ChatZima

ZIMA is the ultimate AI chat platform — one app, multiple world-class AI models. Choose from OpenAI's GPT-4o and the GPT-5 family, Anthropic's Claude Opus, Sonnet, and Haiku, and Google's Gemini, all from a clean, fast interface designed for how you actually work.

One App. Every Model.
Stop juggling subscriptions. ZIMA gives you access to leading AI models so you can pick the right one for every task — fast answers, deep research, creative writing, coding help, or just conversation.

Web Search Built In
Get real-time answers grounded in current information. ZIMA's AI search pulls from the live web so your responses are never out of date. And you can always see where answers come from — tap any response to open the sources sheet, browse the sites ZIMA referenced, and jump straight to the original page in your browser.

Extended Thinking
Enable deeper reasoning for complex tasks. When toggled on, supported models spend more time thinking through problems before responding — great for math, logic, coding, and nuanced questions. Look for the brain icon in the message bar. Available on select OpenAI, Anthropic, and Google models.

Image Generation
Create images directly in your conversations. Just ask the AI to generate an image and it will appear right in the chat. Powered by OpenAI and Google Gemini.

Video Generation
Bring your ideas to life in a whole new dimension. Create video from a prompt — describe what you want and watch ZIMA bring it to life. Use frame-to-frame interpolation to pick a starting and ending image and let ZIMA fill in a smooth, cinematic transition between them. Control aspect ratio for any format from square to widescreen to vertical, track progress with a smooth progress bar, and enjoy refined playback controls. Clear weekly limits keep you informed of your allowance, and if a generation ever fails, your usage credits are automatically refunded.

File Uploads
Bring your files into the conversation. Attach documents directly from the message bar and let ZIMA read, summarize, and answer questions about them — getting instant insights, explanations, and answers grounded in the content you share.

HTML Preview
Prototype websites and UI designs faster than ever. When the AI generates HTML code, you'll see a live, interactive preview right in the app.

Built for Speed
Streaming responses. Clean conversations. No clutter. ZIMA gets out of your way so you can focus on what matters.

Your Conversations, Organized
Every chat is saved and searchable. Rename, revisit, or pick up where you left off — synced across iOS and the web.
