Visit English Syntax Highlighter

English Syntax Highlighter is a web tool that applies natural language processing to English text to identify the part of speech of each word and color it accordingly. It is designed to handle ambiguous sentences, such as "The man we saw saw a saw," where words can serve different grammatical roles. Users paste text into an input area and press tab or click outside the text area to refresh the highlighting.

The tool highlights adverbs, nouns, adpositions, determiners, interjections, particles, punctuation, verbs, numbers, conjunctions, adjectives, and unknown words, with a legend for reference. An underline mode can be toggled instead of text colors, and colors can be toggled by clicking the legend. The tool runs in the browser with no account required, and the pages do not describe a free plan, trial, or paid editions.
