Stop guessing what
examiners actually want.
Paste a past paper question and mark scheme. Markly marks your answer like an examiner, then explains every point in plain English - not textbook language.
Three steps, no setup.
No accounts to mark a question. No PDFs to dig through. Just the question, the mark scheme, and your working.
Paste or photograph
Drop in the question, the mark scheme, and your answer - as text, a photo, or a PDF straight from the paper.
Get marked like an examiner
See exactly which mark scheme points you hit, which you missed, and why — with a mark out of the total.
Ask until it clicks
Select any line of the explanation and ask a follow-up. The tutor remembers the full question and your answer.
It doesn't stop at the mark scheme.
Every question you get marked feeds a tutor that remembers it, a flashcard deck built from your mistakes, and a proficiency map of every topic you've touched.
Highlight a line. Ask why.
Select anything in the mark analysis and ask a follow-up — the tutor already has the full question, mark scheme, and your working in context. Or skip straight to "Explain Answer" before you've even attempted it, and "Check My Answer" once you have.
def solve_modulus(a): # Solve 2|2x - a| < |x + 3a| # Case 1: positive values return (-a/5, 5*a/3)
Every mistake becomes a flashcard.
Markly turns the exact points you dropped into a personal deck — Anki-style, graded easy, medium, or hard, each worth different XP. Get something wrong twice and a "boss fight" MCQ shows up to make sure it actually clicked.
Watch weak topics turn strong.
Every check earns XP, boosted by a streak multiplier up to 2×. Behind the scenes, each topic you touch — not just each subject — gets its own proficiency score, so you know exactly what to revise next, not just how you're doing overall.
Built around how CIE actually marks.
Trained on command words, AOs, and the specific conventions examiners use — not generic AI tutoring.

Every mark scheme point checked off or flagged, with a clear reason for what was awarded and what wasn't.

What examiners are actually looking for, in language that sounds like a tutor — not a textbook.
