Mental health is a growing concern, yet many people still face challenges accessing care due to costs, location, or stigma. Mental health apps, especially AI-driven ones, are breaking down these barriers, providing affordable, accessible support. With mental health awareness increasing, there’s a rising demand for solutions that allow people to prioritize their well-being on their own terms.
One great example of such a solution is Serena, an AI-powered WhatsApp therapy app that’s transforming how people seek therapy. By integrating therapy into WhatsApp, a platform people already use, Serena offers a convenient and familiar way to access therapeutic conversations. It goes beyond automated responses by creating emotional connections and resilience, providing users with discreet, empathetic care whenever they need it.
This blog will guide you on how you can build a successful therapy app like Serena. From essential features to the AI technology behind it, we’ll explore the steps needed to create an accessible and effective mental health support platform.
WhatsApp Therapy App Serena: An Overview
To give you an idea of Serena’s success, here is an overview of the app, what it does, and why people love using it.
Serena is an AI-powered therapy app available exclusively via WhatsApp, offering immediate, confidential, and affordable mental health support. It uses evidence-based techniques, particularly Cognitive Behavioral Therapy (CBT), to help users manage stress, anxiety, and depression and improve overall well-being. The app is accessible directly through WhatsApp, eliminating the need for users to download a separate app.
Serena’s AI provides 24/7 support, personalizing its guidance over time based on user interactions to create a tailored experience. Users can engage with Serena through both text and voice, choosing the method that best suits them.
One of the app’s major advantages is its accessibility. As it operates within WhatsApp, which has over 2.5 billion monthly active users globally, it seamlessly integrates into users’ daily routines. Its affordability is another key factor; with a flexible credit-based payment system, users can pay per session or opt for unlimited yearly or lifetime access.
Serena is already a leading AI therapist for 2025, with over 5,000 downloads on Google Play and a 4.1-star rating.
WhatsApp’s massive global reach (projected to hit 3.2 billion monthly active users in 2025) means apps like Serena have the potential for vast expansion. Many users report using the app for self-reflection, journaling, emotional support, and as a complement to traditional therapy.

Business and Revenue Model of Serena
To understand how building a WhatsApp therapy app like Serena will be a success, it is important to look at the revenue and business model that it follows.
Business Model of Serena
Focus on Accessibility and Convenience
Serena’s key business driver is its accessibility. By integrating with WhatsApp, a platform most users are already familiar with, Serena eliminates the need for separate apps and complex scheduling. This integration ensures that mental health support is available when needed, without the friction of downloading additional apps or dealing with traditional therapy’s scheduling constraints.
AI-Powered Support
AI plays a central role in Serena’s value proposition. By using AI technology, Serena is able to offer scalable support that isn’t bound by the limitations of human therapists, such as working hours or availability. This allows Serena to serve a wider audience and provide affordable mental health support, both initial and ongoing.
Complementary to Traditional Therapy
Serena is not meant to replace traditional therapy but to enhance it. By offering ongoing, on-demand support, Serena serves individuals who may be seeking supplementary care between therapy sessions or those who cannot access regular therapy due to cost or availability. This model opens up a larger market of users looking for flexible mental wellness solutions.
B2C (Business-to-Consumer) Model
Serena’s primary target is individual users who seek personal mental wellness support. The platform is designed to appeal to those in need of private, accessible emotional support, making it an ideal solution for people managing stress, anxiety, or other mental health concerns.
Revenue Model of Serena
Credit-Based System
Serena operates on a flexible credit-based system. Users can purchase credits to interact with the AI, offering a pay-as-you-go alternative to traditional subscription models. For example, purchasing 25 credits could be priced at $29. This system gives users the freedom to pay only for what they use, making it adaptable to different needs and budgets.
Subscription Options
For those who anticipate frequent use, Serena offers subscription plans. These plans provide unlimited credits for a set period, catering to users who require continuous support. Examples of subscription offerings include unlimited credits for 1 year, priced at $49, and a lifetime unlimited access plan available for a one-time fee, such as $69.
