That sounds like a clickbait-style headline: “Millions of people around the world don’t know the secret of this tool.”
Without seeing the tool or the rest of the post, there isn’t enough information to know what “secret” it’s referring to. These headlines commonly exaggerate an ordinary feature or use a hidden function as the hook.
Send me the photo, screenshot, or link to the post, and I can identify the tool and explain what the supposed “secret” actually is—and whether the claim is true.
