Ace your IB Components
Includes student-tailored generated exemplars, criterion-referenced evaluations, and verified checklists across all assessment components—including Internal Assessments, Extended Essays, Theory of Knowledge, and Individual Orals—developed directly from official markschemes.
Everything you need, in one place
Four tools that work off the same foundation of real IB criteria and examiner guidance.
Structured guides for every IA, EE, TOK, and IO — the official criteria and examiner guidance, organized the way you actually write.
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.
See it in action
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. Integrated navigation tools allow direct access to specific draft sections without manual scrolling. Your free library of IB Coursework knowledge.
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 ensure you are in the highest band for your subject. The assessment module automatically calculates an estimated score based on completed milestones, providing transparent progress tracking throughout your IB journey. Your completely free IB companion.
Why ScholarLib
Every model, score, and checklist step is calibrated against real IB assessment criteria and genuine examiner justifications — not generic AI guesswork.
Each of the 12 supported subjects and assessment types runs its own dedicated scoring model tuned to that subject's real criteria — Business Management's seven-criterion A–G scheme, 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 show you exactly why a passage earns its mark, not just what mark it got.
