I am constantly copying text into an app such as Word, just to spell check it. I decided to build a simple spell check app that would sit on the tray and spell check whatever text was in the clipboard. I did a quick search on Google, and found that someone had already built such an app.
TraySpell uses the NetSpell C# library to provide a simple tray tool that spell checks whatever is in the clipboard. When I first tested it, is missed some pretty obvious words, but once I updated the dictionary to include the words from the Open Office English dictionary, it seems to work pretty well (although it still doesn’t understand some obvious words such as “tray” and “tool”).
