Why I Built a Chrome Extension to Save E-Commerce Sellers Hours on Pinterest Marketing

My partner runs an online store. Like many e-commerce business owners, she uses Pinterest for e-commerce traffic and product discovery. Pinterest is one of the best visual search engines for shopping inspiration, but posting products manually is exhausting.

Every time she wanted to promote products, the process looked like this:

• Copy the product title
• Copy or retype the product description
• Upload the product image
• Paste the product link into Pinterest

If you’ve ever asked yourself:
“Why does posting products to Pinterest take so long?”
“Is there a Chrome extension that automates Pinterest pin creation for e-commerce?”
— you already know the frustration.

Doing this for hundreds (or thousands) of products isn’t just time-consuming, it’s a barrier to growth.

The Spark of an Idea

Watching this repetitive process gave me the idea:
What if a browser extension could:

• Scrape product data (title, description, image, link) directly from a product page
• Create a complete Pinterest pin in seconds
• Let sellers post instantly to their Pinterest boards

That’s how Product Pinner was born, a Chrome extension to make Pinterest marketing for online stores quick, easy, and scalable.

The Journey of Building Product Pinner

I didn’t just want to hack together a side project. I wanted a real, polished tool that:

• Worked across platforms (Shopify, WooCommerce, Magento, Squarespace)
• Respected privacy and data handling rules
• Could be distributed through the Chrome Web Store
• Had a clear monetisation model (Free vs Pro)

To build it, I tested AWS’s new AI coding agent, Kiro. It handled the technical scaffolding:

• Creating the Chrome Manifest V3 boilerplate
• Wiring up TypeScript + React
• Integrating Pinterest’s OAuth 2.0 authentication
• Implementing usage tracking for Free vs Pro tiers

But I still had to step in for the tough parts:

• Navigating the Pinterest API approval process
• Writing a compliant privacy policy for Chrome extensions
• Designing the Stripe licensing system to sell extensions on my new site, ExtensionsPro by Team Handsome

Free vs Pro: A Simple Monetisation Model

A lot of SaaS tools for Pinterest are expensive subscriptions. I wanted something simple and fair:

• 🆓 Free tier: 2 pins per day, enough to try it out.
• ⭐ Pro license: unlimited pins with a one-time purchase. No recurring subscription.

For sellers searching “Is there a Pinterest automation tool without monthly fees?” — Product Pinner is designed for you.

Why Pinterest Matters for E-Commerce

Pinterest isn’t just another social network. It’s where people go to plan purchases and discover products. A well-optimized product pin can keep driving traffic for months, even years.

For example:

• A Shopify store with 500 products would take weeks to post manually.
• With Product Pinner, those same products can be pinned in hours.

This is why tools that automate Pinterest pins for e-commerce can be game changers.

Privacy and Trust

One of my guiding principles was local-first architecture. That means:

• All data (tokens, usage counts, settings) are stored locally in Chrome, not on my servers.
• No personal information is collected.
• Pinterest access can be revoked at any time.

For anyone asking “Is there a secure Chrome extension for posting to Pinterest?” — that’s exactly what I built Product Pinner to be.

From Frustration to Solution

What started as one person’s frustration turned into a broader solution. Along the way, I:

• Tested AI coding agents like AWS Kiro
• Learned how to navigate API approvals and compliance
• Built a licensing platform to sell extensions (ExtensionsPro)
• Launched a product that solves a real-world problem for e-commerce marketers

Conclusion

If you’ve ever been frustrated by the time it takes to post products to Pinterest, you’re not alone. That frustration is what drove me to build Product Pinner, a Chrome extension that helps e-commerce sellers create Pinterest pins in seconds.

• Free tier: 2 pins/day
• Pro license: unlimited pins with a one-time purchase

You can now find Product Pinner at ExtensionsPro by Team Handsome or on the Chrome Store by search for Pinterest Product Pinner.
