The marking assistant for teachers

Marking shouldn’t be your life. Mark less, teach more.

A class set of thirty, marked in the time it takes to pour a coffee: a mark for every question, a written reason for every deduction, and feedback your students will actually read. Every mark stays yours to change.

Start marking freeSee how it works

Free to start, right in your browser. No card, no setup.

Where the evenings go

UMarkless gives that time back: a class set of thirty is marked in 2 to 15 minutes, depending on the route, and you check and sign off instead of marking every paper.

Times are for a class of thirty

Take back your week.

The average teacher spends 4.6 of their 41 working hours a week marking (OECD TALIS 2024). There are four ways to hand that to UMarkless. Pick one to see what a class of thirty costs you in minutes.

Google Form or spreadsheet

Quizzes, and anything students type.

Export the Form responses to a CSV and import it. Confirm the detected columns, tap the correct option for each multiple-choice question, and the class comes back marked. Every student’s answer to a written question is marked together in one pass, so the whole class is judged against the same standard.

Multiple choice is marked on the device for free. No API call, no credits.

The first paper of a set is always marked on its own and shown to you before the other twenty-nine go ahead. A wrong answer key costs one paper, never thirty, on every plan, including free.

One class set, start to finish

Scan, split, mark, review, export. Then your evening.

This is the paper route: a stack off the photocopier, thirty papers deep. Scroll and it moves through it one step at a time.

Stage 01

Scan

A stack goes through the copier once.

Thirty papers, one document feeder, one PDF. Nothing is sorted, nothing is renamed, no page is photographed twice. The name field is read on your own device and painted solid black in the copy that gets uploaded. The unaltered page never leaves it.

In a browser it covers the printed “Name:” line, not the handwriting.

Stage 02

Split

It splits back into papers before anything is uploaded.

Boundaries are found on the phone: a printed code in the footer, a “Name:” field near the top, a “Page 1 of 4”. The split is shown to you and only what you confirm is marked. Tell it how many students to expect and it catches the page the feeder swallowed.

Detection uploads nothing at all.

Stage 03

Mark

The first paper is marked alone, and shown to you.

One paper, marked and handed back before the other twenty-nine go anywhere. If the answer key is wrong you find out on paper one. Then the set runs: question-by-question scores, half and quarter marks, and a written reason for every deduction.

On every plan, including free.

Stage 04

Review

You change anything you disagree with.

Every result opens on a review screen with the score, the per-question breakdown and the reasoning behind each deduction. Change a mark and the override is recorded. A hand-drawn diagram, or an answer reached an unexpected way, comes back flagged for you rather than scored on a hunch.

The teacher decides the grade. Always.

Stage 05

Export

Marks leave as a CSV, or a document in Drive.

A gradebook CSV, or a Google Doc written into the folder UMarkless made. That is the whole handoff. UMarkless sends nothing to a gradebook, a student or a parent. You carry the mark forward yourself.

01 / 05

Turn one over

Marked the way you would mark it

Every card is one question. The front is what the student wrote; the back is what came back: the mark, the quarter mark, the reason for the deduction, and something to do differently. You can change any of it.

Then, across all thirty

Mark the whole set and each question shows how many students got it fully right, and the slip that came up most, worst first, so you know what to go over tomorrow.

Right tense, wrong auxiliary. Aller takes être: « je suis allé(e) ».

Aller is a VANDERTRAMP verb. Say it once with « suis » and it will stick.

People borrowed money to buy shares, so when prices fell they had to sell, and selling pushed prices down further.

A real cause (buying on margin) and the mechanism both ways. Full marks.

Teacher
to mark

A hand-drawn diagram. Not scored on a hunch, so it comes back for you to mark.

Flagged as “requires teacher marking”.

Illustrations of marked answers, not screenshots. Half and quarter marks, a written reason for every deduction, and a question handed back rather than guessed at.

Rules, not preferences

What UMarkless will not do

Seven rules the product is built around. Each of them costs something (speed, margin, or a claim we would rather be able to make), and each of them is in the code, not the marketing.

  1. AI suggests. The teacher confirms.

    UMarkless produces a proposed mark. It is never final, and never recorded as final without a teacher looking at it. An overridden result is flagged as overridden. There is no setting that removes the middle step.

  2. Student identity does not go to the AI.

    The model grades the work. It is not told, and does not need to know, whose work it is. The name is read on your own device, blacked out of the uploaded copy, and kept there. On a phone it reads the handwriting itself, in a browser it covers the printed “Name:” line. Imported answers go up keyed by row number.

  3. The first paper of a set is marked alone.

    The pilot paper is marked on its own and shown to you before the other twenty-nine go ahead. Approving the first result is a safety check, not a premium feature, so it happens on every plan including free.

  4. A wrong answer key costs one paper, not thirty.

    That is the whole reason the first paper goes alone. A key that reads the wrong option, a mark scheme out of step with the test: you find out once, on one page, and fix it before the set runs.

  5. It refuses to guess.

    A hand-drawn diagram, an unreadable page, a right answer reached an unexpected way: it says so, and hands that question back, rather than inventing a score. A confident wrong mark is worse than an admitted gap.

  6. Marks are metered, never “unlimited”.

    Plans are credit-based, and credits are weighted by what a paper actually costs to mark. A short multiple-choice quiz costs a fraction of a six-page problem set, and re-marking the same paper is free. Nobody is promised infinity and then quietly throttled.

  7. The limits are written down.

    Redaction is best-effort on name fields, and weaker in a browser than on a phone. There is no SOC 2 report and no signed DPA template yet. One cheap route uses a provider whose terms permit training. All of it is listed, because a reviewer will find it anyway.

Subprocessors, legal footing, retention and every known gap are written out in Security and compliance.

Including the parts that are not perfect

What leaves the phone, stated plainly

It is other people’s children’s work. Here is what happens to it.

  • The name is blacked out before upload

    On the phone, Name:, Student: and Student ID: are found and painted black in the uploaded copy. The original stays on your phone.

  • Imported answers go up keyed by row number

    Never by name. The name column is never sent, and multiple choice never leaves the device.

  • Pages are not kept, and nothing is tracked

    Images are marked, then discarded. No ads, no analytics, no student accounts, and deleting your account deletes everything.

Plans

of every paid plan goes to charities that help kids learn, off the top.

Start on a free trial. Paid plans are credit-based: credits scale with how much work a paper actually takes, so a short multiple-choice quiz costs a fraction of a six-page problem set, and re-marking the same paper is free.
