Why Choose Our Spell Checker?

Our tool works entirely offline: the dictionary of 500+ common words is built into the page, and all comparisons happen locally using the Levenshtein distance algorithm. You get up to 5 relevant suggestions for each misspelled word, and you can replace individual occurrences or all of them at once. The ignore case and ignore numbers options give you fine‑grained control, and the visual error list makes it easy to review and fix mistakes one by one. Whether you’re proofreading a blog post, an email, or a student paper, this tool delivers fast, private, and accurate results.

Frequently Asked Questions
Does the spell checker work offline?
Yes, after the page loads once, the entire dictionary and algorithm are stored locally in your browser. You can use it without an internet connection.
How many words are in the dictionary?
The built‑in dictionary contains over 500 of the most common English words. You can easily expand it by editing the JavaScript array in the tool’s code.
What is the Levenshtein distance?
It’s an algorithm that measures how many single‑character edits (insertions, deletions, substitutions) are needed to change one word into another. This allows the tool to find the closest matching words in the dictionary.
Can I replace all occurrences of a misspelled word at once?
Yes. Click the “Replace All” button next to any error to replace every instance of that misspelled word with the top suggestion.
Is my text sent to a server?
