How we grade them
| 2.4GPAHelium 10Fair | 1.4GPAZonGuruWeak | |
|---|---|---|
| Value for money | CPlatinum, the plan for sellers under $100K a year, is $99 a month billed annually ($129 monthly). That's inside the normal range here, but it's mostly research. Ads automation, profit and loss reports and the AI agent need Diamond at $279. | DGraded against the suites it's listed beside. Helix Starter is $124 a month billed annually at $1,490 ($149 monthly) for 15 watched listings and 5 rewrites. Helium 10's Platinum is $99 with an AI listing builder and all its research, and extra Helix rewrites are $49 each. |
| Free plan and trial | CA free account with no end date, but with limited uses of each tool and of the Chrome extension, for one user. Enough for a look round, not for running a store. | DThe free AI Readiness Score rates a live listing from 0 to 100, with no card. It doesn't rewrite or watch anything, though, and there's no trial of Helix itself, so the free part does none of the paid job. |
| Features | BBlack Box and Xray for product research, Cerebro and Magnet for keywords, an AI listing builder, rank tracking, profits, inventory, review requests, refunds and ads. It covers the whole job and reaches Walmart and TikTok Shop, though ads and P&L need Diamond. | DHelix does one narrow job, listing copy: scoring, rewriting, publishing and nightly checks. Only the US and UK marketplaces are covered, and ZonGuru's older product and keyword research is gone from its pricing page. |
| Ease of use | CNo rating on record. It's a big suite with a lot of separately named tools to learn, and seller and ad accounts to connect before most of it works. | CNo rating on record. The score needs nothing, but Helix needs a Seller Central connection on a Professional selling plan, and you approve each rewrite before it goes live. |
| Platforms and integrations | BWeb and a Chrome extension, with no phone or desktop app on record. It connects to Seller Central, Amazon Ads, Walmart and TikTok Shop, and its MCP lets Claude and other AI tools query your data. | CWeb only, on the US and UK Amazon marketplaces. It connects to Seller Central, and every plan includes MCP access for Claude or another AI tool. No phone or desktop app. |
