The AI you need at the price you want.
Write, research, create and get work done with hundreds of AI models in one app.
CHOOSE HOW YOU RUN YOUR AI
Connect OpenRouter to access 300+ models, including OpenAI's GPT models, Claude, Gemini, Llama and Mistral. Pay for what you use, with no markup from NanthAI.
Or connect Codex and Pi on your Mac with NanthAI Runtime and Pro. Use your existing provider accounts or local models configured through Pi, and work from your iPhone or iPad.
PUT YOUR AI MODELS TO WORK TOGETHER
Bring models and Personas into the same conversation. Have one draft, another critique, and others build on the ideas. Cloud and Mac participants can collaborate in one thread.
EXPLORE EVERY DIRECTION
Branch from any message to try another approach without losing the original. Organise chats into folders and continue across your devices.
YOUR MODELS, YOUR SETTINGS
Filter models by capability and price. Adjust creativity, response length and reasoning effort where supported.
