So you can access your journals and diary from any web browser and other devices. Penzu is constantly being updated and improved so that the writing experience is effortless and reliable.

Arca AI Chat is a private, flexible client for any OpenAI-compatible language model service. Your conversations go directly from your device to the server you choose — nowhere else. No accounts. No data collection. No conversation logging on our end. Arca never sees your messages, your API key, or who you're talking to. Your chat history is stored only on your device, under your control. Connect to any OpenAI-compatible endpoint — OpenAI, Groq, your own local Ollama instance, or any self-hosted inference server. You own the entire stack. Key Features: • True privacy: messages go directly to your configured endpoint, never through Arca's servers • Chat history stored locally on your device only • API key secured in your device's encrypted Keychain — never transmitted to us • Connect to any OpenAI-compatible LLM endpoint (OpenAI, Groq, Ollama, and more) • Apple Watch companion app for on-the-go conversations • Clean, focused interface for productive AI conversations Whether you're running your own local inference server or using a third-party provider, Arca gives you a unified, private interface — and nothing more.
