AI tutor for the Mauritanian Baccalaureate

Prepare for the BAC with absolute precision.

BacMR answers from the official Mauritanian textbooks, in Arabic and French, and cites the page. Type your question, say it, or send a photo of the exercise.

Example

You: How do I differentiate f(x) = sin(3x²)?

BacMR:

Use the chain rule: the outer function is sin(u), the inner one is u = 3x².

f′(x) = cos(3x²) · 6x = 6x cos(3x²).

In the exam, name the rule and write the inner derivative on its own line.

How it works

Three steps, every time. No guessing, no generic internet answers.

  1. 1

    Ask in Arabic or French

    Type it the way you would ask a teacher, record a voice note, or attach a photo or PDF of the exercise. You check the text before it is sent.

  2. 2

    BacMR finds the passage

    It searches the official textbooks for your series and level and pulls the passages that answer you.

  3. 3

    You get the answer, cited

    A step-by-step explanation with the textbook and page number. When the book has a diagram or curve for it, the figure appears in the answer.

What you can do in the chat

Available today in the web app, on a phone or a computer.

  • See the figure

    When the textbook has a diagram, curve or table for your question, BacMR shows it inside the answer.

  • Ask by voice

    Record your question in Arabic or French. It becomes text you can correct before sending.

  • Send a photo or a PDF

    Photograph an exercise or attach a PDF page. BacMR copies its text into your message.

  • Choose a tutor style

    Simple explanations, a BAC examiner who answers like a model correction, or a revision coach.

  • Browse your programme

    Open the chapters of your textbooks and ask about one chapter in particular.

Questions, answered

What is BacMR?

An AI tutor that answers from the official Mauritanian baccalaureate textbooks, in Arabic and French, and cites the page it used.

Which textbooks does it use?

The 7AS (BAC year) textbooks for series C, D, LM and LO, plus some 6AS books. Not every subject is covered for every series yet; more books are being added.

Does it work on a basic phone?

Yes. The site is built to load fast on 3G and on low-cost Android phones, and a conversation uses less data than a short video.

Can I ask with my voice or a photo?

Yes. Tap the microphone to dictate, or the paperclip to send a photo or PDF of an exercise. The text appears in your message so you can fix it before sending.

What does it cost?

New accounts get 500 welcome credits, about 60 typed questions, plus a free daily allowance. A typed question uses about 8 credits. Paid plans with a larger daily allowance are listed in the pricing section; a plan without a price is coming soon.

How do I sign in?

In the app: open the web app (chat.bacmr.ai) or the mobile version (ui.bacmr.ai), then sign in with your email address or your Google account.

Is there a mobile app?

Is it only for students?

It is built for students. Teachers and parents can use the same tutor to check a lesson; dedicated teacher and parent tools are not available yet.
