#1 comic software worldwide
As of April 2018, Smith Micro Software no longer sold or provided support for Clip Studio Paint or Manga Studio. It began distributing Manga Studio after acquiring the graphics division of E-Frontier, Inc in November, 2007.
CELSYS provides technical support for copies of CLIP STUDIO PAINT / Manga Studio purchased from Smith Micro. Although CELSYS is a Japanese corporation, their capable English support staff will be more than happy to provide user support.
