Downloading PlaintextPaste 0.2 for Mac from our website was free. The program is included in Productivity Tools. This free Mac app was originally produced by Robin Hamilton-Pennell.
From the developer:
PlaintextPaste is a simple SparkPlugin that adds a "Paste Plain Text" item to the Edit menu of all Cocoa applications. Normally the Paste menu item will preserve all colors, styles, fonts and formatting of so-called "rich text." However, sometimes, you don't want all this formatting, especially when copying text from the web. Thus, "Paste Plain Text."
