Stella

About

You are certain a file is on your computer, but Spotlight cannot locate it. Stella can. Simply describe it, such as "my final exam study guide" or "last week's meeting product specification," and Stella will find it. You can then drag the file directly into Gmail, open it, or launch any application from the same toolbar. It is one shortcut for your entire Mac. The service is free, private, and requires no account. Poorly named files are no problem.
