M91

When AI agents or software need a human, M91 reaches the right person and keeps notifying until somebody responds. Your systems can do the work. M91 handles the one moment that needs a person: an approval, a decision or an action. The alert lands on the right phone, the answer goes straight back to your system, and work continues. SOFTWARE DETECTS → HUMAN ACTS → WORK CONTINUES WHERE TEAMS USE M91 • AI agents: approve or reject an action before your agent goes ahead • Payments: know the moment money stops moving • Infrastructure: wake the on-call person when something breaks at 2 AM • Devices and IoT: alert someone when a sensor, cold room or device needs attention • Security: reach the responsible person the instant an event is detected • Customer support: bring in a human when the bot runs out of answers • Sales and CRM: give a hot lead an owner straight away • Reminders: get things checked, approved or acknowledged on time WHAT M91 GIVES YOU • Answer buttons set by you or your AI, like "Approve", "Reject" or "I'm on it" • Critical alerts that escalate to a phone call if nobody answers • Send to a team and let one person take ownership • Broadcast to a whole channel • See who acted and who ignored • Attachments and notes on every alert, so people can decide without switching apps SET UP IN MINUTES There's no SDK to install.
