ComiPo is a software for manga creation. It has similar capabilities to Manga Studio but with the addition of pre-made backgrounds and 3D character models you can use right out of the box. You also have the option of buying expansion packs to increase the amount of props, scenes, and clothes for the 3D models or if you’re in a budget, there are freebies available. Check out this previous post or hit up the official website for more information.
ComiPo is available for $49.99USD at Crunchyroll and ComiPo.info but it’s for sale at Comradz for $39.99 for now so if you’re interested, head over there now. It only works on Windows OS from XP up to 7. No Windows 8 compatibility notice so far but I believe they’ll eventually provide one.
