Sauna vs ChatGPT

ChatGPT forgets. Sauna remembers.

ChatGPT starts every chat from zero. Sauna already knows your work. It remembers what you've done, connects to the tools you use, and does the task instead of describing it.

@Sauna what did we land on for pricing last week, and draft the update?

SaunaAPP9:14 AM

Pulling last week's #launch thread and your workspace notes.

You settled on three tiers. Drafted the page copy:

A chat window has no memory of your work.

Every ChatGPT thread is a blank slate, so you keep pasting the same context back in. Sauna holds two kinds of memory instead: a durable record of your workspace, and a searchable history of what's been said. It picks up where you left off and acts on what it already knows.

The difference

Two memories that work together: what should stay true, and what was said.

Lives in the stack you already run — and thousands more, or any MCP server.

SaunaAPP2:03 PM

Posted to #product and tagged #eng. The release email draft has it too, ready for your okay.

It already has the context

No re-briefing. Sauna pulls the thread and your notes, then drafts, because it remembers the decision you made.

@Sauna pull our Q2 numbers and turn it into a one-page board update.

SaunaAPP11:30 AM

Querying the sheet, charting it, exporting to PDF.

Tasks · 3 done

One-page board update is ready as a PDF.

Dax Kim11:31 AM

@Sauna send it to the board list.

SaunaAPP11:31 AM

Sent to board@ with the PDF attached, and saved a copy to the Board folder.

A finished file, not instructions

Sauna can research, run code, and hand back something finished. Ask for a board update and a Markdown doc comes back as a PDF, ready to send. ChatGPT tells you how. Sauna does it.

No more general LLM tools — it's just superior in every way.

What Sauna does

Built around your work, not a chat box.

Memory

It remembers your work

Workspace notes hold what should stay true. Session memory holds what's been said. You stop re-briefing it every morning.

Action

It runs the task

It reads files, runs code, and researches, then gives you something finished: a doc as a PDF, a draft ready to send.

Connections

Wired into your stack

Connect thousands of apps, with more than one account each if you need it. Anything missing, you add with an API key or an MCP server from chat.

Everywhere you already work

One coworker, on every surface you use.

Web app

Sessions, knowledge, and scheduled work in one tab.

iMessage

Text it. Voice notes, screenshots, replies in the thread.

Slack

DMs, channel mentions, full threads, a live Tasks panel.

Forward to hey@sauna.ai or CC it into any thread.

Superhuman

Tag Sauna in a comment and it picks up the thread.

Good to know

Questions, answered.

Isn't this just ChatGPT with plugins?

No. Sauna remembers your work, connects to your real tools, and finishes tasks across Slack, email, and the web. It isn't a chat box you re-prime each session.

Does it act without asking?

Anything that writes to your tools waits for your approval. Sauna drafts it; you decide whether it goes.

Where does it run?

The web app, iMessage, Slack, email, and Superhuman. It's the same Sauna everywhere.

Is my data safe?

Sauna reads only what you connect, and acts only after you approve. Your workspace and its memory are yours, not training data.
