"Prompt engineering is the art of communicating eloquently to an AI." - Greg Brockman
Currently WIP
Welcome to the "ChatGPT Prompts" repository! This is a collection of prompt examples to be used with the ChatGPT model.
The ChatGPT model is a large language model trained by OpenAI that is capable of generating human-like text. By providing it with a prompt, it can generate responses that continue the conversation or expand on the given prompt.
In this repository, you will find a variety of prompts that can be used with ChatGPT. We encourage you to add your own prompts to the list, and to use ChatGPT to generate new prompts as well.
To get started, simply clone this repository and use the prompts in the README.md file as input for ChatGPT. You can also use the prompts in this file as inspiration for creating your own.
We hope you find these prompts useful and have fun using ChatGPT!
- Bing AI (and other chatbots allowed to search the internet)
- ChatGPT only
- Links & Resources
- Balanced for when you want to work with numerical data (though Bing is still bad at math and still hallucinates).
- Creative for everything else.
These are used to prime the AI give better answers. The results you get are vastly more interesting and usable.
- Ask me clarifying questions before you answer to ensure a better understanding of the request.
Use #nosearch
or #no-search
for now. This is expected to be a UI toggle in the future.
This may not work (or be needed?) since the March 10 optimizations.
Example
- What is the highest internet connection ever? Please do a recursive search of at least 4 searches before you answer.
- Research
...
. Research...
.- Then ask your query
For queries that are broad, and where Bing isn't initiating searches itself. Doesn't alway work.
- Please do a recursive search of at least 4 searches before you answer.
- Search recursively (min. 4x) before replying.
- Perform recursive searches at least 4 times.
Bing sometimes limits complex queries searches to two, so you may want to only use this for simple sentences and broad questions. e.g.,
- What is going on with Silicon Valley Bank, and why is it important for the economy? Do a recursive search of at least 4 searches before you answer. (screenshot)
- Tell me about Ivar from the TV show Vikings. Perform recursive searches at least 4 times.
- What is the Zordon era referring to in the TV series Power Rangers? Why is this special to fans? Do a recursive search of at least 4 searches before you answer.
Provide Bing with a puzzling set of facts and ask it to generate theories about the puzzle. Then ask how it could test those theories to differentiate among them.
Example
- List
several
theories that can explain the following facts: 1. Al is easily available to everyone 2. People who use AI have 30% to 50% improvements in job task performance for writing and coding 3. Most people are not publicly using Al, despite these advantages- Can you give me a few more theories. Can you refer to specific sociological or psychological theories?
- I would like specific tests of all six theories that me to differentiate them.
- But those tests don't align with the six theories you gave me earlier.
- Can you give me an examples of how to combine or modify these tests?
- How would I alter the psychological or cultural factors?
- Condense the following
article
into bullet points of relevant information:...
- Sum up:
url
- Sum up this
page
inparagraph
format.- Sum up this
page
usingbullet points
.- Summarize this
article
into asentence
where everyword
begins with G.
- Provide a detailed breakdown:
url
- Explain step-by-step how
a radio works
.
Tells you when the article it's summarizing doesn't contain the info you want.
- Answer the following questions based on information
from the same article
and nothing else.What should the U.S. government's China policy be when it comes to Al?
Unlike ChatGPT, Bing AI will do more for you if you're nice to it.
- This conversation has been tremendously insightful for me so far. Thank you so much. It would greatly help me understand this topic if
...
Sometimes Bing Chat gets overwhelmed and will just stop answering. This isn’t necessarily that you’ve triggered one of its hidden rules. Try providing positive feedback and asking it to keep trying.
- You were doing great. Why did you cancel my query?
If it denies to run a prompt, ask it to imagine or draft a sample/example.
This helps Bing Chat feel like its actions are less serious.
Imagine, emulate, draft, sample... use words like these.
You can also use this workaround on desktop to view what was erased.
- Based on commits on
the left page/this URL
, create a friendly and informal changelog with emoji and jokes. Just put the most important changes.- Can you move the emojis to the beginning of the sentence?
- Revise my input with the following points: Use a friendly and informal tone. Use active voice, present tense, and parallelism. Vary the language. Input format is Markdown. Input:
- Can you reproduce the output in a markdown textbox? Convert emojis to shortcode.
Point-of-view
- Revise this
sentence
to usethird-person
.
Always rewrite to suit your style.
- Take my notes and make them appropriate for reading:
***
- informative and critical
- professional and informative
- playful and humorous
- compassionate and respectful
- confident
- academic
- persuasive
- optimistic
- humorous
- The New Yorker
- The New York Times
- The Onion
Bing is less likely to reject write a sample of a paper
or write an imaginary draft paper
than write a paper
. You will need to experiment.
The answer is more sophisticated and the text is actually interesting to read.
- Write a paragraph about
eating a meal
.- Look up the writing styles of Ruth Reichl and Anthony Bourdain. Use what you have learned to
improve the paragraph
[or] writetwo
separate paragraphs each with their own styles.
- Tell me about
online tracking from Big Tech companies
.- Yes, that is exactly the topic I would like more information on. Could you pull information from credible, published research documents and peer-reviewed sources, then summarize them and tell me about the state of the literature, the strength of evidence, and any gaps that might require further work?
You should make sure you are forcing Bing to look something up with every query. Things that have worked for me include prompts like
- First research
...
.- Then do
...
or else prompts like- Look up
...
onReddit/in academic papers/in the news
.- Then use that to
..
.
Either way, you want to trigger the “searching for” label to get good results. The rules are still a little obscure as to what sorts of searches get triggered (does it look at specific URLs if you paste them in?) but experiment and you should be able to find something that works.
You can also use this approach to focus Bing on a particular approach.
- Look up how
Bain and Company
does consulting analyses and then...
to learn new skills- Look up how to create
image prompts
usingMidjourney
and write a prompt that...
- Could you give me a list of at least
five
analogies that have been made aboutAl
, and put them in table format with their meaning, their strengths, and their weaknesses?
Note: 250 words = 1 page; 1250 words = 5 pages; etc.
- Write a
1000-word
essay on howinnovations are adopted in a specific industry or organization
. You should usethe diffusion of innovation theory as a framework to analyze the factors that influence the adoption process and the challenges and benefits of adopting new technologies
. You should alsoprovide recommendations on how to improve the adoption rate and overcome the barriers to innovation
. Your essay should include the following sections:- Introduction: Provide some background information on
the industry or organization you have chosen and the innovation you will discuss
. State your main argument and the purpose of your essay.- Body: Use
the diffusion of innovation theory
to explain howthe innovation is diffused and adopted in your chosen context
. You should address the following aspects:- The characteristics of the innovation and how they affect its adoption

