Your AI agents are everywhere: terminals, browsers, desktop apps. handup connects them all to one inbox. Agents ask before risky steps and show you the real thing (the command, the diff, the email), and you approve or deny from your desk or phone. They also send you finished work and updates: files, reports, previews. Say no with a reason like "use staging" and the agent changes course. Works with Claude Code, Codex, Cursor and any MCP agent. Local, no account.