Free Trial
Serena offers new users a free trial that includes a set of credits to help them explore the platform before committing to a paid plan. This trial provides a risk-free way to experience the service and understand its value. Importantly, the free trial credits do not have an expiration date, which encourages users to try the service at their convenience.
Potential for B2B (Business-to-Business) Partnerships
While the primary focus remains on B2C, there is potential for Serena to expand into B2B partnerships. This could involve collaborating with organizations, corporate wellness programs, or employee assistance programs to offer Serena’s services as a mental wellness tool for employees or members.

3. Generative Architecture (Non-Canned Responses)
What sets Serena apart is its generative architecture. Unlike other apps that rely on pre-written or scripted responses, Serena engages users with open-ended, dynamic conversations. This approach allows for a more natural interaction, where users can explore their feelings without being restricted by predetermined answers.
4. Person-Centered Therapy (PCT) Foundation
At the heart of Serena’s design is the Person-Centered Therapy (PCT) approach, based on the principles of empathy, genuineness, and unconditional positive regard. This foundation ensures that Serena creates a non-judgmental, supportive space for users, which is key to fostering trust and emotional safety.
5. 24/7 Availability
Serena offers users around-the-clock access to emotional support. This means that help is always available when needed, allowing users to seek guidance and reflection whenever they encounter challenges instead of waiting for scheduled therapy sessions.
6. Voice Interface
Serena also includes a voice interface, offering users an alternative method of interaction. This feature is particularly beneficial for those who prefer speaking over typing, making it easier for users to express themselves in the way that feels most comfortable.
7. API Integration (Potential)
Serena’s API capabilities open up new possibilities for integration with other platforms and services. This feature allows Serena’s unique AI-powered mental wellness technology to be incorporated into different digital tools, extending its reach and offering benefits to a wider audience.
Serena’s combination of accessibility, empathy, and AI-driven personalization makes it a unique tool in the mental wellness space, providing valuable support for individuals on their mental health journey.
Features to Enhance Serena as a Chat Therapy App
Serena, as a WhatsApp chat therapy app, is already making strides in the market. However, there is always room for growth, and adding new features will give Serena a better edge over its competitors.
If you are looking to build a WhatsApp therapy app like Serena, pay close attention to the following features:
1. Goal Setting and Tracking
To help users stay motivated and focused on their wellness journey, Serena could allow them to set personal goals, such as practicing mindfulness daily or managing anxiety triggers. Serena would periodically check in on progress, offer encouraging words, and suggest relevant resources or exercises based on the user’s goals. A visual progress tracker within the chat interface could be implemented, offering users a sense of accomplishment and motivation as they work toward their goals.
2. Mood Tracking and Analysis
A simple mood-logging feature would enable users to rate their emotional state regularly. Serena could then analyze these logs, identify patterns in mood fluctuations, and offer personalized insights or coping strategies. Presenting the mood data in visual formats, like simple charts, would allow users to track their emotional well-being over time, promoting self-awareness and encouraging proactive mental wellness practices.
3. Personalized Resource Recommendations
Serena could recommend tailored resources, such as articles, videos, meditations, or exercises, based on users’ conversations, mood logs, and goals. These resources would be categorized by topics such as anxiety, stress management, or sleep improvement, allowing users to access content relevant to their needs easily. Users could also have the option to save their favorite resources within the app for future reference.
4. Guided Exercises and Techniques
Serena could integrate short, text-based guided exercises for relaxation, mindfulness, or grounding. Users could receive step-by-step instructions on techniques like deep breathing or progressive muscle relaxation directly within the chat. If technically feasible within WhatsApp or as linked resources, short audio snippets for guided meditations could be added, enhancing the overall experience and offering more diverse ways to manage stress and anxiety.
