Grafychat is a privacy-first AI chat client that provides a visual canvas to organize conversations with multiple AI models. It supports OpenAI, Google AI, and local Ollama models, allowing you to use your own API keys without sign-up. All data stays on your device. The canvas lets you connect ideas and manage chats non-linearly. Features include customizable prompts, full-text search, editable markdown chats, code highlighting, and keyboard shortcuts. A free tier offers limited contexts and chats; a one-time purchase unlocks unlimited use. Ideal for students, privacy-conscious users, and anyone seeking a flexible, non-linear AI interface.
