Google has announced a new experiment in Google Labs called Google Scribe which provides you with autocomplete suggestions as you type.
Google Scribe in a nutshell is a text completion service which uses Google Docs to provide related word or phrase completion suggestions as you type. In addition to that Google Scribe’s suggestions also indicate correct or popular phrases to use.
Google Scribe provides autocomplete suggestions in several languages and also provides users with several keyboard and mouse shortcuts.
The interesting thing about Google Scribe is that it allows for easy integration with any webpage by using the Google Scribe Bookmarklet. So this would also allow you to use it with any website which provides you with a textbox or textarea to enter content. However, this feature does not work with Google Docs and it would be interesting if Google integrates it with it.
