AI is rapidly changing marketing, but navigating the hype to find what genuinely works takes hands-on experimentation. While basic AI chats have gotten much better since their release, we’ve found the real value comes from building custom GPTs for specific needs.

Their response is only as good as the information you give it. Having to give directions again and again to a generic model to match tone, stay factual, and avoid robotic language quickly burns time. Custom GPTs remove that friction when you set them up with at least these three essentials:

• Specific Source material: share key documents, data, and examples.
• Desired outcome: spell out the task and preferred output format.
• Target reader: note who will use the result and why they care.

Cover those three items once, and you're already saving time prompting.  

Over the past year and a half, we've built and refined custom GPTs internally to directly tackle the challenges faced by lean marketing teams. These GPTs aren't about replacing the human touch; instead, they provide strategic starting points, transforming raw ideas and data into actionable, editable drafts. This saves time which is one of the most important resources for small teams. 

Here’s a look at five of the most effective custom GPTs we’ve developed for real-world marketing challenges, helping our clients (and ourselves) cut through complexity and drive results.

‍Custom Marketing GPTs for Internal Use

1. Reporting Specialist - Our Reporting Specialist GPT acts like an expert analyst, that will take in your data and documents to highlight important insights and potential oversights. It acts as a second pair of eyes, summarizing key points and drafting comprehensive reports that streamline our final edits and presentations to clients. This GPT alone saves us 1-2 hours per client per month filtering and deep diving into data which adds up fast. 

2. LLMS.TXT Builder - Rapidly gaining popularity, our LLMS.TXT Builder educates first-time users by seamlessly drafting LLMS.txt files tailored to their websites. It not only ensures proper formatting but proactively identifies gaps and integrates best practices, optimizing site clarity for AI crawlers. This tool significantly speeds up the process for both newcomers and repeat users.

3. LinkedIn Post Generator - Despite years of experience crafting social content, writing my own posts can be daunting and overly analytical. Our LinkedIn Post Generator resolves this issue by converting articles, brand guidelines, writing samples, and strategic goals into authentic social posts. Instead of staring at a blank screen, we can quickly receive a draft reflecting our voice, freeing up time to refine and publish efficiently. This GPT is for internal use only as it’s built around our tone and ICP. 

4. Blog Drafting Assistant - We're firmly against fully AI-generated blog posts, human editing is essential for originality and genuine value. That said, our Blog Assistant helps kickstart the writing process by brainstorming ideas, outlining structures, or generating initial drafts from your ideas. It's creates a unique human touch by conducting voice-to-text interviews, ensuring the output is rich with your personal insights. This is also built only for internal use, want one for yourself?

5. Custom GPT Builder - Yes, a custom GPT for building custom GPTs. As custom GPT creation became frequent and more complex, we developed a GPT specifically to streamline the creation and training of additional GPTs. It guides users, new or experienced, through critical considerations, concept development, and rapid deployment, effectively making the process of building GPTs efficient and intuitive.

Setting up and training the custom GPTs can take a bit of time to get them dialed in, but once they're in a good spot you can start to see the time impact immediately. We're excited to ride the wave of AI to find meaningful ways it can drive tangible results.
