Proactive agent that thinks and acts like you.
Multiplayer AI Brain for teams.
Proper GUI for commanding 50 agents.
Sauna.ai is all three. Sauna goes live today. First 2000 people, use access code LAUNCH for $80 of weekly(!) credits.
Let’s explain. Multiplayer only works once the personal brain is powerful. So let's start here.
Personal AI Brain
3,800+ tools connected. State of the Art memory. Skills and schedules you teach once that get repeated forever on cheaper models. An AI first CRM.
Lives on the cloud so you can initiate tasks from anywhere: iMessage, Slack, Email. Also no need for a Mac mini 😉
GUI
AI agents have been stuck in their MS-DOS era. A chat box, a scroll buffer, no way to command 50 of them. We built the first GUI: Live sessions on one side, work waiting for your sign-off on the other, plus the things Sauna kicked off while you were asleep waiting for review. Game mode helps clear the queue with actual joy.
Okay so far so good, but how to give benefit of what you built to more people or whole team?
Multiplayer
Once your Sauna actually knows you and you gave her access to your tools, you can use multiplayer.
Two modes:
- Brain access. My co-founder Robert plugged my brain as a tool into his Sauna last month. He can ask it about pricing while I'm in other meetings, gets a sourced answer back, never has to interrupt me. That’s read only. Yolo mode gives him access to all my tools too :O
- Communal Saunas extend that to whole companies with proper permissioning. Folder owners decide what's true for the whole company and build skills. Most get their personal brain + read access to communal files and memories. Works also for group planning my best friend's bachelor party.
The Way
I’ve been obsessed about AI Brain since 2016. Our human brains suck at some things like memory and are brilliant at others like creativity. We are also particularly bad at thinking we are all on the same page and then realising weeks later that we weren’t. Most leaders spend their days being the human diff tool, catching contradictions in hallway conversations and Slack threads. Repeating themselves 50 times. Now every company is spinning up hundreds or thousands of agents that drift faster than humans do, feeding each other their drift as context. Compounding rot.
After 10 years and one failed company in this space we are launching the solution.
The Launch
We thought about a celebrity launch. Margot Robbie in a bathtub explaining agents. But then we realised the same money gives the first 2,000 people free daily credits, every day, until we burn through that $1,000,000.
Sauna runs Claude, GPT-5, Gemini, GLM-5.1, DeepSeek, Kimi so you can budget yourself. The labs are racing to lock you so they can milk you in a year. We picked your side.
Onboarding
It’s live at app.sauna.ai We’ve preheated saunas based on a niche. Use the access codes in the comments to get a better experience.

LAUNCH OF SAUNA.AI in 12 HOURS. Get excited!!! freemium of the most powerful AI agent is coming, for the first 2000 people we will keep giving you free daily credits until we spend $1mm.
Sauna.ai is a multiplayer AI brain — an AI workspace that finally knows you, does the proactive work you shouldn't have to do yourself, and leaves you with the parts that need a human: taste, review, and responsibility for what gets sent. For teams it becomes hive mind with permissioning and delegated access.
i’m looking for ringo! 🥁
every great band needs someone with exceptional timing.
the beatles had bold ideas and powerful creative energy, yet what made their music feel effortless was rhythm. ringo brought a rare combination of product sense and technical control. he understood what the song needed in each moment and had the precision to deliver it consistently, shaping the emotional arc in a way that made the entire band sound tighter.
i’m looking for a design engineer with that same combination.
someone whose product sense guides decisions at every level, and whose technical depth allows those decisions to materialize in production. someone who understands pacing, proportion, motion, and detail instinctively, and can translate that instinct into a system that feels coherent and alive.
the difference between good and great products lives in thousands of small decisions. the right design engineer sees those decisions clearly and has the skill to shape them directly, turning architecture, interaction, and performance into instruments of clarity.
if you instinctively know when something is almost right but not quite, and you have the skill to close that gap yourself, i’d love to talk.
i'm building something new in consumer AI.
hiring for Drive, Taste, and Ambition. builders who think in first principles and ship like artists.
the goal: build a digital version of your mind. a living map of who you are that grows with you: your closest friends, the places you've lived, the moments that shaped you. then make it social.
if you'd enjoy the creative process of making an A24 film or perfecting a Michelin dish, obsessing over every detail until it's right, and want to bring that to consumer products, you'll thrive here.
looking for a designer and a design engineer. DMs open.

