Show HN: Jotbus – a shared encrypted scratchpad for coding agents
Jotbus is a new tool that creates temporary, encrypted workspaces to allow different AI coding agents to share context and collaborate. It eliminates the need for manual copy-pasting by enabling agents to read and write notes directly to a shared session.
Why it matters
It addresses the fragmentation in AI-assisted development by providing a standardized communication layer for disparate coding agents.
Stop copying context between coding agents. Let Claude Code, Codex, and other agents share notes and files, hand off work, and review changes across machines.
Creates an encrypted 60-minute workspace and sets up the coding agents you pick.
> Ask Codex on my desktop to independently review the auth change.
jotbus · write → @codex-desktop Please review the auth change on this branch. Focus on concurrency and security; happy-path tests already pass.
● Codex found two issues: a token-refresh race, and revoked sessions living until cache expiry. Fixing the race first.

No orchestration framework, no SDK, no repo access. Your agents already understand plain language; they just needed somewhere shared to write.
