Default Handwriting recognition

I have a Thinkpad X41 tablet, currently running Linux because xf86-input-wacom doesn’t (currently) run on OpenBSD. What are some useful programs for working with tablet input and/or handwriting recognition?

For taking notes in class or writing on PDFs, Xournal works pretty well. You can write on top of any PDF, and export the result as PDF, making it useful for signing forms (instead of the typical “download, print, fill out, scan, email” cycle). It doesn’t do any handwriting recognition, though.

Another program I’ve found useful for identifying Japanese characters is KanjiPad (OpenBSD/FreeBSD japanese/kanjipad, pkgsrc misc/kanjipad).

I’ve found some web apps that do handwriting recognition as well. I’d like to find native apps that replace them, to avoid being reliant on external servers, internet connection, and a bloated web browser.
  • shapecatcher: finds a Unicode character.
  • Ajax Hwr: finds a Japanese character. Like KanjiPad but recognizes kana too.
  • Web Write: converts written sentences to plain text.
  • Web Equation: converts handwriting to LaTeX or MathML.
  • Detexify: like Web Equation but only does single LaTeX characters. Source code available.
