Can you help remember the name of a project shared on Hacker News?

Sometime ago I saw a post on Hacker News about a project and have since forgotten the name of, but I am now realizing it would be very helpful to us.

So what I do know: - It sent searches to multiple sites using your local session cookies - It was open source - I think it started with an E (but am less sure about that as time goes on) - The creator linked a Youtube video presentation of it.
