✨ AI Guide

Drafting from 3 evidence items…

Evidence model

Four grades. One standard.

Every claim in your PRD is classified so reviewers know exactly how strong the backing is.

Strong

Controlled research, A/B tests, large-sample quantitative studies.

e.g. Amplitude experiment, 12k users, p < 0.01

Moderate

Qualitative studies with ≥8 participants or mid-sample quant data.

e.g. Dovetail interviews, 10 PMs, 3 themes emerged

Weak

Single data point, very small sample, or conflicting signals.

e.g. One support ticket, single session recording

Anecdotal

Team intuition, informal feedback, or untested assumptions.

e.g. "The CEO said customers hate this."

AI Guide

Grounded drafts, not hallucinations

AI Guide reads your linked evidence and proposes draft text for each section. It cannot introduce claims not backed by something you've added.
