I Write Like is a free, web-based text analysis tool that compares a user-provided text to the prose of well-known writers using statistics, word choice and writing style analysis. It then reports on which writer the text most resembles. The tool requires at least two paragraphs of text for best results. At this time, the results are limited to the name of a writer, without offering more detailed insight into the analysis; the tool appears to be offered primarily to promote the Memoires journaling software.

STASEL (Stylistic Treatment at the Sentence Level) is a historically important program designed to analyze text. It was intended for language and style instruction, but had research-based applications.

AUTOSTYL was a set of linked programs for stylistic analysis developed by Louis T. Milic in the 1980s. Its functions included frequency distributions for letters in words, syllable countering, affix analysis, indexing, and word classification.
