Contact
Questions, corrections and bug reports are all welcome at the same address.
There is no contact form here on purpose. A form needs a server to receive it, and this site deliberately runs without one — everything happens in your browser.
Reporting a missing or wrong word
Include the word and which dictionary you checked it against. Both lists are fixed, published sources rather than something we curate, so a genuinely missing word usually means the word is absent from ENABLE and SCOWL rather than that we dropped it — but it is worth knowing either way, and the dictionary check will show you what each list says.
Reporting a bug
The useful details are the letters you entered, what you expected, what you got, and which browser you were using. If a page was slow or a solve seemed stuck, saying roughly how long it took helps more than it might sound.
Anything else
For questions about what the site collects, the privacy page covers it. For how the solver works and which lists it uses, see about.
