Free Online Grammar Checker & Writing Assistant
Beyond Spellcheck
FreeGrammarKit catches what spellcheck misses: subject-verb agreement errors, misplaced modifiers, passive voice overuse, wordiness, comma splices, and style inconsistencies. Errors are highlighted inline with explanations and suggested fixes.
Readability Scoring
The readability panel shows your text's Flesch-Kincaid grade level, reading ease score, average sentence length, and word complexity. Aim for grade 8-10 for general audiences — lower for marketing copy, higher for academic writing.
No Word Limit & No Sign-Up
Paste entire essays, reports, or emails. FreeGrammarKit processes everything client-side — no word limit, no account required, no text sent to any server. Your writing stays completely private.
