Use tool ↗About Sauna
Sauna is a cloud-based AI assistant that keeps long-term memory of your emails, documents and chats, drafts in your voice and learns recurring work well enough to offer to run it automatically. You reach it from a web app, an iOS app, iMessage, Slack or email, and it connects to thousands of tools plus custom MCP connectors. Teams can share context and memory between members. It is the new main product of Wordware, whose earlier workflow-builder platform for turning plain English into AI flows was set aside in 2025 in favor of this assistant.

Pros & cons of Sauna
An interesting bet for professionals who want an assistant that remembers context and gradually takes over repeat chores, reachable from the chat apps they already use. It is aimed at knowledge work rather than coding. Pricing starts at $29 a month and climbs quickly, and the product is young, so try the free start before committing a team.
Pros
- Persistent memory is the core of the design
- Reachable from web, iOS, iMessage, Slack and email
- Thousands of integrations and custom MCP connectors
- States SOC 2 Type II compliance and no training on user data
Cons
- Monthly billing only, with no annual discount
- Upper tiers are expensive, with Team at $999 a month
- Free allowance is described two different ways on the site
Best for
- Founders and operators who want one assistant across iMessage, Slack and email
- Teams that want shared memory and routines for recurring work
Not for
- Developers who want a workflow builder or SDK, which Wordware's earlier product offered
- Budget buyers, since the cheapest paid plan is $29 a month and the team tier is $999
Watch out: This is the product Wordware pivoted to in 2025; the older Wordware workflow IDE and its docs still exist, but the company now presents Sauna as its main product, so check which one a tutorial or review refers to.
