AI-Powered Chrome Extensions for the Web Apps You Can't Replace

There has been a lot of discussion recently about companies using AI to build internal tools that replace SaaS licenses. That is interesting, but it misses a big category of software: the web apps you cannot replace.

Sometimes the constraint is technical. More often, it is not. An insurance company may require you to use its verification portal. A specialty vendor may only accept orders through a clunky ecommerce site. Or a marketplace may be where all of the demand for your product or service lives.

You can build a better internal tool, but you still have to use those sites.

The browser is the integration point

Chrome extensions have always been a way to change the experience of a site you do not control. An extension can read information from a page, add controls to it, and help guide a user through a workflow.

Historically, that was possible but often not practical. You needed to write and maintain custom code for every awkward workflow, and the payoff had to be large enough to justify it.

The latest AI models change that calculation. It is now much easier to build an extension that augments a legacy site, whether that means changing a workflow, extracting information from a page, or adding LLM capabilities directly where people are already working.

Instead of asking someone to copy information from one system into another, you can put the assistance in the browser tab where the work already happens.

A bike search on Facebook Marketplace

I recently had a good excuse to try this out. I was looking for a bike on Facebook Marketplace with a specific set of requirements. The hard part was not finding listings. It was reviewing the photos for each listing to determine whether a bike was actually a fit.

Doing that manually meant opening and reviewing dozens of listings every day. That is exactly the sort of repetitive visual task that an AI model can help with.

So I built a Chrome extension that uses OpenAI to review listing photos and flag the listings that match what I was looking for. Rather than replacing Facebook Marketplace, the extension improves the part of the Marketplace workflow that was taking the most time.

The result is not a fully autonomous bike buyer. It is a faster way to narrow down a large list of listings so I can spend my time looking at the promising ones.

Where this approach works

The Marketplace example is personal, but the pattern applies to business workflows too. Look for web-based processes where a person repeatedly has to review, classify, summarize, or move information before they can make a decision.

A Chrome extension can be a practical place to add help to:

  • an insurer’s required portal
  • a vendor ordering site
  • a marketplace your team depends on
  • an internal legacy application that is difficult to change

The goal is not necessarily to replace the site. It is to remove the tedious steps around it while keeping people in the workflow they already need to use.

Thoughts: Where are the mobile browser extensions?

Last week, I was putting together a Google Chrome extension for one of our clients to help debug Javascript events on a page and I started wondering why don’t we have mobile browser extensions? Unfortunately, there isn’t a simple answer but I think looking towards the desktop can help draw analogies to where we are on mobile now.

So this desktop thing?

Looking back to the desktop, arguably one of the strongest drivers of Firefox’s growth was its rich extension ecosystem. Compared to Internet Explorer, Firefox extensions were easier to develop, leveraged web technologies (XUL, JS, CSS), and offered powerful abstractions out of the box. Because of this, developers began building powerful extensions for Firefox which drove “power user” adoption and ultimately helped spur mainstream adoption. Developers built extensions like Firebug, Greasemonkey, and companies like Rapportive inside the Firefox extension ecosystem. Following Firefox, when Google Chrome launched it debuted its own even simpler extension infrastructure and eventually the Chrome Webstore to help distribute and monetize extensions.

Although largely positive, the extensions developed for Firefox and Chrome weren’t always user friendly. Between redirecting search traffic and surreptitiously injecting ads, “greyhat” extensions negatively impacted user experience while generating revenue without generating value. These “greyhat” extensions fueled what’s colloquially known as Israel’s download valley and ultimately millions of dollars in revenue.

Right so what about mobile?

Compared to the desktop, the landscape on mobile is notably different because of an Apple and Google duopoly with Apple primarily monetizing hardware and Google monetizing search advertising. Additionally, compared to the desktop, Apple and Google have an unprecedented level of control over user devices, all but ensuring that devices will arrive with either Safari or Chrome installed.

I think because of this control, Apple and Google have little incentive to open up Mobile Safari or Mobile Chrome to 3rd party extension developers since doing so would compromise the browser user experience for little gain over the competition. But what about Firefox?

Although Mozilla has released a Firefox build for Android, I think they’ve recognized that trying to win market share away from Chrome on Android is a losing battle and they’re starting to seriously pursue FirefoxOS. Because of this, I don’t think Mozilla will invest in Firefox mobile extensions since it’s clear that there’s more opportunity in powering the OS layer of a user’s phone.

BigCommerce Bulk Coupon Code Importer

A buddy of mine has an eCommerce storefront through BigCommerce, a hosted eCommerce solution. He was looking to run a Gilt City promotion, so he would have to import ~150 coupon codes into BigCommerce.

My friend spent some time looking around for an import codes feature and I would have assumed that a solution like BigCommerce would support a CSV import for coupon codes as well. However, we Googl’ed around a bit and it turns out BigCommerce does not support CSV imports for coupon codes. We stumbled upon this discussion on the BigCommerce forums discussing this shortcoming at length.

On the forum thread, someone had previously developed an iMacros script to automate importing the codes. Unfortunately, I tried using the iMacros script without any success. It looks like BigCommerce has updated the HTML on the page which is breaking the script. Anyway, looking at the iMacro and the opaque syntax I decided it would be easier to whip together a Chrome extension to automate creating coupon codes so decided to move forward with that.

Chrome extensions naturally lend themselves to automating things like this since it’s pretty straightforward to use the background page to maintain any state and hold variables and then use a content script to manipulate the DOM of the page and submit any forms that you need to.

You can grab the extension here http://setfive.com/misc/BigComm Importer.crx you’ll obviously need to be running Google Chrome for it to work.

Also, fork it at https://github.com/adatta02/bigcommerce-coupon-importer

What it does is add a “Bulk Import” button to the “Coupon Codes” page on your BigCommerce site - http://[yourstore].mybigcommerce.com/admin/index.php?ToDo=viewCoupons

If you click that button, a copy of the “add code” form will be displayed along with a textbox. You’ll just need to fill out the form, enter a list of coupon codes you want to create - one per line, and then click “Start Import”.

Your browser will automatically go through and create all your coupon codes. Thats it!

As always, let me know if you run into any issues or have any comments.
