Sauna vs Viktor

Sauna

• People who want to message an agent from iMessage, Slack or email
• Small teams that want one agent sharing context and memory
• Recurring briefings and follow-ups that should run while you are offline

Viktor

• Teams that already work in Slack or Microsoft Teams
• Recurring reports pulled from ads, billing and CRM tools
• Small companies that want internal tools built without engineers

Sauna

• The Lite plan runs only on the Sauna Lite model; access to all LLMs starts at Basic for $99 a month.
• Billing is monthly only, with no annual option and no trial period on paid plans.
• Usage is metered in credits with no published per-operation rates, and unused daily and monthly allowances do not roll over.
• Shared folders need Pro, and Brain Access and browser automation are listed only on the $999 Team plan.

Viktor

• Viktor is used through Slack or Microsoft Teams; its site lists no standalone desktop or mobile app.
• The free allowance is a one-time $100 in credits rather than a recurring free plan.
• Everything runs on workspace credits, including scheduled automations, so frequent jobs raise the monthly cost.
• Per-user spend caps, invoicing and custom billing terms are reserved for Enterprise.

Sauna

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.

Persistent memory

Keeps workspace notes for lasting preferences and conventions alongside a searchable history of past conversations, so a new session starts with context.

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.

Connections

A library of thousands of apps that allows several accounts per app, plus custom connections added with an API key or an MCP server URL.

Spaces, Brain Access and Shared Folders

Spaces are shared project workspaces. Brain Access opens your whole Sauna to one person, and Shared Folders share one slice of your knowledge, read-only or read and write.

Apps

Sauna builds small custom apps, such as a CRM or an expense approvals tool, on top of your connected data, with a docked chat for changes and sharing through Spaces.

Viktor

Lives in Slack and Microsoft Teams

Installed from the Slack App Directory or Microsoft Teams and addressed in threads and mentions like a colleague, so everyone on the team can work with it.

Connections to 3,200+ tools

27 native integrations with full read and write access, including Stripe, GitHub, Linear and Notion, plus more than 3,200 tools through managed connectors.

Finished deliverables

Queries connected tools, analyzes the data and hands back outputs such as PDFs, spreadsheets, reports and dashboards rather than instructions.

Scheduled tasks

Recurring work, such as a weekly revenue dashboard or a morning metrics summary, runs on a schedule. Scheduled automations use credits each time they run.

Web apps and code

Builds and deploys internal tools as web apps with a database, auth and hosting, and can clone a repository, write a fix on a branch and open a pull request.

Approvals and activity log

Sensitive actions wait for a person's approval before they run, and Viktor posts back what changed, with its activity logged.
