AI Answer Coach · marked step by step

Solve 2x² − 7x + 3 = 0 by factorisation. (3 marks)

  1. Split the middle term: 2x² − 6x − x + 31/1
  2. Factorise: (x − 3)(2x − 1) = 01/1
  3. Roots: you wrote x = −3. Setting x − 3 = 0 gives x = 3.0/1
Your marks2 / 3

Learned: a sign slip when reading off the roots.

Next: a 5-question fix set, then a retest later.

AI coaches that mark and explain

Built from NCERT and CISCE textbooks and checked against the official board marking schemes.

Try a real board question

A real question from a past CBSE board paper, with its checked solution. Pick an answer and see how it feels. The Answer Coach does the same for your own handwritten or typed working.

Loading a question

Stop losing the same marks twice

An AI study partner with four jobs, done for every answer you write.

  1. Learns

    Every wrong answer is tagged, such as a sign slip or a mixed-up formula. The platform notices when the same slip comes back, and builds your practice around it.

  2. Tracks

    Chapter by chapter: marks over time, chapters mastered, retests due, and a readiness range once there is enough data. Never a guess dressed up as a prediction.

  3. Gives feedback

    Step-by-step marks against the board marking scheme, where you lost each mark, and a full-marks answer to compare with, within moments of writing.

  4. Saves marks

    A short set to fix each repeat slip, retests that bring mistakes back later, board papers weighted to your weak chapters, and a plan that moves unfinished chapters forward.

The AI features, in your pocket

Use them in the app once you sign up. The AI ones run an AI model each time you use them. The others adapt to you with fixed rules.

  • Answer Coach

    AI

    Photograph your handwritten answer, upload a PDF or type it. It is marked step by step against the board marking scheme, showing where marks were lost and what a full-marks answer looks like.

  • Diagram checker

    AI

    Draw a labelled diagram, a ray or circuit diagram or a map, and photograph it. See which labels are there, missing or wrong, whether the arrows point the right way, and the marks for the drawing.

  • Hindi writing coach

    AI

    Write a letter, paragraph, notice or e-mail in Hindi. You get marks for content, format and language as the board splits them, the format slips to fix, and a model answer in Hindi.

  • Hint-first AI tutor

    AI

    Stuck on a question? A hint, then a bigger hint, then the full solution, so you learn to solve it yourself. Ask a few study doubts a day and get an answer that sticks to your syllabus.

  • Mistake finder

    Adaptive

    Pick what went wrong. When the same slip comes back in a chapter you get a short tip and a 5-question set to fix it, and your mistakes return for a retest later. Print your mistakes sheet before an exam.

  • My board paper and plan

    Adaptive

    A full paper in the board format with a timer and sections, weighted towards your weak chapters, and a study plan that spreads the chapters over the days left and moves missed ones forward.

AI can make mistakes: check with your teacher, and your teacher's word comes first.

Your first 10 AI markings each month are free.

Plus 2 full board papers a month and 5 tutor doubts a day. No card needed.
