An AI assistant for copywriters
Sauna researches the audience, drafts the variations, and keeps every brief and revision in one place — so you spend your time on the line that lands, not the legwork around it.
Sauna is an AI writing assistant for copywriters that takes the legwork around the line. It researches audience language and proof, drafts genuinely different variations on a brief, adapts copy to every format, and keeps the brief, the approved version, and the edits in one place — so your time goes to the words that land.
What it does
What Sauna does for copywriters
- 01
Draft variations on a brief
Turn a brief into ten headline, subject-line, or hook variations in the voice you specify, each a genuinely different angle — not a reworded copy.
- 02
Research the audience and the proof
Pull the reviews, the competitor messaging, and the customer language for a product into a swipe of real phrases you can build copy from.
- 03
Adapt copy to every format
Take an approved long-form piece and cut it down to ad copy, an email, a landing hero, and a one-line tagline — each rewritten for the format.
- 04
Keep briefs and revisions straight
Hold the brief, the approved version, and the round of edits per project in one place, and draft the revision from the client's notes.

The literal prompt for this job. Open it in Sauna and it picks up from there.

Questions, answered.
Won't it all sound the same?
No. Sauna researches the actual audience language and writes genuinely different angles per variation — and it learns your voice from the work you approve.
Can it match a client's tone?
Yes. Give it a few approved samples or the brand guide once; its memory keeps each client's voice so drafts come back on-brand.
Is my data safe?
Sauna reads only what you connect, and acts only after you approve. Your workspace and its memory are yours, not training data.