5. Journaling Prompts
To encourage self-reflection, Serena could provide users with thoughtful prompts designed to explore their thoughts and feelings. The prompts could be categorized by themes like gratitude, self-discovery, or problem-solving, allowing users to focus on areas they find most relevant. Users would be able to record their journal entries within the app or integrate with external journaling apps, giving them a flexible space for personal growth.
6. Safety and Crisis Intervention Features
Serena would include clear protocols for identifying potential crises based on user statements or keywords. In case of any situation, Serena could provide immediate access to emergency contact information, such as suicide helplines, and offer guidance on seeking professional help.

7. Integration with Wearable Devices
With explicit user permission, Serena could integrate with wearable devices like fitness trackers to monitor sleep patterns, heart rate variability, and activity levels. Serena could then offer insights or suggestions based on this data, such as recommending a relaxation exercise before bed if the user’s sleep quality is lower than usual. This integration would enhance the holistic approach to mental wellness, providing a more complete picture of the user’s overall health.
8. Community Support Features
Serena could explore offering safe, moderated peer support groups within the app, with a strong emphasis on privacy and maintaining a positive, supportive environment. Users could share experiences or coping strategies anonymously, allowing for meaningful connections without compromising their privacy. This feature would require careful moderation and clear guidelines to ensure a safe and productive space for users to connect.
9. Progress Summaries and Insights
Periodically, Serena could offer users summaries of their interactions, highlighting key themes, progress toward goals, and any recurring emotional patterns. This feature would provide gentle encouragement, acknowledge the progress made, and offer positive reinforcement. By reflecting on these summaries, users could see how far they’ve come in their mental wellness journey, reinforcing their sense of achievement.
10. Multilingual Support
Expanding language support would help make Serena accessible to a broader audience, allowing more individuals to receive mental wellness support in their native language. Offering multilingual options ensures that users from diverse backgrounds can benefit from the app’s features, fostering inclusivity and accessibility for everyone.
11. Customizable Chat Interface
Serena could allow users to personalize their chat interface, choosing different themes or font sizes to improve comfort and accessibility. This level of customization would empower users to tailor their experience to suit their preferences, making interactions with the app more enjoyable and user-friendly.
Is WhatsApp Ideal to Build Chat Therapy Platforms On?
If you want to build a chat therapy app like Serena, you should know why WhatsApp is the ideal platform for this integration. Take a look:
1. Massive User Base and Familiarity
With over 2.95 billion active users worldwide, WhatsApp is one of the most widely used messaging platforms. This familiarity lowers the barrier to entry, making it easier for individuals to access therapy services without the intimidation of learning a new app or platform.
2. Accessibility and Convenience
WhatsApp offers unmatched accessibility. Users can access therapy services from anywhere and at any time using a platform they already have installed on their devices. WhatsApp supports text, voice, and video communication, giving users the flexibility to choose the mode of interaction that best suits their needs.
3. Real-time Communication
WhatsApp’s ability to facilitate both real-time conversations and asynchronous messaging is a significant advantage for mental health support. Users can communicate at their own pace, allowing them to express themselves freely and seek help when they feel ready.
4. Enhanced Privacy and Security
Security is paramount in mental health therapy, and WhatsApp offers end-to-end encryption, ensuring that all communications between users and therapists remain confidential and secure. Knowing that WhatsApp’s encryption protocols protect their conversations can alleviate concerns about data breaches or privacy violations.
5. Automation and Personalization
The integration of the WhatsApp Business API can significantly improve the administrative side of therapy by automating appointment scheduling, reminders, and follow-ups. This reduces the administrative burden for therapists, allowing them to focus on providing care rather than managing logistics.
6. Multimedia Support
WhatsApp’s multimedia capabilities enhance the therapeutic experience by allowing therapists and users to share documents, worksheets, images, and audio files. Multimedia support is particularly helpful for users with disabilities or those who find non-text communication more effective, making the platform inclusive and versatile.
7. Lower Costs and Increased Reach
One of the most significant benefits of using WhatsApp for chat-based therapy is the cost reduction. There is no need for expensive infrastructure or proprietary apps, making treatment more affordable and accessible, especially for individuals in underserved or remote areas.
