About the Spell Checker

A full dictionary spell checker needs a dictionary — hundreds of thousands of words, plus every inflection, name and technical term — and one that runs entirely in your browser would be a large download that still flagged half your vocabulary as wrong.

So this works the other way round, and does it well. It checks against a curated list of the spelling mistakes English speakers genuinely make — around a hundred and sixty of them, from "recieve" and "seperate" to "definately" and "occurence" — plus rule-based checks for doubled letters, transposed characters and repeated words. Every flag comes with a correction. It will not tell you that an unusual word is unknown, and it will not produce the false positives that make full checkers exhausting. British and American variants are handled as a preference rather than an error.

Key features of the Spell Checker

No false positives

It flags known mistakes, so it never marks your surname or a technical term as wrong.

British and American as a preference

Both are correct English, so the tool asks which variety rather than declaring one an error.

Corrections offered

Every flag comes with the right spelling, applicable individually or all at once.

Rule-based extras

Doubled letters, transposed characters and repeated words are caught by rule rather than by list.

Honest about coverage

The page says plainly what it will miss, and what to use instead for those cases.

Frequently asked questions

Because a browser-based dictionary large enough to be useful would be a substantial download, and would still flag names, jargon and technical terms as errors. Checking known mistakes gives high precision with no false positives.
