Application possibilities

Selected items

Privacy: analysis performed only on the local computer (based on own local databases) - the program does not send files to the server

Spanish and Romanian (

Searching for documents on the disk

based on the terms entered by the user, taking into account their similarity, and not only identity to the words that make up the document

Searching for files (

Technical specifications
