If you are looking for a ChatGPT alternative, the real question is not "which single model is best?" — it is "why settle for one model at all?" Omni AI gives you GPT-5, Claude, Gemini, Grok, DeepSeek and 20+ other leading AI models in one app, so you can pick the best tool for every task instead of paying for separate subscriptions.
It is free to download on iOS and Android, includes AI image and video generation, and lets you compare answers from different models side by side. Here is why people switch.
Why use a ChatGPT alternative?
ChatGPT is excellent, but it has limits: you are locked into OpenAI's models, the best models sit behind a paid plan, and you need separate apps for Gemini, Claude or Grok. A multi-model app removes those constraints:
- No vendor lock-in. Use OpenAI, Google, Anthropic, Meta and DeepSeek models from one place.
- Best model per task. GPT-5 for structured analysis, Claude for nuanced writing, Gemini for research, DeepSeek R1 for coding.
- One price, every model. No need to stack ChatGPT Plus, Gemini Advanced and Claude Pro subscriptions.
- More than chat. Generate images, create videos and run AI web search in the same app.

You can switch between any of them in a single conversation, ask the same question to two models, and compare their answers — ideal for important decisions where one perspective is not enough.
Is Omni AI made by OpenAI or Google?
No. Omni AI is an independent app built by Bridge Softwares. It is not ChatGPT, and it is not Google's Gemini. Some people search for "Gemini Omni" or assume it is an official OpenAI product — it is neither. Omni AI is a separate app that lets you use models from OpenAI, Google, Anthropic and others together, so you get the strengths of each without choosing a side.
