Greplin is a unique search engine that searches user-defined indexes for information that they have stored in a cloud. With their Chrome extension, users can connect their Greplin account to Gmail. This will allow them to use Greplin instead of Google Search when looking through their inbox, getting faster results.
The site was launched in September 2010. Since then it has raised over $4,5 million in funding.
Greplin is similar to a desktop computer search, except that it searches public and private data that has been stored in a cloud, or off of the actual computer.
Users choose which services to index from Facebook, Twitter, Google Voice, Gmail, Dropbox, LinkedIn, Google Docs, SalesForce, Google Calendar, Evernote, and Basecamp. Indexes are easily managed through the application and may be added or removed quickly.
Searches use auto-completing to make the search process much faster. Users may limit the scope of the search by choosing a specific service to search. It is also easy to see what sites have already been indexed from the clean interface.
Right now the application is in beta and is oversubscribed. The site will gladly accept email requests to be added to the registration queue.
Greplin will be free for most searches and may charge a fee for advanced search features.
Greplin will be a useful tool for anyone who has a need to regularly search for information that they have stored on other sites. It claims to search 1000x faster than a Gmail search and the auto-completing feature brings up results in seconds.
