Cryptocat is developed by privacy advocates, for privacy advocates. Big Data providers continue to amass gigantic amounts of personal information without providing any guarantee of privacy, while encryption remains largely inaccessible. This means that a lot of what you do online is not within your control, but rather susceptible to governmental or corporate interception.
Cryptocat aims to bridge the gap for those who need encrypted communications that are easily accessible.
