Sauna pulls the samples, ties them to support, and drafts the workpaper — flagging the exceptions for your eyes — so fieldwork stops being copy-paste and reconciliation.
Sauna is an AI agent for auditors that turns fieldwork into reviewed work. It ties transaction samples to the ledger and support and flags every exception, drafts workpapers in your firm's format, chases the PBC list, and documents control walkthroughs — so the judgment stays yours and the legwork doesn't eat the engagement.
What it does
Cross-check a transaction sample against the ledger and the supporting documents, and surface every item that doesn't tie with the line quoted.
Turn a procedure and its results into a clean workpaper in your firm's format, with the exceptions and the conclusion laid out for review.
Track which client-prepared items are still outstanding and draft the follow-up to the controller for each.
Turn a walkthrough conversation or transcript into a documented narrative with the control points and gaps identified.
Put Sauna to work on this.
