शैडोइंग अभ्यास: building an app is easy, actually - वीडियो के साथ अंग्रेजी बोलना सीखें

Usually when people talk about building apps on here, and by here I mean like on YouTube, they always advertise it as a method to make money.

Which is a little ironic because YouTube itself wasn't even a profitable app until around 2014.

In fact, most apps nowadays aren't profitable unless they're B2B or business-to-business, meaning you're selling to people who themselves are selling to people.

So I find it kind of funny when people claim

that you can drop out of school or quit your job and just build apps for a living.

because yeah you can build apps for a living

but you'll be building them for a tech company

or a bank at a job or you could just quit your job

and build apps and not make a living

or you could quit your job and make a living

but you won't be building apps I'm not saying it's impossible

to make a living I'm just saying that's not possible and even

if you do get to do all three at the same time be careful what you wish for

so let's just make an app that actually does something useful for fun

because we want to because that's the best way to to learn anyway.

I assume somewhere on your laptop right now is a PDF you haven't read.

Maybe it's a research paper you bookmarked and forgot, but me no want open PDF and read word.

We want stimulating activity.

So how do you actually just sit down and read a PDF fast?

The solution is a technique you've probably seen before, called RSVP, Rapid Serial Visual Presentation, where instead of moving your eyes left to right to read something,

you just have the words flash on screen really fast one

or two words at a time even faster than you could say them out loud.

Normally the fastest a human can read is around 250 words per minute but this technique can get you to read 350,

400 or even 500 words per minute without any previous training.

Now let me just say there are plenty of free apps out there where you can paste in some text

and it will flash each word on the screen one at a time for you

but so far I haven't found anything that's both free and works on PDFs.

So how about we build one?

And let's call it Read Faster, because I was going to make a creative name, but then I realized half of the most downloaded apps on Google Play don't have creative names.

So why bother?

Now that you have the idea for the app and the name, you might feel a little underprepared.

But many tech startups, in order to become truly billion-dollar companies, go through a long period of aggressively spending money from outside investors to grow.

During the losing money stage, these startups are called pre-profit.

Some tech startups don't even charge money yet, which makes them pre-revenue.

Some are still working on the actual app and haven't released it yet, which makes them pre-launch.

Some haven't even started working on the app and just have a PowerPoint presentation on what the app would do.

This is known as pre-product.

Lastly, some startups don't even know what the app would be about, just that it's going to use AI.

This is known as pre-idea and it's about where 99% of startups are, so the fact that you have an idea already puts you way ahead.

Now even though you might want to get to blindly vibe coding the app straight away, the components of an app are actually pretty easy to understand, so I think you might as well learn them.

First, you need a UI or user interface, also known as a front end.

This is all of the buttons and screens that the user will see and interact with on the app.

The UI for your app will be slightly different when it's on the web versus iOS versus Android.

Next, you may need a server-side framework, also known as a backend.

This is what will manage all the data for a user

so that they can make an account or use the same app across multiple devices.

For example, let's say you make an app like Tinder

that requires people to make an account and five people download your app.

In order for them to sign in, you need some type of server that, somewhere, keeps track of all their passwords and data and who they matched with and what their current Tinder ELO is.

Every time someone logs in, they have to talk to the server first.

If you want this to happen, you need to code a backend.

But if it's just a game like Flappy Bird, where no one has an account, and there's no leaderboard, and the only data it tracks is the highest score each person has on their phone, then you don't need to make a backend.

Flappy Bird would be considered an entirely front-end app.

The last thing is packaging and publishing.

This just means combining all the code into a format that a phone or web browser can understand.

and then you just publish to the App Store or Google Play, or it could even just run on a website.

Now that we at least understand what's happening, we can vibe code the app.

Well, maybe not you, maybe you're an actual coder, but I will vibe code using Bolt, which is just a free option that used to be popular, but may or may not be completely obsolete in two months.

Never mind, it's already obsolete.

Okay, so instead we're going to use Google AI Studio to build the app.

You can write a prompt here for the app, which obviously I'm going to ask Claude to write.

I'm going to give it the app requirements, and then the framework I want it to use, and then the single design requirement.

A framework is just a pre-written set of tools, libraries, and other stuff that just makes your app logic standardized, easier to code, more secure, and a lot more reliable.

The technology we'll use is the free Kotlin multi-platform made by JetBrains.

You may have heard the Kotlin programming language before, but this is a technology that's multi-platform, meaning it allows you to write code once and deploy it to Android,

iOS, desktop, to a server, and the web just from one code base.

