Grade it. Understand it. Get ready for the next one.
Slate grades every answer sheet accurately, diagnoses exactly where each student is struggling, and hands teachers and students a clear next step — so preparation for the next exam starts the same day, not two weeks later.
Marking is slow. The insight is thin. Nothing prepares the student for next time.
The same booklets. A different outcome.
Same booklets, fed straight to Slate. It grades and turns them into a concept map before the next class starts.
From booklet to graded result — how a real exam moves through Slate.
Worked example: a Grade 8 Science unit test, 120 students.
Tested against handwriting exactly like this — not an idealized version of it.
Handwriting is the single biggest reason schools hesitate on automated grading. Slate's grading engine is tested and tuned against the messiest real answer sheets before it ever touches a live exam:
Test in the morning, insight by the evening. Same day.
No two-week wait for marks, no separate reporting cycle. The whole loop — test, scan, grade, diagnose — closes before the school day ends.
Graded like an examiner — every single time.
This is the part schools care about most: is the grading actually accurate enough to trust? Here is exactly how it works.
Build a paper aligned to your board — before you grade one.
Pick the chapters and the difficulty. Slate assembles the paper from your board's own textbooks and study materials — with a rubric ready before the first booklet is collected.
What Slate removes — and what every role gains.
Slate does not add work. It removes the delays, guesswork, and bias that sit between a test and the teaching that should follow.

Fairness, not replacement.
Slate does not replace the teacher's judgment. It removes the factors that should never have influenced marking in the first place — tiredness, handwriting, familiarity, time pressure. Paper 1 and paper 35 get identical attention. Handwriting quality does not influence the score. No student history or relationship affects the evaluation. The teacher still makes the final call, and every override is logged. The starting point is always fair.
Pinpoint exactly where understanding breaks down.
"58% in Maths" is a score, not a plan. Riya sets up equations fine. She drops marks on the second conversion step — that's the concept to re-teach.
A task list lands the same day the exam is graded.
Not just a score. Slate turns every gap into the next concrete thing to do — for the student, and for the teacher planning tomorrow's class.
A view for every decision-maker.
The same test, shaped for the person who needs to act on it.
Built for schools and pre-universities — with university next.
Built for K–12 schools and pre-university / junior colleges today. Undergraduate university is next on the roadmap, on the same grading engine.
K–12 package
CBSE has first priority today, for regular assessments across primary, middle, and secondary grades.
PU / Junior college
For high-stakes PU and junior-college streams preparing for board and entrance exams.
One grading engine. Every board you actually run.
CBSE has first priority — it's who Slate is built closely with right now. The same rubric-bound grading engine is built to work across other boards too, and both exam formats — OMR and handwritten theory.
CBSE
The board Slate works with most closely today — grounded in the NCERT curriculum, for the everyday unit tests and term exams CBSE schools run all year.
ICSE / ISC
The same grading engine, applied to CISCE's answer style and marking conventions.
Cambridge IGCSE
For international and Cambridge-affiliated schools running IGCSE alongside or instead of CBSE.
Pre-University / Junior College — State Board
For PU colleges and junior colleges preparing students for board and entrance exams — both exam formats, one pipeline.
A struggling cohort shows up in the marks weeks before anyone notices. Slate surfaces it while there's still time to teach it again.
Everything you'd want to know before saying yes.
If something below still isn't clear, that's what the 30-minute walkthrough is for — but most schools find their answer here.
How accurate is the AI grading, really?
Every mark is generated by frontier vision-language AI models, checked against a rubric — either the one your subject teacher provides, or one Slate builds itself from the NCERT textbook and the concept being tested. Nothing is graded "by feel." And nothing is final until your teacher has seen it: every mark shows its reasoning and can be corrected in one click before it reaches a report card. The starting point is consistent and rubric-bound; the teacher's judgement is always the last word.
Does Slate replace teachers, or the CBSE evaluation process?
No. Slate replaces the hours a teacher spends hand-marking, not the teacher's judgement. Grading, evaluation, and report cards remain entirely under your institution's control — Slate proposes the grade and the diagnosis, your subject teachers confirm or correct it. It does not change how CBSE examinations or internal assessments are conducted.
What if a subject teacher doesn't have a rubric ready?
Slate builds one — reasoning through the relevant NCERT chapter and the concept the question is testing, the same way a subject expert would set a marking scheme, before a single booklet is graded. If you'd rather use your own, upload it and Slate grades against that instead.
Is Slate built around the CBSE curriculum specifically?
CBSE has first priority — it's who Slate is built closely with today, for CBSE-affiliated institutions in India and abroad, with the examination builder and grading engine grounded in NCERT textbooks and CBSE marking-scheme conventions. It isn't the only board the engine is built for: the same rubric-bound grading extends to ICSE/ISC and Cambridge IGCSE too — see the Boards section for what's supported on each.
Do we need to buy a scanner or change how we run exams?
No. Your regular tests, unit exams, and answer booklets stay exactly as they are. You can keep using whatever scanner or scanning process you already have — or, if your school needs one, Slate can provide a scanner as part of the package. Either way, scans link straight to Slate and are matched to each student automatically.
How much teacher time does this actually save?
A teacher (or team) hand-marking 120 papers at roughly 5 minutes each typically spends about 10 hours. With Slate, those same 120 booklets are graded in the background at roughly 45 seconds each — about 90 minutes, unattended — and teachers spend about 70–100 minutes reviewing and confirming results, the same day the test is conducted. Across a full year of exams, that adds up to well over 50 hours per teacher returned to actual teaching.
How is this different from the marks/analytics tools already on the market?
Most tools start after a teacher has already marked the paper — they just total the scores into a spreadsheet. Slate starts earlier: it does the grading itself, question by question, against a rubric. Because the grading is accurate at the source, the analysis underneath — concept gaps, readiness scores, task lists — is trustworthy instead of a guess built on inconsistent human marking.
What happens to a struggling student, beyond the score?
Every result opens with what the student got right, names the gap plainly and without judgement, and closes with one small, achievable task — not a wall of red ink. Parents and class teachers are notified early, while there is still time to help, not at report-card time.
Is our student data secure?
Yes. Data is scoped to your institution's account, access is role-based (only the staff, students, and parents you grant access to can view it), and everything — booklets, scores, and observations — is stored digitally rather than in loose paper registers that can be lost.
How long does it take to get started?
Send us a recent test as a PDF and we'll show you exactly what Slate surfaces on your own data — no setup required for that first look. Full onboarding for a term or a subject typically runs a few days, tailored to your institution's size and current process.
