Omni AI

Omni AI puts 22 leading AI models into one chat: GPT-5.6, Claude Opus 5 and Sonnet 5, Gemini 3.6 Flash, Grok 4.5, DeepSeek V4, Kimi K3, Mistral Medium 3.5, Llama 4 Maverick, Perplexity Sonar Pro and more. Switch models in the middle of a conversation and the new model sees the full thread, so you can check one answer against another without copy-pasting. Beyond chat: AI image generation, Google Veo 3.1 video generation, web search with citations, file and image input, and one account synced across iOS, Android and the web. Free tier with daily limits; Pro is $9.99/month or $59.99/year instead of paying for four separate AI subscriptions.
