GrammarLens — AI Grammar Checker
Every correction comes with the reason behind it
What is this project?
Most grammar tools fix your sentence and move on. GrammarLens teaches while it corrects. Text is scored out of 100 with a plain-language verdict ("Looking good — 3 issues to review"), and every problem is underlined in place so the writer sees it in context.
Each suggestion is a before → after pair with a written explanation of the rule: why "gone" should be "has gone" (present perfect after "she" for a recently completed action), why "dont" should be "doesn't" (correct form to use with "he"), why "nothing" should be "anything". Fixes can be applied one at a time or all at once, and the corrected text copies to the clipboard in a single click.
The editor keeps a live character count and a clean toggle between reviewing and editing, so the writer stays in flow.
