Introduction: A Light in the Dark
Mental health is one of the most critical yet underserved areas of modern life. In a fast-paced digital world, many individuals struggle to find someone who will simply listen—someone who understands, comforts, and uplifts.
That's where VibeBuddy comes in.
Developed as a Capstone project on Kaggle, VibeBuddy: A Light in the Dark, A Friend When You Need One is a GenAI-powered virtual companion designed to provide emotionally intelligent, multilingual, and creative support to users. Whether it's through empathetic conversations, uplifting poems, comforting stories, or cheerful audio responses, VibeBuddy is built to make you feel heard and cared for.
The Problem: A Lack of Accessible Emotional Support
- Are you frustrated from conflicts at your home?
Family disagreements, misunderstandings, or the pressure of responsibilities can leave you feeling drained and unheard. - Does your manager give you mood swings, and you're unable to control your anger?
Workplace stress and difficult interactions can trigger emotional reactions that are hard to manage, especially when you have to bottle it all up. - Do you ever cry in the shower so no one sees?
Because sometimes, that's the only quiet moment you get to feel what you're feeling. - Are you tired of pretending to be okay when you're not?
Whether it's at work, at home, or with friends—wearing a mask every day is emotionally draining. - Have you ever stared at your phone hoping someone would check in... but no one does?
Loneliness in the digital age is louder than ever. - Is your mind overloaded with "what-ifs" and "should-haves"?
Overthinking, guilt, and self-doubt often echo louder when there's no one to help untangle your thoughts. - Struggling with a breakup, loss, or personal failure?
The pain is real—but you're expected to "move on" like nothing happened.
Despite growing awareness, emotional support remains out of reach for many people around the world. Life doesn't come with a manual, and navigating its ups and downs without someone to lean on can be incredibly hard.
Yet, seeking help often comes with its own obstacles:
- Long waiting times for therapists.
- High costs for consultations.
- Social stigma around mental health.
- Fear of judgment when opening up.
- Feeling like a burden to friends and family.
In moments like these, what we truly need is someone who listens, someone who cares, and someone who understands without judging—even if it's just a voice on the other end.
VibeBuddy was born out of this need—a gentle presence in your digital world, always there when you need a friend, a laugh, a warm word, or just someone who gets it.

We have used below code for better understanding of document understanding:
from google import genai
from google.genai import types
client = genai.Client(api_key=GOOGLE_API_KEY)
human_emotion_data = client.files.upload(file='/kaggle/input/humanemotions/The-Book-of-Human-Emotions-An-Encyclopedia.pdf')
vibebuddy_instruction_config = types.GenerateContentConfig(
temperature=0.1,
)
vibebuddy_instruction = client.models.generate_content(
model="gemini-2.0-flash",
config=vibebuddy_instruction_config,
contents=["""Read and understand the pdf on Human Emotions and
based on that generate instuctions for bot...""", human_emotion_data],
)
print(vibebuddy_instruction.text)
Here we have used a pdf which is based on human emotions, ai will read the pdf and create instruction for our bot. google-genai==1.7.0 is used here.
