Fantasy is the slowest-burn category to validate because most of what makes it work — magic system, POV, magic-tech balance — only shows up after chapter one. You need a way to test the premise before you commit to a 90,000-word draft.
AuthorPilot scores fantasy premising across Market Fit (which sub-niche — epic, romantasy, urban, grimdark — and where demand is moving), Originality (magic system novelty, POV freshness), Audience Fit (who exactly this is for at launch), and Genre Competition (comp density in your sub-niche).
The same weighted 0–100 read applies whether you write epic, cozy, progression, or grimdark — and tells you which rewrites move the score most.
