Mobysaurus Thesaurus is a English thesaurus tool that helps you write and speak better by leading you to the right word for every purpose or occasion. The app contains 2.5 million synonyms and growing, instant results, cross-referencing, fast full-text search, and requires no network connection.

The program is powered by the most recent version of Moby Thesaurus (compiled by Grady Ward), which is the large and most comprehensive English thesaurus data source available to date in the public domain. Having over 30,000 headwords (main entries), and 2,500,000 synonyms and advanced search functions at your call, it's unsurprisingly that simple for you to be wise at words.

It runs locally. There's no need to connect to the Internet, open up your browser, type in URLs, wait for pages to load, click on/view advertisements, and sometimes expose your system to spyware/adware threats.
