Tools

Every tool here takes something you type and computes an answer for it. All of them run entirely in your browser — nothing you paste in is uploaded, logged or stored — and every result is a link you can copy and send to someone.

• Confusable-Word Checker

  Paste a sentence or a paragraph and every confusable word in it is flagged against this site's 375 researched pairs — with a verdict on the sentence you actually wrote, not just a definition of the pair.

• Plural & Possessive Builder

  Type any noun and get all four forms at once — singular, plural, singular possessive, plural possessive — including compound titles like "editor in chief" and Latin plurals like "addendum".

• Punctuation Reference & Checker

  Pick a punctuation mark and get its real spacing and placement rules with right and wrong examples side by side, then run your own sentence through a mechanical punctuation check.

Also on the site

• Which-Word Quiz

  A genuine multiple-choice quiz drawn from the site's confusable-word pairs, scored client-side, with the correct usage explained after each answer.

• Apostrophe Checker

  Paste a sentence and get flagged on common apostrophe mistakes (its/it's, plural vs. possessive, greengrocer's apostrophes) via client-side pattern rules — not a full grammar-checker API.
