Why now

AI didn't wait for the education system

Your students already write, translate, and study with AI every day. Assessment hasn't caught up: the same old exams, whole weekends spent grading, and a final grade that says nothing about what each student didn't understand.

Mentora closes that gap. Advanced AI models draft the questions and grade the answers, then turn every exam into a clear picture of what each student hasn't understood yet. Learning moves faster, and every decision that matters is still yours.

Insight, not just a score

Topic-by-topic results show where the class struggled, so your next lesson targets the gap instead of repeating the whole unit.

Hours back every week

Mentora grades in minutes what used to take you hours. That time goes back to what matters: planning lessons and helping your students.

You stay the teacher

Mentora drafts; you edit, replace, and approve. Nothing reaches a student until you've reviewed it.

How Mentora accelerates learning

One loop, every week: assess, understand, act.

How AI grading works

Graded the way you'd grade it

You set the criteria for each question. Mentora grades every answer against them, point by point.

  1. 1

    You set the criteria

    For each question, you write what a correct answer must mention and how many points each criterion is worth.

  2. 2

    Mentora grades point by point

    It checks every answer against your criteria and awards the points. The same answer always gets the same grade.

  3. 3

    If Mentora is unsure, it asks you

    The grade waits until you've reviewed it. The student won't see it before you do.

  4. 4

    You have the final say

    See why each point was awarded and change it if you disagree. Students only see the grades you confirm.

How AI grading works, and how accurate it is

Grounded in global standards

Designed around public frameworks for digital education

UNICEF's Digital Education Strategy 2025–2030 calls for technology that is human-centered, equitable, and evidence-based, with teachers at the center rather than on the sidelines. That's the blueprint we built Mentora on.

Human-centered, with teachers at the center

The strategy's central shift is from technology-led tools to teachers who shape the technology. In Mentora, AI drafts and the teacher approves: nothing reaches a student without review.

Outcomes over outputs

UNICEF asks edtech to measure learning, not just participation. Mentora's reports answer exactly that question: what did each student actually understand?

Evidence-based decisions

The strategy names weak tracking of learning outcomes as a core barrier. After every exam, Mentora shows what each student understood, question by question and criterion by criterion, so decisions rest on evidence, not hunches.

Teaching time protected

UNICEF ranks administrative overload among the biggest threats to education quality. Automatic grading and reports give those hours back to teaching.

Read the frameworks

These public frameworks guide how we design Mentora. Mentora is an independent product, not affiliated with or endorsed by UNICEF or UNESCO.

Everything a modern classroom needs

Built for teachers first: AI handles the busywork, you make the calls.

Live exams

Watch in real time who's opened the exam, how far each student has gotten, and who's already turned it in.

A debrief after every exam

What the class understood, which wrong answers they picked, who needs help, and what to do in the next class.

Virtual classrooms

Invite students by email or join code, and manage classes and rosters without a spreadsheet.

Windows and time limits

Open and close exams on a schedule, set time limits, shuffle questions, and accept late submissions.

Frequently asked questions

What is Mentora?
Mentora is an AI exam generator and grader for teachers. It drafts exams from a short description, grades every answer against your rubric, written answers included, and turns the results into a debrief: the misconceptions behind wrong answers, who needs help, and what to teach next.
How does the AI exam generator work?
Describe the exam you want (subject, topics, difficulty, and number of questions) and Mentora drafts it in seconds. Every question is editable: rewrite it, swap it for a new AI suggestion, or add your own. Nothing is published until you approve it.
Can an AI grader grade essays and written answers?
Yes, from short answers to essays. You set the criteria for each question, and Mentora grades every answer against them, point by point. If Mentora isn't sure, you see the answer before the student does, and you can open any grade, see why it was given, and change it.
How do students join a classroom?
Students join with an email invitation or a six-character join code. Teachers decide whether the join code is active and can remove students at any time.
Do I need AI experience to use Mentora?
No. If you can describe the exam you want in plain language, Mentora does the rest. There are no prompts to write and no settings to tune.
What happens after students finish an exam?
Mentora grades every submission and writes a debrief: the score distribution, how each question went, which wrong answers students picked, the most common misconceptions, who needs individual support, and what to do in the next class.
How does Mentora help students learn faster?
By shortening the time between teaching and feedback. Exams are graded as students turn them in, and each debrief tells you which misconceptions to address and who needs help, so weak spots get retaught within days instead of at the end of the semester.
Can Mentora identify learning gaps?
Yes. After every exam, Mentora separates teaching gaps (most of the class missed it, so reteach it) from learning gaps (a few students missed it, so support them), and backs each one with evidence from student answers.
