How it works
Three steps. One better draft.
No setup, no waiting on a teacher. Upload, read your feedback, and fix the things that move your grade.
02
Get a grade & feedback
In under a minute you get an estimated grade plus detailed, actionable feedback mapped onto your document.
03
Fix it first
Work through the colour-coded notes, fix the things that move your grade, and submit a draft you feel good about.
The feedback is the point
Not just a number — a map of what to fix.
Every pre-grade comes back colour-coded and annotated, so you can see your strengths and your gaps at a glance and act on them right away.
- An estimated grade — treated as a starting point, never a promise.
- Line-level annotations highlighted right on your text, not in a separate report.
- A prioritised fix list so you know what to tackle first.
- Works across subjects — essays, lab reports, problem sets and more.
How your feedback is colour-coded
The same legend across every subject.
Well done — keep doing this
Could be stronger — worth another pass
Needs work — fix before you submit

I caught a weak thesis before my teacher ever saw it. Went from a B- to an A-.

The colour-coded markup is so much clearer than a number at the top of the page.

I use it for lab reports now. It tells me exactly which section is thin.

Honestly feels like having a tutor read my draft at midnight before it is due.

FAQ
Questions, answered.
No — and that is important. PreGrader gives an estimated grade as a starting point to help you improve. Your real grade depends on your teacher and their rubric. Think of it as a study aid, not a promise.
Essays, lab reports, problem sets, history papers and more. Pick the subject, upload your file, and add any rubric or instructions your teacher provided so the feedback fits your assignment.
Most pre-grades come back in under a minute, complete with an estimated grade, annotated markup, and a prioritised list of what to fix first.
No. PreGrader gives you feedback on work you already wrote — like a tutor or peer reviewer — so you can revise it yourself. It does not write your assignment for you, and we encourage following your school's academic integrity policy.
Your documents are yours. We use them only to generate your feedback and grade history, and never share them. You can delete a pre-grade from your history at any time.
Yes. Free stays free forever, and paid plans can be cancelled at any time — you keep access through the end of your billing period.
