Change one thing.
See everything it breaks.
Move a requirement — ArcPM lights up every downstream screen and PRD section it breaks, and syncs them in one click.
Your plan drifts the moment you change your mind.
You change a requirement, patch the PRD, forget the prototype — and three weeks later ship what the PRD no longer says. Every PM has shipped that bug, because nothing connected the change to what it touched.
How it works
One connected graph
Your research, requirements, prototype, and PRD are one graph — every artifact knows what it came from.
Change lights up downstream
Edit anything upstream; every item that depended on it lights up instantly — precise to the screen and PRD section.
Sync in one click — or don’t
Sync it all at once, or keep what you meant to keep. The graph surfaces the drift; you make the call.
Why it’s different
ChatGPT generates a doc and forgets it. ArcPM keeps the thread across research, requirements, prototype, and PRD — so your plan flags its own contradictions before you ship them.
Stop losing the thread.
See your first “change one thing, watch the downstream light up” moment in minutes.
