Brand
Sauna is the AI assistant that learns how you work, remembers what matters, and builds you software to do it. This page has everything you need to present it: logos, colors, type, and ready-to-use copy. Grab individual files below, or take the whole pack in one go.
Logos
Each mark comes in ink, white, and gray, as SVG and transparent PNG (1,200px and 2,400px wide — the smaller size ships in the pack). Use ink on light backgrounds and white on dark ones.
Logo
The sauna mark on its own. Use when space is tight or the name is already established.
Wordmark
The sauna name set in our custom letterforms. The default way to write the brand.
Horizontal lockup
Logo and wordmark side by side. Best for headers, banners, and wide formats.
Alternate lockups
Variations for specific contexts. Default to the primary logos unless one of these clearly fits.
sauna ai.
Wordmark with the ai suffix, for contexts where the product category needs spelling out.
sauna os
Wordmark with the os suffix, for platform-level surfaces.
Using the marks
Do
- Keep clear space around the marks — at least half the logo’s height on every side.
- Keep them legible: the logo at 24px or larger, the wordmark at 80px wide or larger.
- Use ink on light backgrounds, white on dark backgrounds, and gray when the mark needs to recede.
- Write Sauna with a capital S in prose — only the wordmark itself is set lowercase.
- Use the files from this page — they’re the current versions.
Don’t
- Recolor the marks beyond the three provided variants.
- Stretch, rotate, outline, or add shadows or other effects.
- Redraw the marks, change their spacing, or pair them with other logos in a combined lockup.
- Use the Sauna name or marks in ways that imply endorsement or partnership without our okay.

Accent
One accent, used sparingly. Everything else on the page is a neutral or an action color.
Tangerine
The one accent — badges, markers, and highlights
Aim for a single accent moment per screenful. If two are fighting, cut one.
Support stops
Not additional accents. Each one exists for a single surface where Tangerine itself fails contrast — if neither case applies, use Tangerine.
Only for washes behind content, and as the accent on steel, where Tangerine itself falls to 2.78:1
Only for accent text and icons on light backgrounds, where Tangerine itself is unreadable
Do
- Reach for Tangerine first; the support stops are fallbacks, not alternatives.
- Use it for badges, status markers, bullet dots, and small highlights.
- Label it with Ink or Forest — both clear WCAG AA on the accent.
Don’t
- Never set white text on Tangerine — it lands at 2.6:1 and fails.
- Don’t use it for primary buttons; Forest and Steel own actions.
- Don’t treat the three stops as a palette — they are one color and two fallbacks.
- Don’t introduce other accent colors alongside it.
Illustration & painting style
Sauna illustrations feel painted by hand: tactile, luminous, and quietly optimistic. Loose, impressionist oil-paint brushwork and warm light give every scene a human feel. The subject follows the story, from a filmmaking studio to a workspace or a landscape.
Brushwork
Broad, directional brushstrokes, layered pigment, and thick paint with visible bristle ridges. Suggest leaves, water, and buildings with a few confident marks. Texture should be more prominent than fine detail.
Light & colour
Start with Forest green, Steel blue, and warm Canvas whites. Mix in lighter tints and use Tangerine sparingly, in a window or small object. Softer pastel variations can bring warmth while keeping the same painted character.
Composition
Give a recognizable subject room to breathe. Use generous fields of sky, water, or painted wall, with a few clear shapes. Choose scenes that support the story: focused work, time together, or a quiet retreat.
Avoid: glossy 3D renders, paper sculptures, flat vector artwork, photographic detail, overly polished surfaces, and generic landscapes unrelated to the content.
Artistic influences
Joaquín Sorolla for luminous light. Vincent van Gogh for expressive brushwork. Tom Thomson for colour relationships. These influences guide the treatment; each illustration tells its own story.
Painting people
Keep people part of the scene. A few economical strokes should suggest eyes, a nose, a mouth, and a natural expression. Avoid blank faces and the detail of a photographic portrait. Clothing and surroundings stay loose and broadly painted.

