Catch spelling mistakes, typos and commonly confused words instantly. Powered by the LanguageTool public API which runs sophisticated pattern matching beyond simple dictionary checks.
A spell checker finds incorrect spellings by comparing your text against a dictionary and applying contextual rules for confusable words (their/there/they're, your/you're, etc.). LanguageTool's open-source engine is the industry standard for free spell checking and supports 30+ languages.
Paste your text and click Check. The tool sends your text to api.languagetool.org over HTTPS, parses the matches, and shows each issue with the exact location, the rule that flagged it, and up to 3 suggested replacements. Issues are highlighted directly in your text.
Run it on every email before sending, every article before publishing, every form submission with significant text, and every social media post that represents your brand. Pair with grammar and proofreading checks for full coverage.
For large texts, the free public API caps at 20 checks per minute per IP. For higher volume use the paid LanguageTool premium tier or run a self-hosted instance. The API supports en-US, en-GB, en-IN and many other locales.
Yes — LanguageTool supports en-IN with India-specific spellings and conventions.
Some — confused-word rules cover their/there, your/you're, its/it's, and similar patterns.
No — LanguageTool's public API doesn't store text by default. Their privacy policy confirms ephemeral processing.
