Another week. Another story…
Last week, my nephew asked me to help him study for his history exam.
He needed flashcards for 70+ different topics, and making them manually would have taken forever.
Plus, history makes me sleep.
So I built him an interactive flashcards app in 5 minutes. Sounds too good to be true?
Okay…quick question
What do you do if a problem EMERGES and it’s URGENT?
You use EMERGENT like I did.
Okay bad pun I know. But the app is still pretty cool!
It lets you build actual, working apps just by talking to it.
No code, no technical skills, no ₹50,000 developer courses.
And there are infinite use cases. Calculators. Trackers. Mockups. Portfolios. Flowcharts. Dashboards. I can go on and on…
And like always…I will take you through the process in detail.
But first, let's talk about this week’s chaos in the world of AI
1. CodeRabbit - The Code Reviewer Who Never Gets Tired
Ever had a pull request sit there for days because your senior dev is "too busy" to review it? CodeRabbit flags bugs, gives you detailed feedback and ALSO explains why something might break, suggests cleaner alternatives, and even learns your team's coding style over time. All within minutes
Plus, you can literally argue with it in the comments if you disagree with its suggestions.(try that with your senior)
Perfect for: Developers tired of waiting 3 days for someone to tell them they forgot a semicolon.
2. Rorrim - Your AI Therapist That Actually Listens
This AI journal analyzes your daily voice notes and spots patterns you'd never notice. It's like having a therapist who remembers everything you've ever told them and connects dots across months of conversations.
Send voice memos about your day, and Rorrim organizes them into "reflections" that reveal hidden life patterns, track relationships, and remember important stories.
Game changer for: People who journal but never go back to read what they wrote (so... everyone).
3. Straighty.app - Your Posture Nagging Parent
This one turns your laptop's camera into a posture coach without any wearables.
Real-time monitoring, Pomodoro integration, and smart calibration. It's like having your mom watching you work, but in a good way.
Use case: Anyone whose spine has forgotten what "straight" feels like after years of laptop hunching.
My friend Rohit downloaded three fitness apps last month. All three gave him similar advice: "100 burpees, 50 mountain climbers, plank for 2 minutes."
Rohit is 42, hasn't worked out in 5 years, and has a bad knee since college. Day 1: he couldn't do a single burpee. Day 2: his knee was screaming. Day 3: he deleted all the apps.
The problem: Fitness apps treat everyone like 25-year-old CrossFit enthusiasts with perfect bodies and unlimited time.
Coming back to our flashcards app…it turned out pretty well.
And while my nephew was studying, I started playing around with the app to see if it could do more.
Just described whatever I wanted, and Emergent built it. History lessons, Quizzes, Progress Tracking.
I soon figured that these apps can have AI built right into them.
So they were not just tools, they were smart tools that adapt and learn.
In the next few minutes, I had built:
A QR Code Detector that converts URLs to QRs and vice versa
A Language Learning App that generates practice conversations in Spanish
A Project Management Tools that helps me auto-prioritize tasks
Ready to build your own app in 5 minutes? Lessgo!
Instead of boring theory, let me walk you through building something actually useful.
What we're making: A "Personal Financial Adviser" app that analyzes your spending and gives smart advice.
Step 1: Access the Magic
Go to https://app.emergent.sh
Login through your google account (gives you access to 5 free credits)
Step 2: Describe Your Vision
Tell Emergent exactly what you want. Be specific but conversational:
Step 3: Watch the Magic Happen
Emergent will:
Create the entire app interface
Add input fields for income/expenses
Build categorization logic
Create charts and visualizations
Step 4: Choose your AI Superpowers
Emergent would ask you whether you want to integrate ChatGPT or Claude.
I am proceeding with Claude here. You’d have to add your API Key in the next step. Quick tutorial here.
Step 5: And…we are done!
The app tracks your expenses and helps you make better financial decisions.
Just crunch in the numbers and you have a professional finance expert guiding you on whether that expensive captain america themed watch you want to buy is worth it.
Step 6: Share Your Creation
Click "Share" to get a public link
Anyone can use your app instantly
No downloads, no installations, no hassle
Total build time: Less than 5-10 minutes
Cost: Free (seriously)
Result: A professional-grade financial app with AI coaching
Pro Tips for Building Better Emergent:
Start simple, then iterate: Build basic version first, then add features one by one.
Be conversational: Talk to Emergent like you're explaining to a friend, not writing technical specs.
Use examples: "Make it work like Mint, but for Indian users" is better than explaining from scratch.
Think user experience: Ask Emergent to make it "intuitive for my grandmother to use."
Add personality: "Make the advice sound encouraging, not preachy" creates better user interactions.
Traditional no-code platforms: You drag and drop components, follow templates, fight with limitations.
The speed difference: Building the same finance app on traditional platforms would take days. Emergent does it in minutes.
The intelligence difference: Traditional apps are static. These apps can think, adapt, and provide personalized experiences.
Emergent ftw!
What's something you wish existed but doesn't? An app to solve that annoying daily problem? A tool to make your work easier?
Hit reply and describe it. I'll build it with Emergent and share the link with you. First come, first serve for the 10 best ideas.
It would be fun to see what our community comes up with.
Until next time,
Vaibhav 🙌
P.S. - My nephew aced his history exam using the flashcard app (87%). What are you building?
