My crazy SEO experiment

I noticed that one website submagic.co is trending and getting a lot of traffic from Google. Basically, it can add captions to your videos. However, it is not free (your videos will be watermarked in the free plan) So I built the free alternative on submagic.pro Basically you can add captions to your videos for free My Aim is to rank for the keyword Submagic. I thought if I offered the same thing for free then users would use my website. What if I did not succeed No problem, I will release the code on GitHub. so you can add captions to your videos for FREE What you think of my crazy experiment?
