AMZ Evaluator is a single-purpose Chrome extension from Raybek Solutions that overlays keyword and demand data on Amazon search results — estimated sales, revenue, BSR, result count and average price — and scores a keyword against a fixed KDP criterion its vendor calls the 3R method. The first thing to settle is the price, because the product carries two published numbers on the same day: the vendor’s own page advertises $9.99 a month, while the Gumroad listing it sends you to is a $17.99 a month membership (both read 2026-08-31). It is US marketplace only, desktop Chrome only, and its Chrome Web Store listing reports 1,000 users.
Pricing, features and listing statistics in this AMZ Evaluator review were read from Raybek Solutions’ own pages, the product’s Gumroad listing and its Chrome Web Store entry on 2026-08-31. This is a capability assessment built from public pages, not a hands-on test — amzfinder holds no paid AMZ Evaluator subscription and nothing below is our own measurement.
TL;DR
- What it is: a Chrome extension that reads Amazon search results and returns keyword analysis for Private Label, KDP and Merch ideas, plus sales estimates, average price, average sales rank and review count (checked 2026-08-31).
- Two prices, both official. raybeksolutions.com/tools/amz-evaluator/ states “Get started for $9.99. Then $9.99/mo cancel any time.” The Gumroad product it links to is priced at $17.99/month. Neither page mentions the other’s number.
- The $9.99 is a founding-member offer, not the list price. The vendor page frames it as a “special founding member price” that “will promptly increase after 100 subscribers,” and its buy button carries a Gumroad discount code against the $17.99 monthly plan.
- US only. The vendor’s own warning: “AMZ Evaluator currently only works on the US marketplace.” It also requires desktop Chrome on Windows or macOS and does not run on iOS or Android.
- No free tier and no trial. Gumroad lists it as a monthly membership with no free trial; the safety net is a 30-day money-back guarantee.
- Small footprint. 1,000 users and a 3.5 rating from 2 ratings on the Chrome Web Store; last version 1.0.29, published 15 February 2026 (checked 2026-08-31).
- Best for KDP authors who want one cheap number-checker on Amazon.com search pages. Skip it if you publish outside the US, need rank tracking, or want a keyword database you can query away from a search page.
What AMZ Evaluator puts on an Amazon page
The product is deliberately narrow. Open the extension while browsing Amazon and, per the vendor’s own copy, you get “critical sales data like estimated sales, revenue, BSR, # of search results, and price” for the search term you are looking at (raybeksolutions.com, checked 2026-08-31). The Chrome Web Store listing states the same feature set in list form: keyword analysis for Private Label, KDP and Merch keyword ideas, sales estimates, average price, average sales rank, and review count.
That is the whole product. No keyword database to query, no rank tracking over time, no listing editor, no reverse-ASIN lookup and no export is described on any page the vendor publishes. The unit of work is one search term at a time, evaluated where you already are.
Two scope limits are stated by the vendor rather than inferred. Marketplace: “AMZ Evaluator currently only works on the US marketplace,” printed as a warning on both the Gumroad listing and the store entry. Platform: “You will need the latest version of the Chrome browser installed on a Windows or Mac PC. This does NOT work on iOS or Android devices.” If you publish into amazon.co.uk or amazon.de, this tool has no data for your market — a limit no subscription fixes, and the same trap we mapped in KDP research tools outside the US .
On data handling, the Chrome Web Store records that “the developer has disclosed that it will not collect or use your data,” and its declarations state the data is not sold to third parties (checked 2026-08-31).
AMZ Evaluator pricing: two published numbers
This is the part a buyer has to get right, so here are both figures with their sources rather than a single headline.
| Where you read it | Price | Billing | What the page says |
|---|---|---|---|
| raybeksolutions.com/tools/amz-evaluator/ | $9.99 | Monthly, cancel any time | “Get started for $9.99. Then $9.99/mo cancel any time.” Framed as a “special founding member price” that “will promptly increase after 100 subscribers.” |
| jpcoder.gumroad.com/l/amzeval | $17.99 | Monthly membership | The listing’s own product data prices the single monthly tier at $17.99 and records no free trial. |
Both read 2026-08-31. The two numbers are reconcilable: the vendor page’s buy button does not open a $9.99 checkout of its own — it links to the same Gumroad product with a discount code appended, and that checkout URL still carries the $17.99 monthly plan as the underlying price. In other words, $17.99 is the list price and $9.99 is a coupon on it. The amount actually charged after the code applies could not be confirmed from public pages, because Gumroad calculates it at checkout behind a login.
One note on the founding-member framing: the promise is that the price rises after 100 subscribers, while the Chrome Web Store reports 1,000 users. Installs and paid subscribers are not the same population, so the figures do not strictly contradict — but the offer has been running a while. Refunds are the one place both channels agree: a 30-day money-back guarantee, stated on the vendor page and recorded as the refund policy on Gumroad (checked 2026-08-31).
