Sauna 2.0

A manifesto for not working at your computer

Sauna 2.0 is here. It works in Slack, WhatsApp, iMessage, Email and Superhuman. It answers your messages as you, on LinkedIn and Instagram too, and it messages you first. So you can get up and go outside.

You weren’t made to sit all day.

People are made to walk, swim and be outside. Instead, most of us sit at a desk all day and answer messages.

We tried to fix it with standing desks. Then treadmill desks. Now we walk all day and still go nowhere.

Our idea is simple. The computer should do the computer work. You should go and live your life.

1 · Before80 °C

Sauna used to live in a tab

The first Sauna lived in your browser. It remembered what you told it and did real work: replies, briefings, tickets.

But you had to sit down, open the tab and ask. So it still kept you at your desk.

Sauna 2.0 comes with you

Sauna now works in the apps you already use. Talk to it on WhatsApp, or in Slack, iMessage, Email and Superhuman. It’s the same Sauna everywhere, and it remembers everything.

3 · While you’re out21 °C

It messages you first

You don’t have to ask. Sauna reads everything that comes in: your email, Slack, LinkedIn, Instagram and WhatsApp. It writes the replies as you, moves meetings and follows up. Then it sends you a short note about what it did.

Read it wherever you are. Reply if you want. Or don’t, and it keeps going.

4 · On your behalf60 °C

It writes to people for you

Sauna can also message people without you asking. A thank-you after a call. The follow-up nobody chased. A quick yes to a time that works.

You always stay in control. You decide what it can send on its own, and what it should check with you first. Everything it sends, you can read.

5 · When it needs you80 °C

It calls you back in

Some things need you: a decision, a yes or a no. When that happens, Sauna lets you know. You do that one thing. Then you go back outside.

It works like a sauna: hot, cold, rest, repeat.

Our promise · Say it out loud. Towel optional.

I won’t open my laptop just to answer a message.
I won’t walk on a treadmill under my desk.
I won’t keep tabs open just in case.
I’ll let Sauna write first.
I’ll let Sauna answer for me, and keep the final say.
I’ll come back when I’m needed. Not before.

Close the laptop. Go outside.

Sauna 2.0 is out now on Slack, WhatsApp, iMessage, Email and Superhuman. It answers for you on LinkedIn and Instagram too. Set it up once. Then go outside.
