How ClearCart works
The plain-language version of what the extension does on every search, what it reads, what it never touches, and how to change its mind.
1. Every listing gets a score
When an Amazon or Walmart search page loads, ClearCart reads each result card the way you would: the title, the brand, how many reviews it has, the star rating, the price, any struck-through "list price", and whether the marketplace has given it a badge like Best Seller. It never opens the listing, never loads anything extra, and never sends any of it anywhere. From those facts it adds up a score from 0 to 100. Higher means more like junk.
Listings over the line are folded into a bar. Listings just under the line stay visible with a small tag. Everything else is left exactly as it was.
ClearCart: borderline
2. What pushes a score up
| Signal | What it looks like |
|---|---|
| Made-up brand name | ZQXWK, FRTZKO, GiKfUn. Random letters, no vowels, ALL-CAPS strings, or capital letters scattered through a word. ClearCart compares the letters against how English words are actually built. |
| No brand at all | "Wireless Earbuds, Bluetooth 5.3 Headphones HiFi Stereo 50H Playback…" with no name anywhere. Real sellers put their name on the listing. |
| Inflated list price | A struck-through "typical price" of $249.99 on a $19.97 item. Real sales top out around half off; a permanent 90% discount is theatre. |
| Keyword-stuffed title | "2026 Upgraded … for Men Women Kids … Gifts for …", 200-character comma chains, model-number soup, 【brackets】 and ★ in the title. |
| Almost no reviews | An unknown brand with fewer than 100 reviews, more so under 10. Combined with a perfect 5.0 from a handful of reviewers, more still. |
| Sponsored with almost no reviews | Paying for the top of the page before earning a single review. Sponsored on its own is not held against a listing. |
| Copycat listings | The same product relisted under several different made-up brands with near-identical titles, sometimes even sharing one pool of reviews. These collapse together as "near-identical listing ×6". |
3. What pulls a score down, or switches it off
- 4,000+ established brands are recognized outright, from DEWALT to TOZO to Govee to Silentnight. A recognized brand is never hidden by the score.
- Real review volume. An unlisted brand with 2,000 reviews gets credit; with 10,000 it gets a lot. That is how brands with odd names but long track records stay visible.
- Marketplace badges. Best Seller, Overall Pick, Amazon's Choice and Small Business count in a listing's favour once it has real reviews behind it.
- Store brands such as Amazon Basics, Great Value, onn. and Mainstays are never treated as junk. Pro can tag or hide them if you prefer.
- Close calls are not hidden. Anything within a few points of the line gets the "borderline" tag instead, so a clean page still shows you that the filter looked at it.
4. Nothing is deleted, and you can change its mind
- Click any bar to bring that listing back for this page.
- "Not junk? Tell us" on every bar opens a short form. A person reads every suggestion, and brands that check out are added for everyone in the next update. You can also nominate junk that keeps getting through.
- The popup shows how many listings were hidden, how many were checked, and a breakdown of why. The refresh circle re-scores the page with your current settings.
- The switch in the popup turns ClearCart off entirely, per browser, in one click.
5. Free and Pro
Free is the whole filter. Everything above, on Amazon and Walmart, forever. Pro is the set of controls for people who want to tune it:
- Hide every sponsored listing, not only the junk ones.
- Strictness presets: lenient hides only the obvious cases, strict casts a wider net, or set your own weights.
- Your own always-show and always-hide brand lists, with a one-click ✕ on any listing.
- Store-brand handling and a minimum review count.
- On product pages: a best-value-per-unit badge, a price history built only from your own visits, and warnings for inflated list prices and auto-generated seller names.
Pro is switched on for your first 14 days, with no email or card, so you can see what it does. After that it is $13 a year, or, until December 31, $29 once for life.
6. Where it runs, and where it never runs
Amazon's English-language sites (United States, Canada, United Kingdom, Australia, India) and walmart.com, and only on search-result and product pages. It is never active on cart, checkout or account pages. Other Amazon marketplaces are left alone on purpose: the brand model is English and would wrongly flag legitimate German or Japanese brands.
7. Privacy
All of the above happens inside your browser. ClearCart has no server, no analytics and no account. The one network request it can ever make is the license check for the optional Pro purchase. The popup's Diagnostics panel lists exactly which page elements it reads, and if Amazon or Walmart changes its layout, ClearCart steps aside rather than breaking the page.
