Product
The PRD workspace that never loses its source
Arc Studio gives you a structured workspace for the full lifecycle of a product spec — evidence-in to sign-off-out.
Evidence model
Four grades. One standard.
Every claim in your PRD is classified so reviewers know exactly how strong the backing is.
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.
Review & sign-off
Ship when the score says ready
Stakeholders review and sign off async. Arc tracks every approval and surfaces the readiness score in real time.
Capabilities
Everything a modern PM team needs

Real-time collaboration
Multiple PMs and stakeholders can edit and comment simultaneously with live presence.
📜
Version history
Every change is tracked. Diff any two versions, restore at any point, audit who changed what.

Embed live charts from your BI tool directly in the PRD, linked to the claim they support.
