Marking assistant for teachers · not on any app store yet
Import a Google Form, scan a stack from the photocopier, or photograph papers one at a time. Back come question-by-question marks, a written reason for every deduction, and feedback a fourteen-year-old will actually read — all of which you can override.

Times are for a class of thirty
Most teachers settle on two of them — one for quizzes, one for real tests on paper. Pick a route to see what it costs you in minutes.
~2min
for a class of thirty, start to finish
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
This is the paper route — a stack off the photocopier, thirty papers deep. Scroll and it moves through it one step at a time.
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.
30 papers · one document feeder · one PDF.
In a browser it covers the printed “Name:” line, not the handwriting.
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.

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.
Q2 — right method, arithmetic slip in the last line.
On every plan, including free.
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.
Hand-drawn diagram — flagged for the teacher, not scored on a hunch.
The teacher decides the grade. Always.
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.
| Paper | Mark | % |
|---|---|---|
| 01 | 17½ | 88% |
| 02 | 15¾ | 79% |
| 03 | 19 | 95% |
| 04 | 12½ | 63% |
| 05 | 16¼ | 81% |
| 06 | 18½ | 93% |
Nothing is sent to a gradebook, a student or a parent.
Nothing is sent on your behalf.
Turn one over
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.
Q2 — right method, arithmetic slip in the last line. Show the substitution next time.
Q2 · Solve 3x + 7 = 25
Keep scrolling →
Method correct throughout. Arithmetic slip on line two: 25 − 7 is 18, not 32.
Write the subtraction on its own line before you divide.
Q3 · Mettez au passé composé : « Je vais au cinéma. »
Keep scrolling →
Right tense, wrong auxiliary: « aller » takes être, and the participle agrees — « je suis allé », or « allée ».
Aller is a VANDERTRAMP verb. Say the sentence once with « suis » and it will stick.
Q5 · Give one cause of the 1929 crash and explain it
Keep scrolling →
Names a real cause — buying on margin — and runs the mechanism in both directions. Full marks.
Use the term “buying on margin” and the same answer earns its keep in the exam.
Q7 · Sketch the forces on the block
Keep scrolling →
A hand-drawn diagram. Not scored on a hunch — handed back for a teacher to mark.
Flagged as “requires teacher marking”.
Also in the app: answer keys, scanned once or learned from the first paper of a stack · Ontario KTCA categories and curriculum expectations for your region · gradebook CSV and Google Drive export · drafted quizzes, worksheets and lesson plans.
Rules, not preferences
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.
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.
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.
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.
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.
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.
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.
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
You would be handing us other people’s children’s work. Here is exactly what happens to it.
On iOS and Android, on-device text recognition finds identity fields — Name:, Student:, Student ID: — and paints them solid black in the uploaded copy. The unaltered page stays on your phone, and the name files the result under the right student.
Never by name. The name column is never transmitted, known student names are scrubbed out of the answer text, and multiple-choice questions never leave the device at all.
Images are marked and discarded; what is stored is the result. No ads, no analytics SDK, no student accounts. Delete your account in the app and every result, class and key goes with it, irreversibly.
UMarkless reduces exposure substantially. It does not make a scanned page anonymous, and no vendor should claim otherwise. Subprocessors, legal footing, retention and every known gap are in Security and compliance.
10% goes to charity, off the top
Every paid plan gives 10% to charities that help kids learn — not a marketing line, it comes 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.

The password is typed in the app
Classes, answer keys and every marked test stay with the account rather than the device. Sign in somewhere else and they are already there.
There is no server behind this page — it is a static file. Your email travels across to UMarkless in the address bar, and the app’s own sign-in screen takes the password. Nothing here asks for one, and nothing here could receive it.
Create Account sits directly under the sign-in button in the app and asks for an email and a password. Plans start on a free trial. Google, Microsoft and Apple sign-in appear there too, when the server has them switched on.
In a browser the name blackout runs here on your own machine, but it reads the printed “Name:” line rather than the handwriting, so it covers that whole line. On a page where it finds no printed label, nothing is covered and the app tells you. Read the limits.
An active project, submitted to the RevenueCat Shipaton 2026, and not on any app store yet. Ask to be told when it is — or, if you are a school, to read the compliance write-up first.
