AI Grading Assistant

Paste an essay or exercise — the rules engine checks typos, punctuation, sentence length, word variety and structure, with the rule behind every note.

Grading runs entirely in your browser — nothing is uploaded.

⚖️ AI-assisted grading is rule-engine output — for reference only, not a substitute for a teacher.
