When you're like me, frantically spouting words to keep up with your thoughts, doing all sorts of stuff hence having numerous programs open and running... then you might be in need of some kind of dictionary/spelling checker. But most of those programs claim too much space, resources and become more of a annoyance, rather than being useful.

tinySpell is just the right fit. This humble piece of software doesn't get in my way and I can enable/disable it with a single touch. But best of all, it's free!
