Quipquip and Rumkin offer online cryptoquip solvers. Quipquip can solve both crytpoquips in which word boundaries are preserved and not preserved. Rumkin can solve crytpoquips with only words found in its dictionary and not ones that include proper names or misspelled words.
The Rumkin solver sends the cryptograms entered to its server, so sensitive messages should not be entered. If there are many possible solutions, Rumkin only displays a subset. Quipquip shows only the first 100 solutions and divides those out into pages of 10. Quipquip also allows users to enter any known letter mappings in the clues box and include a carat in front of any words that may not be in the dictionary.
