Inkwell recognizes your handwriting. Just write on a graphics tablet, and the
Jaguar (Macintosh operating system) turns it into typed text at the cursor in
any application. Inkwell just works with all your existing applications. No
upgrades, no application changes are necessary.

Inkwell lets you write wherever you want to on the screen, and the recognized
text just flows to the current insertion point, as if you’d typed it on a
keyboard....
