Cherry Studio is an AI workspace for iPhone and iPad, bringing together multi-model conversations, agents, image creation, and tool connections. Connect your chosen models Configure model services and service keys, manage multiple models in the same app, and choose suitable capabilities for different tasks. Model availability and the ability to process text, images, and files depend on the services you configure. Let conversations serve work and creativity Have conversations about writing, learning, organizing materials, and everyday questions. Read responses as they are generated, and supplement the context with images and text attachments. Create your own agents Set names, instructions, default models, and tools for different purposes, and manage conversations for different projects separately. From ideas to images Connect models that support image generation, start creating from text descriptions or existing images, and view and manage your drawing history. Connect tools as needed Configure search services, plugins, or MCP tool services to provide agents with web search and external tool capabilities. These features depend on service configuration and permissions. After authorization, calendar and reminder tools can also be used. Organize and share results Manage attachments and generated files, preview documents, and export supported conversation content as Markdown, HTML, or images. You can also pair with the Cherry Studio desktop app to import supported model service configurations. Apple Health health and exercise analysis On supported iPhones, grant agents read-only access to steps, walking and running distance, active energy, heart rate, resting heart rate, heart rate variability, sleep, and workout records in Apple Health. Before each tool read, you can review the scope and the AI service receiving the data, and choose to allow or deny it. The app does not modify health records. Analysis results are saved in conversations and can be deleted with them; AI answers do not constitute medical advice, diagnosis, or treatment. Before use The app is free to download. Model and third-party tool services may require separate accounts or service keys, and the respective providers may charge fees. Chat history is saved on your device. When you use models or online tools, relevant inputs are sent from your device to the services you configure; providers handle data according to their own policies. The app also has error diagnostics and operational statistics features. See the privacy policy for the specific scope of collection. AI-generated content may contain errors. Please verify important information. Built for iPhone Duo and larger screens Enjoy fold layouts tailored to iPhone Duo, preview files beside local chats, and expand documents for focused reading.