Steps to Build a WhatsApp Therapy App Like Serena
Till now, we have established that chat therapy apps like Serena are spearheading the online mental health therapy game. Also, WhatsApp is a suitable and lucrative platform on which to launch your chat therapy app.
Let’s now take a deep dive into the steps that are followed to build a WhatsApp therapy app like Serena:

Factors Affecting the Cost of Building an App like Serena
Here is a breakdown of the factors that might affect the above-mentioned costs of building an app like Serena:
1. AI/NLP Model Sophistication
The heart of any therapy app lies in its ability to understand and respond empathetically. A basic chatbot may be affordable, but to reach Serena-level quality, you’ll need advanced natural language processing (NLP) models trained specifically for emotional context. This means not just larger datasets but also more computing power, longer training cycles, and AI engineers who specialize in mental health dialogue systems. The more nuanced the model, the higher the cost.
2. Mental Health Domain Expertise
AI alone isn’t enough, especially in sensitive areas like mental health. You’ll need licensed therapists and psychologists to help shape the AI’s responses, validate the training data, and define the limits of what the bot should and shouldn’t do. These professionals will also help ensure that the tone, content, and structure of responses meet ethical standards. Their expertise is essential, but it does add significantly to the development budget.
3. WhatsApp Business API Costs and Policies
Using WhatsApp offers convenience, but it comes with unique costs, which include meta charges per conversation based on the type (user-initiated or business-initiated) and country. You’ll also need to comply with their strict policy guidelines. These costs aren’t one-time; they’re operational expenses that will scale as your user base grows. Failing to plan for these recurring fees can quickly derail your budget.
4. Data Privacy within WhatsApp
WhatsApp messages are encrypted, but once data reaches your backend (for processing or storage), it’s your responsibility. Implementing GDPR-compliant storage, access controls, and anonymization methods becomes essential, especially when dealing with mental health data. These privacy safeguards can require specialized developers and security audits, which increase upfront costs and extend your launch timeline.
5. Ethical Considerations and Safety Protocols
You can’t risk your AI bot offering harmful advice or missing a crisis signal. Building logic that can detect red flags like suicidal thoughts or signs of abuse and then appropriately escalate to human intervention or guide users to help lines is a critical (and sensitive) part of the app. Testing these safety protocols thoroughly is both time-consuming and vital for compliance and trust.
6. Voice Interface Integration (if applicable)
If your therapy experience goes beyond text and includes voice-based input or output, costs can climb quickly. You’ll need to integrate speech recognition (ASR) and text-to-speech (TTS) engines, fine-tune them for emotional tone, and test them across various accents and environments. This adds complexity to both backend infrastructure and UX testing.
Monetize a WhatsApp Therapy App Like Serena
On to the most exciting section of this blog: how can you monetize off a WhatsApp therapy app like Serena does? We are breaking it down for you here so you can see for yourself how lucrative building an app like Serena is.
1. Credit-Based System
Users purchase credits to initiate or continue conversations with the AI therapist. This model lets users pay only when they need help, making it flexible and accessible.

- Pros: Users pay for what they value most. Adds flexibility and personalization.
- Cons: It can feel exploitative if essential support is hidden behind paywalls. It needs careful pricing and placement.
5. B2B Partnerships
Partner with employers, universities, or insurance providers to offer Serena as a mental wellness tool for their members. You can charge per seat or offer tiered enterprise packages.
- Pros: Stable revenue streams and potentially large user groups. Strengthens brand credibility.
- Cons: Requires a sales pipeline and possibly a B2B-facing support team. Custom integrations may be necessary.
6. API Licensing (Technology as a Service)
License the underlying AI engine to other mental health platforms, educational tools, or wellness startups. Provide API access for a recurring or usage-based fee.
- Pros: Monetizes core IP without direct user acquisition costs and broadens market reach.
