Create a Chrome extension without coding (plain-English guide for beginners)

Ship your first Chrome extension using AI assistants and copy-paste steps, with no JavaScript required to start, then monetize with hosted Stripe checkout through Payhook.

You do not need a computer science degree to publish a useful Chrome extension. If you can describe an idea in everyday language - “block news sites after 6pm” or “save recipe text from any page” - an AI coding assistant can generate the files, and Chrome lets you try them on your own machine in minutes.

This guide is for non-developers. We skip jargon where possible and focus on what to say, what to click, and when to add payments with Payhook so you never build a billing server.

What you are actually building

A Chrome extension is a small folder on your computer with:

  • A manifest file (Chrome’s instruction sheet)
  • A popup (what users see when they click your icon)
  • Sometimes a background script (rules that run while the extension is installed)

You are not building a website or a mobile app. You are packaging a few files Chrome understands.

What you need before you start

ItemWhy it matters
Google ChromeTo load and test your extension
An AI assistant with coding modeExamples: Claude Code, Cursor, ChatGPT with a project folder
A blank foldere.g. My Focus Helper on your Desktop
30-60 minutesFirst version is usually same-day

You do not need to publish to the Chrome Web Store on day one. Most beginners test privately first.

Step 1 - Describe your idea in one paragraph

Write answers to these questions (copy this template):

Extension name: ___
What it does for the user: ___
When it should run: always / only on certain websites / when user clicks the icon
Free vs paid: what's free forever, what should be "Pro"

Example:

Extension name: Recipe Saver
What it does: When I'm on a recipe blog, one click copies the ingredients list to my notes app format.
When it runs: Only on pages that look like recipes.
Free vs paid: Free for 5 saves per day; Pro for unlimited saves and export to PDF.

That paragraph is your product brief. Paste it into your AI tool in the next step.

Step 2 - Ask the AI to build the extension folder

Open your AI tool in the folder you created. Paste a prompt like this (edit the name and behavior):

Create a Chrome Manifest V3 extension in this folder for non-technical users.

Product brief:
[paste your paragraph here]

Requirements:
- manifest_version 3 only
- A simple popup with one main button and short instructions
- Minimal permissions; explain each permission in a README.txt file
- No payment code yet - leave a visible "Upgrade to Pro" button that does nothing for now
- After you create files, list the exact steps to load it in Chrome at chrome://extensions

Review the files the AI created. You do not need to understand every line - check that you see manifest.json and popup.html.

Step 3 - Load the extension in Chrome

  1. Open Chrome and go to chrome://extensions
  2. Turn on Developer mode (top right)
  3. Click Load unpacked
  4. Select your project folder
  5. Pin the extension icon to the toolbar and click it to test

If something breaks, tell the AI the exact error message from Chrome’s Errors button on the extension card. That loop is how non-developers ship fixes without learning to debug alone.

Step 4 - Charge for Pro without becoming a payments engineer

Chrome no longer offers built-in in-app payments in the Web Store. The beginner-friendly path today is:

  1. Create a Stripe account (see Stripe account setup for extension creators)
  2. Connect Stripe once in the Payhook dashboard
  3. Add Payhook’s hosted upgrade button so checkout opens on a secure page - not inside your popup

Payhook handles Stripe Checkout, payment records, and who paid for Pro so your extension (or your AI assistant) only checks “is this user entitled?” instead of storing cards or webhooks.

Read the full flow: Monetize a browser extension without a payment backend.

Copy-paste prompt for your AI (payments)

Add Payhook to this Chrome extension for Pro unlock.
- Upgrade button in the popup; open hosted Stripe checkout (unlock.payhook.link), not custom card fields
- Gate Pro features with Payhook entitlement checks - no custom license server
- Dashboard: https://dashboard.payhook.link

Common beginner mistakes (and easy fixes)

MistakeFix
Extension does not appearReload at chrome://extensions after each AI change
”Manifest invalid”Ask AI to validate JSON in manifest.json
Paid feature still freeFinish Payhook dashboard product setup and test in Stripe test mode
Afraid of StripeUse test mode first; no real charges until you switch live
