# An Overview of Tools and Technologies for Anxiety and Depression Management Using AI
## 5 Evaluation of AI Tools--Case Studies
### Practical Impact of AI Tools on Users' Daily Lives  
The widespread availability and use of artificial intelligence tools has brought about a number of changes in the daily lives of users. Many people can now choose the right tool for them and in time use it to improve their mental health. One of the main advantages of these tools is their accessibility and easy use [113]. Chatbots and apps provide users with instant access to support resources, regardless of time and location. Users can leverage these tools discreetly and anonymously, thus overcoming barriers related to stigma and reluctance to seek help. Research has shown that AI-based interventions offer effective symptom relief and can enhance users' sense of empowerment and self-efficacy in managing mental health challenges [114]. Furthermore, AI tools leverage advanced algorithms to personalize interventions based on users' unique needs and preferences. Through machine learning techniques, these tools can analyze vast amounts of data to tailor interventions to individual user profiles. For example, wearable devices such as smartwatches monitor physiological signals such as heart rate variability and sleep patterns to provide personalized information about users' stress levels and emotional well-being [115]. By offering personalized recommendations and adaptive feedback, AI tools facilitate a more differentiated and targeted approach to managing anxiety and depression. Therefore, even unconsciously, the user can carry out his daily tasks, receiving recordings of his emotions and body functions, for future management. These data can then be used by a professional to support the diagnosis and treatment process. AI apps and tools essentially help both users and health professionals [116].  
In addition, the use of artificial intelligence tools may be a first step in symptom management or prevention. The user understands himself better and adopts positive practices and exercises that improve his daily life. In other words, he learns to take care of himself. At the same time, the use of such tools democratizes access to health since users can use services and receive personalized guidance at low cost. The same applies to people living in remote areas, whose access to health facilities is lacking. Using artificial intelligence tools, people with symptoms of anxiety and depression can contact trained chatbots or health care professionals, sending the data from the app in real time for an initial assessment and immediate support [32].  
However, despite their potential benefits, AI tools also present some limitations and challenges. One notable concern is the lack of human interaction and empathy inherent in automated interventions. While chatbots and apps can simulate conversations and provide support, they may lack the depth of understanding and emotional resonance that human therapists offer. Research shows that the quality of therapeutic alliance and relationship is crucial in mental health interventions, and the absence of genuine human connection can limit the effectiveness of AI-based approaches [27]. Beyond that, it is possible that people with anxiety and depression disorders will postpone visiting a specialist or substitute health services for those of apps. Despite the benefits these tools can offer, their potential to replace critical and synthetic thinking or the empathy that a human and professional can offer has not yet been proven. Finally, the user may underestimate his symptomatology based on the evaluation of the application, resulting in not receiving treatment in time [116]. Overall, users should use such applications and tools as an adjunct and not equate them with the diagnosis and treatment that a professional would offer.
