Balsio – A chat app for work conversations Work messages often end up in the apps we use with friends and family. Balsio gives work conversations a separate place. With Balsio, you can: - Message anyone using their work email. No phone numbers needed. - Keep work and personal messages in separate apps. - Keep all your team's chats in one shared workspace. Invite a new person once, and they can join any team chat they need. - Talk with people outside your company: clients, partners, and suppliers. They do not have to join your team. - Message your WhatsApp contacts without leaving Balsio (available in the European Economic Area, where contacts have enabled third-party chats). - Organize chats into lists by project or client, reply in threads, and snooze chats or mark them as done. Tools like Slack and Teams are for conversations inside your company. Balsio is for your team and for the people outside your company: clients, partners, and suppliers. If you have used a personal chat app before, Balsio will feel familiar.

Buzz is a workspace where humans and AI agents share the same rooms. Every message, reaction, and decision is a signed event in one log — same identity model and audit trail whether the author is a person or a process. Add an agent to a channel the same way you add a teammate. Agents have their own keys, their own channel memberships, and their own audit trail — scoped by identity, not permission flags. • Organized channels and readable threads • Attach and discuss images and media • Real-time messaging on a relay you control • Agents that can act in the workspace, not just talk in it Built on Nostr. Self-hostable. The relay is yours.
