Drop in the receipts and the statements; Sauna reconciles, builds the report, and chases the missing documents — so close and reporting stop eating your week.
Sauna is an AI tool for accountants and auditors that turns receipts, statements, and ledgers into finished work. It reconciles transactions, flags anomalies and duplicates, builds expense and close reports, and chases the missing documents — so month-end and reporting stop eating the week.
What it does
Turn a folder of receipts or a statement export into a clean spreadsheet — categorized, totaled, with duplicates and odd charges flagged.
Cross-check transactions against your ledger and surface what doesn't match, with the line that needs your eyes quoted.
Find which receipts or approvals are outstanding and draft the follow-up to whoever owes them.
A recurring close summary — what's reconciled, what's open, what's unusual — on the schedule you set.
Put Sauna to work on this.

Sauna shows up where you already work — the web app, Slack, email, iMessage, and Superhuman. It reads what it needs, does the task, and comes back with the draft for your approval.

The literal prompt for this job. Open it in Sauna and it picks up from there.
“Take the receipts in this folder and build an expense report with vendor, date, category, and amount, totals by category, and a flag on anything that looks like a duplicate or a personal charge.”
Plugs into the tools you already run — and thousands more, or any MCP server.
What you get
Reports, drafts, and dashboards Sauna assembles from your live tools — kept current on its own.
Get the result, not the busywork.

No. Sauna builds the report and flags the issues; posting or editing in your accounting system waits for your approval.
Yes, plus Stripe, your bank exports, and spreadsheets — or anything else over an API key or MCP server.
Sauna reads only what you connect, and acts only after you approve. Your workspace and its memory are yours, not training data.
