How Gemini Notebook (NotebookLM)’s scores are calculated
The full audit trail, recomputed from the verdict data at build time through the same code that produced the leaderboard: verdict × quality × story weight per cell, cells sum to dimension scores, dimensions blend into the PA Score. Every number on the product page is reproducible from this page alone; for why the formula looks like this, see the methodology.
verdict factors: full ×1.0 · partial ×0.6 · disputed ×0.3 · none ×0.0 · n/a excluded from both sides · cell points = weight × quality × factor · cell max = weight × 10
PA Score7/100
Agent-ready 0.0 × 0.30 = 0.00
API quality 0.0 × 0.20 = 0.00
Openness 10.8 × 0.20 = 2.16
Built-in AI 33.8 × 0.15 = 5.07
Automation 0.0 × 0.15 = 0.00
(0.00 + 0.00 + 2.16 + 5.07 + 0.00) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 7.23 ÷ 1.00 = 7.2
Scores are stored to 1 decimal; the product page’s pills round to whole numbers for display. Each dimension below shows the stories, verdicts, and cited evidence behind its number.