In a multi-platform architecture, your app's divided into two pieces.

The first is the shared logic.

For us, that's the logic for the program to read the PDF, to sequence the words, to calculate the words per minute and the timing of each word.

Basically, everything that is done behind the scenes to flash the words on the screen.

That code is written once in Kotlin and runs on every platform.

So you only have to maintain one thing, just one code base.

The second piece is the UI.

With Compose Multi-Platform, JetBrains' declarative UI framework, which works across Android, iOS, desktop, and web, you write the UI once and it renders natively everywhere.

Meaning everywhere, the app can run smoothly and without any lag.

The recommended way to set this up is to download IntelliJ IDEA, which is a coding workspace.

This is where you'll be writing all your code.

Then you just go to plugins and download the one called Kotlin Multiplatform.

After this, the template and starter files will already be there for you.

So you already have the skeleton.

Now you just have to code.

And if you've never written Kotlin before, imagine Java, but about 40% less code.

You can code an app just once and you could ship it out to run cleanly on any platform.

If you're really getting into app development, you probably want to try this out, so check the description.

By now, Google AI Studio should have fully generated the app

and now you could preview it and you could also look at all the code.

Once we've previewed it and tried it and we see that it works, the next step is to thoroughly test the app across various cases,

various inputs, and all kinds of button presses to make sure that there are no bugs.

After completely ignoring that step, we move on to deployment.

Well, okay, you're not supposed to completely ignore testing, but personally, I feel like playing around with the preview you get is enough testing.

Now it's time to deploy, which means put the app out on the internet for anyone to use slash install.

In our case, we'll deploy it to the web

because it costs money to get your app on the App Store or Google Play, and I know you don't want to do that.

Now, you could deploy straight to Google Cloud.

That's what Google wants you to do.

That's why it's the only option when you click the big publish button.

And technically, Google does give out $300 of free Google Cloud credit to everyone.

So you technically don't have to pay, but still requires you to put in your credit card information.

And I know you don't want to do that.

100

Anyway, we're not going to deploy with Google Cloud.

101

We're going to deploy using Vercel, which is free.

102

Vercel basically hosts the app on the web so

103

that Someone across the world can type in the link to your app and access it online and use it.

104

Before that, one thing you might want to do first is go to the code tab here, and then on the right, you can download all the code as a zip file in

105

case you want to work on it later inside an actual code editor and not Google AI Studio.

106

But if you don't feel like downloading the code, you don't have to.

107

Now to deploy with Vercel, we first need to use GitHub as a middleman.

108

Just hit the settings button in the top right and keep scrolling right until you get to GitHub.

109

Now, just sync your code to GitHub.

110

Make a GitHub account if you need to.

111

It probably takes under a minute, like I made a new account just for this.

112

And then you follow the steps to transfer your code from Google AI Studio over to GitHub, which should be quick.

113

Once all that is finished, you now have a GitHub repository that is storing all your code for the app.

114

Now search up Vercel, make an account, and then click Start Deploying.

115

Copy your link to your GitHub repository and paste it here.

116

And then follow all the steps after that until eventually you can click the final button and deploy your app.

117

Pretty soon it'll finish deploying and now you plus anyone else can access and use the app on the web.

118

This app doesn't actually have a backend.

119

So it doesn't store any user data.

120

It doesn't need you to log in.

121

And it would have done it using Firebase, which is just a Google-owned service that'll take care of everything you need for databases,

122

authentication, cloud functions, sending notifications, stuff like that.

123

All you have to do is click yes when it asks you if you want to use Firebase.

124

And now you have a backend.

125

Anyway, there's no steps left, besides maybe improving your app if you want to.

126

But other than that, it's done.

127

Use it once and forget about it.

128

Tell your friends who don't care about it.

129

Add it to your resume.

130

They'll get auto rejected by the AI screening system anyway, whatever you want to do with it.

131

You can even LARP as an actual software developer.

132

I know I will.

इस वीडियो से अभ्यास कैसे करें

पहले बिना बोले पूरा वीडियो एक बार सुनें और जो शब्द नहीं आते उन्हें लिख लें।
0.75× गति से शुरू करें, एक-एक वाक्य की शैडोइंग करें, और सहज लगने पर सामान्य गति पर लौटें।
अपनी आवाज़ रिकॉर्ड करें और मूल से तुलना करें, ख़ासकर vibe, preview, publish जैसे शब्दों पर ध्यान दें।

शैडोइंग तकनीक क्या है?

शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
