Marks handwritten maths answer scripts in Bangla and English, with step-by-step feedback for every student

Overview

Problem

Secondary school teachers in Bangladesh often teach classes of 60 to 80 students and mark every test by hand, so a single exam can take two weekends. Feedback comes back weeks later as one number, and students never see which step of a long answer went wrong. Coaching centres preparing students for board exams face the same problem with weekly mock tests.

Solution

Teachers photograph answer scripts with a phone; Porikkha reads handwritten Bangla and English, including equations and diagrams, and marks each step against the teacher's rubric. Uncertain answers go to the teacher for a quick check, and every student gets a printed or SMS summary of the steps they missed. Class reports show which topics need re-teaching before the next test.

Target market

Private schools, madrasas teaching the general curriculum and coaching centres in Bangladesh, roughly 30,000 institutions, with West Bengal and Nepal as the next markets.

Business model

Per-student annual subscription (BDT 250–400) sold to schools and coaching centres, plus a free teacher tier capped at 100 scripts a month.

    Good on clean scripts, shaky on poor photos

    On clear photos the step marking is impressive, including Bangla conjuncts mixed with algebra. On the blurred, low-light photos teachers actually take in classrooms, the handwriting confidence drops and far more scripts get flagged. The 94% agreement figure probably reflects the better-lit schools.

    Reply from Tahmina Chowdhury, CEO

    That matches our data. We now ask for a retake when a photo is too dark, and part of this round goes into training on classroom-quality images.

    Teachers get their weekends back, and keep the final say

    A maths teacher in Halishahar told me she used to spend two weekends marking each mid-term. With Porikkha she checks eleven flagged scripts and approves the rest in an evening. The step-level feedback is the real product: students finally see where an answer went wrong.

    Clear unit economics question to answer

    The product works and renewals are strong. At BDT 250–400 per student, revenue per school is small, so the sales motion has to be cheap and the free teacher tier has to convert. Conversion from free teachers to paying schools is not measured closely yet, and I would put that number at the top of every board pack.

    Built around how Bangladeshi teachers already work

    Rubrics follow the board exam marking scheme, results print for parents without smartphones, and the free tier lets individual teachers try it before the school pays. Shahana trained teachers for years, and the class reports read like something written for a staff room. Physics and chemistry are not supported yet.
