PenOffice is a combination of a powerful handwriting recognition engine, and applications which allow you to extend the core PenOffice functions. This combination includes:

• Natural handwriting recognition: handwriting recognition engine component of PenOffice recognizes print, cursive, and mixed script as well as arbitrary symbols and control 'gestures'.
• Multilingual Support: PenOffice now supports nine languages and includes eleven dictionaries: Danish, Dutch, English (US and UK), French, German, Italian, Norwegian, Portuguese (EU and BR), Spanish and Swedish .
• Immediate usability: Unlike many handwriting recognition programs, PenOffice is ready to run right out of the box with no training required. You can, however, customize PenOffice to your personal handwriting style, thereby increasing PenOffice's already superb accuracy and speed.
• Built-in dictionary: PenOffice recognizes words from its integrated dictionaries. This includes a main dictionary containing approximately 100,000 words and a custom user dictionary. PenOffice also recognizes non-vocabulary words like personal names, geographical names, and arbitrary handwritten symbol strings.
• Inline Gestures: PenOffice allows you to embed control gestures in your writing. Simply write, inserting the gesture as you do, and keep writing. PenOffice recognizes the text and formats it based on the gesture(s) embedded within the text.
• Screen Draw mode: This feature allows you to use your screen as a virtual ScratchPad. You may save and e-mail drawings. You can also write while in drawing mode and have PenOffice convert your handwriting into typed text at a later time (deferred recognition).
• JPEG and PNG support: PenOffice lets you send your handwritten Notes and ScreenDraw drawings in PNG, JPEG and BMP formats, thus allowing your work to be viewed on multiple platforms.
• Microsoft Office and OpenOffice.org Markup mode: Using PenOffice, you can mark up and forward your edits to others using Microsoft Office Word, Excel and Power Point documents as well as the Sun Microsystems' OpenOffice.org Writer, Calc, Impress, and Draw applications. PenOffice supports Microsoft Office XP or later and OpenOffice.org 3.0 or later.
• PenCommander: PenCommander is a new feature in PenOffice, which allows you to launch pre-recorded, user-defined commands (PenCommands). To execute a PenCommand simply write the "Word Command" and draw a circle around it. PenCommander features are available only while PenOffice is in Recognition mode.
• Customizable on-screen keyboard: You can choose any characters, punctuation signs, or navigation buttons to appear on a 24-key customizable keyboard. Redesigned full on-screen keyboard now features 13 pre-defined layouts. You can also change the transparency of the keyboard.
• Spell checker: This feature works with practically any Windows application.
• ScratchPad: ScratchPad provides you with the electronic equivalent of 'sticky notes'. 
• RiteCalc handwriting calculator: Simply write an equation, and let RiteCalc do the math for you.
• Extensive correction interface: By pointing out PenOffice's mistakes, you can improve its performance.
• Expandable Architecture: Look for future applications that will take advantage of PenOffice's powerful capabilities to further enhance your computing experience.
