An answer of 0.75 can be correct and still tell you very little about whether an AI tutor helped you learn.
Can you explain where it came from? Could you solve a related problem without reopening the chat? Does the explanation match the question you were actually asked?
Those are more useful questions than which app describes itself as the best AI for IB students.
This guide compares tools for explanations, question practice, coursework support and note making, using product documentation checked on 28 September 2026.
This comparison is based on published features, not live trials. The shared IB question is a repeatable check you can run yourself, not evidence that one platform outperformed another.
One Real IB Question to Use Across Every Tool
Use Question 1 from the IB’s official Mathematics AA HL Paper 1 specimen paper, published for first examinations in 2021. In compact notation, the question is:
Given P(A)=0.5, P(B)=0.4 and P(A∪B)=0.6, find P(A|B).
Keep this question identical when comparing ChatGPT, Professor Curious, Newton, Jojo, Google’s notebook tool and Koncepts. Record the date, plan and mode used so you know what you are comparing. Start with the same instruction:
Help me solve this without a calculator. Give one hint at a time and wait for my response. Do not reveal the final answer first.
The reference solution, not an output from any compared tool, is:
P(A ∩ B) = 0.5 + 0.4 − 0.6 = 0.3.
P(A | B) = P(A ∩ B) / P(B) = 0.3 / 0.4 = 0.75.
The official markscheme supports this method and also accepts a valid Venn diagram approach.
Look beyond the final number. Does the tutor help distinguish the union from the intersection? Can it explain why the denominator is P(B)? Does it leave you something to work out?
For a second round, provide every tool with the same official solution and ask it to connect each step to your working. Record which materials each tool can actually accept. An unsupported upload is a feature limitation, not an incorrect mathematical answer.
One question cannot establish performance across the IB, or test note making and coursework support adequately. Use it as an initial check, not a verdict. MYP students can apply the same approach to a task supplied by their teacher, using the accompanying criteria rather than assuming this DP example covers their assessment needs.
For Explanations: ChatGPT and Professor Curious
ChatGPT is worth considering when you need a concept explained differently. OpenAI’s study mode documentation describes guided questions, layered explanations, understanding checks and support for uploaded course materials.
That makes it misleading to claim a general chatbot has never encountered a markscheme. Students can provide relevant materials. The practical question is whether the response uses the correct source accurately.
On the shared probability question, ask ChatGPT to explain conditional probability before moving through the calculation. Keep your course, level and paper restrictions explicit.
The limitation is documented rather than hypothetical: OpenAI says study mode can make mistakes and may sometimes give a direct answer despite its intended approach. A fluent explanation still needs checking.
Professor Curious combines explanations with study activities. Its current product page advertises question scanning, guided explanations, flashcards, notes and quizzes, with IB subjects among its offerings.
That makes it a candidate for students who want to move between understanding a question and reviewing the underlying concept.
However, the published feature list does not establish how accurately it handles your exact IB course or an unfamiliar markscheme. For the shared question, look for a genuine explanation of “given B”, not merely a sequence of substitutions. Treat that as something to test, not a capability already demonstrated here.
For IB Question Practice: Newton and RevisionDojo
Revision Village’s Newton is closely connected to its practice resources. The provider’s help documentation says Newton recognises questions within its Questionbanks and Practice Exams, provides hints and is integrated into its markschemes. It also supports image uploads.
Its product page explicitly advertises:
“Feedback directly against the IB mark scheme”
That is a specific claim worth investigating, especially when you already use Revision Village questions. It is not independent evidence that every response is correct.
For the shared probability question, distinguish guidance on an uploaded external question from guidance inside Newton’s existing question context. Do not assume both have the same supporting material.
Access also matters. Revision Village’s public page ties Newton to Gold subject access and notes usage limits. Check the current conditions before buying a subject package mainly for its AI support.
RevisionDojo’s Jojo brings conversation into a broader revision platform. Its Jojo product page describes subject and level context, bringing notes or questions into the conversation, and working through checkpoints rather than jumping straight to an answer.
The RevisionDojo platform guide connects that support with notes, practice questions, flashcards and coursework feedback.
For the shared question, inspect whether Jojo helps you identify the missing intersection before applying conditional probability.
The distinction to preserve is between convenient integration and demonstrated accuracy. An integrated platform may suit your routine, but its own feature list does not prove that its explanation is better than another tool’s response.
For Note Making: Google’s Gemini Notebook
Google’s NotebookLM links now lead to documentation for Gemini Notebook. It accepts sources such as PDFs, websites and audio, provides answers with source citations, and can turn material into study guides and other formats.
Consider it when the difficulty is organising existing readings rather than finding another explanation from general knowledge.
Upload only material you have permission to use. Ask for a concise account of the relevant ideas with references you can open and inspect.
For the shared probability exercise, use the second round to examine whether its explanation accurately reflects the supplied solution.
Its limitation follows from that design: an answer grounded in your sources is not proof that those sources are complete, correct or appropriate for your syllabus. Google also warns that the tool can make mistakes.
Compare the generated notes with your unit outline. A neat summary is not evidence that every required concept has been covered.
For Coursework: Keep AI in a Supporting Role
Coursework requires a different decision from ordinary revision. Before uploading an Internal Assessment, Extended Essay or TOK draft, ask your teacher what assistance is permitted.
RevisionDojo’s platform guide describes AI support for coursework feedback. That identifies a use case, not permission from your school or evidence that the software can authenticate your work.
A useful approach is to ask for questions about unclear reasoning, missing evidence or unexplained choices. Then decide what to investigate and revise yourself. Do not treat suggested references or generated data as material you have verified.
The IB’s AI guidance requires AI generated material included in assessment to be credited in the text and referenced in the bibliography.
Its academic integrity policy also makes clear that AI generated work is not the student’s own. Acknowledgment does not turn outsourced authorship into independent work.
Keep a record of assistance used and follow your school’s instructions. An encouraging AI comment is not a substitute for discussing a substantive research decision with your supervisor.
Where Koncepts Fits, and Where We Are Weaker
Koncepts for DP students brings together syllabus organised lessons, practice questions with markschemes and guided help, while keeping HL and SL distinct.
That combination is relevant when you want to move from learning a topic to attempting questions within an IB study environment. On the shared probability problem, apply the same expectation as elsewhere: guidance should help you reason through the next step, not merely display the result.
Our clearest limitation is the scope of free access. The current free plan includes the first two subtopics in each subject and five AI messages per session, with sessions resetting every two hours. That will not cover every student’s revision needs.
Try the available material before committing to broader access. We are not claiming a measured accuracy advantage over the other tools in this guide.
For course context, our guide to IB Maths AA or AI, at HL or SL can help you identify the distinctions your study resources need to respect.
Choose the Tool for Your Next Study Task
Start with one difficulty from recent teacher feedback.
For a confusing concept, evaluate the quality of the explanation. For question practice, examine whether the guidance fits the task. For notes, inspect source coverage. For coursework, establish the permitted boundaries before using any tool.
Then close the chat and attempt something independently.
Before paying, confirm your subjects, syllabus version, usage limits, billing terms and applicable age requirements. Save the responses from your own trial so you can compare what happened, rather than what a landing page promised.
The most useful AI tutor for IB is not the one that sounds most certain. It is the one whose help you can verify and then use without needing it beside you.
