About PaperYak
Built by people who actually mark essays. We believe students deserve honest feedback — not participation marks.
The Problem We Saw
We spent years marking university essays. Hundreds of them. We saw smart, hardworking students hand in weak work because they had no idea what their examiners actually wanted.
They'd get feedback after the grade was locked in. Too late to fix anything. They'd use expensive proofreaders who just corrected grammar. They'd ask ChatGPT and get generic rubbish.
So we thought: what if students got honest, actionable feedback before they submit? What if they could understand what actually matters to their markers? What if feedback was cheap enough to use on multiple drafts?
That's why we built PaperYak.
An AI tool that grades essays the way real examiners do. Not a plagiarism checker. Not a grammar fixer. Actual feedback on what works and what doesn't.

Built By Academics, For Students

That's why our feedback is specific, actionable, and actually useful. We're not guessing what markers want — we know.
How We Grade Essays
1. Structure & Organization
Does the essay have a clear introduction, body, and conclusion? Is the argument easy to follow? Are paragraphs logically ordered?
2. Argument Quality
Is the main argument clear and defensible? Are claims supported by evidence? Are counterarguments addressed?
3. Evidence & Sources
Is the essay backed up by credible sources? Are citations done correctly? Is the evidence relevant and well-integrated?
4. Academic Tone
Is the language formal and appropriate for university? Are there clichés or informal phrases that undermine credibility?
5. Clarity & Precision
Is every sentence necessary? Are there redundancies, awkward phrasing, or unclear passages? Can it be tightened?
