A quick-and-dirty spell check right in your browser
Here’s what this does: it compares every word in your text against a built-in dictionary of about 500 common English words. Anything it doesn’t recognize gets flagged, and it suggests corrections using Levenshtein distance: basically measuring how many character edits separate the misspelled word from the closest match.
It’s not Grammarly. It’s not trying to be. But for catching obvious typos before you hit send? It gets the job done. And since the dictionary is baked right into the page, it works without any API calls. Your text doesn’t go anywhere.
What it does
- Checks each word against a curated dictionary of common English words
- Highlights potential misspellings
- Suggests corrections ranked by edit distance (fewer edits = better match)
- No API calls, the dictionary is local, so this works offline too
- Completely private, nothing leaves your browser
Using it
Paste your text. Click “Check Spelling.” Flagged words get highlighted with suggested corrections underneath.
Try this: “The quik brown fox jumps over the layz dog.” It’ll flag “quik” and “layz” and suggest “quick” and “lazy.” Straightforward.
When it’s helpful
Pre-send proofreading: before firing off an email or social media post, run it through here. Catches the embarrassing typos.
Early draft scanning: you’ve blasted out a rough draft and want to know where the obvious spelling errors are before getting into real editing.
Non-native English speakers: quick verification that you’ve spelled an unfamiliar word correctly. Faster than googling it.
Data cleanup: if you’ve got a spreadsheet with text fields full of misspelled entries, paste them in and see what gets flagged.
Learning how words relate: the edit distance feature is actually educational. Seeing that “recieve” is just one character swap away from “receive” reinforces the correct spelling.
For fixing repeated misspellings across a long document, use the Find and Replace tool after you’ve identified the errors here.
Important caveat
The dictionary is intentionally small, around 500 common words. It’ll flag proper nouns, technical terms, brand names, and plenty of perfectly valid words that just aren’t in its vocabulary. Think of this as a first-pass typo catcher, not a comprehensive spell checker. For the full experience, combine this with your browser’s built-in spell checking.
FAQ
How big is the dictionary?
About 500 common English words. Kept small on purpose so it runs efficiently in the browser. The tradeoff is that uncommon-but-valid words get flagged.
How do the suggestions work?
They’re based on Levenshtein distance: the minimum number of single-character insertions, deletions, or substitutions needed to turn one word into another. The closest matches in the dictionary come up first.
Does it catch grammar errors?
No. This is spelling only, it checks if individual words exist in the dictionary. Sentence structure, word usage, and grammar aren’t analyzed.
Is it a replacement for a real spell checker?
Nope. For comprehensive spell checking with a full dictionary, context-aware suggestions, and grammar checking, use your browser’s built-in tools or a dedicated writing assistant. This is for quick catches.
Is my text private?
Completely. Local dictionary, local processing. No server, no transmission.
