Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 12 of the 51 other AI agents we grade
Sauna is an AI agent from Wordware that connects to your work tools, keeps a persistent memory of how you and your team operate, and carries out tasks in the cloud. You can use it in the web app or iOS app, or message it through iMessage, Slack, email or Superhuman, and it can run scheduled tasks and build small apps on request. A free plan gives a daily credit allowance; paid plans are flat monthly prices that differ by models, credits and sharing features.
To get you started, here are 9 things to know about Sauna, taken from its own pages and our grades.
Credits have no published rates, billing is monthly only, and there's no Android or desktop app.
- 1
Best for an agent with memory you can message from anywhere
Sauna is an agent that keeps one memory of how you work across the web, iMessage, Slack and email.
- 2
Paid plans start at $29 a month
As its pricing page puts it: $29 per month, billed monthly (Lite).
- 3
There is a free plan
100 credits per day, or 200 with a verified payment card on file, and no monthly allowance. Unused daily credits do not roll over.
- 4
It runs on 2 platforms
Web and iOS.
- 5
One agent on several surfaces
The same agent and memory are available in the web app and iOS app and by iMessage, Slack, email and Superhuman, including by forwarding a message or copying Sauna on a thread.
- 6
Persistent memory
Keeps workspace notes for lasting preferences and conventions alongside a searchable history of past conversations, so a new session starts with context.
- 7
Scheduled tasks
A saved prompt can run once, hourly, daily, on weekdays or weekly, with the result delivered to the web dashboard, iMessage or email.
- 8
A 2.2 GPA, above 12 of 51
That is against the other AI agents we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace Sauna you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for an agent with memory you can message from anywhere
Sauna is an agent that keeps one memory of how you work across the web, iMessage, Slack and email. The free plan is 100 credits a day with no monthly allowance, and the paid ladder is steep: $29 gets only the Lite model, every AI model means $99, and browser automation sits on the $999 Team plan. Credits have no published rates, billing is monthly only, and there's no Android or desktop app.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | Lite is $29 a month when agent tools here sit at $21.25 in the middle, and it runs only the Sauna Lite model. All the AI models mean Basic at $99, shared folders Pro at $299, browser automation the $999 Team plan. Billing is monthly only, no yearly discount. The useful parts sit a long way above the middle. |
| Free plan and trial | C | There is a free plan and no card needed: 100 credits a day, or 200 if you do add one. But it resets daily with no monthly allowance, nothing rolls over, and Sauna publishes no rates for what a task costs. So it's a cap you'll hit without seeing it coming. |
| Features | B | It covers the whole job. One agent and one memory across web, iPhone, iMessage, Slack, email and Superhuman; notes on your preferences plus a searchable history; saved prompts on an hourly, daily or weekly run; thousands of connections; and small apps built on your own data. Its rivals do much the same, so no A. |
| Ease of use | C | No store rating on record, and you don't just open it and go. Connecting your tools comes first, app by app and account by account. After that, you message it the way you'd text a colleague. |
| Platforms and integrations | B | A web app and an iPhone app, no Android listed and nothing for the desktop. On the connecting side: iMessage, Slack, email and Superhuman as front doors, thousands of apps behind them, several accounts per app, and custom connections by API key or MCP server. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Sauna is for
- Fits if you want to message an agent from iMessage, Slack or email
- Works for briefings and follow-ups that should run while you're offline
Who it is not for
- Pricey if you want to choose your AI model, because all LLMs start at Basic for $99 a month
- Skip it if you're on Android or want a desktop app, as the only apps are web and iPhone
- Not for you if you like to budget, since credits are metered with no published rates and nothing rolls over
- Watch out: shared folders need Pro at $299, and Brain Access and browser automation only come with Team at $999
- Watch out: billing is monthly only, with no yearly option and no trial on paid plans, and the guide and terms disagree on Pro's credits

12/51
Other AI agents it is graded above
Sauna's GPA of 2.2 is higher than 12 of the 51 other AI agents we grade, and level with 10.
It stands best on features (B, above 27 of 51) and worst on value for money (D, above 0).
Its paid plans start at $29 a month, against a middle price of $21.25 for the category: 28 of the 44 others that charge start lower.
On features, ease of use and platforms it scores 2.7 out of 4. 7 tools score higher and cost less.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Sauna you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 29 of the 51 other AI agents grade higher. It costs $348 a year.
What you could not
- An AI agent, with the models and the safeguards behind it.
- An AI model, which you can rent by the request but not make.
- Connections to other products, each kept working as those products change.
- A tool that builds and hosts other apps.
- A real app for iOS. Something home-made would be a web page.
- Sharing with other people, which means accounts and invitations.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Sauna’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
