AntWordProfiler is Laurence Anthony's free desktop vocabulary profiler, distributed at https://www.laurenceanthony.net/software/antwordprofiler/. It analyses any text or batch of texts against one or more frequency lists, reports coverage at each level, flags off-list items, and produces colour-coded display output. Within the AntSuite of corpus tools (AntConc, AntCorGen, AntFileConverter), it occupies the slot that RANGE held in the desktop era and is the standard alternative to web-based Lextutor for researchers who need local processing or custom lists.
The tool accepts plain-text input and a stack of user-loaded frequency lists. It tokenises, matches each token against the lists in order, and returns three views: per-list coverage statistics (tokens, types, families, percentage), a profiled version of the text with each token colour-coded by its source list, and a level breakdown that stacks list contributions cumulatively. Output exports as CSV or annotated text for downstream analysis.
The native list format is line-based, with one headword per line followed by family members, matching the convention used by the Nation BNC/COCA lists. Users can load any list set that follows the format: BNC/COCA 1K–25K, GSL+AWL, the New General Service List, custom in-house lists for specialised domains, or research-specific list combinations. List swapping is a few clicks rather than a recompile.
The tool runs on Windows (installer and portable builds), macOS (Apple Silicon and Intel), and Linux (Flatpak). [unverified] Version 2.x is the current line as of 2026; the 1.x series remains available for legacy use. Anthony develops and maintains the suite from Waseda University in Tokyo and ships incremental updates regularly.
Against RANGE, AntWordProfiler offers a modern GUI, native execution on current operating systems, larger input handling, and support for any list format the user supplies, against RANGE's ageing Windows-only build and fixed list slots. Against Lextutor, it offers local processing (no copyrighted text sent to a server), batch profiling for whole corpora rather than single pasted texts, and granular export, against Lextutor's larger built-in list catalogue and integrated concordancer. Researchers who profile dozens or hundreds of files routinely move from Lextutor to AntWordProfiler at that point.
