Example output
This is what you get back.
Illustrative excerpt. Your report will be specific to your PRD with named sources.
Market alignment score
Strong directional alignment with current market signal. 4 assumptions need revisiting before ship.
Evidence coverage
Three assumptions could not be corroborated with dated sources — flagged inline in the report.
Blind spot
“AI workflow adoption assumptions lack supporting evidence.”
Your PRD assumes mid-market PMs are adopting AI workflows. Available signal data doesn’t corroborate this in your target segment — recommend validating before prioritizing build.
Competitor signal
“Company X expanded AI automation capabilities in March 2026.”
A named competitor shipped overlapping capability in the last 60 days. Your differentiation positioning needs updating.
Recommendation
“Validate customer demand before prioritizing roadmap investment.”
Run a 2-week customer-signal sprint on the AI workflow assumption before committing engineering. Two blind spots and one competitor move materially change the risk profile of shipping as-written.
