Lexical Computing is a research company working at the intersection of corpus and computational linguistics. Our linguistic databases (corpora) and tools for their searching, analysis and building are used by companies operating in the field of language technologies, artificial intelligence and natural language processing. They are also used by hundreds of universities from around the world.

The flagship product of Lexical Computing is Sketch Engine, a leading corpus management and corpus query tool used by linguists, lexicographers, translators and publishers worldwide. Its unique feature – the Word Sketch – and its derived functionalities together with the scalability, multilingual support and ability to handle the largest corpora available make Sketch Engine a unique linguistic tool. The access to Sketch Engine is provided free of charge for students of Masaryk University.
