AI marking software comparison (UK)
A criteria-based table of Feedback Flows versus Top Marks AI, AegisMark, GradeOrbit, Gradescope and MarkMate, sourced from each vendor’s public pages as of September 2026. Honest where we do not lead.

UK schools comparing AI marking tools should weigh mark-scheme flexibility, handwriting support, vocational fit, release governance and pricing, not just marketing claims. This page names major vendors and cites their own public materials; cells marked “Not documented” mean we could not verify the claim on their public site at the time of writing.
Last reviewed: 8 September 2026. Rival features change; re-check vendor sites before procurement. Also read Choosing AI marking software in the UK and our AI marking for UK schools page.

Where Feedback Flows wins, and where it does not
Choose Feedback Flows when you need bring-your-own schemes (including vocational and EPA), handwriting OCR, documented release governance, published individual pricing, and a platform that also covers integrity, classes and reporting.
Choose a board-locked specialist if your only requirement is pre-built GCSE/A-Level board tools with published examiner-correlation percentages. We do not publish that benchmark today and we do not ship a built-in board library.
We also do not offer native SIMS/Arbor/Bromcom sync today. Those are honest gaps; a table that claims to win every row is usually marketing, not procurement evidence.
