## What is Caverno?

Caverno is a powerful chat client for locally-hosted LLMs. Connect to Ollama, LM Studio, vLLM, or any OpenAI-compatible API endpoint and start chatting — no cloud required.

KEY FEATURES

• Any OpenAI-Compatible Server
Connect to your own LLM running on localhost or your local network. Supports any endpoint that speaks the OpenAI API format.

• Tool Calling (MCP Protocol)
Extend your AI with real-time tools — web search, calculator, code execution, and more. Caverno uses the Model Context Protocol to let your LLM take actions.

• Session Memory
Your assistant remembers your preferences, constraints, and context across conversations. Memory is stored locally and fully under your control.

• Voice In & Out
Speak your messages and have responses read aloud. Configurable speech rate and auto-read options.

• Image Attachments
Attach photos from your library to include visual context in your conversations.

• Multiple Conversations
Create, switch, and manage separate chat threads. All conversations are persisted locally.

• Assistant Modes
Switch between General and Coding modes for different response styles tailored to your task.

• Privacy First
No account required. No data sent to third parties. All conversations and memory stay on your device — the only network connection is to the server you configure.

GETTING STARTED
1. Install an OpenAI-compatible LLM server (Ollama, LM Studio, etc.)
2. Open Caverno and go to Settings
3. Enter your server URL and select a model
4. Start chatting!

Caverno is designed for developers, AI enthusiasts, and anyone who wants full control over their AI assistant.
