Free Online Spell Checker — Fix Spelling & Grammar Instantly

Spelling errors in professional writing — emails, reports, blog posts, resumes — undermine credibility instantly. Studies show readers form negative impressions within seconds of encountering typos, and search engines penalise content with poor spelling as a quality signal. Our spell checker catches errors in real time so you can fix them before they matter.

Paste any text, and the checker highlights misspelt words, suggests corrections, and flags common grammar issues including punctuation errors, repeated words, and commonly confused word pairs. Supports both British and American English variants.

Spell Checker vs Grammar Checker — What's the Difference?

A spell checker compares each word against a dictionary and flags words that don't match any known entry. It catches typos, incorrect spellings, and made-up words but doesn't understand sentence meaning.

A grammar checker analyses sentence structure, subject-verb agreement, punctuation, and word usage in context. It catches "I goes to school" (verb agreement error) and "its a cat" (missing apostrophe), which a spell checker would miss since both "its" and "a" are valid words.

This tool combines both: dictionary-based spelling detection plus contextual grammar rules to catch errors that neither approach alone would find.

Best Use Cases

• Students and academics: Proofread essays, research papers, and dissertations before submission. Spelling errors in academic work reduce grades even when the content is correct.
• Professionals: Check emails, reports, proposals, and client-facing documents. A typo in a client email or pitch deck undermines professional credibility.
• Content writers and bloggers: Catch typos in articles before publishing. Search engines use spelling quality as a content quality signal.
• Non-native English speakers: Identify patterns in common errors to improve writing over time. The spell checker acts as a learning tool, not just a fixer.
• Developers: Check documentation, README files, code comments, and user-facing strings. Technical writing with spelling errors reduces perceived code quality.
• Job seekers: A single spelling error on a CV or cover letter can eliminate a candidate. Proofread with this tool before every application.

Tips for Getting the Best Results

• Paste complete paragraphs rather than single sentences — context helps distinguish intended word choices
• Check technical jargon, proper nouns, and brand names separately — these may be flagged as misspellings
• Run the spell checker before sending, not after — re-reading after correction often introduces new typos
• For formal documents, use spell check first, then read the text aloud to catch awkward phrasing the tool won't flag
• Set the correct language variant (British/American) to avoid incorrect corrections
