StretchLink expands "short" urls (bit.ly, t.co, tinyurl, and more) in text that you copy on your Mac. It can turn them into full urls, as well as clean out extra analytics and referral junk.
StretchLink sits in your Mac's menu bar, ready to work at any time.
StretchLink can (optionally) watch your clipboard and expand links automatically. When you copy text containing short urls, it expands them in place, instantly. By the time you paste, the full urls are in place.
