DeepSeek

What it does

DeepSeek's chat assistant runs models that sit close to the frontier on reasoning and code, and it is free to use. For China-based export teams it is the easiest high-quality assistant to reach without a foreign card.

The web app handles document upload and deep-research style tasks. Bilingual CN-EN output is a particular strength, which matters when polishing listings and buyer replies.