The 3R method, and what a fixed criterion can decide
The differentiator AMZ Evaluator markets is not the data but the built-in judgement. The vendor page describes it as “Jenni Hunt’s proven method to determine if a keyword for KDP is worth pursuing or not called the 3R method. It analyzes Results, Rank, and Reviews to immediately tell you if a keyword will be successful,” and states the criterion ships with the extension.
Taken at face value, that is a real convenience. Result count, average sales rank and review count are the three numbers a KDP author eyeballs when sizing a niche, and thresholding them into a yes/no removes the step where you decide what “too competitive” means. For someone who does not want to learn a research suite, the preloaded rule is the point of the purchase.
The limits are structural rather than a flaw in the execution. A fixed threshold set encodes one person’s tolerance for competition and cannot be tuned to your category, price point or ad budget — the vendor pages describe no settings for it. A keyword that passes 3R is one worth reading further about, not a validated niche. The vendor’s stronger claims — “stop spending money on ads,” “the secret weapon behind hundreds of Amazon sellers and authors” — are marketing copy carrying no supporting figures, and we found no independent data behind them.
Maintenance signals, and the sibling extension that outgrew it
The public record on maintenance is unusually easy to read here, because the same vendor ships a second Amazon extension and the two listings sit side by side.
| Chrome Web Store listing | Users | Rating | Latest version | Published | Markets |
|---|---|---|---|---|---|
| AMZ Evaluator | 1,000 | 3.5 (2 ratings) | 1.0.29 | 15 February 2026 | US only |
| AMZ Suggestion Expander (same vendor) | 200,000 | 3.1 (109 ratings) | 2.1.53 | 17 August 2026 | US, CA, MX, UK, DE, FR, IT, AU, ES |
Both listings read 2026-08-31. The contrast is the finding. AMZ Evaluator’s changelog runs “Bug fixes” for versions 1.0.27 through 1.0.29, the last substantive entry being v1.0.26, “Upgrade to manifest v3” — the migration Google required of every extension. The free sibling shipped a feature release two weeks ago adding a backend search-terms builder, saved keywords, a 12-month trend chart and XLSX or CSV export, and carries the store’s “Featured” badge.
The vendor site is consistent with that. raybeksolutions.com publishes eight pages in total per its own sitemap; the About page opens with a real sentence — “We are a family owned and operated business based in central Arkansas” — then runs Lorem ipsum through four of its five remaining sections. The footer carries the theme’s default contact details ([email protected] , a Washington DC address, 1-800-1234-567), the page at /tools/ase-notice/ contains the single line “This is a message,” and the newest blog post is dated 17 February 2024 (all checked 2026-08-31).
None of that says the extension returns wrong numbers, and 1.0.29 shipping in February 2026 is recent enough that it is plainly not abandoned. It does set the expectation for the subscription: bug fixes on a US-only feature set, not a roadmap. We track that signal across the category in our Amazon seller tool status page directory .
How AMZ Evaluator compares on cost
The comparison KDP authors actually make is against the tools that cover the same research job, so here is where the money lands.
| Tool | Price | Model | What you get for it |
|---|---|---|---|
| AMZ Evaluator | $9.99 promotional / $17.99 list, monthly | Subscription | On-page keyword metrics and the 3R pass/fail, US only (checked 2026-08-31) |
| Publisher Rocket | $199 | One-time | Keyword, category, competition and AMS research; reverse-ASIN capped at 50/month (checked 2026-07-31) |
| BookBeam | $47 / $69 / $119 monthly | Subscription | Book tracking, rank tracking and reverse-keyword lookups; the useful tier starts at $69 (checked 2026-08-08) |
| Book Bolt | From $9.99 monthly | Subscription | KDP Spy research plus design and listing tools; KDP Spy is also US-only (checked 2026-08-07) |
| Helium 10 | Free plan, then Platinum $129 monthly ($99 annual) | Freemium subscription | Full research suite; complete profit reporting only from Diamond, $359 monthly / $279 annual † |
† Helium 10 figures per our tier reference, read from helium10.com/pricing on 2026-07-18; verify current pricing before buying. Our Helium 10 review maps its tiers in full.
Two things fall out of that table. First, at the promotional $9.99 AMZ Evaluator is priced against Book Bolt’s entry plan while doing a fraction of the work — Book Bolt bundles design and listing upload alongside its research extension, and its KDP Spy listing reports 50,000 users against AMZ Evaluator’s 1,000 (checked 2026-08-07 and 2026-08-31 respectively). Second, at the $17.99 list price the break-even against Publisher Rocket’s one-time $199 lands just under twelve months, and Publisher Rocket is not restricted to reading a search page.
