What Voyant Tools is

Voyant Tools is an open-source environment for reading and analyzing digital texts, available as a hosted web app and a local server. To build a corpus, users can paste text, enter URLs, open an existing corpus, or upload files. It can extract text from HTML, Word, Excel, ODT, Pages, PDF, plain text, RTF, and XML. Its starting workspace brings together Cirrus, Reader, Trends, Summary, and Contexts, with more tools for examining terms, collocates, and phrases. Users can bookmark and share corpus URLs; a corpus generally remains available when accessed at least monthly. Voyant can also be embedded in other sites with an iframe. For offline analysis, VoyantServer runs locally without an internet connection and does not cache work on Voyant’s server. It requires Java 11, with setup instructions for Mac, Windows, and Linux. The hosted service logs tool use, parameters, and IP addresses, uses Google Analytics, and stores submitted text for persistent access. Voyant handles Unicode text in almost any language, but has limited language-specific semantic analysis. The free service is licensed under GPL3.
