How to Build a Copywriting Bot for eCommerce Brands

Build a copywriting bot that captures your tone and speeds up content creation.

A copywriting bot can transform how your eCommerce brand produces content. Instead of rewriting drafts or struggling to brief freelancers, you can generate high-quality, on-brand copy in minutes. It’s a tool that helps you scale without losing consistency or voice – giving you more time to focus on growth.

The Foundation: Know Your Brand Better Than Anyone Else

Before building a bot, gather detailed information about your brand. At Shawfire Media, we give clients a brand questionnaire that covers customer avatars, top-selling products, problems your customers face, tone of voice, competitors, and even small details like a character or film your audience might resonate with. The answers help us map how the brand speaks and sells.

We often hear from founders that the process clarifies their own thinking. That’s how you know it’s working.

Build Your GPT Brief Using ChatGPT’s Custom Bot Feature

Once you’ve collected your brand’s DNA, follow these steps:

Go to chatgpt.com/gpts
Click Create in the top-right corner
Name your GPT (e.g., Shawfire-GPT)
Write a short description of what the bot does (e.g., “Writes copy for our minimalist supplement brand targeting high-performing men aged 25–40”)
In the configuration box, add:
- Key products and value props
- Brand tone and writing style
- Customer avatar details
- Unique selling points
- Words, phrases, or angles to avoid

Keep it short and clear. Avoid long paragraphs or irrelevant details. Clarity is what makes the bot work.

Set Preloaded Prompts to Speed Up Workflow

Add conversation starters so you or your team can move faster.
Example prompts:

“Write a plain-text email promoting our sleep product.”
“Summarize 3 objections and how we address them.”
“Draft a headline for our landing page targeting busy professionals.”

With these saved inside the GPT, you can generate drafts in seconds and spend more time refining instead of briefing.

Real Example: Content Scaling With a Copywriting Bot

One of our clients runs a men’s grooming brand with a bold, specific tone. They needed to scale content without losing voice consistency. We helped them build a GPT bot trained on their best-performing emails and tone rules. The result was a 4x increase in content output, a noticeable boost in engagement, and reduced reliance on external copywriters.

It became part of their marketing workflow, used daily by the team for product drops, campaigns, and upsells.

Common Mistakes When Building a Copywriting Bot

Cramming too much into the configuration box
Skipping tone details that define your brand
Using vague prompts like “write a product description”
Ignoring the testing phase – every good bot needs refining

Think of your bot like a new hire. Give it good onboarding. Review its first few outputs. Then it gets sharper over time.
