Usage

• •Configure your server URL in the app: LiteLLM http://your-server:4000, or direct Ollama http://your-server:11434/v1 (OpenClient appends API paths without adding/removing /v1).
• •Optional server API key is stored in Keychain and sent as a Bearer token.
• •Use MCP tools from servers configured on your LiteLLM backend — discover, enable, and execute them from the chat input bar.
• •Self-host with Docker Compose via the Ollama.md / LiteLLM.md guides; Ollama through LiteLLM unlocks multi-provider support and cost tracking.

Key features

• ✓Streaming responses with Markdown/code blocks; collapsible Thinking block; multimodal (photos, camera, PDF); drag-and-drop files; TTS/STT.
• ✓MCP tool support, agentic tool-calling loop, web search via your server's providers, image generation via LiteLLM image models.
• ✓Conversation management: branch, edit/regenerate, favorites/pins/tags, media gallery, deep links (openclient://chat?text=…), full JSON backup/restore, Private Chat.
• ✓Apple native: Shortcuts + Siri actions, Control Center toggle, seven home-screen widgets, menu-bar companion on macOS, iCloud sync.
• ✓Per-conversation system prompts/params, prompt-template library, memory, 10 app languages; AGPL-3.0.

Best for

Users who want a modern native Apple chat client that talks only to their own LiteLLM/Ollama server and consumes MCP tools configured there — no hosted provider lock-in.

Caveats

• ⚠OpenClient is an MCP CLIENT, not a server — it needs a running LiteLLM/Ollama/OpenAI-compatible backend to be useful.
• ⚠MCP support depends on servers configured on the LiteLLM backend; direct Ollama needs OpenAI-compatible /v1 endpoints.
• ⚠iOS 26+/macOS 26+ and (for source builds) Xcode 26+; AGPL-3.0 license.
• ⚠In-app feedback (Votice) requires the VOTICE_* secrets; empty placeholders are enough to build.
