GOCR claims it can handle single-column sans-serif fonts of 20–60 pixels in height. It reports trouble with serif fonts, overlapping characters, handwritten text, heterogeneous fonts, noisy images, large angles of skew, and text in anything other than a Latin alphabet.

The application was originally named GOCR which stands for GNU Optical Character Recognition. When it came time to register the project on SourceForge the name GOCR was already taken so the project was registered as JOCR (Jörg's Optical Character Recognition).
As a result of this situation the project and application are known as both GOCR and JOCR. Schulenburg admits that this is problematic.
