Downloading Gochiusearch 1.2 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Lifestyle Tools, more precisely Entertainment. This free Mac application is a product of Tsubasa HIRANO. We recommend checking the downloaded files with any free antivirus.
From the developer:
Gochiusearch is a fast scene search application for Anime Series 'Gochuumon wa Usagi Desuka?'. The tool supports dragging and dropping the desired image file to search for a scene. In addition, the tool lets you jump to the Niconico website to watch the movie related to the identified scene.
You may want to check out more software for Mac, such as R2D2 Translator, DimSum or PrankExport, which might be similar to Gochiusearch.
