Mocca is a native AI chat client for iPhone. Connect your preferred model provider, create your own assistants, and chat, write, and explore ideas in one simple space. Make it your own • Connect compatible model providers with your own API keys • Create one-to-one conversations and group chats with multiple assistants • Share images and files, with support for Markdown, syntax-highlighted code, math, and tables • Use optional web search, speech playback, and MCP tools • Customize assistant prompts, recent memory, and worldbooks • Keep track of background generation with Live Activities • Store chats locally on your device, with import, export, and backup options Mocca is a client, not a model service. You will need a compatible third-party provider and your own API key. Provider availability, supported features, and usage charges depend on the service you choose. You can also support development with optional tips. Tips do not unlock additional chat features and do not renew automatically. Your first purchase at a given tier includes a permanent commemorative cosmetic; repeat purchases at that tier do not add new cosmetics.

Connect your own DeepSeek or Chat Completions-compatible service and manage conversations on iPhone and Mac. - Read streaming responses and use reasoning controls when supported by your model. - Search saved conversations, edit questions, and explore alternative response branches. - Attach images, PDFs, text files, and DOCX documents for supported models. - Export a conversation as JSON. Markdown export is also available on Mac. - Use native Mac windows, keyboard controls, and file drag and drop. The app is free to download. Live AI chat requires your own API key from a third-party provider. Provider usage charges may apply and are not included with this app. Model capabilities vary. Chat content and attachments are sent to your selected provider. History is stored locally and API keys are stored in the system Keychain. History and keys do not automatically sync between iPhone and Mac. DS-Classic is an independent client, not an official app of DeepSeek or any other AI provider.
