Build an AI Product Description Generator for E-commerce (Cheap API)

Build an AI product description generator

Writing and localizing product copy is a grind for any online store, especially cross-border. An AI
generator turns specs into persuasive, on-brand descriptions — in any language. GPT-5.5 via APIVAI
is a great fit: fast, fluent, multilingual, and cheap enough to run over a whole catalog.

Generate a description

from openai import OpenAI
ai = OpenAI(api_key="YOUR_APIVAI_API_KEY", base_url="https://api.apivai.com/v1")

def describe(product, lang="English", tone="persuasive but honest"):
    r = ai.chat.completions.create(model="gpt-5.5", messages=[
        {"role": "system", "content": f"You write {tone} e-commerce product descriptions in {lang}. Keep specs accurate. Output a title, 2-3 sentence description, and 3 bullet highlights."},
        {"role": "user", "content": str(product)}])
    return r.choices[0].message.content

print(describe({"name": "Travel backpack", "material": "water-resistant nylon", "capacity": "35L", "features": ["laptop sleeve", "USB port"]}, lang="Spanish"))

Localize for new markets

Loop your catalog and generate per-market versions (Spanish, English, Portuguese, Arabic…). Same
specs in, native-sounding copy out — no separate translation step.

Tips

• Include a glossary of brand/industry terms in the system prompt to lock terminology.
• Keep specs in the input so the model doesn't invent details.
• For huge catalogs, run with light concurrency and back off on rate limits.
• Keep a human review pass for accuracy on key SKUs.
