Sci-fi is the genre where the premise does almost all of the selling — and where comp overlap burns books fastest. A near-future thriller with a half-thought-out AI framing can look fresh on paper and vanish on launch because there are already 40 good comp titles doing the same thing.
AuthorPilot weights Market Fit (sub-niche demand — space opera, hard SF, near-future, cli-fi, post-apocalyptic), Originality (the central speculative idea), Audience Fit (which reader), and Genre Competition (comp density in your lane).
The same weighted 0–100 read applies whether you write hard SF, space opera, cli-fi, or post-apocalyptic — and tells you which rewrites move the score.
