AI Tools That Work With You, Not For You
Two tools, each built for one job. The AI tutor sits down with a question you got wrong and gets you to find the mistake yourself. The AI grader reads an IB internal assessment or extended essay against the published criteria and tells you where it stands.
- AI tutor: first minutes free
- Grader: per piece of work
- Prepaid, no subscription
- Alongside tutoring or on their own
The AI tutor
It starts from one mistake in a TestPrep practice test.
It asks before it tells
It works up a ladder: from a nudge to look again, through a hint and a single worked step, to a full solution only when the guided attempts are spent.
You work out loud
By voice, on a shared board it can read, with the exam’s calculator open where the test has one.
It names the mistake
Sign slip, misread question, missing concept — recorded per question, so the repeating pattern becomes visible.
It never withholds the answer
Ask for the answer and you get it. There is also a button for it on screen at all times.
The IA and EE grader
Against the published criteria
Each check reads the work against the IB’s assessment criteria for that component and explains where marks are likely being lost.
Feedback, not rewriting
It comments; it does not write or redraft. The work stays the student’s own, as the IB requires.
Before a supervisor’s read
Used before a draft goes to a teacher or tutor, it makes their time go further.
AI tool prices
Both tools are prepaid. Nothing is a subscription and nothing renews on its own.

IB Extended Essay Grader
Get AI feedback on your Extended Essay against the IB criteria for your exam session: the new criteria (30 marks) from May 2027, and the 2018 criteria (34 marks) up to November 2026. You get detailed feedback on every criterion and an estimated A–E grade.
Your exam session
The IB marks the Extended Essay against new criteria from the May 2027 session. If you sit your exams in November 2026 or earlier, your essay is marked against the 2018 criteria.
Type of review
How is the A–E grade estimated?
The IB sets the Extended Essay’s grade boundaries again every session; there is no fixed table. So the estimate follows the grade descriptors the IB asks schools to use for predicted grades. The IB publishes your final grade at the end of the session.

IB Sciences IA Grader
Get AI feedback on your scientific investigation against the IB criteria in use since May 2025: Research design, Data analysis, Conclusion, Evaluation. 24 marks in total, and the criteria are the same at SL and HL.
Which IA is this for?
This tool is built only for the scientific investigation IA in IB Biology, Chemistry and Physics. The report is at most 3,000 words and counts for 20% of the subject grade. Maths, language and humanities IAs are marked against different criteria, so this tool does not review them.
