Enchanted

Enchanted is an open-source app for macOS, iOS and visionOS that provides a chat interface for privately hosted language models. It works with Ollama, so models such as Llama 2, Mistral and Vicuna run on a server you control while the app supplies the polished front end. The README describes it as essentially a ChatGPT-style interface that connects to your own models.

The feature list includes conversation history stored on the device, markdown rendering for tables, lists and code blocks, voice prompts, read-aloud text to speech, image attachments, a configurable system prompt, editing messages or resubmitting them with a different model, deleting conversations, light and dark modes and a Spotlight-style panel on macOS. The project notes that all features work offline against your own server.

You need to run your own Ollama server, version 0.1.14 or later, and point the app at it, either publicly or through your own network setup. The app is distributed through the App Store and licensed under Apache-2.0. The README mentions that a successor project called Jaz is the new iteration of this one.
