AI Descriptions is a Shopify app that uses OpenAI's GPT-4o-mini to write product descriptions, SEO titles, and meta descriptions directly inside the Shopify admin. Prompts support 5 tones (Professional, Casual, Playful, Luxury, Minimalist) and 3 length options (Short, Medium, Long).

Includes a custom OpenAI client with exponential backoff with jitter (4 retries, 90s total budget), safe error message sanitization, per-generation cost tracking, and one-click apply to Shopify via GraphQL Admin API.
