Search 200+ archives at once
Paste anything, a URL, DOI, ISBN, social handle, file hash, or just a title. We detect what it is and route to the right archives.
How it works
Three steps, no account, and no copies stored on our side.
-
Paste anything
A URL, a bare domain, a DOI, an ISBN, a YouTube link, an image address, a file hash, a social handle, or just a title you half-remember.
-
Echo works out what it is
Detection routes your input only to the archives that can actually answer it, instead of firing it blindly at all of them. A DOI goes to the paper indexes; a dead domain goes to the web archives.
-
You open the archives yourself
Each result is a working deep link into that archive, grouped by what it holds. Echo stores no copies and hides nothing behind an account.
What you can look up
Paste the thing itself, and Echo picks the archives that hold that kind of material.
