Omni AI is a free Android application that brings together several leading large‑language‑model services—ChatGPT, Google Gemini, Anthropic Claude, Grok and others—into a single chat interface. The app lets you start a conversation, ask questions, or request creative work without switching between different web pages or apps.
When you launch Omni AI, you are presented with a clean chat window. A toolbar lets you select the underlying model for the current session. Text is sent to the chosen provider via its official API; the response is displayed instantly. For image‑based math, the app first runs an on‑device OCR step, then forwards the extracted expression to a GPT‑4o endpoint that is capable of reasoning about visual input. File analysis follows a similar pattern: the file is read locally, its content is sent to the model, and the returned summary or insight appears in the chat.
Download the APK from the Appitika page or install directly from Google Play. The app requires Android 6.0 (Marshmallow) or newer and an active internet connection for all AI calls. After installation, you will be asked to provide an API key for OpenAI or other services; the app also offers a limited free quota for casual use.
Omni AI runs on smartphones and tablets that support the standard Android runtime. It is optimized for both portrait and landscape orientations and works on devices with at least 2 GB of RAM. No root access is needed.
The core app is free, but access to premium models may require you to supply your own API key or purchase additional credits.
No. The AI processing happens on remote servers, so an internet connection is mandatory.
All requests are encrypted, and the app does not retain personal data beyond the active session unless you choose to export it.
