navigate.
Verdict
Clastify is designed to be clear and easy to navigate, focusing on what genuinely supports students. Its straightforward layout, well-organised exemplars, and direct feedback from IB examiners help students clearly see how to improve. Some users have mentioned that Revision Dojo’s platform can feel a bit busy at times, which may make it slightly harder to focus on the essentials.
Pricing
Clastify
When it comes to pricing, Clastify is a more affordable option because Clastify believes money should never be an obstacle to education. You can get Clastify Premium for $7.99 or Pro for $13.99 per month. For tailored IB Examiner feedback that guides exactly how to score top marks, students can submit their coursework for review at an affordable price of around $49 (the exact price depends on whether it's an IA, EE, or TOK).
Revision Dojo
Revision Dojo on the other hand will cost you $21 (''Pro'') or $29 (''Premium'') for a month.
Verdict
Clastify offers strong value for students by combining high-quality support with a more accessible price, making it a more practical choice for those looking to get the most out of their investment.
Conclusion
Clastify is a strong option for IB students seeking reliable, high-quality support. While Revision Dojo uses a more general ChatGPT-based system, Clastify uses its own AI tool, Clai, which is trained specifically on IB exemplars and markschemes. This approach helps ensure that feedback is precise, actionable, and closely aligned with IB assessment standards. We offer AI to support students during coursework drafting, while final submissions are always reviewed by human examiners, which, along with a double-check, always guarantees reliability. Clastify also offers a clear, easy-to-navigate interface with well-organized exemplars. Pricing is designed to remain accessible, with affordable premium subscriptions and coursework reviews.
