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.

About

IceChoice

IceChoice helps you slow down and make deliberate decisions instead of reacting on impulse. Break down options into pros and cons, score them using the ICE model (Impact Ɨ Confidence Ɨ Ease), and activate a cool-off timer before finalizing your choice. During the cooling period, decisions stay locked – giving you space to think clearly and avoid rushed judgment. After a week, you review the outcome and track whether your choice worked. Over time, IceChoice builds a personal dataset of your decision quality, helping you understand what actually leads to better results.
