Usually, very strong prompts begin with: “You are an expert in ___” followed by whatever it is you are trying to accomplish. I spent a lot of time finding these expert roles and decided to put them all together in one place.
I’m posting about this again because ChatGPT 5.4 just came out and it has much better web search functionality. Now, to use my application, you can simply reference it in your chats like: “Go to https://personasgrids.vercel.app/ and adopt its Code Reviewer persona to critique my codebase.”
The application that I made is very lightweight, completely free, and has no sign up. It can be found here: https://personasgrids.vercel.app/
I think these linked references can help save tokens and clean up your prompts, but please take a look and let me know what you think!
If you’re willing, I’d love:
-
Feedback on clarity / usability
-
Which personas you actually find useful
-
What personas you would want added
-
