RevisionDojo vs Clastify: the short answer
RevisionDojo is usually stronger for students who need one platform for full IB revision, exam practice, and coursework support. Clastify may be better for students focused on detailed IA, EE, or TOK exemplars and a paid review by a human IB examiner. The platforms overlap, but they begin with different priorities.
Clastify has a coursework-first identity. Its resources include IA, EE, and TOK exemplars, examiner-created comments and mark schemes, an AI Grader, research-question tools, question practice, revision materials, and tutoring. RevisionDojo combines coursework tools with Study Notes, Flashcards, a large Questionbank, Mock Exams, Predicted Papers, Jojo AI, and human Tutor support.
The right choice depends on your workflow. A student finishing an EE may need criterion-specific feedback, while that same student still needs a sustainable way to revise six subjects and prepare for timed papers.
What each platform is designed to do

| Best overall fit | Students managing coursework and examination revision together | Students prioritising coursework research, exemplars, and specialist review |
Features can change, so check current product pages before purchasing a plan or review. Neither service is endorsed by the International Baccalaureate, and neither determines an official final mark.
IA, EE, and TOK exemplars
Exemplars make abstract assessment criteria easier to understand. A strong example can demonstrate suitable research-question specificity, the difference between description and analysis, and how evidence supports a conclusion.
Clastify’s central strength is its visible coursework library. Clastify states that it offers thousands of IA, EE, and TOK examples, with grades and reviews checked through its verification processes. It also attributes coursework comments and mark schemes to experienced IB examiners. This is useful when a student wants to compare several examples from the same subject or component before drafting.
RevisionDojo also provides exemplars, guides, and criterion-focused tools. Its advantage is that examples sit beside the subject knowledge and practice needed to improve the work. A Biology IA student could review Study Notes, practise data interpretation in the Questionbank, ask Jojo AI to clarify a method, and use the Coursework Grader to identify draft weaknesses.
An exemplar is one possible approach, not a template. The IB assesses the student’s own research, reasoning, communication, and reflection. Closely imitating an exemplar’s wording, argument, data, or structure can create academic-integrity concerns.
Human examiner review versus AI feedback
Human examiner review and AI-generated feedback are not equivalent. A human reviewer can interpret ambiguity, recognise subject-specific problems, and explain why work does or does not satisfy a criterion. AI feedback is faster and reusable during drafting, but it remains a provisional learning aid.
Clastify separates AI Review from its Examiner Review service. Its published information says the AI Grader gives an instant predicted grade and criterion-based suggestions, while Examiner Review is completed by human IB examiners. Clastify says AI may help clarify examiner comments, but substantive assessment and marking are attributed to human examiners. Before purchasing, confirm the service scope, turnaround time, reviewer qualifications, and deliverables.
RevisionDojo’s Coursework Grader and Jojo AI provide formative support. They can help interpret criteria, identify missing analysis, improve organisation, and suggest a next step. RevisionDojo states that this feedback is not official IB grading and that teachers retain final judgment. Tutors add human guidance but do not replace the school supervisor responsible for authenticating the student’s process.
Use AI during planning and revision, then ask a teacher or supervisor to resolve important questions. Human guidance is especially valuable for subject-guide interpretation, ethics, data quality, authenticity, or whether a proposed change is permitted.
Question practice and exam preparation
This is the clearest difference in the RevisionDojo vs Clastify comparison. RevisionDojo connects learning, recall, application, and exam simulation. Its Questionbank supports targeted practice by subject and topic, while Test Builder and Exam Mode support customised or timed assessments. Study Notes, lessons, videos, Cheatsheets, and Flashcards reinforce the knowledge that question practice requires.
Jojo AI can explain concepts, generate targeted practice, and comment on answers. Flashcards work well for definitions, formulas, vocabulary, processes, and examples, but should not replace extended responses. Mock Exams and Predicted Papers develop timing, stamina, and command-term skills. Predicted papers are preparation materials, not reliable forecasts of exact exam questions.
Clastify also provides question banks, revision notes, flashcards, and AI-assisted feedback, making it more than an exemplar library. However, coursework remains its strongest point of differentiation, whereas RevisionDojo is structured more clearly around an integrated daily revision system.
Whichever platform you choose, consistent practice matters more than collecting resources. One useful loop is to read a short notes section, complete targeted questions, analyse errors, turn recurring mistakes into Flashcards, and attempt a timed section later that week.
Research questions, tutoring, and guidance
A weak research question can undermine an IA or EE. It may be too broad, depend on unavailable evidence, invite description rather than analysis, or conflict with subject requirements. Research-question tools can test feasibility, but they cannot approve a project.
Clastify offers a Research Question Generator and Research Question Evaluator for initial ideas and comments about scope or alignment. Students must still determine whether a question is sufficiently original for their school context, ethically appropriate, feasible with available evidence, and acceptable to their teacher or EE supervisor.
RevisionDojo uses Jojo AI, coursework guidance, exemplars, and Tutors for the same planning stage. Its broader study system also lets students test whether they understand the knowledge, calculation, or method required before committing to an investigation.
On either platform, guidance is not authorship. A tutor may explain a criterion, ask questions, or identify an unclear argument, but the student must make the decisions and write the assessed work. Avoid services promising grades or offering to rewrite coursework.
Academic integrity checklist
The IB requires submitted work to be the student’s authentic work and expects sources and permitted assistance to be acknowledged. Its artificial-intelligence guidance also explains that AI-produced material does not become the student’s own work merely because it was edited or paraphrased.
Use either platform responsibly:
- Study exemplars to understand criteria, structure, evidence, and standards, never to copy language, arguments, data, or references.
- Keep a research log showing how your question, method, sources, and conclusions developed.
- Follow school rules for AI, editing, tutoring, and draft feedback.
- Ask how AI assistance must be acknowledged for your subject and assessment component.
- Never submit generated paragraphs, fabricated citations, invented data, or another student’s ideas as your own.
- Preserve drafts and notes so you can explain your thinking during authentication procedures.
These practices protect academic integrity and demonstrate that the investigation and reasoning belong to you.
Which platform should you choose?
Choose Clastify if your immediate problem is an IA, EE, or TOK task and you want to compare multiple coursework examples or purchase a dedicated human Examiner Review. It also fits students who value research-question evaluation more than a comprehensive daily examination routine.
Choose RevisionDojo if you want one connected workflow across the Diploma Programme. Study Notes, Questionbank, Flashcards, Jojo AI, Mock Exams, Predicted Papers, coursework exemplars, and AI-supported grading reduce the need to switch among separate tools. Tutors and coursework guidance provide additional help when automated feedback is insufficient.
Using both can be reasonable: Clastify for specialist human review near the end of a coursework project, and RevisionDojo for learning, spaced recall, question practice, and timed exams. If budget or attention is limited, start with the platform addressing your most urgent bottleneck and verify important advice with your teacher or supervisor.
Conclusion
RevisionDojo vs Clastify is ultimately a comparison of priorities. Clastify is strongest when coursework exemplars, research-question tools, and human examiner review drive the decision. RevisionDojo is strongest when IA, EE, and TOK support must coexist with notes, flashcards, question practice, AI assistance, and realistic exam preparation.
Neither replaces the IB subject guide, your teacher, your EE supervisor, or your judgment. Use exemplars for analysis rather than imitation and AI for formative support rather than authorship. For most students balancing coursework with exams, RevisionDojo offers the more integrated starting point; Clastify remains compelling for specialist coursework comparison and review.
