Apple Inkwell for Mac

From Apple:

Inkwell recognizes your handwriting. Just write on a graphics tablet, and Jaguar 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 youd typed it on a keyboard. So when youre working with a graphics tablet, theres no need to put down the pen and return to the keyboard just to enter a title, caption or filename. You can also write command-key shortcuts with the pen  its easy to open and close windows, and otherwise control your applications, without lifting your pen from the tablet.

Built on Apples Recognition Engine Inkwells handwriting recognition is the best in the industry. Beyond just words and numbers, you can also use Inkwell to write commands. Inkwell provides a set of easy to learn and remember gestures that are convenient for carrying out common functions, such as cut, copy, paste and select-all, with a single stroke of the pen.

While in handwriting mode, you can still drag windows and use scrollbars and other controls immediately. The pen knows to behave like a mouse instantly in these special places. For other places, you can just press and hold the pen still briefly to use it like a mouse, anywhere.

You use Ink on a floating window to automatically insert text at the cursor. This window can mimic standard modifier keys, so you can write command-key shortcuts, bring up contextual menus, and so on, without having to return to the keyboard. You can shrink the window to a single button, which saves screen real estate while letting you toggle the pen between the pure mousing behavior used for drawing and painting and its handwriting behavior.

Conversely, you can expand the floating window to InkPad, a handy utility application. The InkPad app offers additional features for writing and editing, such as alternate word lists and targeted gestures. InkPad also lets you draw quick sketches and paste them in most other applications. So you can draw a quick map to the party, or communicate that new design youve got in mind, and send it out with your email, effortlessly.

Preferences allow you to add uncommon words to your own personal word list, for maximum recognition accuracy. And if your writing style is a little bit differentmaybe you write your words closer together or letters farther apart than the averageyou can fine-tune the recognition to suit your style.
