You have lost a paper before. You will lose one again.
It happens to every department. A student hands in a paper, it goes into a pile, the pile goes into a folder, the folder goes into a drawer, and three weeks later nobody can find it. The student asks for their result. You tell them you are still grading. You spend an hour searching. If you find it, you grade it that night. If you do not, you have a bigger problem.
Then there is the scattered system problem. Some grades are in the LMS. Some are in a spreadsheet that one teacher maintains. Some are written on the front of the paper and never entered anywhere. When it is time to compile results, you chase down every teacher, beg them for their grades, merge three spreadsheets that do not quite line up, and hope you did not miss anyone.
And the progress problem. A parent asks how their child is doing. You do not know because the papers are with the teacher, the teacher has not finished grading, and there is no way to check. You tell the parent you will get back to them. You forget. They call again.
An online grading platform fixes all of this. Submissions, grading, feedback, and reporting live in one place. Teachers grade from anywhere. Students get feedback instantly. Progress is visible in real time. Nobody loses a paper because there is no paper to lose.
What Is an Online Grading Platform?
An online grading platform is a central system where submissions, grading, feedback, and reporting all live together. Students submit work online or you upload scanned papers. The platform reads the submissions, applies your rubric, suggests marks, and lets your teachers review and approve from anywhere with an internet connection.
GradeLab lets your teachers add custom instructions so the AI grades the way your institution expects. Tell it to be strict on units in physics. Tell it to award method marks even when the final answer is wrong. Tell it to follow the specific rubric your department approved. The AI applies your instructions on every paper, consistently.
The platform keeps everything in one place. No more lost papers, no more scattered spreadsheets, no more chasing teachers for grades. One system, one source of truth, accessible from anywhere.
How an Online Grading Platform Is Different from Paper and Spreadsheets
| What changes | Paper and spreadsheets | GradeLab online grading platform |
|---|---|---|
| Lost papers | Papers go missing from piles, folders, and drawers | Every submission is stored digitally. Nothing gets lost. |
| Scattered grades | Grades spread across the LMS, spreadsheets, and paper | All grades in one platform, one source of truth |
| Progress tracking | You chase teachers to find out what is done | Real-time progress visible to everyone who needs it |
| Where you grade | At your desk, with the paper pile | From anywhere, on any device with a browser |
| Student feedback | A mark on the paper, handed back weeks later | Specific feedback delivered instantly once approved |
| Reporting | You merge three spreadsheets and hope they line up | One-click reports with full breakdowns and audit trails |

An Online Grading Platform That Centralises Everything
GradeLab brings submissions, grading, feedback, and reporting into one platform. No more lost papers, no more scattered spreadsheets, no more chasing teachers for grades.
Submissions in One Place
Students submit online, or you upload scanned papers. Every submission is stored digitally, organised by class and assessment. Nothing gets lost.
OCR for Handwritten Papers
Upload scanned handwritten papers or phone photos. GradeLab reads the handwriting, maps answers to questions, and prepares every response for grading.
Rubric Application with Custom Instructions
Upload your rubric. Add custom instructions in plain English. Tell the AI what to accept, what to penalise, and how strict to be. It follows your rules on every paper.
Grade from Anywhere
Your teachers log in from any device with a browser. They review suggested marks, override anything they disagree with, and approve. No more being tied to a desk with a pile of papers.
Real-Time Progress Tracking
See which assessments are graded, which are in progress, and which are waiting. No more chasing teachers for updates. The progress is visible to everyone who needs it.
Instant Feedback for Students
Once a teacher approves the results, students receive question-level feedback instantly. No more waiting weeks for a paper to come back with a number on it.
Confidence-Based Review Queue
Low-confidence answers are flagged and sent to the review queue. Your teachers focus on the uncertain answers, not the straightforward ones. Every suggestion includes visible AI reasoning.
One-Click Reporting
Generate reports with grade distributions, question-level breakdowns, and audit trails. Everything the exam office or department head needs, in one click.
Full Audit Trail
Every decision is recorded: the original answer, the rubric applied, the AI reasoning, teacher overrides, and the final mark. When a student or parent asks why, you have the answer.
Grade It Like You Would. From Anywhere.
Every teacher has their own way of grading. Maybe you are strict about showing working in maths. Maybe you give credit for a good attempt even if the answer is wrong. Maybe you deduct marks for missing units, or maybe you let it slide if the physics is correct.
GradeLab lets your teachers add custom instructions so the AI grades the way your institution expects. You write your rules in plain English, and the AI applies them to every paper in the batch. Here is what that looks like:
"Award full marks for method even if the final numerical answer is wrong. Deduct one mark only if the student did not show any working."
"For essay questions, give credit for original argument structure. Do not penalise for spelling if the meaning is clear. Penalise only if the argument lacks evidence."
"In physics, always check units. Deduct half a mark if the answer is numerically correct but missing units."
"For this exam, accept both method A and method B for question 7. They are alternative valid approaches."
The AI follows your instructions on every paper, consistently, whether your teachers are grading from their office, their living room, or a different campus. No fatigue, no inconsistency, no lost papers. You still review and override anything you want. But the starting point is your standard, not a generic one.

