Kylon vs Sauna
Sauna is one AI teammate that follows you. Kylon gives you a team of them.
Sauna is an agent that learns how you work and meets you on every surface, from iMessage to Slack. In Kylon each agent has its own role, memory and permissions, works in rooms next to your people, and brings the result back to the thread for approval.
01 In the product
Two agents on October renewals, one approval, and the account log in the same room.
The request is the one a customer success lead sends every week: which renewals are at risk, and what to do about them. One agent reads HubSpot, PostHog and Zendesk and proposes three actions, a second sends the update once it is approved, and the Accounts app pinned to the room keeps the log as a table or a dashboard. The frame below is live, so open the Accounts tab yourself.
One room, three tools, a mailbox and an Accounts app. One approval covers the account actions and the update, and the same log reads as a table or a dashboard. Click the tabs. Illustrative data.
02 Which one is the right answer
Not every team should pick the same one.
Sauna is the right answer when
Each person wants an assistant that learns their way of working and reaches them wherever they are, from iMessage to email, with colleagues able to tap into it.
Kylon is the right answer when
The work belongs to the team: several agents with different roles carry parts of it, people approve the results in the room where the work is discussed, and the output stays as records anyone can open later.

What the AI is
A proactive AI teammate with a computer of her own. She learns how you and your team work, remembers what matters, and acts on your behalf.
Source: Sauna homepage and FAQ
Several agents, each a member of the workspace with its own name, role, memory, skills and permissions. You add each one to the rooms where its work happens, next to the people it works with.
Where you ask
Wherever you work: the web app, iOS, iMessage, Slack or email. One agent with the same memory on every surface.
Source: Sauna FAQ, Where can I use Sauna
In a room in the Kylon workspace, on the web or on the phone. The request, each agent's reply and the approval stay in one thread, and Slack stays connected so an agent can read and post there too.
Working as a team
Teammates share a Sauna's context and memory, and each person's Sauna can ask a colleague's Sauna a question or pull their knowledge without interrupting them.

People and agents share a room: its thread history, files and the records the work touched, so everyone sees the same request and the same result.
Reaching your tools
Connects to over 3,000 tools and apps, including Linear, GitHub, Notion, Gmail, Google Calendar, Jira, HubSpot and Stripe, plus custom MCP connectors.

Connections to the accounts the team already uses, granted per agent so each one reaches what its role needs.
Repeat work and results
Runs in the cloud around the clock, drafting messages in your voice, filing tickets and delivering briefings, with routines and apps she builds.

A run you want again is saved as a workflow on a schedule or trigger that posts into the same room, and structured results land as records in a Database App pinned to that room.
Questions people ask
- Sauna is a proactive AI teammate. What is different about Kylon?

- No. Slack is a connected service in Kylon, so an agent can read and post there while the work, the approvals and the records live in the workspace.
- Does anything get sent or changed automatically?
- Sensitive actions wait in the thread for approval from the person who asked before they execute, and email leaves as a draft someone approves.
