## What is Unium?

Unium is the AI that helps you solve problems together. You invite your partner or friend into the chat and let AI mediate, suggest ideas and research information. So you no longer need to share screenshots, links or retell what AI told you - now AI can talk to everyone and everyone can talk to AI in the same place.

That's perfect for planning trips, navigating relationships, resolving arguments and more. It's always there to hear all sides, suggest compromise, research a fact or otherwise help all of you to move forward.

Besides that, you can still have private chats with AI, without compromising your privacy.

Getting started is free. Once you need more usage, you can buy a subscription and share it with everyone automatically.

Free users get access to our automatically chosen model. Paid users can choose models for themselves, including GPT 5.6, Claude Opus 5, Gemini 3.1 Pro and others.
