Commerce Content Engine

Turn verified product facts into a complete, editable commerce copy bundle.

• Write a product page with FAQ, ad copy, hashtags, a shorts script and thumbnail text.
• Check claims against your facts with Fact Guard, or compare short ads in a tournament.
• Export Markdown or JSON; calculate margin from your own prices and costs.

Quick start (Node 18+, no dependencies):

npm test
node cli.mjs --demo
NEBIUS_API_KEY="$NEBIUS_API_KEY" node cli.mjs --provider nebius --name "Steel cup" --info "500 ml; stainless steel; removable lid; hand wash" --lang English

Set NEBIUS_API_KEY in your environment for live generation. LLM_API_KEY, LLM_BASE_URL and LLM_MODEL support compatible providers. --demo uses labeled offline fixtures. node scripts/serve.mjs starts the web app on the hosted branch. GitHub Pages sends your own key directly from the browser to your chosen provider.

Nemotron on Nebius

• Nebius copy uses strict JSON Schema and original Korean/English examples. Length, claim, completeness and caveat checks trigger one model repair; unknowns stay in seller listing checks.
• On the hosted branch, DeepSeek V4.1 Flash writes and Nemotron Super reviews factual claims; the tournament gates ads before simulated buyer comparisons.
• Built during the hackathon: CLI, browser editor, Fact Guard, tournament, hosted demo and real-response regression checks. AI review uses seller facts and still needs editorial judgment.
