Getting started
Make yourself at home.
Install, sign in, and make Baymax yours.
1. Start on Windows
Get the Windows x64 installer from Downloads. Install Baymax and open the app. Release details and the checksum are listed alongside the download.
2. Say hello
Continue with Google in the app, then choose your unique username. Pick a plan in Plans & Membership. The website does not create your account or handle payment.
3. Bring your AI keys
Add your own Groq API key for chat. Gemini Live requires an eligible Pro or Duo plan and your own Gemini key. Provider availability, limits and usage charges belong to your AI provider. Never send your keys to support.
4. Make it yours
Open Companion settings and explore the Wardrobe. Choose from twenty original companions and customise the colour. Your preview on this website is not saved into the app.
5. Find your person
Search for your partner’s username and send an invitation in the app. They review and accept it. Duo covers two assigned seats under one payment; buying a seat does not automatically give access to another person’s data or PC.
6. Share a little more
Use partner chat and shared tasks once your shared backend is connected. Baymax Cloud and Listen Together require eligible paid access for both people. Free partner sync needs a personal Supabase project and technical setup. Automatic custom-database setup and switching are still being validated.
Request remote PC access only when you need to help. The other person must accept before the session starts. Keep both apps open and connected for shared features.
Start small
Try local tasks, solo music and Groq chat first. You can explore these without setting up a personal database. Music streaming and AI requests need an internet connection.
