The difference
Not another generic AI chatbot.
Wenzify's value comes from combining your assessment criteria, your submission and structured, evidence-based evaluation — not open-ended chat about your essay.
Criterion-by-criterion evaluation
Every criterion is assessed on its own terms — with an estimated score, status and confidence — instead of one vague overall impression.
Course-specific workflow
Feedback is shaped by your subject and assessment type, following the structure your examiner actually uses.
Evidence-based feedback
Each point references your own writing. No invented quotes, no fabricated content — only what appears in your work.
Revision comparison
Upload a new draft and see exactly which criteria improved, which held steady, and what still needs attention.
Academic progress tracking
Your analyses build a history, so you can see how your work develops over time — not just a single snapshot.
The question we answer
What exactly should I improve before I submit?
Not what does an AI think of my essay?

From draft to confident submission.
A focused, three-step workflow designed around the way IB coursework is actually assessed.

Features
Everything you need to improve — nothing you don't.
Built for every IB Internal Assessment — and for academic integrity: Wenzify guides you, it never writes your coursework.
Every IB subject, one tool
Economics, the sciences, maths, history, psychology, business, global politics and more — each marked against its own official assessment criteria.
Estimates that don't jump around
Every submission is graded several times against its criteria and the median kept, with exactly what would lift each one to the next band.
Comments on your actual text
Like a teacher's margin notes: click a highlighted sentence to see what's working and what to fix.
Figure-by-figure feedback
Diagrams, graphs, tables and equations checked wherever your subject needs them, with precise, specific fixes.
Every draft tracked
Scores, length and checklist progress draft by draft — a clear record that the work is your own.
Economics portfolio planner
For the Economics portfolio: all three commentaries together — units, sources and key concepts, clashes flagged, and a predicted grade.
Article & Diagram checks for Economics
Planning an Economics commentary? Check an article's fit before you write, and verify a diagram before it goes in.
English, Español, Français
Write in any of the IB's working languages and get your feedback back in the same one.
For students
Feedback that helps you learn — honestly.
Wenzify is designed to make you a stronger writer and analyst. It explains, questions and guides, so the improvement is genuinely yours.
- Understand exactly how your work maps to each criterion
- See your strengths, not just your weaknesses
- Get concrete, actionable next steps — not vague advice
- Improve your own reasoning instead of outsourcing it
- Track your progress from first draft to final submission
Wenzify helps you improve your own work. It is designed for feedback, explanation and reflection — not to produce assessed coursework on your behalf.
