Private AI chat app for iOS with local and cloud models

3sparks Chat is a flexible AI chat application designed for iOS, iPadOS, and VisionOS that allows users to run advanced language models locally on their device or connect to cloud APIs. It supports private on-device GGUF models, integration with LM Studio, Ollama servers, and OpenAI-compatible APIs, enabling private, fast, and versatile AI interactions including vision capabilities and document handling. The app also features an AI keyboard extension for rewriting, summarizing, and translating text across apps.
