lemon cha

A browser extension chat window for supported LLM APIs and local Ollama models.

Full description lemon cha is a dedicated browser chat workspace for writing, translation, code review, troubleshooting, and everyday AI-assisted work. It keeps the experience calm and lightweight while giving each chat its own remembered mode, so normal conversations and translation sessions stay easy to distinguish. You can: Connect your own OpenAI-compatible API. Use local Ollama models. Save model-specific API, model name, temperature, token limit, and system prompt settings. Launch reusable workflows with prompt presets. Start a dedicated translation chat without interrupting the current conversation. Organize conversation history with folders, rename chats, and export Markdown. Configure interface language, default answer language, and default translation target language. By default, the interface follows the browser language when available, with English as the fallback. lemon cha does not provide its own cloud model service. Your requests are sent only to the model endpoint you configure or to your local Ollama server.
