AI Testing Guide is free to read. Part of what pays for the testing, writing and hosting is advertising and affiliate links. This page explains exactly how that works so you can judge our reviews with full information.
Affiliate links
Some links on this site go to vendor websites through an affiliate or referral link. If you buy or sign up through one of those links, we may earn a commission. It costs you nothing extra and the price you pay is the same.
Where a page contains affiliate links, it carries a short note near the top. Not every link to a vendor is an affiliate link, and we link to tools we do not earn from when they are the right answer.
What affiliate links never change
- Ratings and verdicts. A commission never raises a score, removes a weakness or moves a tool up a list. Tools we do not earn from are reviewed by the same method.
- What we say about pricing. We check prices on the vendor site and show the date we checked, whether or not we earn from the link.
- Negative findings. If a tool disappoints in testing, the review says so, even when it has an affiliate programme.
You can read how we test in How we test.
Advertising
The site shows ads served by Google AdSense. Advertisers do not see or influence our content, and ads are never written or placed by vendors we review. You can choose your cookie and ad personalisation settings through the consent message, and our Privacy Policy explains how data is handled.
Free products and review access
When a vendor gives us a free account or plan so we can test a product, we say so in the review. Free access is never payment for coverage and the vendor does not see the article before it is published.
Questions or corrections
If you think a page is not clear about how we earn from it, or you spot an error, tell us through the contact page and we will fix it.
