Using AI tools to create “Fraudly” in 2 days

I, along with my teammates, Amartya Jha, Annem Saad, Krishna Mittal, and Siddhant Singh, participated in the AI Buildathon by the Masters Union. The objective of the Buildathon was to create a real AI product solving a real-world problem. And in 2 days, we went from an idea to a working prototype called “Fraudly”, an AI-powered app designed to fight digital fraud among teenagers.












Teenagers are among the most vulnerable to digital fraud — yet almost no engaging solutions exist for them. With UPI fraud rising sharply and millions of teens coming online every year, the gap was obvious. What if we could teach fraud awareness by letting users experience scams safely? Thus, “Fraudly” was born.


The App simulates real-world scam scenarios (UPI, WhatsApp, SMS), lets users swipe to decide: scam or legit, uses AI to explain red flags instantly, and adapts difficulty based on user behavior. Using tools like Replit and Claude, creating a functional app was possible in no time.


The Buildathon followed a fast-paced, startup-like structure. Day 1 was spent in problem identification using AI-assisted research, design thinking workshops, and MVP development. Day 2 was used for prototype refinement, pitch deck creation, demo video production, and final presentation to industry leaders. 


Key Learnings from the Buildathon - 


1. Design Thinking - The team experienced firsthand that design thinking is about - 

Empathise → Understand real user pain

Define → Narrow the problem clearly

Ideate → Explore bold solutions

Prototype → Build fast, imperfect versions

Test → Learn, refine, repeat


2. The Rise of AI Workflows (Hello, n8n)

Tools like n8n introduced a new paradigm:

Creating memory for AI systems

Designing end-to-end workflows

Connecting multiple AI tools seamlessly


3. The Modern Builder Stack - The team was exposed to a powerful toolkit:

Dribbble → UI inspiration

Stitch → Rapid interface creation

Flutter → App testing & deployment

Swift → Native iOS development


The Buildathon proved something powerful: With today’s AI tools, barriers to building products have come down. You only need the willingness to build, test, and learn faster than everyone else.

IIT Delhi Robotics Festival - Tryst 2026

Long Post Alert!  IIT Delhi Tryst 2026   https://tryst-iitdelhi.org  I had the opportunity to visit IIT Delhi for the Annual Robotics festival TRYST 2026, and didn't miss it even though it was right in the middle of my final exams. A few days' break in the exam schedule due to Holi helped as well. Though I only had a 3-hour window, I got the vibe: the participants, the energy, the displays, the seminars, and the competitions. I liked the following:  1. The ISRO Exhibition, with models of Chandrayaan-3 (1:15), GSLV Mk III (1:20) and PSLV (1:20). Chandrayaan-3 had achieved India's historic soft landing on the Moon's South Pole on August 23, 2023, making India the first nation to do so and the fourth country overall to land on the Moon. The mission successfully deployed the Vikram lander and Pragyan rover, completing all its scientific objectives, and demonstrating India's advanced space capabilities. The GSLV Mk III, now redesignated as LVM3 (Launch Vehicle Mark-3), i...

Statics of a human arm

Let's talk about the statics of a human arm holding a weight. Let's try to calculate how many Newtons of Force is the biceps tendon carrying, and what is the moment in the shoulder joint? We assume that a person of 100 kg is holding a dumbbell weighing 10 kg.  Thus, weight of the upper arm = approx 4% of body weight = 4 kg,  and weight of the fore arm = approx 3% of body weight = 3 kg.  We take the length of the fore arm = 30 cm. Also, for keeping calculations simple, we take g = 10m/s2. Cutting the system free F w1  = 40 N, F w2  = 30 N, F wd  = 100 N α  =  10 ° d 1  = 5 cm, d 2  = 15 cm, d 3  = 30 cm We can calculate  Force on the Bicep, F B  = 172.62 N Shoulder Moment, M A  = 34.5 Nm This is fun!

Robotic Hand Assist for Rehab - Part 2 - The Genesis

Image
The Inspiration Behind My Robo Hand Assist for Rehab Project! Some incidents have a deep impact on you. In December 2025, someone very close to me met with a horrible accident, suffered multiple injuries in the hands, legs, and hips, had to go through multiple surgeries, a long period in the hospital, followed by a long period of recovery. Among the injuries, one was particularly brutal, not because it was life-threatening, but because it took away control. He suffered a radial nerve injury, a condition that affects the ability to extend the wrist and fingers. In simple terms, the hand loses its ability to open and lift. This leads to something known as “wrist drop”, where the hand is unable to perform even the most basic actions. Holding a bottle. Picking up a pen. Shaking someone’s hand.Movements we never think twice about suddenly become impossible. What followed was a series of complex medical procedures - fracture fixation, nerve repair, and eventually a tendon transfer surgery. F...
