Write is a word processor for handwriting, designed primarily for tablets with an active stylus. Write has the functionality of a vector drawing application, plus a set of tools which ease the editing of handwritten text. This is made possible by grouping pen strokes into lines, much like typed text in a word processor. Handwritten text can be reflowed when words are deleted or space is added for new words. Bookmarks are labeled with handwriting. The native HTML+SVG document format can be viewed in any modern web browser. »
