Everyday writing, emails, brainstorming and step-by-step reasoning.

Questions

What exactly do I get?

One chat app with seven models from four companies: GPT-6 Luna and GPT-6.1 Sol (OpenAI), Claude Haiku 5.5 and Claude Sonnet 5.5 (Anthropic), Gemini 3.8 Flash and Gemini 4 Argon (Google), and Grok 4.7 (xAI). You can switch models at any point in a conversation.

Is this the same as paying for ChatGPT Plus, Claude Pro and the others?

You get the same model families, accessed through each company's official API, inside our app. Features that only exist in each company's own app, such as voice mode, image generation, custom GPTs or projects, are not included. If you mainly type questions and read answers, you get what you need for a fraction of the cost.

What does “unlimited” mean?

Messages to the fast models (GPT-6 Luna, Claude Haiku 5.5, Gemini 3.8 Flash) are unlimited for normal personal use. Premium models (GPT-6.1 Sol, Claude Sonnet 5.5, Gemini 4 Argon, Grok 4.7) include 300 messages a month, which resets on the 1st. Automated or shared use isn't allowed. See the fair-use section of our Terms.

Do I need a card for the free trial?

No. Sign in with Google or Microsoft and start chatting. The trial lasts 14 days with 20 messages a day on any model. When it ends, nothing is charged. You can subscribe if you want to keep going.

How is my privacy protected?

Before a message leaves our servers, we replace email addresses, phone numbers, Social Security numbers, card numbers, IP addresses, passwords and API keys with placeholders. The AI never sees them, and they're put back into the reply on your screen only. We route requests only to providers that don't train on or retain your prompts, and we don't store your conversations.

Are my chats saved?

No. Conversations live in your browser tab and disappear when you start a new chat or close the tab. We only record usage data, such as which model you used and when, to apply plan limits.

Can I cancel anytime?

Yes. Cancel from your account page in two clicks. You keep access until the end of the period you've paid for, and you won't be charged again.
