Project description:
"Want to build a web application where users can design their own T‑shirts through a chat‑based interface and complete their purchase in a single flow. The site should also include a public gallery of user‑created designs and integrate with an existing WooCommerce store for order fulfillment.

Core Features & Flow

Conversation‑Based Designer

A chat interface where users enter a text prompt (and optionally upload an image) describing the artwork they want. They also select an art style and their preferred music genre.

Before generating any design, the user pays a ₹50 deposit. Once payment is received, trigger an AI (e.g., ChatGPT or other image generator) to produce the artwork.

Display the generated image; allow the user to make simple edits (crop, resize, filters). When the user approves the image, proceed to product customization.

Product Customization

T‑shirt Style Selection: Offer Round Neck (₹399), Full Sleeve (₹499), and Hoodie (₹799) options.

Colour & Size: Prompt the user to choose a colour (e.g. black, white, blue, red) and size (S/M/L/XL).

Placement & Print Size: Provide a visual editor where the user places and resizes the design on the front, back, or both sides of the garment. Available print sizes: A6 (₹150), A5 (₹175), A4 (₹199), A3 (₹249). The printing price is per side.

Pricing: Calculate the total as the base price of the garment plus the printing price for each selected side. Show the running total dynamically before checkout.

Checkout & Order Management

Allow customers to complete payment for the final T‑shirt with their chosen print and garment size.

Save order details, including the final design and placement data, to your WooCommerce store. For each order, create a corresponding folder via FTP named after the order number containing:

The final design image file.

A JSON file with all order details (product style, colour, size, print size, placement, total price, and user information).

Order History

Once logged in, users should see a list of their past orders, with order status and total cost, and have the option to reorder.

Public Design Gallery

Display all user‑created designs publicly. Each design card shows a preview image and price.

Visitors can choose to either purchase that design (starting from the style selection step) or reuse its prompt to generate a new variation. Clicking “Use Prompt” should prefill the chat with the original text description and show the preview in the conversation.

Authentication

Provide a simple login system via Gmail to give users access to their order history and allow them to save designs. Show “Login” when not authenticated and the user’s name with “My Orders” and “Logout” when logged in.

Additional Details

Base garment prices: ₹399 for Round Neck, ₹499 for Full Sleeve, ₹799 for Hoodies.

Printing prices are the same for front and back; see the costs per print size above.

Use WooCommerce to handle payments and record orders; integrate via its API.

Save final design files via FTP to a structured folder system for production use.

The overall user experience should be polished, modern and friendly, with a clear step‑by‑step flow from design to checkout.

The freelancer’s task is to design and develop the entire application, including the chat‑based designer, customization flows, public gallery, login system, and WooCommerce/FTP integration with CHATGPT API and its prompt." (client-provided description)
