Precipitate lets you search for and launch your data stored in Google services from Spotlight or Google Desktop for Mac. It currently supports the following services:

• Google Bookmarks
• Google Docs
• Picasa Web Albums

Precipitate works by creating files on your machine that are imported by Spotlight, then periodically checking in with the server and updating the local files to reflect any changes. Note that changes may take up to an hour to be visible in local searches.

Installation and Setup - Open the Precipitate preference pane, and install it either for yourself or for all users. Enter your Google account information into the preference pane, check the box for each service you want to make searchable, then press "Refresh Now" to start the initial import (note that this may take some time, depending on how much data you have). Then just start searching!
