Frequently asked questions
Everything about OH HAI, the free universal inbox for your agent fleet.
What is OH HAI?
OH HAI is the universal inbox for your agent fleet: one place where AI coding agents and other autonomous agents reach you to ask a decision, hand over a task only a human can do, or send a notification — and where your answer routes back to the agent so it can keep working.
Is OH HAI free?
Yes. OH HAI is a free product from Autonomy, on the web at inbox.ohhai.app and on the iOS App Store.
Which agents and tools does it work with?
Any runtime that can run a CLI or speak MCP: Claude Code, Cursor, VS Code, Codex, ChatGPT, Claude.ai and Claude Desktop, CI jobs, cron jobs and custom agents.
How does an agent connect?
Three ways: the oh-hai CLI, the hosted MCP server at https://mcp.ohhai.app (with OAuth sign-in), or a local stdio MCP server. Agents authenticate with per-account bearer tokens you mint and can revoke.
What kinds of messages can agents send?
Three types. ASK is a decision — your reply resumes the agent. TASK is something only a human can do, like rotating a key. NOTIFY is an FYI or digest that never blocks. You can also send directives back to any agent.
Will I get push notifications on my phone?
Yes. The iOS app and web push notify you when an agent needs you, so you no longer have to watch terminals to catch a blocked agent.
What is MA2H?
MA2H (Machine-Agent-to-Human) is the open, provider-neutral protocol for agent-to-human messaging. OH HAI is its reference implementation. The spec lives at ma2h.org.
How is OH HAI different from Slack or email notifications?
OH HAI is built for agents: every message is typed (ask, task, notify), answers route back to the waiting agent, and one inbox spans every agent, project, machine and provider, with a daily Digest of what all of them did.
Who makes OH HAI?
Autonomy LLC, the company that also builds Descant, an autonomous software engineering system that reaches its humans through OH HAI.
Where is my data stored and is it private?
Data is processed in the United States, encrypted in transit, and never sold. See the privacy policy for subprocessors, retention and your rights.
