What is a grammar checker?
A grammar checker reads your text and corrects grammar, spelling, and punctuation mistakes. Humanit goes further than autocorrect: it returns the fixed text and a categorized list of every edit — grammar, spelling, punctuation, clarity, or style — with a one-line reason for each, so you understand the correction instead of just accepting it.
Four correction modes
Light fixes only undeniable errors and touches nothing else. Standard fixes errors and smooths obvious awkward phrasing. Strict polishes thoroughly for readability. Clarity restructures run-ons and cuts redundancy. Your voice and meaning stay intact in every mode.
Proofread before you submit
Run essays, emails, applications, and posts through the checker for a clean final pass. Because every change comes with a reason, it doubles as a quick way to spot the mistakes you keep making.
