Unium: All AI Models, One App

Use GPT, Claude and Gemini in one app - switch mid-conversation, pay only for what you use. No subscription, start for free, top up as little as $5 to unlock all models.

Unium puts today's leading AI models in one app. Switch between models in a single conversation, keep the chats you care about private, and pay only for what you actually use.

WHY UNIUM

One app, many models. Pick the right model for the task from a single picker, and switch mid-conversation without losing your thread. Use the best, most recent models from OpenAI's GPT, Anthropic's Claude, Google's Gemini series and many others.

Start free. Sign up and use the available free models right away. There is no subscription and no trial countdown.

Pay for what you use. Top up credits when you need paid models. Share credits with your family, friends, or team. Credits are simple prepaid packs, not a recurring bill, and they do not expire while your account is active.

Built to share, carefully. Invite specific people by email or link to a shared chat, project, or wallet. There is no random or anonymous matching. You can report or block anyone, and remove people from chats, projects or wallets you own.

Designed to stay out of your way. A quiet, readable interface with light and dark modes, fast model switching and image attachments.

PRIVACY

When you send a prompt to a cloud model, Unium tells you up front which providers may process it and asks for your consent the first time. Your conversations are never used to train models. You can delete your account, and all of its data, from inside the app at any time.

CREDITS AND PURCHASES

Unium is free to sign up and to use the available free models. Sending prompts to paid models uses credits, which you buy as one-time in-app purchases. There is no subscription.
