Sauna

What is Sauna?

Sauna is a collaborative AI workspace built by HeyDaily that goes beyond a typical assistant — it functions as a persistent, context-aware coworker for individuals and teams. It integrates with your existing tools (email, Slack, iMessage, Superhuman, and 3000+ more), remembers how you work across sessions, and acts autonomously in the cloud even when you're offline. Its standout 'multiplayer' feature lets teammates access each other's Sauna agents directly, enabling shared knowledge and collaborative workflows without interrupting one another.

Key Features

• Persistent Memory

  Maintains two layers of memory — workspace-level notes for standing context and session memory for recent interactions — so Sauna always knows where things stand without being re-briefed.

• Multiplayer Collaboration

  Team members can query each other's Sauna agents directly, access shared folders, or enable Brain Access to tap into a colleague's full knowledge base without interrupting them.

• Always-On Autonomous Execution

  Runs in the cloud 24/7, handling drafts, tickets, briefings, and scheduled workflows whether or not you're logged in — up to 500 concurrent agents simultaneously.

• Multi-Surface Availability

  Accessible via web app, iMessage, Slack, email forwarding, and Superhuman, keeping the same context and workspace synced across all surfaces.

• Universal Tool Integration

  Connects to 3000+ apps via OAuth and API, allowing Sauna to read, act, and automate across email, calendar, project management, and messaging tools.

• Model Flexibility

  Provides access to all major LLMs with options for custom models on higher tiers, so teams aren't locked into a single AI provider.

Use Cases

• Async Team Coordination : Teams can delegate cross-functional tasks to Sauna agents, query a colleague's Sauna for context, and keep projects moving without constant back-and-forth communication.
• Email & Inbox Management : Professionals can forward emails to Sauna or CC it into threads; it triages, drafts replies in your voice, and schedules follow-ups automatically.
• Scheduled & Recurring Work : Operations and project managers can set up recurring workflows — briefings, status reports, ticket filing — that Sauna runs on a timer without manual triggering.
• Knowledge Management : Teams can store files, SOPs, and institutional knowledge in Sauna's persistent file system, making it instantly retrievable for future tasks and new team members.
• On-the-Go Task Delegation : Mobile users can send voice notes or screenshots via iMessage and Sauna picks up the context, acts on it, and reports back — no app-switching required.
