LexiFinder
AI-powered semantic indexing: automating the creation of book indexes
...LexiFinder works in two ways: as a command-line tool for scripting, automation, and batch processing, and as a graphical application for a guided, point-and-click experience. Both interfaces share the same underlying engine and support the same features.
Supported input formats are PDF, DOCX, and ODT. The index can be exported as plain text, JSON, CSV, or HTML.
