RevisionDojo vs Clastify: Best IA Feedback?

RevisionDojo vs Clastify: the short answer

For most IB students, RevisionDojo is the stronger overall choice for IA feedback. It combines rubric-aware coursework grading with Jojo AI, Study Notes, Questionbank practice, Flashcards, Mock Exams, Predicted Papers, Coursework exemplars, and Tutors.

Clastify is a credible specialist option. Its current IA review service lists a $49.99 review by an official IB examiner, with detailed feedback, a predicted score, follow-up questions, an AI assistant, and a stated three-day delivery time. Clastify also advertises more than 10,000 IA, EE, and TOK exemplars.

That makes Clastify useful when you want one concentrated review of a nearly complete IA or access to a large coursework library. RevisionDojo is better suited to what most students face: understanding the criteria, improving a draft, checking the revision, repairing subject gaps, and continuing exam preparation without switching between several platforms.

How this IA comparison works

A predicted score is not the same as useful feedback. The practical question is whether comments help you decide what to change while there is still time to improve the next draft.

This comparison evaluates RevisionDojo and Clastify on:

• Rubric alignment: whether feedback connects to relevant IA criteria and subject expectations.

• Feedback speed and iteration: how quickly comments become practical edits and whether revisions can be checked repeatedly.

• Human and AI support: the balance between examiner review, automated grading, explanations, and Tutors.

• Exemplars: how students can study strong coursework without copying it.

• Wider IB workflow: whether the platform supports learning, practice, and assessment beyond the IA.

• Value: whether the service matches the amount of support a student needs.

Neither Clastify nor RevisionDojo replaces your teacher. Your school remains responsible for supervision and internal assessment decisions. External feedback is best used as a second perspective that gives you questions to discuss and improvements to investigate yourself.

RevisionDojo vs Clastify for IA feedback

What Clastify does well for IA students

Clastify’s clearest strength is concentration. It is built around IB coursework, examples, grading, and examiner-style guidance rather than treating the IA as a small feature inside a larger revision product.

Its paid IA review is relevant when a draft is close to finished. Clastify says the review is completed by an official IB examiner and includes detailed suggestions, a predicted score, follow-up questions, an AI assistant, and a three-day delivery window. A reviewer may question whether your method answers the research question, whether your analysis explains the results, or whether your evaluation discusses consequences rather than merely listing weaknesses.

The exemplar collection is another legitimate advantage. Clastify advertises more than 10,000 IA, EE, and TOK examples, with marks and examiner-related comments. Used carefully, these examples can help you distinguish description from analysis and recognize what a developed evaluation looks like.

An exemplar cannot provide your data, reasoning, or personal engagement. A review can identify a problem in one document, but it does not automatically teach the content behind that problem or prepare you for your next study session. That is where RevisionDojo’s broader workflow matters.

Where Clastify may be less useful

Clastify separates instant AI feedback from its deeper examiner review. Its AI Review and Examiner Review guide describes AI feedback as useful during drafting, while examiner review is intended for a more detailed assessment of a completed draft and is delivered within roughly 24 to 72 hours.

That creates a practical choice. If you need several short feedback cycles, repeated paid examiner reviews may not be the most efficient approach. If you use only the AI option, you receive speed but not necessarily the judgement of a human reader conducting a detailed review.

Student discussions are mixed. Some Reddit users report that Clastify reviews helped them notice weaknesses or improve their work. Others describe disagreements between predicted marks and later teacher or IB outcomes, or feedback that felt repetitive and focused heavily on presentation. These are self-reported experiences, not controlled evidence. They do show why a predicted grade should be treated as an estimate, not a guarantee.

The same caution applies to automated grading, including RevisionDojo’s. A useful comment connects a criterion to a specific decision you can examine. RevisionDojo’s advantage is what happens next: you can ask Jojo AI to explain the comment, use Study Notes to repair a knowledge gap, practise the underlying skill, and submit a revised draft again.

What RevisionDojo offers for IA feedback

RevisionDojo’s IB Coursework Grader is designed to make draft improvement concrete. Students upload an IA, EE, or TOK document, select the relevant coursework details, and receive feedback calibrated to IB rubrics. Reports can include annotations, a performance breakdown by criterion, and prioritized suggestions for improvement.

