Quick Answers

What tools do you need?

Just the platform account.

How much does it cost?

No paid tools needed: this case uses only the platform itself, which is free to join.

Is it allowed?

Follow the platform rules and disclose ads.

Watch out: Self-reported; the launch ARR and the listed monthly figure differ, so treat both as rough. Remix formats, not other people's footage.
