Helium 10 has been the default answer to 'what tools do I need to sell on Amazon' for years, and the 2026 version makes the case stronger and the bill bigger at the same time. The suite now covers the whole seller lifecycle - finding a product, writing the listing, running the ads, tracking profit, managing inventory, even clawing back FBA fee errors - and it has pushed into Walmart and TikTok Shop. It also added an AI agent and MCP access on the top tiers, which matters if you wire your selling data into custom dashboards or agents.
The tool that made the name is still the Chrome Extension. Xray sits over any Amazon search results page and pulls estimated monthly sales, revenue, review counts and price history for every listing on the page. Black Box filters the whole catalog by demand and competition thresholds. Cerebro does reverse ASIN lookup - paste in a competitor product and get every keyword it ranks for. These three tools are why people pay, and in 2026 everything else is layered around them.
Pricing: the real math
Verified from helium10.com (Nov 2026). The free plan is permanent, not a trial: 5 Black Box uses, 10 Xray runs, Cerebro twice a day, 20 tracked keywords, and there is a separate 7-day free trial of the paid tiers with no card. Starter is $29/mo billed annually ($39 monthly) and is mostly the extension plus training plus limited tool usage - fine for validating an idea, too small to run a business. Platinum is $79/mo annual ($99 monthly): 250 Cerebro and Magnet lookups a month, 500 tracked keywords, 2 seller accounts, 40 SKUs of inventory management, AI-powered ads, and the Managed Refund Service. Diamond is $229/mo annual ($279 monthly): 500 lookups, 2,500 keywords, 5 users, rules-based ad automation with dayparting, TikTok Shop tools, and the influencer database. Enterprise is custom, with third-party sources listing around $1,499/mo as the entry point.
Two costs hide in plain sight. First, monthly billing runs 30-40% above the advertised annual numbers, so budget against $99, not $79. Second, the Managed Refund Service keeps a cut - 15% on Platinum, 10% on Diamond - of everything it recovers. It usually still nets you money, but 'included' is doing some marketing work in that sentence.
How people actually make money with it
The obvious path is selling your own product: Xray and Black Box find under-served niches, the profit calculator stress-tests margins against FBA fees, and Cerebro hands you the keyword list before you write a word of copy. But the less obvious path is selling the research itself. Product research reports built on Xray data go for $500-$2,000 in seller communities and freelance platforms. Listing optimization - Cerebro keywords plus the AI Listing Builder - prices at $150-$500 per listing, and PPC management retainers start around $500/mo. A single agency client covers a Diamond subscription with the ad-automation features left over. The TikTok Shop converter is quietly becoming a service line of its own: brands want their Amazon catalogs ported over, and the tool compresses days of work into an afternoon.
Where it disappoints
The sales estimates deserve permanent suspicion. Xray extrapolates from best-seller rank and review velocity, and in young niches or seasonal categories the numbers can be off by a multiple. Sellers who treat the estimates as ground truth instead of a prior are the ones who end up with 500 units of a product nobody wants. The usage caps are the other friction: 250 Cerebro lookups a month on Platinum evaporates if you research in batches, and Helium 10 knows the caps are the reason Diamond exists.
The interface has also grown heavy. What used to be a focused research suite is now a platform with an agent, academies, refund workflows, inventory, and multi-marketplace modules. Expect weeks, not hours, to learn it properly - and expect some modules to sit unused no matter which plan you buy.
Against the alternatives
Jungle Scout is the name most often weighed against it, and the honest comparison is that Jungle Scout is friendlier for absolute beginners while Helium 10's Cerebro and extension data are deeper for anyone past week two. Smart Scout, AMZScout and Viral Launch undercut on price but none of them cover ads, operations and refunds in one login, which is where the bundle economics actually work out. The newer threat is Amazon's own tooling: Seller Central's Search Terms report and Brand Analytics are free and genuinely useful, and they cover perhaps 60% of what casual researchers need. What they do not cover is competitor revenue estimation, listing-grade keyword intelligence, or anything outside Amazon's walls - which is precisely the slice Helium 10 monetizes.
Who should skip it
If your business is not Amazon-centered, look elsewhere: Shopify-first brands get almost nothing here, and Walmart and TikTok Shop coverage, while improving, is visibly secondary. If you sell fewer than a handful of products and research rarely, the free plan plus Jungle Scout's cheaper tiers or straight Seller Central reports may cover you. But if Amazon is where your money lives - or you want a service business built on seller data - Helium 10 remains the least-optional subscription in the space, and the free plan is the honest way to find out before paying for it.
