Unium is the AI app you share - chats, costs, everything.
- Chat together. Invite your partner, a friend, or your whole team into the same AI conversation. Everyone sees the same chat and everyone can join in. Perfect for making decisions together, planning as a family, or working through something as a couple.
- Share one balance. Instead of everyone paying for their own subscription, top up one wallet and share it with the people you choose. Everyone keeps their own private account — no more sharing passwords or seeing each other's chats.
- Pay only for what you use. No monthly subscription. Most people never use a subscription to the fullest but pay the full price anyway. With Unium, you top up when you want, your balance lasts up to a year, and each message costs only what it actually costs.
- Use the best AI, always. GPT, Claude, Gemini, DeepSeek and more — all in one app, always the latest versions. You can even switch models in the middle of a conversation and keep everything you've discussed. Web search and image generation work with all of them.
- Group chats into projects. Keep related conversations together so they share the same context — and the same people.
- Your chats stay yours. We never use your conversations to train AI models.
Getting started is free: sign up and try the app with our free models (availability may vary — paid models are always available). Top up whenever you're ready for more.
