Grammar Checker
Before an email goes out or a blog post ships, most drafts carry a handful of repeat offenders: “alot” that should be “a lot”, “cant” missing its apostrophe, “recieve” instead of “receive”, and the double-typed “the the”. This grammar pass catches those classics and a short list of commonly-mangled contractions and spellings so your copy reads clean on the first draft review.

What the checker catches
| Category | Examples |
|---|---|
| High-frequency misspellings | “alot” → “a lot”, “definately” → “definitely”, “recieve” → “receive” |
| Missing apostrophes | “cant” → “can’t”, “dont” → “don’t”, “wont” → “won’t” |
| Double words | “the the”, “is is”, “to to”, collapsed to one |
| Spacing around punctuation | “, hello” → “, hello”; “ .“ → “.” |
What it does not catch
- Context-dependent errors: “their” vs “there” vs “they’re”, the correct form depends on meaning.
- Subject-verb agreement: “the list of items are” needs a parser with sentence structure.
- Style issues: passive voice, long sentences, tone.
- Non-English text: the rule set is built for English only.
When to move up to a proper engine
For anything client-facing or long-form, pair this quick pass with a full grammar engine (LanguageTool, Grammarly). This tool covers the highest-frequency typos fast; it is not a replacement for an editorial read.
Tip: run the pass twice
Autocorrect suggestions occasionally collide, fixing “cant” may reveal a nearby error that was hidden. A second pass catches what the first exposed.
Frequently Asked Questions
No. It catches high-frequency typos and missing apostrophes. Grammarly-style full grammar analysis requires a sentence parser and a dictionary several megabytes in size; this tool is the quick-first-pass companion to that.
Those are context-dependent, each spelling is a real English word. Telling them apart requires understanding the sentence meaning, which pattern-based checks cannot do reliably.
Not in this tool. Keep your own find-and-replace list for project-specific fixes such as product names or technical terms, then run this quick pass afterwards.
No. The rules run in your browser and your draft is not sent to any server.
