# Gemini Pro/Ultra Subscription

> Use your existing Gemini Pro/Ultra subscription in EnConvo

## Overview

If you already have a Google One AI Premium subscription or Gemini Pro/Ultra, you can use your existing account directly in EnConvo without needing a separate API key.

<Note>
  This is different from using the Google AI API. Here you use your existing Gemini subscription credentials.