What AMZ Evaluator genuinely undercuts is the entry decision: no annual commitment, no onboarding, one screen to learn — the same trade-off we cover for research extensions generally in 9 Chrome extensions for Amazon FBA sellers .
AMZ Evaluator scorecard
Scores reflect a capability assessment of vendor pages, the Gumroad listing and the Chrome Web Store entry (checked 2026-08-31) against our 8-dimension scorecard methodology — judgment from public evidence, not a lab benchmark.
| Dimension | Score | Why |
|---|---|---|
| Accuracy | 2.5 / 5 | Unverifiable from outside: no published methodology for the sales and revenue estimates, no stated data source, and undisclosed 3R thresholds. Two store ratings is too small a sample to read either way. |
| Ease of use | 4.5 / 5 | The strongest dimension. One extension, one screen, one verdict per keyword, and a preloaded criterion that removes the interpretation step. |
| Depth | 1.5 / 5 | Five metrics and a pass/fail. No keyword database, reverse-ASIN lookup, history, export or saved lists — several of which the vendor’s own free sibling now has. |
| Automation | 1.5 / 5 | Nothing runs unattended. The extension reports on the page you are looking at; there is no tracking, no alerting and no scheduled refresh. |
| Team Fit | 1.5 / 5 | A single-seat browser extension with no described seats or shared workspace. Fine solo, structurally unsuited to a team. |
| Support | 2.0 / 5 | A published support email and phone number on the store listing, plus the 30-day guarantee. No hours, no SLA, and the vendor site’s contact block carries placeholder details. |
| Pricing | 3.0 / 5 | Cheap in absolute terms and cancellable monthly. Marked down because the advertised $9.99 is an undisclosed coupon on a $17.99 list price, and because no free tier or trial exists to test the fit. |
| Stage Fit | Foundation | Sized for a first-time or occasional KDP publisher validating US keywords. Anyone tracking a catalogue, publishing internationally or buying ads has outgrown it on day one. |
Who should buy AMZ Evaluator, and who should not
Buy it if you publish to Amazon KDP in the US, you want the demand numbers for a search term while you are looking at that search term, and you would rather follow a fixed rule than build your own thresholds. At the promotional rate it costs less than a month of any research suite, and you can cancel after one project.
Do not buy it if your market is outside amazon.com. That single limit disqualifies it for most non-US publishing, and there is no partial workaround.
Think twice if you research in bursts a few times a year. On a subscription you pay in the eleven months you are not researching; a one-time tool like Publisher Rocket does not, and the routes are compared in Publisher Rocket alternatives .
Check first what you would pay in month two. Sign up through the vendor’s own page so the founding-member code applies, then read the Gumroad receipt — the list price behind that checkout is $17.99, and the 30-day guarantee is the window to change your mind.
FAQ
How much does AMZ Evaluator cost? Two numbers are published. The vendor page advertises $9.99 to start and $9.99 a month thereafter, cancellable any time; the Gumroad listing it links to prices the monthly membership at $17.99. Both read 2026-08-31. The $9.99 is presented as a founding-member offer applied as a discount code against the $17.99 plan.
Is there a free version or free trial of AMZ Evaluator? No. The Gumroad listing records no free trial and no free tier, and neither the vendor page nor the store entry describes one; the refund route is the 30-day guarantee (checked 2026-08-31). The same vendor’s AMZ Suggestion Expander is a separate free extension covering search-suggestion expansion, not keyword evaluation.
Does AMZ Evaluator work outside the United States? No. The vendor states it “currently only works on the US marketplace” on both its store listing and its Gumroad page (checked 2026-08-31). It also requires desktop Chrome on Windows or macOS and does not run on mobile.
Is AMZ Evaluator still maintained? Version 1.0.29 was published on 15 February 2026, and versions 1.0.27 through 1.0.29 are logged only as “Bug fixes”; the last substantive change was the manifest v3 migration in 1.0.26 (checked 2026-08-31). The extension is current enough to keep running, but the vendor’s release activity has moved to its other extension.
What is the 3R method? The vendor’s built-in criterion for judging a KDP keyword, attributed on its page to Jenni Hunt and described as analysing Results, Rank and Reviews to say whether a keyword is worth pursuing. The thresholds are not published and no settings for adjusting them are described. For how these metrics fit together, start at the Amazon keyword research workflow hub .
How amzfinder compares seller tools
We read every tool against the same eight dimensions — Accuracy, Ease, Depth, Automation, Team Fit, Support, Pricing and Stage Fit (scoring methodology ) — and lead with what decides most subscriptions: published price, payment model, refund terms and what the free tier really covers. Where a claim could not be verified at first hand today, it is labelled as such above rather than smoothed over.
