Does your marketing sound like your product, or your category?

Caught myself today writing “learn it in your time” on a IG carousel for my guitar app. Perfectly fine sentence. Completely wrong for us. Every competitor in my category sells learning — lessons, levels, progress. My whole bet is the opposite: you already know the song, you just can’t play it yet. The moment I use their vocabulary I’m a cheaper version of them. Changed it to “play it in your time.” One word. I think most early-stage products default to category language because it’s the language that exists. Curious whether anyone’s found a way to catch this systematically rather than by accident.
