Get it

Add to Chrome

From the Chrome Web Store. Works in Chrome, Edge, Brave and other Chromium browsers. Prefer to install it by hand? Download the zip.

Microsoft Edge: Edge installs Chrome Web Store extensions: open the Chrome Web Store link above in Edge and choose "Allow extensions from other stores" when Edge asks.

Firefox: download the Firefox package (Firefox 128 or newer). Until it is listed on Firefox Add-ons, load it from about:debugging → This Firefox → Load Temporary Add-on (it stays until Firefox restarts). Firefox asks you to allow it on each site the first time - allow Amazon and the sites you use.

Signing in

1. Press the Product Healer icon in your browser bar, then Sign in with Product Healer.
2. A tab opens on producthealer.tech showing a code. Check it matches the one in the extension and press Yes, sign it in.
3. That is it. You never type your password into the extension: you sign in on our own site, with your two-step code if you use one, and you can sign any browser out on Account → Chrome extension.

What it shows

• Product pages — Overview: price, rank, reviews and seller count (observed, with the date we last read them), the referral and FBA fees, what is left after them (and after VAT if your sourcing criteria say you are VAT-registered), and our sales estimate as a range with its caveat. Gaps are filled from the page and tagged "page"; Amazon's own "bought in past month", who sells and ships it, variations, list price, deal, first-available date and the 1-5 star split are shown as Amazon labels them, and the size and weight are read from the page's "Product information" table (folded or not) so the FBA fee can be worked out; for a product you track, the page's stock line ("Only 4 left", "Currently unavailable") and Amazon's Choice, discount and coupon badges are kept for your workspace and shown on Tracked Products; with your Amazon seller account connected, the fees are Amazon's own estimate; the break-even price, the most you can pay and — once you have typed your cost — profit, ROI and your verdict; one-click X-Ray, Sourcing Analyser, supplier search, List on Amazon, Copy Listings and Compare markets. One button tracks the product.
• Markets: the same product in every marketplace of your plan, from the figures we already hold - each price in its own currency, an approximate conversion when we have a rate, and "not held" where we have no reading yet. Nothing is looked up, so nothing is spent.
• Profit: type your cost and see every fee line, payout, profit, margin, ROI, break-even price, the most you can pay for your ROI target and — on plans with the Sourcing Analyser — your verdict, naming each rule that failed or could not be checked.
• History: daily price and rank readings for products somebody tracks. A missing day is a gap, never a made-up line.
• Search results: rank, sales estimate and price on every result we already hold figures for, an Add button, and a Look up button for the rest.
• eBay, TikTok Shop, Walmart and Etsy: the listing's price, postage, units sold, rating, reviews, watchers and seller as the page shows them, Amazon products we hold with a similar title (and a search of your own Amazon account if you ask), the price gap in the same currency, and what you keep selling there with YOUR fee rate. On their search and category pages every result gets a badge: price and units sold as shown, the Amazon product we hold with a similar title and the price gap - the whole page compared at once, spending nothing - and the page can be downloaded as a CSV file made in your browser.
• AliExpress, CJdropshipping, Alibaba.com and 1688: the price there as your cost, the Amazon profit, ROI and verdict on the matching product (converted at our stored rate, shipping included only when the page shows it), and one click to add it to Dropshipping.
• Shopify stores: press "Check this Shopify store" in the extension for the store's theme, currency and its own best-seller list.
• Listing tab: press "Score this listing" for our AI Scorecard checklist on the page's title, bullet points and description (read only when you press it, stored nowhere), and check whether Amazon's catalogue search finds the product for your keywords, through your own connected seller account.
• Profit in your currency: type a cost in another currency and it is converted at our stored rate (the date is shown; no rate = no profit), and choose which of your sourcing profiles judges it.
• Buy list: add the product, at your cost, to your Online Arbitrage buy list - from the Amazon panel or a supplier page (its price and link).
• Reviews: download the reviews showing on the page as a CSV file, made in your browser - no reviewer names.
• In the toolbar: your unread Product Healer notifications as a count on the icon, the products you opened lately (kept in this browser only), and a box to check a pasted list of ASINs against the figures we hold. On search results, "Can I sell?" asks Amazon for your account when you press it.
• Keyword box: for the words you searched, where they sit in your own Keyword Bank on each platform — autocomplete positions, a demand signal, not search volume — and one click to hunt them.

What it costs your plan

Figures we already hold, from any earlier lookup, cost nothing — on product pages and on every search result. Each new product read counts as one product lookup from your plan's allowance: on a product page automatically (switch that off in the extension to look up only when you press the button), on search, category and Best Sellers pages only when you press Look up, or "Look up all on this page" (one request, one lookup for each product actually read, after you confirm). The profit tab, history and keyword box never spend a lookup. A viewer in a workspace never spends lookups and sees only figures we already hold.

What it can reach

It asks Chrome for storage (its sign-in, your display choices, the costs and fee rates you type and the products you opened lately), alarms (to re-read your unread notification count from producthealer.tech every 15 minutes) and activeTab with scripting (only for "Check this Shopify store", on the tab you are on, when you press it), and talks to one site: producthealer.tech. It runs on Amazon product, search, category, Best Sellers and seller pages and reads the product IDs in the address and the results and the words you searched. Only when you press its button to use the page does it read the product page's public listing (title, price, rank, rating, reviews, size, weight) for that one fees and profit answer. On eBay, TikTok Shop, Walmart, Etsy, Noon, AliExpress, CJdropshipping, Alibaba.com and 1688 it reads only the product listing you open, and on their search and category pages each result's title, price and units sold. It stores none of it. When you open its Complaints tab it reads the reviews shown on that page (star rating and text) to find recurring complaints, and stores none of them. It does not read your own accounts, your orders, your passwords or any other page. Its panels are sealed off from the page, so Amazon's own scripts cannot read your figures or press its buttons.
