Practice items on ESSAi are AI-generated or ESSAi-authored in exam formats (for example DSE / TSA / HKAT format), with reference to the EDB curriculum. They are not HKEAA examination papers, sample papers, practice papers or marking schemes, and are not original exercises from any textbook or commercial assessment publisher.

English teacher pain · Essai solution
Marking 40 English essays = late-night week with endless red pen.

General AI markers score like SAT / IELTS, not like HK DSE or TSA.
HK-tuned model aligned with HKEAA DSE Paper 2 (CONTENT / LANGUAGE / ORGANIZATION).
Handwritten drafts need typing; cursive and spelling errors confuse OCR.
99% English handwriting OCR including cursive; spelling errors flagged separately, not as OCR errors.
