Free Spell Checker
Catch spelling and grammar mistakes in real time, with plain-language explanations for each one. Paste your text, run the check, and fix issues with a single click.
How this spell checker works
A quick pass that explains itself, not just underlines.
Paste your text
Drop in an email, essay, or message — anything from a sentence to a few paragraphs.
Run the check
It scans for a built-in list of commonly confused and misspelled words, doubled words, and stray spacing.
Review and fix
Each flagged issue comes with a plain-language explanation and a one-click fix.
What this checker catches
Commonly misspelled words
Words like "occured," "definately," and "recieve" get flagged with the correct spelling suggested.
Mixed-up word pairs
Slips like "should of" instead of "should have," or "your" instead of "you're," are flagged with a short explanation.
Doubled words
Catches accidental repeats like "the the" that are easy to miss while proofreading your own writing.
Extra spacing
Flags double spaces and stray spaces before punctuation that slip in while editing.
What this tool isn't
Not a full grammar engine
It checks against a curated list of common mistakes rather than parsing full sentence grammar, so it won't catch every subtle error a professional editor would.
Not aware of names or jargon
Proper nouns, brand names, and technical terms may occasionally get flagged — use your judgment on those.
Not a replacement for reading it aloud
Reading your text out loud still catches awkward phrasing that no automated checker will flag.
Frequently asked questions
Is my text sent to a server?
The checking happens entirely in your browser against a built-in dictionary that’s part of the page itself — nothing is sent anywhere, and it even works offline.
Does it catch every possible mistake?
No. It covers frequently misspelled words, doubled words, spacing slips, words one letter off from a common English word, and a handful of common grammar slips like subject-verb agreement (“I goes”) and a/an usage — not full grammar parsing or style suggestions.
Can I fix an issue with one click?
Yes, each flagged issue has a “Fix” button that applies the suggested correction directly in your text.
Does it work for languages other than English?
It's built around common English misspellings, so results for other languages won't be reliable.
Will it flag names or technical terms?
Occasionally, since it doesn't recognize proper nouns or jargon — use your judgment before applying a suggested fix to those.
