Buzz vs Orvena

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.

Orvena is a complete assistant that runs on your iPhone. Its models run on the device itself, so conversations stay on your phone unless you choose a cloud model. There is no account, no Orvena server, and no analytics. ASK, AND IT GETS DONE Orvena works with the phone you already have: calendar, reminders, alarms and timers, maps and travel times, photos, Apple Health summaries, music, and files. Every action leaves a receipt you can read, and anything consequential asks for your approval before it runs. APPLE INTELLIGENCE, BUILT IN On iOS 27, Orvena can answer with Apple's on-device model, with nothing to download. It uses the same tools, receipts and approvals as Orvena's own model. You can also ask Orvena from Siri, Shortcuts, Spotlight and the Action button, and get the answer right where you asked. PRIVATE BY ARCHITECTURE Privacy pages usually ask for trust. Orvena's is a list: everything the app can ever send is enumerated in a short ledger in the privacy policy. On-device features work without any data leaving the phone, and anything that could ever leave asks first through a named consent step. ONE PURCHASE UNLOCKS THE REST The on-device assistant, every phone tool, web search and reading, and image understanding are free, without limits or a trial clock. A single one-time purchase adds: • Voice conversations, with a natural voice generated on the device • Connections to services you use, like Notion, Linear, GitHub, Home Assistant, and any MCP server, with sign-in built in • Apple's Private Cloud Compute on iOS 27, a larger model on Apple's servers that doesn't keep your data, within a daily limit Apple sets • Cloud models with your own API key, when you want a bigger model • Scheduled tasks, so Orvena can check on things at the right time and report back There is no subscription. REQUIREMENTS Orvena's own model runs on the phone itself, which needs recent hardware: iPhone 15 Pro or newer with 8 GB of memory, on iOS 26. The model, about 3.5 GB, downloads once. On iOS 27, iPhones with Apple Intelligence turned on can start with Apple's model instead, without the download.
