1. A method of extracting content from a note using a computer system having one or more processors and memories, comprising: capturing, by a sensor, image data comprising a visual representation of a note, wherein the note comprises a physical note having one or more segments, each of the segments having at least one mark having a known characteristic; identifying, by the one or more processors, marks within the image data; based on the known characteristics of identified marks, determining, by the one or more processors, a general boundary of the physical note; based on the known characteristics of identified marks and the determined boundary of the physical note, determining, by the one or more processors, general boundaries within the image data for the one or more segments of the physical note; extracting, by the one or more processors and from the image data, content comprising a set of content pieces using the general boundaries, each of the content pieces corresponding to a different one of the one or more segments of the note; creating, by the one or more processors, a digital note representative of the physical note, the digital note having data indicating each of the segments for the physical note; and associating, by the one or more processors, the respective content pieces extracted from the image data with the corresponding segments of the digital note.
