KallOut brings “selection-based search” to any Web page, e-mail message, presentation, document, spreadsheet, or PDFfile. Unlike other search methods that are trapped inside the browser, KallOut serves up content from the most popular sites on the Web inside floating information palettes (which we call KallOuts). Using only your mouse, you can now avoid the disruption of launching a browser and let KallOut bring you the best the Web has to offer. KallOut is designed to seamlessly integrate into the everyday tools you already use. There is no learning curve. Instead of copying text and then pasting it into a browser whenever you want more information, you just select text and KallOut does the rest. KallOut now supports the ability to customize your list with any search site. Version 0.9.5 Beta includes various upgrades and enhancements.
