tinySpell – freeware (totally free – no adware/spyware/nagware/etc.)
Occasionally you need to check spelling in an application that does not include a spelling checker and you don’t want to launch your word processor just for that. This is when tinySpell becomes handy. It is a small utility that allows you to easily and quickly check and correct the spelling in any Windows application.
tinySpell can watch your typing on the fly and alert you whenever it detects a misspelled word.

• It can also check the spelling of text that you copy to the clipboard.
• tinySpell installs itself in the system tray for easy access.

Two variants are available:
• tinySpell:  a freeware (totally free – no adware/spyware/nagware/etc.)
• tinySpell+: with more features (buy now – pick your price)

This download is for the freeware version.

Checking your spelling is simple:
Option 1:
While you are typing, tinySpell watches the text you enter and whenever it detects a misspelled word it beeps and shows a spelling tip, and the tinySpell icon in the system tray turns from white to yellow .
Option 2:
When you copy text to the clipboard tinySpell checks its spelling immediately. If it finds at least one misspelled word in the text it beeps and turns its icon to yellow. If the icon is white it means that no misspelled words were found in the clipboard text.
Correcting a misspelled word is also simple: When a misspelled word is detected, click the tinySpell icon or press the hot-key to pop up a list of suggested replacement words. If the misspelled word is detected during on-the-fly checking or after a word is copied to the clipboard you can select a correction from the list. The selected word is inserted into your document, or is copied to the clipboard (so you can paste it in your document), or both (depending on your settings).
