Omni AI puts the best AI models in one app. Instead of juggling separate subscriptions and apps for ChatGPT, Claude, Gemini, DeepSeek, Grok and more, you get them all in a single chat interface on iOS and Android, and can switch models mid-conversation to compare answers or pick the one that suits the task.
It's built for people who use AI every day — students, writers, developers, professionals — and want one place to chat, write, brainstorm, summarize documents, analyze images and get answers, without paying for five different tools.
What makes it good: a clean, fast native mobile experience (built with Flutter), access to the latest frontier models as soon as they ship, chat history that syncs across devices, and a free tier so you can try it before subscribing. Over 20,000 downloads with a 4.2-star rating.
