How ChatGPT is Changing Custom Coding in HubSpot (and Beyond) With Connor Jeffers

Let’s be real for a second. Most marketers and business leaders hear “coding” and immediately break into a sweat. For years, coding has felt like a gated community for people who speak a language the rest of us don’t. But what if I told you those walls are coming down?

In this conversation with Connor Jeffers, founder and CEO of Aptitude 8, we pulled back the curtain on how ChatGPT, specifically with its code interpreter, is changing the way marketers, developers, and businesses approach custom coding inside HubSpot and beyond. And trust me, this is not just about writing blog posts faster. This is about giving you access to coding power that used to take hours, teams, or even entire budgets to accomplish.

So, let’s dig in.

What Is ChatGPT as a Coding Assistant?

Before we get too far, let’s clear the air. ChatGPT is a large language model from OpenAI. Most people know it for content, research, or idea generation. But that’s just scratching the surface. With the addition of the code interpreter (a feature in GPT-4 for $20 a month), ChatGPT can now:

  • Understand existing code.

  • Edit and rewrite code in different languages.

  • Write new code to solve problems.

  • Run Python scripts against files you upload.

Imagine combining a chat tool with a junior developer who works at lightning speed and actually explains their process as they go. That’s what we’re dealing with.

What Is the Code Interpreter and Why Does It Matter?

The “code interpreter” might sound intimidating, but here’s the simple version: it lets ChatGPT use code to process and deliver your requests. You can upload a CSV, ask it to clean your data, visualize trends, or even reformat reports into charts styled with your brand colors.

Here’s the kicker: it doesn’t just spit out an answer. It shows its work. If it runs into a hiccup, like inconsistent date formats, it fixes it automatically and keeps going. That’s where the magic lives.

For marketers and HubSpot users, that means no more crying over pivot tables in Excel or getting stuck in the weeds of data cleanup. Instead, you upload, describe what you want, and let ChatGPT handle the heavy lifting.

What Are the Benefits of ChatGPT for Custom Coding in HubSpot?

Let’s talk practical benefits. Because theory is great, but you want to know what this looks like in the real world.

  • Accessibility: You don’t need to know Python from a python. ChatGPT lowers the barrier to entry so anyone can work with data or light coding tasks.

  • Speed: Tasks that once took hours or even days can be done in minutes. Upload, describe, adjust. Done.

  • Collaboration: Non-technical marketers can articulate ideas in plain English, and ChatGPT translates them into code that developers can refine. That’s a game-changer for teamwork.

  • Innovation: By reducing the cost of experimentation, you can actually test those “what if we tried…” ideas without slowing down the entire team.

This isn’t about replacing developers. It’s about freeing them (and you) from the repetitive stuff so you can focus on strategy, creativity, and execution.

What Are the Challenges and Limitations?

Now, before you run off and try to build your entire CRM on ChatGPT, let’s keep it grounded. There are limitations:

  • Languages: Right now, it mainly supports Python, JavaScript, and Ruby. That may expand, but for now it’s not a one-size-fits-all solution.

  • Accuracy: Remember, ChatGPT is a “guessing machine.” It produces the most likely answer, not necessarily the right one. Always test, verify, and validate before rolling it out in production.

  • Privacy and Security: Anything you upload becomes part of ChatGPT’s data universe. Don’t paste in sensitive or private customer data unless you’re using a secure, enterprise solution.

Limitations aren’t deal-breakers, though. They’re guardrails. If you treat ChatGPT as a first-draft generator or coding partner rather than an all-knowing oracle, you’ll unlock massive value.

How Can Marketers and Developers Start Using ChatGPT Today?

Connor boiled it down to something simple: pay the $20, and play.

That’s it. Start experimenting with tasks like:

  • Cleaning messy Excel or CSV data.

  • Generating charts formatted with your brand colors.

  • Debugging old code that no one left comments for.

  • Drafting project briefs based on client transcripts or meeting notes.

Every time you hit a wall, instead of Googling “how to fix a VLOOKUP” or waiting on a developer, toss it into ChatGPT with a clear request. The more you do this, the more natural it becomes to integrate AI into your workflow.

Should You Worry About Security?

Yes and no. The reality is simple: anything you put into ChatGPT could, in theory, live in its training data. That doesn’t mean your customer list gets emailed to a stranger, but it does mean you should avoid sensitive or regulated data like credit cards or medical information.

If your company requires strict compliance, you’ll want to look at secure, walled-off AI tools (like HubSpot’s ongoing ChatSpot project) where your data doesn’t leave the ecosystem.

The One Big Takeaway

Here it is: don’t just read about ChatGPT as a coding assistant—go play with it.

Upload a file. Ask it to do something you normally dread. Watch how fast it works. Feel your shoulders drop as hours of work melt into minutes.

Because this isn’t about robots replacing us. It’s about humans who know how to use AI flourishing in ways that others won’t. And when it comes to custom coding in HubSpot, the ones who learn how to collaborate with ChatGPT are going to be the ones who lead the charge.

So, what’s your move? Will you test, experiment, and explore? Or will you wait until the folks who did are already miles ahead?
