Only for iPhone

Free · Designed for iPhone. Not verified for macOS.

iPhone

Bring your own API key to chat with AI, manage conversations and reasoning settings, explore branches, attach files, and export chats as JSON. 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.
