Criteria in, evidence out

Every mark traces back to a rule you set. That is the whole design — the tool assists, it never overrules you.

  1. 01

    Your criteria set the rules

    Pick the qualification, exam board, and upload your mark scheme. Add notes, a word-count target, anything you would tell a colleague marking for you.

  2. 02

    The AI reads every page

    Handwritten or typed, uploaded or scanned with your phone. Each page is transcribed and then marked strictly against your rubric — never a vibe.

  3. 03

    You get an explainable grade

    A grade you can interrogate: pinpointed feedback on essays, gate-by-gate marks on maths. Approve it, adjust it, or ask why. The decision stays yours.

One tool, two kinds of marking

Essays and maths are graded differently — because they should be. Switch between them.

Qualitative, and pinpointed

In "A Christmas Carol", Dickens presents the idea of redemption through Scrooge. Dickens allows the reader to envision a change in attitude through this charactor by highlighting his refusal to change. Soon turned into many actions, this is percieved at the beginning of the novel and this extract. This is when Marley warns Scrooge to listen to him through the quotes "I wear the chains I forged in life" and "Hear me!". The use of punctuation highlights a sence of urgency towards the situation through the exclamation mark. The order "Hear me" tells the reader that Scrooge needs to change and how Dickens uses the figure of his best friend to influnce Scrooge. Furthermore, the ghost of Marley acts as a catalyst for Scrooge's transformation. His appearance is described as terrifying, wrapped in chains that symbolise the consequences of greed and selfishness. Through this encounter, Dickens suggests that it is never too late for reedmption, a message that would have resonated deeply with his Victorian audience who valued charity and moral responsibility.

  • Feedback pinned to the sentence it refers to, not dumped at the end.
  • Graded on your mark scheme — GCSE, A-Level, KS3, BTEC, Functional Skills.
  • Spelling flagged, and counted only if your criteria score it.

Same marking. Two ways to run it.

The grading engine is identical. What changes is how student work is handled — and that is a deliberate choice, not a footnote.

Solo & Team

Never saved to our servers

  • Redact names before anything is sent — the black boxes are burnt in, so the original never leaves your device.
  • We never save student work to our database. It’s processed by Google Gemini under a zero-retention agreement, then gone from our side.
  • The only copy that persists is a redacted one in your own browser — so you can pick up an interrupted marking session. It never reaches us.
  • “Student 1”, “Student 2” — we never ask for or keep a real name.
