NoSketch Engine

Welcome to NoSketch Engine, an open-source project combining Manatee and Bonito into a powerful and free corpus management system. NoSketch Engine is a limited version of the software empowering the famous Sketch Engine service, a commercial variant offering word sketches, thesaurus, keyword computation, user-friendly corpus creation and many other excellent features.


Manatee is a corpus management tool including corpus building and indexing, fast querying and providing basic statistical measures. It utilitates a fast indexing library called Finlib.


Bonito is a graphical user interface to corpora maintained by Manatee. It is a web interface written in Python which can be running under any webserver supporting the CGI.
