Sauna
AI teammate with memory, reachable by web, iMessage, Slack or email
Sauna report card
Very good · out of 4.0 · graded Oct 9, 2026
Best for an agent with memory you can message from anywhere
Sauna is an agent that remembers how you work. Message it from the web, iMessage, Slack or email and the same memory comes along, so you don't start from scratch each time. There's a free plan with 100 credits a day, but the paid ladder is steep: $29 a month gets only the Lite model, and every AI model means $99.
Who Sauna is for
- Great if you want to message an agent from iMessage, Slack or email
- Handy when a small team wants one agent sharing context and memory
- Good for briefings and follow-ups that should run while you're offline
Who Sauna 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, as the only phone app listed is for iPhone
- Not for you if you like to budget, since credits are metered with no published rates
Why Sauna gets a 3.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyLite is $29 a month, at the top of what agents usually start at, and it runs only on the Sauna Lite model. All the AI models need Basic at $99, shared folders need Pro at $299, and browser automation is on the $999 Team plan. There's no yearly discount.
- BFree plan and trialFree for good: 100 credits a day, or 200 with a verified payment card on file. But there's no monthly allowance, unused credits don't roll over, and Sauna publishes no rates for what a task costs. So how far 100 goes is anyone's guess.
- AFeaturesThe same agent and memory follow you across the web app, the iPhone app, iMessage, Slack and email. It keeps notes on your preferences plus a searchable history, runs saved prompts hourly, daily or weekly, and connects to thousands of apps. It can even build a small CRM or approvals app on your data.
- BEase of useYou message it like a teammate, forward it an email, or copy it on a thread. Connecting your tools comes first. There's no rating on record to go by, so a B.
- BPlatforms and integrationsA web app and an iPhone app, plus iMessage, Slack, email and Superhuman. No Android app is listed. It connects to thousands of apps, with several accounts per app, and takes custom connections by API key or MCP server.
