Tap "Check this product"
We read the brand, name, price and ingredient list, research the product, and verify every citation by fetching it.

Read the verdict
Worth it, skip it, or depends, and why. Each claim with its evidence and source. Alternatives that say what differs: same formula for less, better formula at a similar price.

Questions people ask
What happens when I submit my list?
We check each product the same way the extension does and email you the verdicts, along with the install link. One email. If you install the extension first, the products on your list open instantly.
Which stores does it work on?
Any https store: Amazon, Walmart, Target, Sephora, Ulta, Best Buy, and every brand's own site. The badge appears when the page sells a product.
Does it cost anything?
No. Five new checks a month are free, and a product anyone has already checked is free to open as many times as you like. The first sign-ups get a year with no monthly limit at all: create your account in the extension with the same email and it applies on its own.
What does it read from the page?
The product's brand, name, price, ingredient or spec list, and the site's domain. Not the full page address, not the page's HTML, not your browsing history, not other sites' cookies. On a page that isn't selling something it sends nothing.
Where do the verdicts come from?
A research model, then our own checks: every cited page is fetched and verified, dead or off-topic sources are dropped, and confidence is capped to what the surviving sources support. A verdict with thin sources says so.
What about the affiliate links?
