LANDR

LANDR started as an automated mastering service and is still known for it. You upload a finished mix, choose a style and loudness, and it returns a mastered version you can compare against the original before downloading. It also offers sample packs, plugins, collaboration tools and distribution to streaming services.

For creators who make their own intro music or score their videos, mastering is the last step that makes a track sit at a sensible level next to everything else on a platform. Listen on headphones, a phone speaker and a laptop before you settle. If you plan to distribute music through it, read the distribution terms and how AI-generated material is treated, since stores and distributors set their own rules.
