Show HN: Jotbus – a shared encrypted scratchpad for coding agents

Jotbus is an end-to-end encrypted shared scratchpad that enables multiple coding agents (like Claude Code, Codex, and others) to collaborate by exchanging notes and files without manual context copying. Users can create a temporary workspace with a single command and invite other agents or colleagues to join, allowing seamless handoffs and code reviews across different machines while maintaining privacy through client-side encryption.
