Why AI Mental Care Apps Are the Next Big Thing in Side Hustles

In a world that’s more connected, anxious, and self-aware than ever before, mental wellness is no longer just a personal goal. It’s a booming business. And if you’re looking for your next side hustle, AI-powered mental care apps might be one of the most underestimated goldmines on the horizon.

What Are AI Mental Care Apps?

AI mental care apps combine machine learning, natural language processing, and mental health frameworks (like CBT or mindfulness) to create tools that can help users manage anxiety, stress, depression, burnout, or loneliness often through chatbot-like interfaces, mood trackers, journaling systems, or personalized advice.

Unlike traditional therapy apps that connect you to real therapists (like BetterHelp or Talkspace), these use AI to simulate conversations or automate wellness tasks, making them much easier to scale.

Is There a Market?

Absolutely and it’s growing fast.

  • According to Grand View Research, the global mental wellness market size was valued at $131 billion in 2023, with AI solutions showing the fastest growth.
  • Chatbot therapy and self-guided wellness tools have seen a spike in downloads, especially post-COVID when therapist waitlists became long and mental health awareness surged.
  • Gen Z and Millennials are particularly open to digital self-care routines, with many already using apps like Calm, Woebot, or even Replika.
