Helium 10

Helium 10 is one of the best known tools for people who sell on Amazon. It also supports Walmart and TikTok Shop. The suite covers product research, keyword research, listing optimization, advertising, and inventory, so a seller can run most of the day-to-day work from one account.

The AI layer includes Helium Agent, an assistant that completes tasks inside your dashboard, and Listing Builder, which generates product listings from your inputs. Helium MCP connects Helium 10 data to assistants such as Claude and ChatGPT, so you can ask questions about your catalog and market from the chat window you already use.

There is a free tier for getting started and paid plans that unlock the full tool set. It is aimed at advanced sellers, brands, and agencies, and the amount of tooling can feel heavy for someone selling a handful of products. Jungle Scout is the most common alternative. Helium 10 is a strong choice when marketplace selling is a main business.
