Why Sauna

Built around your work.

General
Not bound to one domain
Sauna isn't a tax product — it researches, drafts, files, and follows up across whatever your work touches, from a launch plan to a customer reply.
Memory
It remembers your work
Workspace notes hold what should stay true; session memory holds what's been said. You stop re-briefing it each morning.
Connected
Your whole stack
Connect thousands of apps, more than one account each, or your own tool with an API key or MCP server from chat.

In context

It knows your work, and acts on it.

Sauna remembers your projects and the people in them, connects to the tools your team runs, and finishes the task — across the web app, Slack, email, iMessage, and Superhuman.

Good to know

Questions, answered.

Can Sauna do my taxes like Town?

Sauna can research tax questions and pull numbers from the tools you connect, but it isn't a licensed tax service with human advisors. For end-to-end filing, a vertical like Town is purpose-built; for everything around it, Sauna is the coworker.

Why not just use a specialist tool?

Specialist tools are great inside their lane. Sauna is the generalist that handles the rest of your work and remembers the context across all of it, instead of one task per app.
