“Cryptocat has a simple, countercultural goal: people should be able to talk on the Internet without being subjected to surveillance.” — NYTimes

Cryptocat lets you chat with privacy. It encrypts your chats, is translated into 32 languages and you already know how to use it.

Have encrypted, private conversations.
Cryptocat is free, open chat that aims to provide an open, accessible Instant Messaging environment with a transparent layer of encryption that's easy to use.

Easily have group conversations with your friends without fearing monitoring or interception.

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.
