Which one is for you
Pick Zonbase if
- Fits if you're researching products and keywords before sourcing a new Amazon listing
- Works for sellers who also want an FBA course alongside the tools
Look elsewhere if
- Tight on Standard: 10 searches a day in the main research tools
- Watch out: pricing page figures don't match its FAQ in places, so check the price at checkout
- Pricey if you want more volume: Legendary is $109 a month and Diamond $299
- Skip it if you want finished services, since the $1,997 Plus Plan is a done-for-you offer with a waiting list
- Watch out: the free trial is 7 days, and it appears to ask for a card
Pick ZonGuru if
- Fits if your listings need rewriting and you'd rather not do it yourself
- Works for agencies looking after listings for several US or UK Amazon clients
Look elsewhere if
- Skip it if you sell outside the US and UK
- Pricey if you only need a few listings fixed, at $124 a month for 5 rewrites, with extras at $49 each
- Not for you if you were after ZonGuru's old product and keyword research
- Watch out: Helix needs a Seller Central connection on an Amazon Professional selling plan
- Tight if you want to try the rewrites first, as the free score rewrites nothing and Helix has no trial
How we grade them
| 2.0GPAZonbaseFair | 1.4GPAZonGuruWeak | |
|---|---|---|
| Value for money | CStandard is $49 a month, or $399 billed annually, level with the middle of what Amazon seller tools charge at $49. | 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 | DA 7-day free trial that says you can cancel in one click, which suggests a card is taken. Nothing free after it. | 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 | BProduct database, keyword tools, sales estimator, rank tracking, listing helper and an extension. The listing names no gap in the core job. | 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 store rating on record. Seven tools and a training course mean some setup and learning. | 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 | CWeb and a Chrome extension. No API or integrations are listed. | 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. |
| Best for | Amazon product and keyword research | rewriting Amazon listings for AI shopping |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
