What it catches
Every mark that trips people up, plus the spelling and capitalization errors that ride along with them.
Commas
One comma changes the whole sentence. "Ma’am your order is ready" becomes "Ma’am, your order is ready." We catch the missing ones and remove the ones that break the rhythm.
Periods
A sentence that never ends is a sentence nobody finishes reading. We flag fused clauses and show you where the full stop belongs.
Apostrophes
Settle the its/it’s question for good. Contractions, possessives and plural nouns all get checked against the rule, not against habit.
Hyphens and dashes
Compound words need to read as one unit. We keep "self-driving car" hyphenated and stop en dashes standing in for hyphens.
Question marks
A question dressed as a statement confuses the reader. "Wheres your phone." becomes "Where’s your phone?" with both problems fixed.
Colons and semicolons
Two marks, two jobs. Colons introduce, semicolons join. We check that each one is doing the work it was chosen for.
Quotation marks
Dialogue and quoted material follow strict conventions. We check the pairing, the nesting and where the surrounding punctuation sits.
Spelling
Typos slip past every proofread. "Beleive" becomes "believe" and "definately" becomes "definitely", spelled for whichever English you picked.
Why writers use it
It costs nothing
No account, no trial, no credit card. Paste your text and check it as often as you need.
Six varieties of English
Write "color" or "colour" and have it come back right. Pick American, British, Australian, Canadian, New Zealand or South African before you check.
You stay in control
Nothing changes until you say so. Hover any underline to see the fix, accept the ones you want, ignore the rest.
Your text stays yours
No account, so nothing is attached to you. Your writing is checked and discarded on our side, and your recent checks are saved only in your own browser, where you can clear them any time.
Who it is for
Students
Essays, term papers and theses get marked down for mechanics before anyone argues with your ideas. Clear those errors first.
Professionals
A misplaced comma in a client email undercuts everything above it. Check anything going out with your name attached.
Writers and editors
Catch the errors your own eye slides over after the fourth read of the same paragraph.
People writing in a second language
English punctuation follows rules that are rarely taught directly. Each suggestion explains what changed and why.
