What it does
Sauna is an agent that picks up how a person or team works, remembers what matters and acts on their behalf. According to the site, the more context it has from emails, documents, Slack messages and files, the more it can do. It runs in the cloud continuously, so it can draft messages in your voice, track topics, file tickets and deliver briefings while you are offline. The site also mentions routines and apps that Sauna builds, and shows it querying a connected analytics tool to answer a question in Slack. Sauna connects to thousands of tools and apps, among them Linear, GitHub, Notion, Gmail, Jira and HubSpot, and accepts custom MCP connectors. It can be used from a web app, iOS, iMessage, WhatsApp, Slack or email, and teammates can share one Sauna's context and memory. The site states SOC 2 Type II compliance and says user data is not used for model training.
