Built From Real Top-Scoring IB Student Work
ScholarLib provides student-tailored generated exemplars, criterion-referenced evaluations, and verified checklists for Internal Assessments, Extended Essays, Theory of Knowledge, and Individual Orals, all modeled on real, top-achieving student exemplars and examiner insights, calibrated against the IB's official assessment criteria.
What You Get
Four tools that work off the same foundation of real IB criteria and examiner guidance.
Follow structured guides for every IA, EE, TOK, and IO, covering the official criteria and examiner guidance, organized the way you actually write.
Generate a criterion-referenced, top-mark-band model response for your subject, built around your own research question and topic.
Submit your own draft and get a holistic score, a per-criterion breakdown, and annotated commentary anchored to your text.
Tick off real, examiner-grounded writing steps as you draft, with an Examiner Panel that estimates your marks live.

Real screens from the app. These switch with your theme.
Guides are structured around key assessment types, including Internal Assessments, Extended Essays, Theory of Knowledge, and Individual Orals, with integrated navigation tools for direct access to specific draft sections without manual scrolling. The full library is free to use.
Generate high-scoring exemplars tailored to specific subjects and research questions. Select highlighted passages to review examiner commentary explaining why the text satisfies criteria and how inferior responses fail to meet those standards.
Submit your IA/TOK/EE draft to receive comprehensive evaluation just like the drafter: an overall mark, detailed criterion breakdown, and inline annotations detailing the specific revisions required to reach higher mark bands.
As you write your IA/TOK/EE, use our handcrafted markscheme checklist to stay in the highest band for your subject. The assessment module calculates an estimated score automatically as you complete milestones, so you can track your progress as you go.
Why ScholarLib
Every model, score, and checklist step is calibrated against the IB's official assessment criteria, real exemplars from top-scoring IB students, and examiner insights.
Each of the 12 supported subjects and assessment types runs its own dedicated scoring model tuned to that subject's real criteria, for example Business Management's seven-criterion A–G scheme, or Global Politics' SL/HL scope difference.
The Extended Essay and several Internal Assessment subjects already reflect the new first-assessment-2027 syllabus. Wherever official IB grade boundaries haven't been published yet, every score is clearly flagged as a provisional estimate, never presented as final.
Upload a PDF or paste text directly. Tables in your submission are preserved and re-rendered instead of flattened into prose, and mathematical notation converts to real Unicode sub/superscripts instead of leaving stray underscores and carets behind.
Twelve subjects across the sciences, individuals & societies, mathematics, and language & literature, plus TOK Exhibition, TOK Essay, and the English A Individual Oral.
Annotated commentary and a live Examiner Panel explain exactly why a passage earns its mark.
