MySpell was the former spell checker included with OOo Writer of the free OpenOffice.org office suite.
Since version 2.0.2 OpenOffice.org has replaced MySpell with Hunspell. MySpell was started by Kevin Hendricks to integrate various open source spelling checkers into the OpenOffice.org build. With a little prodding from Kevin Atkinson, the author of Pspell and Aspell, a new spelling checker (MySpell) was written in C++ that supported affix compression, based on Ispell.
