Add AI Product Assistant (ChatGPT API) to Shopify Website – No Chatbot, Just Simple Text Box

Description:
We want to add a simple AI-powered product assistant to our Shopify website https://creativeautomation.ae.

This will NOT be a chatbot – we only need a clean text input box where users can type questions like:
• “I need a 24V DC solenoid valve, 1/2 inch, 16 bar”
• “Suggest alternatives for ABB AF116-30-11-11”
• “Find FESTO 575630 or a replacement”

The AI should return answers using OpenAI’s ChatGPT API (GPT-3.5 or GPT-4) and show the response directly below the box.

Required Features:
Input box with submit button (titled “Ask Our AI Assistant”)
Send user input to ChatGPT API
Show formatted response under the input
Match our website design (light, professional)
Works on desktop and mobile
No chatbot UI – just a clean Q&A format
Optional: Log queries for analytics (Google Sheets or simple backend)
