How to Build a Custom Chrome Extension for Cold Outreach Using AI
Here's how we make custom Google Chrome extensions for outreach to prospects.
Now, a little bit of background, my name is John. I run 5Four Digital. We craft profitable brands and websites that drive business growth for businesses. That's what we do. That's in the business that we're in.

And so, what we did was we created a custom Chrome extension called Hero Insight. And what Hero Insight does is it gives you a first impression audit for any homepage. So, it'll give you clarity, audience signals, CTA direction, and trust. So, we've broken it down into four categories of what it evaluates. It evaluates the message clarity, is the headline concrete? Is it outcome-driven? We look at the audience signal. Does the hero communicate who it's for, or could it be talking to anyone else? And then we look at CTA direction, make sure it's clear, and trust presence. Those are the four criteria that we created. You can use this Chrome extension, it's free. Add it to a website, and we use this for prospecting.
It's really great because if we want to reach out to a prospect, we just run this Hero Insight on their website, and it gives us the results. So, here I am on range.com. Nothing against range.com. I just chose this website randomly, and I chose to run the Hero Insight Chrome extension, and these were the results it provided. So, it will give you an overview. As you can see, it's given us the breakdown, and then it'll give you the four criteria and what's missing, it needs work, if it's good, and it'll provide you with that feedback. Then you can also copy these results into an LLM like ChatGPT or Claude, which this was built in, to give you a hero image or hero area copy that's going to work really well to counteract this that you can then run again to see if it works better.

So, this is a really great tool for breaking the ice with a prospect. It's also great for doing cold outreach because you're providing value up front to a potential partner that they otherwise wouldn't get. So, you can actually download this. Just go to Chrome Web Store, hit Hero Insight by 5Four, and you can access that and be able to use this Chrome extension anytime you like. So, now, if you're thinking about building your own Chrome extension, I recommend using Claude. It's going to help you develop it, develop your ideas, and I actually have a questionnaire that I'm going to share with you. You can actually get it in the comments as well, but you can access that pretty easily.
So, these are the questions you want to ask. It's broken down into essentially five different areas. You have the why, you have the what, you have the how, you have the build, and you have the launch. So, the why is setting up the problem, right? You're going to ask, "Well, what repetitive task do I need to fix in outreach? What does my current workflow look like?" We came up with this idea because we were brainstorming with an LLM saying, "We want to do more reports and more things for clients that'll be low-hanging fruit, something quick and easy that we can provide them value up front."

And so, it came up with this Hero Insight process that we finally delved into and created an extension for. What you can all do in Claude as well. You just walk through the process just like this. So, you can actually use this form verbatim. Add this into your LLM and add the caveat saying, "Hey, these are some questions that I just answered. Can you help me come up with some ideas for Chrome extensions we can create to facilitate this?" And so, you want to go through these questions, "How much time does the manual process cost you? What exactly should the extension do when someone clicks it?"
So, these are questions that are really going to help you develop the idea for that extension. So, again, you can check this out, Hero Insight by 5Four. You can have this run on any website that you like, and if you have any questions, drop them in the comment. I'm going to try to make more videos like this on a day-to-day, so you have more value that I have more value that I can provide to you guys. And if there's any questions that you have regarding web design, branding, development, setting up workflows for your AI, AI tools, all that good stuff, hit me up. I'm here to help.