Online Grading Platform FAQ
What is an online grading platform?
An online grading platform is where your entire grading workflow lives in one place. Submissions, grading, feedback, and reporting all happen in the browser. No more lost papers, no more grades scattered across spreadsheets, no more wondering where you left off. GradeLab is an online grading platform with AI grading built in, so you get automation and human review in the same system.
Can I grade from anywhere with an online grading platform?
Yes. As long as you have a browser, you can grade from your desk, from home, or from your phone. Your progress is saved automatically. When you log back in, you pick up right where you left off.
Does GradeLab replace our current grading setup?
It depends on what you are using now. If you are grading by hand or with spreadsheets, GradeLab replaces the chaos with one platform. If you are using an LMS, GradeLab integrates with it via API so you can keep your existing workflow and add AI grading on top.
Can I add custom grading instructions on the platform?
Yes. You write your rules in plain English and the platform applies them on every paper. For example: "give credit for correct method even if the final answer is wrong" or "deduct marks for missing citations." The AI follows your instructions consistently on every submission.
Is my grading data safe on an online platform?
Yes. All data is encrypted in transit and at rest. Only authorised staff can access your grading data. Student submissions are processed through secure channels and are not shared with third parties.
Can multiple teachers use the platform at the same time?
Yes. Multiple graders can work on the same assessment simultaneously. The platform coordinates assignments, applies the same rubric, and surfaces discrepancies for moderation. Everyone sees the same data in real time.

Thomas Braun
Lecturer, Pure Mathematics, Germany
My students write formal mathematical proofs. On a convergence proof question, GradeLab correctly identified whether the quantifier structure was right, whether the chosen bound worked, and where the logical chain broke. It did not just check the final line. That is the part that matters.
Dr. Isabelle Fontaine
Associate Professor, Theoretical Physics, France
GradeLab evaluated a wavefunction normalisation problem across 140 papers and correctly flagged eleven cases where students had a correct final integral but had used the wrong boundary condition. That is precise, subject-aware marking.
Prof. James Fletcher
Mechanical Engineering, Thermodynamics, USA
GradeLab evaluated a question on entropy generation in a throttling process and correctly identified which students had omitted the system definition, which had applied the steady-flow energy equation incorrectly, and which had confused entropy change with entropy generation. That distinction matters in this subject and it caught it reliably.

Science Teacher, Lycée Henri IV, Paris
Before GradeLab, I spent every Sunday grading papers instead of being with my family. Now I upload the batch on Friday evening and by Saturday morning, every student has already seen their feedback. That part still surprises me.
Maria Santos
Teacher, Escola Internacional de Lisboa
I teach four classes with 35 students each. I genuinely could not keep up with grading. GradeLab didn't just save me time - it gave me back the ability to actually know where each student was struggling.
James Eriksson
Director, Nordic Learning Centre, Stockholm
We run a centre with 400 students preparing for university entrance exams. The volume of grading was unsustainable. GradeLab handled our entire mock exam cycle - 400 papers graded, scored, and pushed to students in one night.
Sarah Mitchell
Head of Academics, Wellington Grammar School
We trialled several edtech platforms before GradeLab. What stood out was that it wasn't just grading software - the student feedback loop was instant, and the quality reports for governors were exactly what we needed.
Prof. Clerk Anderson
Controller of Examinations, University of Edinburgh
At the university level, consistency in marking is a compliance issue, not just a quality one. GradeLab's audit trail and standardised scoring gave us exactly the documentation we needed for our accreditation review.