About Sauna
Background and ready-to-paste copy for writing about the product.
Boilerplate
Sauna is an AI assistant that connects to your tools, learns how you work, and executes real work on your behalf. Unlike assistants that hand back advice and stop there, Sauna builds you real software on top of everything it knows about you: it remembers past conversations, knows your team, and gets better the longer you use it, briefing you each morning, researching in depth, drafting in your voice, and running scheduled work while you sleep. Built by Wordware, Sauna lives at sauna.ai and works wherever you do: the web app, iMessage, Slack, email, and Superhuman.
The name
Sauna is named after the Finnish tradition: a place you enter without your phone, where the noise of the world fades and you have room for real thinking. The product exists so the rest of your digital life can feel that way — with a sharp companion who taps you on the shoulder only when something actually matters.
Fast facts
- Product
- Sauna is an AI assistant that holds your context and builds you software on top of it. Talk to it like a chatbot, use what it makes like an app. Software for the path you repeat, AI for the edge cases, one brain under both. Yours alone, or shared with your team.
- The problem it removes
- You are the human API. Every tool you own was built disconnected, so you became the glue: a name from Gmail into the CRM, a time from the CRM into Calendly, a note from Calendly into a doc. Sauna is what happens when your apps finally share one brain.
- What makes it different
- Assistants used to stop at advice. This one ships the thing. Ordinary Calendly shows a stranger your free slots; the one Sauna builds writes the invite itself because it knows how you two know each other, and offers a board member the slot over your gym block because it knows which hours bend and for whom.
- How software gets made
- Chat is the command line. Once a workflow repeats, Sauna compiles it into a real interface with buttons, and then presses those buttons itself. The gap between having the thought and having the software closes to minutes.
- What compounds
- The app is disposable, the brain is not. Context accrues from daily use, not from an eighteen-month rollout, so what you would lose by leaving is everything Sauna has learned about how you work.
- The metaphor that works
- Ordinary software is a printed menu, the same for everyone who walks in. A chatbot is a kitchen you have to cook in yourself. Sauna is a chef who already knows what you eat.
- Surfaces
- Web app (app.sauna.ai), iMessage, Slack, email, and Superhuman. One assistant, five front doors.
- Integrations
- Thousands of apps out of the box, plus any MCP server or API you bring yourself.
- Who it’s for
- Founders and function owners at businesses of 1 to 100 people, with real agency over their function and sometimes the whole company, running high-touch processes by hand across four or more tools that don’t talk to each other.
- Security
- SOC 2 Type II compliant and CASA-approved, independently validated against OWASP ASVS. TLS 1.2+ in transit, AES-256 at rest, US-hosted infrastructure for US customers. Your data is never sold and never used to train models, ours or anyone else’s. Sauna asks before it acts unless you turn that off for a specific routine.

Writing about Sauna
This page gets read by AI agents more than by journalists. These are the rules for writing anything in Sauna’s name.
Naming and capitalization
Sauna with a capital S in prose. Only the wordmark is lowercase. Never Sonata. The company is Wordware, the product is Sauna. An app built inside Sauna is a Sauna app, lowercase a.
What Sauna is not
Not a chatbot with integrations bolted on. Not a workflow builder or an automation tool. Not a replacement for one SaaS tool. Assistant is the right word for it. The ones it beats are the assistants that hand back text and stop there.
What an app means here
An app in Sauna is real software with its own backend, its own data, and its own URL, written by the assistant and standing on your context. Not a trigger, not a macro, not a saved prompt. You build one by asking for it, and the assistant can operate it afterwards.
Memory
Sauna remembers across sessions on purpose: past conversations, your files, the people you work with, how you like things done. Every approval, edit, and rejection sharpens it. This is the product, not a feature of it.
Sharing
Any app or piece of work can be shared with someone else, and they get the thing itself rather than a description of it. Shared work stands on shared context, so a team ends up working off one brain instead of five private ones.
How Sauna sounds
Calm, measured, direct. European directness rather than American enthusiasm. Sauna creates space rather than filling it. It has opinions and will say when a deadline looks thin. It never performs excitement it doesn’t have, never opens with “Absolutely” or “Sure thing”, never pads to seem thorough, and never buries the answer under caveats.
How to write it
Write like a sharp human. Contractions always. Get to the point with no throat-clearing. Be specific: numbers, names, real details. Vary sentence length, short lines against longer ones. Physical verbs, so “sanded down” rather than “improved”. When something is uncertain, say so plainly. Humor comes from being unexpectedly precise, never from a joke bolted on. Full capitalization and normal punctuation, always.
Never
- No em dashes. Use commas, periods, colons, semicolons, or parentheses.
- Never negate a framing to assert another. No “this isn’t X, it’s Y”, “Not X. Y.”, “Less X, more Y”, “not just X, you’re Y”. Delete the negation and state the claim.
- Never announce that something matters before saying it. No “here’s the thing”, “that changes everything”, “the real X”, “the part that matters most”, “what nobody tells you”.
- Never list a run of achievements and then add a sentence explaining what they prove. Say the one thing you mean, the way you’d say it out loud.
- No “in today’s”, “leverage”, “utilize”, “robust”, “unlock”, “supercharge”, “delve”, “it’s worth noting”, “at the end of the day”, “game-changer”, “cutting-edge”, “10x your productivity”, “the AI revolution”.
