What changes when you check IB essays

  • Academic register reads predictable

    A research question, a methodology and a formal conclusion follow conventions every IB student is taught. Formal academic writing can read as more predictable than casual prose.

  • Credited AI text is allowed

    A passage that is properly credited as AI-generated may well be highlighted. That's expected; the question is whether every highlighted passage is credited.

  • Citations and appendices add noise

    Bibliographies, data tables and appendices aren't the student's prose. Remove them before scanning.

  • Lab language in science IAs

    Methods and results in a science internal assessment use standard phrasing that can read as formulaic. Weigh highlights in the analysis and evaluation more heavily.

How to check IB essays

  1. Step 1: Remove the bibliography and appendices

    Scan the body of the essay only, without the reference list, data tables or appendices.

  2. Step 2: Scan the full draft

    Paste the essay or upload a .docx to get a human score and sentence highlights for the whole piece.

  3. Step 3: Match highlights to credited AI use

    Check whether red or yellow passages correspond to AI-generated text the student has credited in the text and the bibliography.

  4. Step 4: Keep drafts and notes

    Students should save drafts and research notes; they are the clearest way to [show how the work was written](/guides/how-to-prove-you-did-not-use-ai).

  5. Step 5: Supervisors: share the report

    On paid plans, a PDF report or share link lets a supervisor and student go through the same highlights.

Rules that apply

  • The IB: credit AI-generated work in the text and the bibliography

    The IB's guidance on AI in learning, teaching and assessment says students should be taught that AI-generated work included in a piece of assessment must be credited in the body of the text and appropriately referenced in the bibliography. The IB Academic Integrity policy includes an appendix with guidance on using AI tools.

IB students write long, assessed pieces: the extended essay, internal assessments and the TOK essay. The IB encourages learning with AI tools but expects AI-generated work in an assessment to be credited. Winston AI shows which sentences read as machine-written, so students can check their own drafts and supervisors can see where to ask questions.

Using AI the way the IB expects

The IB's approach is transparency: AI tools can support learning, but AI-generated material in assessed work has to be credited where it appears and listed in the bibliography. Your school may set stricter rules for the extended essay or a particular subject, so check with your supervisor or coordinator.

For supervisors and coordinators

Check drafts early, while there is still time to talk about process. If a highlighted section has no credited AI use, ask the student to explain how they wrote it and to show their notes.
