Affiliate links
- Today there are no affiliate links on this site and no paid placements. Links to tools are plain links to their official sites.
- If we add affiliate links later, each one will be labelled "Affiliate link" next to the link, and marked
rel="sponsored". Any YouTube description that carries an affiliate link will say "#ad" on its first line. - An affiliate link means we may earn a commission if you sign up, at no extra cost to you. It never changes which tools we cover or what we say about them.
Sponsorship
No tool has paid us to be covered. If that ever changes, the video and page will say so clearly.
AI-generated voiceover
Video voiceovers are AI-generated (synthetic) and screenshots are from each tool's public website. See About.
Independence
Signal Check (@SignalCheckRae) is not affiliated with, or endorsed by, the tools we cover, and is not connected with other products or sites called "SignalCheck".
