Map Every Exam Error to the Source That Fixes It — Free
Each recurring mistake gets the sources behind it from a numbered key, and the label shows which rows still have nothing behind them — the gaps that cost marks. The free tier is the whole tool: every field, every state, the state link and one complete un-watermarked run. The one-time layer adds the printable copy and the local history shelf; it never removes or degrades the free result.
1 · Set the error label
FIRST-LOAD · sample record filed, free run untouched
Data note: Everything is computed in this browser tab. Nothing you type is uploaded, and nothing is stored on our servers. Redact names and identifying details before you paste anything sensitive, and check the output against the named source before you act on it.
2 · Read the designed exam error source label
GratisAI mapped every recurring exam error to its source and flagged the one with nothing behind it.
Boundary: This maps your own marked errors to material you already have; it does not mark work, predict grades or replace teaching. Marking schemes and grade boundaries come from the awarding body and your school — confirm any result with them.
One-time layer · $4
