The Problem

Vape Epidemic

82 million active vapers globally struggle with cravings triggered by stress, routines, social settings, or boredom.

Lack of Support

The growing need of quitting and insufficient supply of professionals and tools make traditional smoke intervention services inaccessible and costly.

Frustration ->Relapse Cycle

Traditional quit vaping apps lack personalization and real-time support, leading to relapse when cravings hit. Users feel defeated and doomed after giving in to cravings, creating a negative cycle that's difficult to break.

OUR SOLUTION

OUR SOLUTION

Haven.AI is a proactive, AI-powered chatbot designed to support users in quitting vaping through personalized interventions and practical self-help tools.

Unlike traditional cessation apps that are passive and one-size-fits-all, Haven.AI anticipates high-risk craving moments and delivers timely, tailored support modeled after therapeutic interactions—helping users stay on track before a relapse occurs.

Haven.AI is also the only solution designed to support both cold-turkey quitters and those choosing a gradual reduction approach, meeting users wherever they are in their journey to quit for good.

AI HYPOTHESIS

If Haven.AI proactively initiates personalized and actionable conversations with users to interrupt the craving cycle—with at least 60% precision—then users will be more likely to resist the urge to vape. This not only improves their quality of life and strengthens their trust in the AI, but also drives higher user retention, positive reviews, referrals, and ultimately, revenue growth.

 Feature Highlights

1.Registration & Onboarding Quiz

Empathic, CBT trained chatbot that offers support like a real therapist, adapting to each user’s unique journey based on their profile and real-time emotional state.

Gamify it: earn virtual chips, badges, and milestones by committing to the process.

2. 1 Progress Dashboard (Cold-Turkey Ver.)

After logging vaping events, the user can see their days clear of vaping, money saved, and health score improvement in the dashboard.

2.2 Progress Dashboard (Taping Off Ver.)

Haven.AI is the only solution in the market that caters to users who want to reduce vaping gradually rather than quitting cold-turkey. Instead of days clean, they’ll be shown a trend-line of their daily vape usage.

3. Craving/Vaping Session Logs & Proactive Check-in

Based on user inputs, calendar events, time&location, the bot can learn the user’s craving patterns and offer support before the relapse happens.

4. Self-Help Toolbox

Includes easy breathing exercises, guided meditations, and reflection prompts that users can access anytime they see a craving happening.

User Research Insights

We conducted 18 voice of customer interview with personal users and corporate HR/Wellness professionals. In the 16-question open-ended survey, we investigate their vaping habits, emotional journey, openness to AI powered quitting tools, and willingness to pay.

  • Most vapers either started or continue to vape due to anxiety or stress. The habit has now become automatic.


  • Users expressed a general feeling of being “defeated by the vape” after multiple failed attempts to quit. When the first craving is not managed with care, they fall into the vicious cycle of quit→defeat→vape.

  • Users appreciate the proactive support of an AI chatbot but express concern over excessive notifications, which can feel intrusive. They also value having access to self-guided tools and gamified features that foster a sense of control, agency, and ongoing motivation throughout their quit journey.

AI Model Selection

We chose GPT-4 Turbo as the LLM (over LLaMA 3.1) for Haven AI's chatbot for the following reasons:

  • Faster Response Time – GPT-4 Turbo delivers quicker outputs, which enhances the overall user experience during live interactions.

  • Strong Performance – GPT-4 Turbo generates results that are consistent, empathic, and relevant—crucial for our therapeutic use case.

  • Seamless Integration – GPT-4 Turbo is part of OpenAI's broader developer ecosystem, designed to plug easily into full-stack product workflows. This reduces engineering complexity and enables lean teams to move fast.

AI-Architecture

  • Contextual Prompting
    Haven retrieves the last 10 message pairs to maintain dialogue continuity and constructs the prompt for GPT.

  • Retrieval-Augmented Generation (RAG)
    The prompt is enriched using a RAG pipeline that queries a vector database built on CBT and CounselChatdatasets, enhancing therapeutic relevance and emotional intelligence.

  • Response Generation & Storage
    GPT generates responses based on the enriched prompt. Full conversation history is stored in MongoDB, while only recent messages inform ongoing interactions.

  • Proactive Engagement (APScheduler)
    A scheduled proactive check-in layer uses APScheduler to trigger GPT-based prompts aligned with user preferences, supporting craving tracking and self-reflection.

  • Behavioral Detection (LangChain)
    A LangChain agent detects unreported cravings from natural language and logs them, enabling data-informed personalization without disrupting the user flow.
