As AI generates code at unprecedented speeds, critical architectural context evaporates. Without a proper memory layer, engineering teams build on foundations they increasingly don't understand.
Important decisions are scattered across chat logs, PRs, and engineers' minds—most teams lose up to 85% of architectural context when relying on tribal knowledge.
Traditional docs can't keep pace with AI-accelerated development, quickly becoming outdated and leaving teams without reliable records of why decisions were made.
Engineers merge AI-generated code without understanding system-wide impact, moving from hoping changes work to costly production incidents that could have been prevented.
Arc preserves the critical context behind every code change and shows you exactly how new changes will affect your system before you hit merge—turning hope into certainty in the era of AI-accelerated development.
When reviewing this authentication service change, Arc shows you:
The original design decisions behind the code
The predicted impact of the change
Proof that the change was properly tested
Arc highlights potential issues before they reach production, keeping your system reliable even as development accelerates.
