Hey there!

Most people use ChatGPT for casual help, but what if you could make it behave like an absolute expert in exactly what you need?

No Custom GPTs. No jailbreaks. No hidden hacks. Just better language and smarter prompts.

This method is especially useful if you’re on the free version of ChatGPT where every prompt matters. In just three steps, you can unlock highly specialized conversations that save time, energy, and frustration.

LET’S. DIVE. IN. 🤿

Step 1: Identify and Describe Your Expert

Ask ChatGPT:

"Give me 20 words that describe a [specific expert]."

Example: "A lawyer who specializes in drafting legal documents."

ChatGPT will list words like Precise, Contract, Compliance, Binding, Legalese, and more. These words will form the "DNA" of your expert persona.

Step 2: Summon the Persona

Once you have the words, tell ChatGPT:

Using as many of these words as possible, write a 4-sentence prompt that would summon this specialist.

Make it sound like you’re calling a specific expert on the phone. The right tone pulls the model toward the kind of expert you need.

Step 3: Start Fresh

Open a new chat and paste the custom prompt you just created.

Important: Always start a new chat for a clean "mind." Otherwise, ChatGPT might get confused and compliment your great prompt instead of becoming the expert.


Real Examples You Can Use

  • College-level Python tutor:

"I'd like to speak with the Python tutor who teaches with clarity and patience…"

  • Tax preparer:

"I'd like to talk to the one who never misses a deduction…"

  • Lawyer for contracts:

"I'd like to speak with the attorney who drafts with precision and airtight compliance…"

  • Shakespeare expert:

"I'd like to speak with the scholar who knows Shakespeare as if he were an old friend…"

  • Vintage car mechanic:

"I'd like to talk to the gearhead who knows '67 Chevys better than most people know their own family…"

This trick turns ChatGPT into the ultimate on-demand specialist.
