It’s very common in presentations, professional emails, and even long stories told over coffee.

If you say it two seconds after the first time, you might just sound like a glitching robot.

A very common error is mixing up the preposition. People often say ✗ As I mentioned about or ✗ Like I mentioned before.

This is grammatically fine, but it feels much more aggressive. Mentioned is soft and professional; Told sounds like a parent scolding a child.
