The 4-axis validation flow
How BookScore™ works
One short form in, one weighted 0–100 score out — across four independent axes.
Step 1 · Your inputs
What you paste in
Four short fields. Nothing in your manuscript — just the working idea, who it's for, and where it sits in the market.

Step 2 · The 4 axes
Four independent lenses, one weighted score
Each axis is scored 0–100 on its own, then blended using the weights below (total weight sums to 100%).

Originality
How differentiated the premise is from existing comps in the same lane.

Audience Fit
Is the target reader clearly defined, reachable, and likely to convert at the price point?

Genre Competition
How saturated the niche is — and how clearly your title can stand out from the comp set.
Step 3 · What you get
A peek at the score
Each axis contributes its score × weight to the final 0–100 number. The math is transparent — here's three rows from the live sample:
