Cedar is a flexible AI workspace for iPhone and iPad that lets you choose the right model for the job. Use Apple Intelligence for on-device experiences, connect to your own Ollama server for self-hosted open-source models, or work with cloud models from Claude, OpenAI, and Gemini, all from one app. Switch between providers and models per conversation, fine-tune behavior with conversation-specific settings, attach files in supported workflows, generate images with supported OpenAI and Gemini models, and view web citations when supported responses include them. Cedar also brings Claude Managed Agents into the app, giving you a more powerful way to handle multi-step work and specialized assistants in one place. You stay in control of how each conversation is handled. Keep work on-device with Apple Intelligence, route it through your own Ollama setup, or use connected providers when you want access to their hosted models and tools. Cedar is designed to make those choices clear and practical, while securely storing API keys in Keychain. Whether you want private on-device help, self-hosted open-source models, or access to leading cloud AI systems, Cedar makes it easy to move between them without changing apps or workflows. It’s built for people who want one place to explore, compare, and work with modern AI on their own terms.
