No. Upload any track and go. If you already have AI covers, paste the link and they arrive with names and avatars attached - no re-uploading.

Your call. Fair races are seeded and reproducible. Rigged races let you pick the winner or the whole finishing order, and RaceCut finds a physics run that produces it. Nothing is faked in post.

Yes - the same simulation and renderer run in your browser and on our render servers, frame for frame. Free renders happen on your device; paid plans render on GPUs so you can batch.
