Please select use case:

Offer one-on-one or group messaging.

Real-time text chat is extremely popular and a great addition to any app. With Agora’s Real-Time Messaging, you can easily incorporate one-on-one or group text and media messaging.

Agora’s RTM also provides device signaling for individual or group call invitations.

Enhance the online classroom with interactivity.

Keep students engaged and give educators the tools they need to teach effectively.

With Agora’s Real-Time Messaging, you can use internal signaling to build interactive features like whiteboards, group chat, media file sharing, and more. Additionally, you can provide teachers with classroom management features such as student lists and hands-up options.

To keep class running smoothly, RTM will let you monitor the quality of the channels and the status of user accounts.

Enhance chat rooms with more features.

While Agora Voice Call makes it easy to embed voice chatting into your apps, Agora’s Real-Time Messaging can help you build a full-featured chat room where participants can text, share virtual gifts, comment live, and ask questions.

You can also use RTM to monitor the host status and number of participants, manage the account list, and perform other channel management tasks to keep things running smoothly.

Bring the full conference experience online.

When it’s impractical or inconvenient for people to gather in a physical space, take the conference online.

Agora’s Real-Time Messaging lets you build conferencing apps that provide texting, whiteboarding, media file sharing, and all the other tools hosts, presenters, and attendees need to make the most of an event.

What’s more, RTM lets you monitor channel status, including the number of participants, active speaker control, and more.

Add call signaling to IoT devices.

Make the Internet of Things more interactive.

With Agora’s Real-Time Messaging, you can integrate signaling services for call invitations, bi-directional monitoring and messaging control between apps and devices like smart watches, home security cameras, and other IoT devices.
