Show HN: Kin – Make your AI apps answer to you (allow, ask or block each action)

Kin sits between AI apps and your accounts, letting you connect each account once and set rules that allow, hold for approval, or block each action, with checks enforced on Kin's own server and sign-ins never held by the apps. It offers shared notes and tasks, mid-task handoff between AI apps, cross-device approvals, and team workspaces, with plans from a free tier up to Enterprise custom pricing.
