Terminology consistency checker
Finds places where a document says the same thing two different ways — spelling variants, US/UK dialect mixing, and (if you paste your own list) your house style's preferred terms.
Your text never leaves your browser.
Paste a document above to check its terminology for spelling drift and dialect mixing.

Custom term list (optional)
One rule per line: preferred = variant one, variant two, or paste two columns from a spreadsheet (preferred,variant). Any variant on the list is flagged even if the preferred form never appears. Saved in this browser only — it never leaves your device.

What counts as terminology drift
A word repeated often isn't a problem. The same word spelled two different ways in the same document is — it's the kind of inconsistency a reader notices even when every individual sentence reads fine on its own. This tool only ever flags a term when two or more competing forms actually occur in your document. A document that says "e-mail" twenty times, consistently, is not flagged, even though this tool would prefer "email" — internal consistency always beats any house preference.
Spelling variants
UI and technical nouns that get written more than one way: dropdown / drop-down /drop down, login / log-in, website / web site. Verb/noun pairs like "set up" (verb) and "setup" (noun) are deliberately excluded from this class — they're genuinely different words, not a spelling choice, so flagging them would be wrong more often than it would be right.
US/UK dialect mixing
organize / organise, color / colour, center / centre, and hundreds of related pairs. This tool determines your document's own dominant dialect by majority, then flags whichever spellings go against that majority — not against some external "correct" answer. A document that's consistently UK English is never flagged for being UK English.
Your own term list
Paste a house glossary — preferred term on the left, forbidden variants on the right — and this tool enforces it the same way, entirely in your browser. Unlike the built-in classes, a custom rule fires the moment a forbidden variant appears, whether or not the preferred term is also present, since a house style list is a standing rule, not just a drift detector.
