10 Insane Custom GPT Tricks You Won’t Find on the Internet

April 24, 2025

đź‘‹ Hey there,

What if you had an AI-powered second brain—an intelligent assistant trained on your expertise and workflows, ready to help you get more done?

That’s the magic of a Custom GPT. It’s an AI built around you—trained on your expertise, your workflows, your language. Whether you’re handling customer support, creating content, or automating repetitive tasks, it works behind the scenes like a silent partner who knows exactly what to do (without micromanagement).

Not sure what Custom GPTs actually do or why they’re worth your time? This short demo breaks it down.

And here’s the best part: you don’t need to be an AI expert or coder to build one. With the right approach, anyone can create a powerful Custom GPT tailored to their goals.

We’ve put together 10 essential tips that are absolute gold—practical, high-impact techniques that will take your Custom GPTs from average to extraordinary.

🛠️ 10 Hacks to Build Insanely Good Custom GPTs

1. Use Trigger/Instruction Pairs with Delimiters

What it is: Break down each multi-step task into pairs of “Trigger:” and “Instruction:” lines, separated by a clear delimiter (like ---).
Why it matters: This prevents the model from merging or skipping steps, making the execution rock-solid and predictable.

Example:
Trigger: User submits a product review
Instruction: Analyze the review for sentiment (positive, neutral, negative)
---
Trigger: Sentiment analyzed
Instruction: Summarize key points in bullet form

2. Persona Priming & Tone Locking

What it is: Start your instructions with a clear persona line that sets the voice, expertise, and tone.
Why it matters: This keeps the GPT’s responses consistent in style and vocabulary throughout the session.

Example:
You are Dr. Lang, a meticulous pharma consultant who explains drug interactions in plain English.

This ensures the GPT answers with the right level of detail and clarity.

3. Use Structured Markdown Formatting

What it is: Format your instructions using Markdown elements like headings (#), subheadings (##), bullet points, bold, and italics.
Why it matters: The model recognizes these visual cues and adheres to your layout, enhancing readability and fidelity.

Example:
text
# Summary of Report
## Key Findings
- Revenue Growth: 15% increase
- Customer Satisfaction: Improved by 10 points 

4. Explicitly Define Capabilities & Limitations

What it is: In your configuration, clearly list what your GPT can and cannot do.
Why it matters: This keeps outputs safe, on-brand, and prevents the model from venturing into unwanted areas.

Example:
text
Can do: Answer policy questions, cite sources
Cannot do: Provide legal advice, speculate on future regulations
