It's a scam app. Dont pay.
It's a scam website. Asks you to create a workflow eg add music, create a prompt, then wants you to sign in saying you get free credits. Then you sign in. Then says free credits insufficient. Wants you to sign up for a hobby plan to buy credit. You pay 9.50$ for a hobbyist plan. Guess what. The credits aren't sufficient for the very first request you made before signing up for 'free' account. Asks you to upgrade to pro plan. Imagine paying 9.5$ and not being able to even deliver 1 piece of music. Shameless people who don't even have a proper customer care. Been waiting for hours on their discord channel.
