Web-based Lexical complexity analyzer - Single Mode
The Single Mode of the web-based Lexical Complexity Analyzer takes an English text as input and computes 25 indices of lexical complexity of the text. You may choose to see the results of any or all of the 25 indices, and the system will create a graphical representation to visualize the results. Additionally, you may enter another text in order to compare their lexical complexity. Please note that each text should have a minimum of 50 words and a maximum of 10,000 words. If you have multiple files to be analyzed, please use the Batch Mode. By accessing and using the Lexical Complexity Analyzer, you are acknowledging that you agree to be legally bound and to abide by the LCA Terms of Service.
