KM3NeT is a multi-purpose cubic-kilometer neutrino observatory under construction in two different sites of the Mediterranean Sea. It consists of ORCA and ARCA (for Oscillation and Astroparticle Research with Cosmics in the Abyss, respectively) telescopes, currently taking data with the first set of detection lines in operation. Although having different primary goals, both detectors can be used for neutrino astronomy over a wide energy range, from a few tens of MeVs to PeV energies. In view of the growing field of time-domain astronomy, it is crucial to be able to promptly identify neutrino candidates. Real-time searches can significantly increase the discovery potential of transient cosmic accelerators and refine the pointing directions in the case of poorly localized triggers, such as gravitational waves. KM3NeT is implementing a fast online reconstruction and classification system for both detectors. Neutrino alerts will be sent nearly real-time to the astronomy community and they will consist of both self-triggered events of interest, such as multiplets and VHE events, and the results of online search for time/space coincidence given external electromagnetic and multi-messenger triggers. This poster presents KM3NeT online multi-messenger activities, the alert format, alert definitions, and the expected timeline of issuing public alerts.
