Omni AI aggregates 20+ models including GPT-5, Grok, Gemini in one free app

Omni AI is a free app that brings together over 20 leading AI models from OpenAI, Anthropic, xAI, Google, DeepSeek, Mistral, Meta, and others. Instead of paying for multiple subscriptions—ChatGPT, Gemini, Grok, Claude—users get all of them in one place. The app includes GPT-5-Nano, GPT-5.1, Claude Haiku 4.5, Claude Sonnet 4.5, Grok 4.1 Reasoning, Grok 4.1 Fast, Gemini 3, DeepSeek V3.1, DeepSeek R1, Mistral Large 3, Perplexity Sonar, Seed 1.8, Llama 4 Scout, Qwen 3 VL, and GLM-4.7 FlashX. Each model displays its strengths (e.g., GPT-5 for writing, DeepSeek R1 for math/reasoning, Gemini 3 for multimodal understanding) so users can pick the best tool for each task. The app also features real-time web search that retrieves live results and summarizes them with source citations, and AI image generation supporting styles like photorealistic, artistic, cartoon, 3D render, and watercolor. All conversations and generated content sync across devices.

With 175 million messages already sent and a 4.5-star rating, Omni AI is gaining traction among professionals who need quick access to diverse AI capabilities. The app eliminates the friction of switching between separate apps and paying for multiple premium subscriptions. It is especially useful for coders, researchers, writers, and marketers who want to compare model outputs or leverage specialized models for different tasks. Available on both iOS and Android, Omni AI positions itself as a Swiss Army knife for AI—combining chat, search, and creation in one free, cross-device tool. For tech-savvy professionals tired of managing multiple AI accounts, this consolidation could be a significant productivity boost.
