Spell Checker
Check spelling
Cross-check words against a common-word list (~500 words). Flags unknown words.
How to use Spell Checker
- Paste your text.
- Words not found in a common-word list (~500 words) are flagged as potentially misspelled.
- Review flagged words — this catches obvious typos, not nuanced grammar or context errors.
Limitations
- Checks against a common-word list, not a full dictionary — proper nouns, technical jargon, and less common (but correctly spelled) words may get flagged even though they're fine.
