Main features
Nextcloud Talk lowers the barrier for communications and lets your team connect anytime, anywhere, on any device, with each other, customers or partners.
Unique protection
Nextcloud talk protects your communication better than other team collaboration platforms like Microsoft Teams or Slack, making sure your data stays on your servers.
Nextcloud Talk goes further than other encrypted communication technologies by keeping even metadata from leaking.
This ensures you stay in complete control of communications.
Designed for privacy
Nextcloud Talk is a fully self hosted, on-premises audio/video and chat communication service. It features web and mobile apps and is designed to offer the highest degree of security while being easy to use.
Message status indicators show when a message is sent and received – for more privacy, users can disable this on their side.
Private, group and public calls
Talk makes it easy to call customers and partners in one-to-one or group scenarios. Users can invite external chat participants with an URL into public rooms on the Nextcloud server.
The chat, which remains open even when the user leaves a call, enables participants to easily exchange messages, links and notes.
Configurable visibility on chats allows team members and/or guests to find and join open chat rooms.
Collaboration within Nextcloud
Documents can be shared directly into a chat from the Files app and are made available to all participants, both users and guests. Projects integration enables linking of chat rooms with files, calendars, tasks and other resources for easy finding. Our online office solutions provide a sidebar with Talk for chat and calls with the participants.
Integrated groupware, chat and project management
Nextcloud features tightly integrated chat, project management, mail, calendaring and more. Chat messages can be directly transformed into tasks, task deadlines are visible in the Calendar and files can be attached to a task from the sharing dialog.
A single platform means there is no need to juggle different accounts, keep track of where in the many cloud platforms the latest version of a document is floating around, or worry about security threats and invisible costs.

Nextcloud whiteboard
One application that is very useful during audio/video calls or chat sessions is Nextcloud Whiteboard. It is a collaborative whiteboard with the ability for all participants to draw lines and shapes, take notes and write text, upload images, give a presentation and more.
Files created with Whiteboard are saved among other regular files and can thus easily be shared.
Bridging with other networks
Nextcloud Bridging allows the connection of Talk rooms to one or more channels on other Talk servers, but also other services like IRC, Slack, Microsoft Teams, Matrix, Mattermost, XMPP and many more. A bridge sends any messages from the third party network into the Talk room where it was configured, and any messages put in the Talk room to the bridged third party network.
Multiple networks can be bridged into a single Nextcloud Talk room, so messages can go from Slack to Teams and IRC via Nextcloud.
Webinars and presentations
Share the content of a single window or a full desktop screen for presentations with chat-partners.
Manage participants permissions for audio/video and screen sharing.
Schedule meetings and be notified when they start.
A lobby is provided for guests to wait until the call starts. Moderators can let a selected guest in early.
Participants can raise their hand to get attention or be allowed to speak.
Video verification
In situations where extreme security is warranted and the identity of a recipient has to be verified with absolute certainty before they are granted access, Nextcloud includes the industry-first implementation of Video Verification.
Video Verification enforces a Nextcloud Talk video call before access is given to a share, making sure the identity of the recipient is properly checked. The call can be picked up through the Nextcloud Talk Mobile apps as well as the web interface.
