I Built a Chrome Extension in 24 Hours With Zero Coding Experience

Perplexity Computer built the extension, the website, the privacy policy, the Chrome Store listing, and walked me through every step. Here’s the whole process.

TL;DR — I used Perplexity Computer to build a full Chrome extension called Niche Intel that pulls real-time competition data, SEO keywords, lyrical analysis, and Google Trends for any music niche. It also built the website (nicheint.com), the privacy policy, the Chrome Store listing copy, and walked me through the entire submission process. Total cost: $5 for the Chrome developer account. Total coding I did: zero. If I can do this, you can do this.

This Is for My Over-35 Crowd

If you’re anything like me, every day you get the feeling that the AI boom is passing you by. You can see it. You know it’s here. You just don’t know how to capitalize. It’s the dot-com boom all over again — only this time you’re old enough to recognize it and young enough to still do something about it.

It keeps me up at night too. But I’m going to tell you: it’s not too late. It’s actually pretty simple. You just have to get out there and start messing with these tools. Stop watching. Start building.

Here’s proof: I built a Chrome extension, a full website, got it published on the Chrome Web Store, and shipped it to users — all in about 24 hours. I have minimal to no coding experience. AI did everything.

The Tool: Niche Intel

Some of you already know about the Music Niche Intel tool I gave away in earlier videos and the newsletter. You could download it to your desktop browser and use it to research any music niche — competition, keywords, trends, all of it.

Well, I finally got it on the Chrome Web Store. It’s live at nicheint.com. Free forever. And I want to walk you through exactly how I built it so you can do the same thing.

WHAT NICHE INTEL DOES

▸ Top YouTube and Spotify competitors for any niche keyword

▸ Lyrical analysis — the most common words in songs for that genre

▸ Musical keywords from Spotify playlists and search data

▸ Google Trends graph showing niche demand over time

▸ Free keywords from DuckDuckGo, Google Suggest, and YouTube Suggest

▸ Clickable genre and mood tags that auto-search

The kicker: all the data comes from 9 free sources. No paid API keys. YouTube Autosuggest, Google Autosuggest, Spotify data, DuckDuckGo, Google Trends. Every tool you’re paying for — VidIQ, TubeBuddy, Keywords Everywhere — they’re all pulling from these same sources through Google’s API. This tool just goes direct.

The Weapon: Perplexity Computer

I don’t hear enough people talking about Perplexity Computer. It’s expensive — around $325/month — but what it does is insane. It’s not ChatGPT. It’s not Claude. It’s a conglomeration of multiple LLMs working in parallel under one system. It uses different tools and different models at the same time to get the job done.

The best part? I can click off and go do something else — even close the browser — and it’s still working in the background. I’d pull it up on my phone at the gym to check progress. I’ve run two or three tasks simultaneously. It just keeps going.

The Process: From Prompt to Chrome Store

Here’s how the whole thing went down, step by step. This isn’t a full tutorial — it’s a walkthrough so you can see that this is doable. I troubleshot everything already so you don’t have to.

STEP 1: THE FIRST PROMPT

I told Perplexity Computer: “I need an all-in-one competition and SEO app that integrates real-time search data for any niche. It should cache every search for 24 hours and use free API keys from every video and music platform.” I wasn’t even sure if it was possible. I just commanded it. And it said: “I’ll start by loading relevant skills and thinking through the architecture.” Then it started building — Python, CSS, JavaScript — and sent me a working dashboard.

STEP 2: DITCH THE API KEYS

It wanted me to use paid API keys. I didn’t want that hassle for the Chrome Store. So I asked: “Is there a way to get accurate data without using API keys?” It found 9 free data sources. YouTube Autosuggest, Google Autosuggest, Spotify Suggest, DuckDuckGo, Google Trends, and more. Problem solved.

STEP 3: FIX ERRORS IN PLAIN ENGLISH

Google Trends threw a 500 error. The chart was too small. The background wasn’t popping up in the browser. Every time something broke, I just told it what happened in plain language: “Here’s my error. This is what I’m getting. It’s not working the way I want.” And it fixed it instantly. Super caveman status. If I can do this, you can do this.

STEP 4: CONVERT TO CHROME EXTENSION

At first I was building a web-based tool. Then I said: “Make it a standalone Chrome extension that works on any computer.” It converted everything, zipped it up, and gave me a downloadable package. I added genres and moods, made them clickable, removed the ones I didn’t want. All through natural language.

STEP 5: BUILD THE WEBSITE

In the same chat, I said: “Build me a homepage to paste into Hostinger.” It built a full PHP website with a support page and privacy policy. I secured nicheint.com, went to Hostinger, chose the PHP option instead of the AI website builder, uploaded the zip to the public_html folder, and the site was live. First time I ever used file manager for anything.

STEP 6: SUBMIT TO CHROME WEB STORE

I’d never been on the Chrome Web Store. Perplexity walked me through every screen. It pre-built all the justifications Chrome asks for — why you need storage permissions, why you need YouTube access, the single-purpose description. When one justification was too long, I said “Hey, this one’s too long” and it said “Here you go, 475 characters, should fit.” I paid $5 for the developer account. Created March 6th. Published March 7th.

The SEO Play Nobody Talks About

Here’s what’s really cool about building free tools. Niche Intel links to AI Guerrilla and to the YouTube channel at the bottom of the site. The Chrome Store listing links to nicheint.com. The website links back to everything. That’s automatic domain authority. Every happy user who installs the extension becomes a backlink, a referral source, and a potential newsletter subscriber — all from a free tool that cost me $5 to publish.

And Grammarly? That’s a Chrome extension. Mostly a Chrome extension. Billion-dollar valuation. Solo founder. Low overhead. I’m not saying Niche Intel is Grammarly — but the model works. You build something useful, give it away free, grow the user base, and the business builds itself around it.

The Lesson: Stop Watching. Start Building.

I have no real coding experience. I’ve never built a PHP website. I’ve never used file manager. I’ve never submitted anything to the Chrome Web Store. And in 24 hours, I had a live Chrome extension pulling real-time data from 9 sources, a custom website, and a published product that people are already using.

The AI revolution is here. Opportunities don’t exist forever. If you’re over 35 and feeling like this thing is passing you by — it’s not. But it will if you keep waiting. Use AI to learn. Use AI to build. Use AI to ship. That’s the whole game now.

The better you talk to it, the better results you’ll get. That’s the only skill you need. Natural language. Your words. Directed at a machine that can build anything. If I can do this, you can do this.
