24/7 support means the chatbot is available anytime, day or night. This around-the-clock availability is a huge advantage, users can get immediate help or a listening ear during “moments of crisis”, without waiting for an appointment or feeling uncomfortable to reach out to a friend.

It makes mental health or emotional support more accessible handling high volumes simultaneously — specially for people in crisis at odd hours. The main caveat is that being always available doesn’t equate to being always sufficient, users might become too reliant on a chatbot that cannot (and shouldn’t) fully replace professional care.

Pros

Immediate help in moments of need

The biggest advantage of 24/7 availability is that users can receive support exactly when they need it, not hours or days later.

Emotional crisis are unpredictable; having an always on chatbot means if a user feels panicked, depressed, lonely or suicidal in the middle of the night, they can get immediate coping assistance and resources when traditional services are out of reach. This instant responsiveness can be lifesaving.

For example, Woebot reported that 79% of its interactions occur outside traditional clinic hours (5 PM–9 AM), highlighting how AI chatbots fill a crucial gap when human therapists are unavailable.

Consistency of support

A chatbot doesn’t get tired, doesn’t have off days, and won’t cut a session short because time’s up. Users can chat at length if needed, or even multiple times a day. This consistency can be comforting.

For example, if someone is going through a breakup, they might check in with the bot every night for a week for reassurance. The bot will reliably respond each time with the same patience. Such continuous support can help reinforce positive behavioural changes because the bot is always ready to guide the user, which can improve outcomes overtime.
