Audio Tools Website (acapella generator / karaoke Maker / Vocal Remover)

Hi all

I've made a website using Spleeter (the awesome tool from Deezer to split vocals and instrumental from a song)

https://www.edityouraudio.com

• Vocal Remover to get only the instruments tracks and practice your singing
• Acapella generator to get only the vocals and practice your guitar/piano/....
• Karaoke Generator that will automatically get back the lyrics of the song and generate the synced Karaoke for you

It is online and we get some traction but are not making any money yet.
We wonder if we should keep the service free (as we love free services) and get money otherwise, or make a premium paying service to get more done.

Let me know what you think !

Thanks
