The differences that matter
One standard instead of three personalities
Personas can be fun, but when the reviewer changes, so does the yardstick. Song Refiners scores every song against the same rubric, so when your score moves on a revision, it is because your song got better.
The writing gets its own scores
Song Refiners breaks the songwriting into Title, Top Line and Lyrics as separate scored categories, so you know whether the problem is the hook, the opening or the second verse.
Built for the revision loop
Reviews start at $1, Refinery membership brings them to about $0.60, and revision reviews compare every part against your last version. Cheap, consistent feedback is what makes revising worth it.

- You want mastering and lyric videos in the same place as your feedback

Choose Song Refiners if
- You want the songwriting itself scored in detail, title and top line included
- You want one consistent standard, so a score change means the song changed
- You want to ask your reviewer follow-up questions right inside your review
