How it works
From raw evidence to shipped spec in four steps
1
Capture evidence
Import from Dovetail, Amplitude, surveys, analytics, and more. Tag every insight to a claim.
2
Draft with AI
AI Guide drafts sections grounded in your evidence. You stay in control — every word is editable.
3
Track readiness
A live readiness score shows coverage gaps. Ship when the score says you're ready, not when it feels right.
4
Review & ship
Stakeholders sign off async. Arc generates a full audit trail from first draft to shipped.
