As a free URL redirection service Tweak has following unique features:
- Preview
It's easy to find out where any TweaKed domain will take you without visiting the actual page. This is useful to check that the link will redirect to a destination you trust. Simply add a slash hyphen (/-) to the end of the domain, and instead of being redirected to the original long URL, you will be shown a preview page telling you where the link goes. - Additional keywords
Anything in front of the Tweaked domain name is ignored. So if you'd like additional keywords or "hints" to a URL, you can take advantage of this to manually add them. - Tweet
While creating the cloaked domain you can directly tweet to inform the whole world about your new domain.
