Onyx vs Zero Chat

Meet Onyx, the private AI assistant that runs entirely on your iPhone. Ask anything. Get instant answers. No account, no internet, nothing shared. A REAL AI ASSISTANT, THE ONE YOU ALREADY KNOW Ask questions, brainstorm ideas, write emails and messages, summarize long texts, translate languages, get explanations on any topic, fix your code, prepare for an interview, plan a trip. Onyx does everything you expect from a modern AI chat, with real conversations and follow-up questions. 100% PRIVATE, BY DESIGN Every question and answer stays on your iPhone. Nothing is sent to our servers, and your data is never used. Not even we can see what you ask. WORKS COMPLETELY OFFLINE Download an AI model once and use it anywhere. On a flight, in the subway, abroad with no signal. Onyx keeps working when other AI apps stop. HUNDREDS OF MODELS, ONE PERFECT FOR YOU Llama, Qwen, Gemma, and many more models, all free. Onyx analyzes your iPhone and highlights the ones that will run best on it, so you get the most capable assistant without guessing. FAST AND BEAUTIFUL Answers appear in real time as the AI writes. Clean formatting, elegant design, smooth from start to finish. No subscription. No data collection. Just you and a powerful AI that respects you. Download Onyx and take back control of your AI.

Zero Chat brings GPT, Claude, Gemini, and more AI models into one app. An active subscription is required. Choose the right model for the task. Browse models by provider, compare their strengths and token prices, or search for a favorite. Switch models in the same conversation when you want a different perspective. Plan a trip, draft a message, explore an idea, or work through a problem. Add photos from your camera or gallery, use web search, and set custom instructions. Your chats stay together across supported devices. A monthly auto-renewable subscription enables Zero Chat's AI features. Apple charges your Apple ID when you confirm the purchase. The subscription renews automatically unless you cancel at least 24 hours before the current period ends.
