Welcome to Weather-Above
Spell catcher plus is one of my favourite tools, this programme checks and watches what you type when an error is detected a window will display with a list of words to choose from, when you highlight a word in the window it automatically is read out to you. The programme as a full featured  thesaurus and a dictionary which allows you to look up the words you are interested in, there are features which allow you to use shorthand, for example: instead of having to type your address you can touch the 'hot key' and this automatically be displayed in your application.
