Look elsewhere if
- Tight on Basic: it has no product, keyword or new-listing trackers
- Skip it if you want a long trial: the free trial is 3 days
- Pricey as you add trackers: Standard is $79, Advanced $129 and VIP $189 a month
- Watch out: plans show a crossed-out list price with no end date
- Watch out: yearly billing is $390, $790, $1,290 and $1,890 a year, which the page says saves 16%
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

Helix Starter is $124 a month billed annually at $1,490 ($149 monthly) for 15 watched listings and 5 rewrites.

More comparisons
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.
