Licenses & Data Sources
Our anagram solver runs entirely in your browser and uses only free, redistributable word lists. This page lists every source and its license.
ESDB (English Speller Database, formerly SCOWLv2)
Word lists generated from the ESDB custom list creator at app.aspell.net/create, US spelling, diacritics stripped. Game-level list from ESDB size 80; the default display list additionally uses ESDB size 70. Both are generated from the same database and covered by the same license below.
Copyright 2000-2026 by Kevin Atkinson Permission to use, copy, modify, distribute, and sell any part of the English Speller Database (ESDB, previously known as SCOWLv2), or word lists created from it, is hereby granted without fee, provided that the above copyright notice appears in all copies and that both the above copyright notice and this notice appear in supporting documentation. Kevin Atkinson makes no representations about the suitability of this database for any purpose. It is provided "as is" without express or implied warranty. ESDB is derived from many sources, most of which are in the Public Domain. Data from the Corpus of Contemporary American English (COCA) was also used. All data from COCA comes from 3-gram data that is not freely available; however, the usage is within the rights given by the NDA that was signed when purchasing the data. More information on COCA is available at https://www.english-corpora.org/coca/. The primary source of words for ESDB comes from 12dicts and ENABLE2K. Both are in the Public Domain, but Alan Beale <[email protected]> deserves special credit as he is the author of 12dicts and a major contributor to ENABLE2K. In addition, he gave me an incredible amount of feedback and created a number of special lists in order to help improve the overall quality of ESDB.
Generated lists larger than size 80 include the UK Advanced Cryptics Dictionary (UKACD) and carry additional terms. We use size 80, which does not include UKACD.

ENABLE
The Enhanced North American Benchmark Lexicon was formally released into the public domain. Its clean version is redistributed here as part of Re-Enable (above).
Common-word marker
words-popular.txt is not another dictionary and adds no searchable words. It marks which results are familiar, so those can be shown first. The marker is the overlap of our game list with popular.txt, itself the overlap of public-domain ENABLE and Wiktionary's English frequency lists (compiled from about 29 million words in TV and movie scripts). The file is alphabetical. It is a yes-or-no marker, not a frequency ranking.
What We Do Not Use
We do not use any copyrighted tournament word lists, including the Official Scrabble Players Dictionary (OSPD), SOWPODS, or the TWL/NWL lists. Words in those lists that appear in our results come from ESDB or Re-Enable independently.
