We help teachers give every student feedback the moment it matters.
ren. marks every script with teacher-level accuracy and turns it into a next step. No student waits weeks to improve. No teacher loses a weekend to marking.

The whole feedback loop, in one place.
Grade with precision
Every mark anchored to the exact work — the snippet, the question, your scheme. You review, you sign off. ren. just does the hours.
Observation is correct: brick-red Cu2O precipitate. However, the organic product drawn is not correct/clear for the oxidation product of glucose (should be the corresponding carboxylate/aldonic acid). −1: incorrect product
Actionable insights, not just grades
The report you'd write if you had the time — every student's strengths, gaps, and next step. The whole cohort at a glance, each student up close.

median 68%The cohort handled recall and structured calculation well, but lost the most marks on application questions needing multi-step reasoning. Q5 and Q10 are the clearest re-teaching priorities before the next assessment.
Sharper the more you use it
Every grade you confirm and every edit you make teaches ren. your standards — your rubric, your tone, the way you mark. Over time, it marks like you.

We don't just hand you software. We partner with you.

Frequently asked questions
All of them. Our humanities automarking is the most mature — calibrated to your department's rubrics for structured and extended-response questions. Our STEM companion extends the same marking to every other subject.
Today we run across English, General Paper, the humanities (econs, history, geography), the sciences (physics, biology, chemistry), math, and mother tongue.
ren. is customised per syllabus — O-Level, A-Level, IB, PSLE — and then calibrated to each school's own pedagogy.
Both go together. ren. doesn't mark to a generic standard — it layers in your school's own past papers, answer schemes, model answers and marking frameworks, then learns each teacher's style from the edits they make.
Every engagement starts with a benchmark report: we mark a sample of scripts your teachers have already graded and show you exactly how closely ren. matches them.
In structured subjects we've reached up to a 98.4% match with human markers, and the more your teachers correct, the closer the marks and comments track their voice and your department's standards.
Your school's data is separated by access controls in the application. Accounts belong to your school and requests are scoped to it, so your corpus, your students' work and your teachers' calibration aren't visible to any other school, and are never reused beyond your engagement.
Data is hosted in Singapore and encrypted in transit, and uploaded scripts sit in private storage reachable only through short-lived signed links.
At the end of a pilot or contract, we pledge to delete your data, and we're happy to provide data-handling documentation to support your school's own clearance process.
We start with a free trial. You give us a sample of marked scripts and answer schemes; we return a benchmark report showing accuracy against your own teachers, plus sample feedback.
From there we calibrate and scope a paid pilot.
