At Clastify, we take great pride in the quality and accuracy of all our notes, questions, flashcards, and other study materials. Every resource is created and moderated by experienced IB examiners and subject specialists to ensure it is accurate, relevant, and aligned with IB standards. To make our study content even clearer and more helpful, we occasionally use AI to enhance explanations, improve wording, and generate helpful diagrams. AI is used only as a supporting tool and never replaces human expertise or oversight. In this post, we'll explain how our study materials are created, where and how AI is used, and provide examples of content before and after AI enhancement.
How Clastify Uses AI to Improve Study Content
What’s Done by Real People (and How AI Helps)
When a note, flashcard set, question bank, or other learning resource is published on Clastify, here's what actually happens:
- A certified IB examiner carefully creates the content based on the syllabus and their subject expertise.
- This content is then run through our internal AI tool that:
- Flags any mistakes or confusing parts and suggests fixes
- Improves the tone and style to make it more understandable
- Fixes typos
- Helps generate useful images and graphs
- All AI-generated suggestions are presented to the examiner for review. The examiner must manually approve, modify, or reject each suggestion - nothing is added to the content without human oversight.
Before any resource is published, it undergoes a final quality assurance review by a second examiner. This additional check helps ensure that the content is accurate, clear, and fully aligned with the IB syllabus.
It's important to emphasize that all subject knowledge and educational decisions are made by experienced IB educators. AI is only used to improve presentation, clarity, and consistency - never to determine what students should learn.
Real Examples
To help you understand how Clastify’s content creation process works in practice, here are a few real examples of how our human examiners and AI collaborate - always with the human in full control.
Example 1:
An examiner is creating study notes for Biology Unit A1.1: Water.
Original content written by the examiner:
Water molecules are polar because oxygen attracts the shared electrons more strongly than hydrogen. This causes hydrogen bonds to form between water molecules.
AI improvement:
Water molecules are polar because oxygen attracts the shared electrons more strongly than hydrogen, creating a partial negative charge (δ⁻) on the oxygen atom and partial positive charges (δ⁺) on the hydrogen atoms. These unequal charges allow neighbouring water molecules to attract each other through hydrogen bonds, which are responsible for many of water's important biological properties, including cohesion, surface tension, and its high specific heat capacity.
The examiner reviewed the suggested revision, confirmed that it was scientifically accurate and aligned with the IB syllabus, and approved it.
Example 2:
An examiner is creating IB exam-style questions for Physics Unit D.4: Induction.
MCQ question created by the examiner: What is the SI unit of magnetic flux?
The AI was asked to generate 4 possible answers, with only one being correct:
a. volt metre
b. weber
c. second
d. tesla
The examiner read the AI-suggested answers and decided that option c is too simple and not representative of the IB exam. Therefore, the examiner decided to make manual edits, which resulted in the final version:
a. volt metre
b. weber
c. newton per ampere
d. tesla
How AI Has Improved Content Quality
At Clastify, we publish thousands of study resources across IB subjects. One of the biggest challenges of maintaining such a large library is ensuring that content remains consistently clear, accessible, and up to date.
Our examiners are experts in their subjects, but like all educators, they naturally have different writing styles. While the academic quality of our content has always been our highest priority, AI helps us present that expertise in a more consistent and student-friendly way.
With AI assisting our editorial process, we've seen significant improvements in:
- Clarity: Complex ideas can be explained more clearly and in language that is easier for students to understand.
- Consistency: Terminology, formatting, and writing style are more standardized across different resources and subjects.
- Accuracy: AI helps identify potential mistakes, inconsistencies, or areas that may require additional review before publication.
- Efficiency: Examiners spend less time on formatting and editing, allowing them to focus more on the academic quality and syllabus alignment of the content itself.
Most importantly, these improvements are achieved without compromising quality because every AI-generated suggestion is reviewed by qualified human examiners before publication.
