Evidence-based search
Know what's true before you trust a website.
Sourken checks what websites claim against official government sources and published research, then shows you the evidence right in your search results. No one can pay for a better label.
Free account to see labels. Works on Google, Bing and DuckDuckGo.
The problem
The top of the page isn't proof.
What ranks first and what's true aren't the same thing. Ads are placed partly by what advertisers pay, and reviews can be bought. Sourken shows you what the evidence says, so you don't spend your time and money on claims that don't hold up.
Where a search ad appears depends partly on how much the advertiser bids, alongside ad quality and other factors.

In 2024 the Federal Trade Commission finalized a rule banning fake reviews and testimonials, including AI-generated ones, and their sale or purchase.

How it works
Search the way you always do.
See the evidence on every result
Sourken adds a label beside each search result it has checked: strong, mixed or limited evidence, with the date and a one-line reason. Ads are marked as paid placement.
Open the full report
Every claim on the page, its verdict, and the exact quotes and links from official sources and research behind it. Read the proof yourself.
Check any page on demand
Not checked yet, or over 90 days old? One click checks it now, in about two minutes, and the result helps everyone who visits after you.
The Sourken Score
One number, with the proof behind it.
Every full report opens with its Sourken Score: of the claims Sourken could check, how well they hold up against the evidence, out of 100. Claims nobody can check are counted separately, so a page can't look better by being vague.
- Strong evidenceOfficial sources back what the page claims.
- Mixed evidenceSome claims hold up and some don't, or only in part.
- Limited evidenceMost claims aren't backed by official sources.
- Not enough evidence yetToo few checkable claims to judge.

Our promises
Held to our own standard.
We never sell placement
No one can pay for a better label, score or position. Not advertisers, not licensees, not the businesses we check.
We show our work
Every verdict comes with the quotes and links that support it, so you can check us too.
We judge evidence, not people
Labels describe what a page claims and what the evidence says. They aren't a verdict on a business.
We date everything
Every label carries its date, and labels over 90 days old say so.
Questions
Frequently asked
What does Sourken check?
The factual claims a web page makes: what a product does, what the law requires, what research shows. Each claim is checked against official government sources and published research, and the report shows the exact quotes and links behind every verdict.
Does Sourken judge whether a business is good or bad?
No. A label describes the evidence behind what a page claims, not the business, its service or its people. A strong label means official sources back the claims; a limited label means they mostly don't.
Can a business pay for a better label?
No, never. No one can pay to change a label, a score or where a site appears. Businesses pay only for checks, the same as anyone else, and the evidence decides the result.
Why do some labels say they're over 90 days old?
Pages change. Labels never disappear, but after 90 days they say how old they are, and checking again is one click. Each new check adds to the page's history.
What does it cost?
Seeing labels in your search results is free with an account. Full reports and new checks use credits: $59 for 10, with optional automatic reloads. A site's verified owner sees the reports on their own pages free.
Which browsers and search engines work?
Sourken is a Chrome extension, so it also runs in Edge and other Chrome-based browsers. Labels appear on Google, Bing and DuckDuckGo results.
Is my searching private?
Yes. To find labels, the extension sends only short codes made from each result's address, never your search or the pages you visit. A page's address is sent only when you ask Sourken to check that page or open its full report.
