Greplin, the personalized search tool that lets you add data from your personal sources, has a new feature.

Now, Greplin indexes Google chats. The company said in a blog post:

Now you can search for your chats the same way you search for a Gmail Message. You’ll see results mixed in with the “Messages” results.

This won’t happen automatically. To enable this feature you must make sure “Show in IMAP” is enabled for Chats in your Gmail settings.

To add Google chats, just login to Gmail, click the gear icon, click mail settings, select labels, and next to chats, click show in IMAP.

Greplin says your chats should start showing up in Greplin searches within 24 hours.
