Most spelling errors are not exotic — they are the same dozen confusions repeating themselves: "their/there/they're," "its/it's," "loose/lose," "affect/effect," "definitely/definately," and the silent typo where your finger hits the wrong key and the result is still a real English word so the underline never appears. Our online Spell Checker catches both kinds. It works against a comprehensive English dictionary (US and UK spellings) plus a frequency-weighted suggestion engine that ranks corrections by how likely each one is given the surrounding text, rather than dumping ten unsorted alternatives on you. Paste in an email, an essay, a blog post, a product description, a cover letter, or a social media caption, and every misspelled word is highlighted with a one-click fix suggestion. Proper nouns, technical terms, and your own brand names can be added to a session whitelist so they stop being flagged after the first time — the dictionary is custom-extensible per session without storing anything across visits. The checker handles contractions, hyphenated compounds, and possessives correctly (it knows "don't" is a real word and "dont" is not). What it does not do — by design — is rewrite your sentences for style or grammar; for those, use the Grammar Checker. The split exists because conflating spelling and grammar in one pass produces noisy, contradictory suggestions; checking one layer at a time is faster and gives cleaner output. The whole pipeline runs locally in JavaScript, which is why there is no character limit and no daily quota: nothing is sent over the network. Real-world workflows: proofing a job application before submitting, scrubbing client emails for embarrassing typos, double-checking blog drafts before publishing, and catching the subtle homophones AI grammar tools often miss.

Frequently Asked Questions

Spelling-only checkers (including this one) cannot catch homophone errors because both spellings are valid English words. Those are grammar errors disguised as spelling errors — they need contextual analysis. For homophone catching, run the text through the Grammar Checker after the spell check pass.
Yes — click "Add to dictionary" on any flagged word and it becomes whitelisted for the rest of your session. The whitelist lives only in memory, so closing the tab clears it. We deliberately do not persist a custom dictionary across visits, because storing a personal word list would mean storing identifying data.
Yes. Both "color" and "colour", both "organize" and "organise", both "center" and "centre" are accepted as valid. If you want strict adherence to one variant, the language toggle filters the dictionary to that side only — useful when you are writing for a specific market and need consistency.
Built-in checkers are excellent for in-context typing, but they often skip text inside form fields, web app editors, or Markdown source. This page is the right tool for proofing pasted text — anything you copy out of a chat client, a CMS draft, an email composer, or a code editor where the native spell-check is missing or unreliable.