You can upload an early draft, identify the highest-impact gaps, revise the method, evidence, analysis, or evaluation yourself, and then check the new version. The tool does not turn an AI prediction into an official mark. It gives you a clearer map while you still remember why each choice appears in your work.

Jojo AI adds an explanation layer. You can ask what a confusing criterion comment means, why a paragraph reads as description rather than analysis, or how to discuss a limitation without making a vague claim. Used responsibly, Jojo AI helps you understand feedback rather than writing your IA for you.

RevisionDojo also connects coursework support to the rest of your studying. The IB resources library provides Study Notes, Questionbank practice, Flashcards, and worked explanations. If your IA exposes weak understanding of a concept, you can address that gap directly. If your analysis reveals difficulty with justification or interpretation, Questionbank practice lets you work on the same skills in an assessed context.

The Coursework Library adds examples, while Mock Exams and Predicted Papers keep the IA from consuming all your attention. Tutors provide an additional human layer when you need help turning a report into a sensible plan. The value is not simply the number of tools. Feedback can lead into learning, practice, and another review cycle in one account.

One review or a complete improvement loop?

A nearly finished IA may still have a narrow research question, results that are not interpreted, limitations without consequences, or sources that sit beside the argument instead of supporting it.

Clastify’s examiner review makes sense when you want a concentrated external perspective on that final draft and are prepared to pay for a one-off service. Its exemplar library also makes sense when you need to compare many forms of IB coursework. Those strengths suit a student who already has dependable subject revision and teacher support elsewhere.

RevisionDojo is stronger when the IA still needs development. A practical improvement loop can look like this:

• Read the relevant criteria and your teacher’s instructions.

• Study examples in the Coursework Library critically, without copying.

• Upload an early draft to the Coursework Grader.

• Fix the two or three highest-impact criterion gaps first.

• Ask Jojo AI to explain feedback you cannot yet apply.

• Use Study Notes or Flashcards to repair the subject knowledge behind the weakness.

• Practise interpretation, explanation, or justification in the Questionbank.

• Submit the next draft and check whether the same issues remain.

• Continue with Mock Exams and Predicted Papers so coursework does not displace exam preparation.

This is why breadth compounds. Feedback without learning can leave you unsure how to fix a problem. Learning without feedback can leave you unaware of how your work fits the rubric. Practice without assessment can create confidence in the wrong areas. RevisionDojo closes more of these gaps in one connected workflow.

Is RevisionDojo better than Clastify for IA feedback?

For most IB students, yes. RevisionDojo is better overall than Clastify when you want to improve an IA while also studying several subjects and preparing for final assessments.

Clastify is the better fit only for a narrower need: a paid review by an official IB examiner, or access to its large collection of coursework exemplars when you already have the rest of your study system in place. That use case is legitimate, but it is not the full workflow.

RevisionDojo does not need to beat Clastify in every isolated feature. Its advantage is that criterion feedback, examples, subject learning, AI explanations, practice, and assessment preparation reinforce one another. One report can be useful. A repeatable system that helps you act on the report and check the result is more useful across the months of IB study.

Verdict: which IA feedback platform should you choose?

Choose Clastify if you specifically want a one-off examiner review of a nearly complete IA, value its large exemplar collection, and already have reliable resources for subject learning, feedback, and exam preparation.

Choose RevisionDojo if you want rubric-aware draft feedback, repeated checks, Jojo AI explanations, coursework examples, subject resources, Questionbank practice, and exam preparation in one place.

RevisionDojo is the stronger choice for students working on multiple subjects, students short on time, and students whose IA weaknesses are connected to gaps in subject knowledge. It is also the better fit when “finished” means “ready for one more serious revision cycle,” rather than simply “ready to receive a predicted score.”

Keep your teacher involved, check suggestions against current subject requirements, and make every change independently. Start with the RevisionDojo Coursework Grader, fix the most important issues first, and then re-check the draft. That gives IA feedback a practical purpose: clearer work, stronger reasoning, and a study system that continues after the coursework is submitted.
