It verifies your User ID to ensure only you can use the credits.\n2. **Analyze:** **Gemini Vision** looks at the photo to understand the product, context, and lighting.\n3. **Brainstorm:** An **AI Agent** takes the vision analysis and generates a creative ad campaign concept, including a marketing rationale and a specific image generation prompt.\n4. **Generate:** The workflow uses **Gemini's Image Generation** capabilities to create a visual mock-up of the ad concept.\n5. **Deliver:** The resulting ad creative is sent back to you instantly on Telegram.\n\n### Setup steps\n1. **Telegram:** Create a bot via BotFather. Get the Token and your personal User ID (via @userinfobot).\n2. **Config:** Open the **CONFIG** node (Green) and enter your `authorized_user_id`.\n3. **Credentials:** \n - Add your **Telegram Bot Token** in the Trigger and Sender nodes.\n - Add your **Google Gemini API Key** in the Gemini nodes.\n4. **Activate:** toggle the workflow to 'Active' and send your bot a picture!"
