What we believe about AI in marking
A suggestion is not a decision
GradeOrbit never finalises a grade on its own. It reads work against the mark scheme you supply, proposes a mark with the evidence attached, and waits for you to approve, change, or reject it.
Your mark scheme, not a generic rubric
Marks come from the criteria you upload, aligned to AQA, Edexcel, OCR, Eduqas and WJEC across KS3, GCSE, A-Level, BTEC and Functional Skills. Maths is graded gate by gate, so correct working still earns method marks when the final answer is wrong.
AI detection is an indicator, never proof
Writing changes as a pupil learns. Our detection compares a piece against that pupil's own earlier work and flags a marked change — a reason to have a conversation, not evidence of wrongdoing.
No training on your work
Work is processed by Google's Gemini models under terms that rule out training on it, and is never used to train any AI model.
How data is handled depends on the account
These three postures are genuinely different by design. We do not describe one using the other's language.
Individual accounts
Uploaded student work is never saved to our database. You can black out names and personal details before processing, and pupils are labelled “Student 1”, “Student 2” — we never try to detect a real name.
School accounts
The deliberate inverse: work is retained under a Data Processing Agreement, so staff can return to a marked script and the school gets analytics. Retention is windowed and wiped when it expires or when a school leaves.
Student accounts
A learner's own work is saved to their own account so they can track progress across drafts, and is deleted with the account whenever they choose. A GradeOrbit mark is a study estimate — never an official or certifying grade.
Full detail lives in the Privacy Policy and the Transparency Pack, which is generated from the same source of truth the product uses.
