For PMs
You write PRDs for a living. So does our AI. Let's see if it keeps up.
VibeManager runs a real lifecycle (brief, PRD, UX, architecture, stories, build) with you able to edit and steer every artifact. Pressure-test it. Sandra in London did; she's the reason this page exists.
Edit every artifact inline.
The brief, the PRD, the UX spec, the architecture, the stories: each one is a draft you own, not output you accept.
Change one thing; watch it propagate.
The Artifact Dependency Graph flags every downstream artifact that depends on what you changed, PRD to stories to code.
Export the whole bundle.
Markdown + JSON, ready for your own tools. Your artifacts are never trapped here.
Read the generated code.
No black box. No “trust us.” The diff is contained, reviewable, and yours to merge, or not.
