Free Spell Checker — Instant Online, No Signup

Paste your copy to identify words that do not match the internal dictionary and review ranked spelling alternatives.

1. Step 1: Paste text to checkAdd articles, product descriptions, or any plain text you want to scan for spelling issues.
2. Step 2: Run the spell scanThe checker tokenizes words and compares them against a built-in dictionary on the server.
3. Step 3: Review suggestionsFor each flagged word, review up to five suggestions ranked by edit distance and apply corrections in your editor.
4. Step 4: Paste your textAdd your text into the main field. Long drafts are fine for typical article lengths.

The spell checker is rule-based and dictionary-driven—not powered by generative AI. It extracts word tokens from your text, normalizes casing for lookup, and flags terms absent from the internal word list. For misspellings, it generates suggestions by computing Levenshtein edit distance against dictionary entries, returning up to five close matches per flagged word.
