LetMeType helps you enter text, but regardless of the program you use. Running in the background, it analyses what you type. After some time it has collected enough information to guess a word after you have typed the first two or three letters. A list of the most probable words is displayed, and you can select one with a single keystroke or just continue typing.
LetMeType works independently of the program you enter the text into - be it a word processor, the editor of a development environment or a dialog box field. Its behaviour is highly customizable. You can set the maximum number of suggestions and their frequency. For skilled keyboard artists it is possible to limit the suggestions to long words with a high probability. Unobtrusiveness is also important: the window containing the suggestions is displayed and removed quickly, and you can always ignore it and continue typing.
Two other important aspects are privacy and security. LetMeType only stores single words, but no continous texts. There also is a secure way to prevent passwords entered into other programs from being monitored and stored by LetMeType.
