01 · The app and the agent

Buttons for speed. Chat for infinite reach.

Software shouldn't be a cage. Start in chat, and when a task repeats, Sauna crystallizes an interface over it. Use the buttons for speed. If you hit an edge case or need a new button, tell the docked chat. It already knows your business.

02 · The end of the integration tax

Stop paying for disconnected silos.

Every app inherits Sauna's central intelligence. Pull PostHog usage and trigger a Superhuman email from the same interface, because the agent securely manages your credentials. Apps talk to each other too — a win-back closed in one shows up in the next — and everything they learn flows back into Sauna. Zero Zapier required. Enterprise compliance by default.

03 · Multiplayer by default

Share the app. Keep control.

Add a teammate to a Space and they instantly get access to your apps. Granular permissions keep you in control. They get a focused dashboard; your agent does the heavy lifting securely behind the scenes.

04 · Mission control

Ask a question. Get a dashboard.

The same apps that do the work can show the work. Ask for a view — revenue against usage, pipeline, support load — and Sauna assembles it over your live tools, then keeps it fresh while you sleep.