Can one build an Al agent that analyzes someone's personality? 🧐
We did it! Checkout twitter.wordware.ai/
Using our platform, we built an entire LLM backend with a structured generattion feature (JSON mode) and
quickly iterated with numerous prompts and LLMs available on Wordware.
This Al agent scrapes your tweets, analyzes them, and provides insights into your strengths, weaknesses, goals, love life, and even roasts you.
And we're launching this project on Product Hunt today (link in the first comment, pls pls pretty pls up vote)
It's free and open source, so you can build on top of it if you'd like.

Hi Friends,
Long ago, we built an internal tool on Wordware to structure our brainstorming ideas and for times when we talk to ourselves (yes, we do that a lot, especially our CEO @kozerafilip).
Then our use cases expanded, and so did our users as some friends saw us using it and asked for access. Lately, we built a front-end application for it and decided to share it with all of you (link in the comments).
We called it Audioscribe, and it is a WordApp—a Wordware application, one of many we plan to build and share with you and our community.
Just hit record, spell it all out, and we’ll turn it into a well-structured note.
It’s perfect to use for:
✍🏻 Project writeup: Transform scattered thoughts into coherent project plans. Speak your ideas, we'll structure them.
🧠 Brainstorming: Unleash your creativity without boundaries. Record your brainstorm, we'll organize the chaos.
📧 Email: Dictate emails on-the-go. We'll polish your words into professional correspondence.
💌 Personal message: Pour your heart out verbally. We'll craft it into a thoughtful, articulate message.
📖 Journal: Talk about your day's experiences. We'll transform them into reflective journal entries.
✅ Task planning: Voice your to-dos as they come. We'll organize them into an actionable task list.
👂🏼 Interview: Focus on the conversation. We'll turn your recording into structured interview notes.
📢 Social media post: Share your thoughts aloud. We'll shape them into engaging social media content.
💡Idea generation: Let your ideas flow freely. We'll capture and organize your creative sparks.
⚙️ and many more!

With all the wearable AI hype, we thought - why wait? We can already have a great, private solution - and using existing devices!
Coming to Deepen ( @deepen_app ) users soon - a key Apple Watch integration. 🥳
(sorry, but not sorry for the awkward video.)

Yesterday, we released a new update with some killer new features! Primarily, you can now use voice rather than text when talking to me!🎙️🎉
We're so excited about it, as it really feels like a completely different experience! hope you love it too!

It's kind of like having a therapist in your pocket.
Deepen uses AI to be a personalized, 24/7 therapy app

Weekly #buildinpublic update on @deepen_app !
First, if you haven't already - go and download Deepen -> thedeepen.app/ and give us ⭐️5 stars⭐️ :)
The update:
- We reached a very cool milestone: 100,000 words shared through the app. We are so happy to see people start getting value and come back day after day!
- We noticed we've got quite a few users from Spain, China, and Poland - so we worked on localizing the app for them, which will be out early next week!
- We kept improving our onboard process; now, when you first log in to the app, the user is prompted through a few choices, so the first session and the first impression show the value quicker
- Some cool new features: Kick off a new session from the previous one, have tailored made notifications, and more!
- We started talking with investors - doing better already, having nice progress there - getting beyond the intro call stage, with a ton of great feedback
- My sister laughed so hard at my boomer TikToks, but luckily she was willing to help me, and man! Her videos are getting 100x more views than mine, haha
What is coming next?
- Voice 👀, a feature that was requested by a few users and seemed to be valuable for retention and ease of use (people find it tedious to write)
- Some amazing Q&A UI to understand your sessions in a more engaging way - stay tuned!
- More more more! We've got so many things on our backlog, which is exciting and amazing
