Sela Virtual Friend: AI-Powered Psychological Support Bot for Teens by BotLabs Agency

Sela Virtual Friend — Bringing Psychological Support to Teens via AI Chatbot

Project: Sela Virtual Friend (Віртуальний друг Селя)

Client: Ivan Franko International Foundation

Industry: Nonprofit, Child & Youth Psychological Support, Education

Sela Virtual Friend is an innovative Telegram chatbot designed by BotLabs Agency for the Ivan Franko International Foundation. The chatbot acts as a virtual assistant for teenagers, delivering confidential psychological support, educational video content, and interactive experiences via the familiar interface of Telegram. The project seamlessly blends technology, psychology, and Ukrainian culture to address real mental health needs among youth, while promoting the work of Ivan Franko and Lesya Ukrainka. In less than six months, Sela has become a trusted digital companion for thousands of Ukrainian teens, offering help, information, and inspiration in a uniquely accessible way.

Before Sela: Gaps in Accessible, Confidential Youth Support

The Ivan Franko Foundation identified a critical gap: teenagers facing psychological challenges—stress, anxiety, family issues—often lacked accessible, stigma-free support. Existing hotlines and school counselors had several limitations:

• Barriers to Access: Many teens hesitated to phone helplines or attend counseling due to fear of exposure or judgment.
• Limited Engagement: Traditional support lacked interactive, multimedia elements that resonate with digital-native youth.
• Scalability Issues: Human-staffed hotlines couldn’t scale to handle surges in demand, especially during crises.
• Content Gaps: Few resources blended psychological help with Ukrainian cultural education in a format teens enjoy.
• Lack of Automation: No solution allowed for 24/7, personalized, and confidential help via platforms young people already used—like Telegram.

A 2025 UNICEF survey found that 63% of Ukrainian teens preferred digital self-help tools over traditional support, but less than 10% had access to relevant, culturally adapted solutions.

Building a Digital Ally: BotLabs’ Mandate

The Ivan Franko Foundation approached BotLabs Agency with a bold challenge:

"Create a virtual assistant for teens that provides confidential psychological support, delivers expert content, and is as easy to use as texting a friend."

Key requirements:

• Flexible dialog trees for nuanced support scenarios
• All responses authored by psychologists, with multimedia (video, stickers, images)
• Content delivered via iconic Ukrainian characters (Ivan Franko, later Lesya Ukrainka)
• Privacy-first: no retention of personal conversations, strict data protection
• Engaging for teens: friendly persona, stickers, interactive menus
• Admin panel for content management and analytics
• Scalable architecture for thousands of concurrent users
• Fast delivery—launch MVP in 10 weeks, phase two in 4 months

The result needed to be more than a chatbot—it had to become a trusted, always-available companion, blending human warmth with digital convenience.

The Technical Blueprint: How Sela Came to Life

To meet the complex demands of Sela, BotLabs Agency designed a robust, secure, and flexible technical solution. The architecture had to balance usability, privacy, scalability, and content richness.

System Overview:

• Frontend: Telegram bot interface (chat, buttons, stickers, multimedia)
• Backend: Laravel (PHP) API and business logic, Nginx server, MySQL database
• Admin Panel: Secure web app for content/analytics, user management
• Content Delivery: Video, stickers, and images streamed to Telegram clients
• Integration: Google Docs/Sheets for collaborative content prep, Worksection for PM, Miro for UX

Key Features:

• Personalized user onboarding (name, age, gender, for tailored responses)
• Dialog trees with 700+ conversation fragments, 17 support topics
• Multimedia answers: psychologist-vetted videos, actor voiceovers as Franko/Lesya
• Entertainment content: 3D museum tours, curated movies, music, comics
• Crisis help button: instant hotlines and resources
• Confidentiality: no chat history retained by default, user-controlled erasure
• Analytics: depersonalized stats on topic popularity, age/gender trends
• Flexible admin panel: WYSIWYG dialog builder, topic management, content upload

Development Process:

• Phase 1: MVP with Franko persona, 10 topics, 400 dialog fragments
• Phase 2: Lesya Ukrainka persona, 7 more topics, 300+ new fragments, new help features
• Waterfall approach: Fixed scope per phase, clear milestones, weekly client demos

Where Things Got Complicated: Technical & Human Challenges

Developing Sela came with several unique hurdles. BotLabs’ team had to innovate to overcome them:

1. Building Confidentiality by Design

Challenge: Teens needed assurance their conversations were private. Storing chat logs for analytics or debugging was not an option.

Resolution:

• Engineered stateless chat logic—no storage of user queries or sensitive responses.
• Added an instant “Erase Conversation” menu button; also, all session data auto-deletes after inactivity.
• Analytics designed to aggregate only non-personalized events (e.g., topic popularity by age group, not by user).

2. Flexible Dialog Management at Scale

Challenge: Over 700 dialog fragments, each with multimedia, branching options, delays, and triggers.

Resolution:

• Developed a visual admin panel allowing non-technical admins to build, sort, and connect dialog fragments.
• Implemented "fragments" as first-class objects, enabling modular, reusable dialog nodes.
• Content editors could link any fragment to multiple parents/children, supporting complex dialog trees.

3. Persona Animation & Multimedia Delivery

Challenge: Bringing Ivan Franko and Lesya Ukrainka to life with video, stickers, and actor voiceovers within Telegram’s constraints.

Resolution:

• Integrated Telegram’s rich media capabilities (video, stickers, GIFs) to simulate real conversations.
• Content pipeline allowed quick upload and instant deployment of new videos or sticker packs.
• Used in-bot triggers to personalize which persona (Franko/Lesya) delivers answers, based on topic.

4. Scaling for High Concurrency

Challenge: Anticipated spikes in usage during mental health campaigns and school partnerships (up to 10,000 concurrent users).

Resolution:

• Deployed backend on Dockerized VPS, with auto-scaling triggers for CPU/memory thresholds.
• Asynchronous message dispatch to handle bursts of requests without lag.

5. Ensuring Content Safety & Compliance

Challenge: All advice content had to comply with Ukrainian child protection laws and psychological best practices.

Resolution:

• Established review workflow: all new dialogs/videos approved by certified psychologists before publishing.
• Built moderation tools for content creators to flag or remove outdated or inappropriate material.

Why This Worked With BotLabs: Lessons & Uniqueness

The Sela project is a showcase for what’s possible when technology, empathy, and local expertise intersect. Here’s why BotLabs Agency made the difference:

• Rapid Delivery: MVP in 10 weeks, full rollout in 4 months—thanks to our proven waterfall process and tight collaboration with client-side psychologists and content creators.
• Privacy by Design: Every technical decision centered on confidentiality and safety, crucial for youth trust.
• Cultural Adaptation: Integration of iconic Ukrainian personas and literature, making support relatable and educational.
• Flexible Platform: Admin panel empowers the Foundation to expand topics and content without needing developers.
