CTalk is different from other messaging and collaboration apps. It operates on Matrix, an open network for secure and decentralized communication. It allows self-hosting to give users maximum ownership and control of their data and messages.


Privacy and encrypted messaging:

CTalk protects you from unwanted ads, data mining and walled gardens. It also secures all your data, one-to-one video chats and voice communication through end-to-end encryption and cross-signed device verification.


CTalk gives you control over your privacy while allowing you to communicate securely with anyone on the Matrix network, or other business collaboration tools by integrating with productivity apps such as Slack.

Own your data:

You decide where to keep your data and messages. Without the risk of data mining or access from third parties.

Open messaging and collaboration:

You can chat with anyone on the Matrix network, whether they’re using Element, another Matrix app or even if they are using a different messaging app.


Super secure:

Real end-to-end encryption (only those in the conversation can decrypt messages), and cross-signed device verification.


Complete communication and integration:

Messaging, voice and video calls, file sharing, screen sharing and a whole bunch of integrations, bots and widgets. Build rooms, communities, stay in touch and get things done.
