Tippr is a Chrome extension developed by Kor Labs that aims to revolutionize Bitcoin tipping. It allows users to tip anyone, regardless of whether they have a Bitcoin wallet or a social account. Similar to Changetip, Tippr sends recipients notifications when they receive tips.

To utilize Tippr, users can simply visit a website and click on the Tippr Chrome extension. The extension then generates a Bitcoin address for the website owner and sends them instructions via email, obtained by querying a WHOIS database. If the website owner does not claim the tip within a week, it is returned to the sender.