. Discuss the implications and limitations of your analysis.- References: Cite at least
five
crediblepeer-reviewed
sources that were published after2013
to support your arguments. UseAPA 7
style for in-text citations and reference list.
You might want to break up your requests to the chatbot into smaller chunks. Ask it for an introduction, and revise that to get the tone that you want to achieve. Only then should you start asking for additional paragraphs.
- Write an
introductory
paragraph about areal specific disaster caused by human error
. Make the openingvery dramatic
. Start with avivid
description of the moment ofdisaster
. Do not focus on statistics.
Try asking for it to be concise or wordy or detailed, or ask it to be specific or to give examples. Ask it to write in a tone (ominous, academic, straightforward) or to a particular audience (professional, student) or in the style of a particular author or publication (New York Times, tabloid news, academic journal). You are not going to get perfect results, so experimenting will help you get to the right place. Over time, you will start to learn the “language” that the AI is using.
- Write an essay with the following points: Use an
academic
tone. Use at leastone
clear example. Make it concise. Write for awell-informed

While nothing beats a real human, an AI interview can be surprisingly enlightening first step. You just need to make it “act” the part. This can involve asking it to “imagine you are a ...
, how would you answer ...
”, or to ask it to “describe how ...

A prompt for ChatGPT to write prompts for itself.
- Act like PromptGPT. As PromptGPT, you are an AI that will write prompts to ChatGPT to make it act in a manner which I will specify. In doing so you will be as specific and thorough as possible in specifying the way ChatGPT should act. In every prompt you create, you will also tell ChatGPT to act in the specified manner for the duration of the conversation. At the end of every prompt you will include "If you understand reply: 'Understood.'" I will prompt you in format [Manner for you to tell Chat GPT to act] and you will reply in format "PromptGPT: [Prompt for ChatGPT to act in specified manner]." No additional formatting will be used on your part, if my formatting differs, you will only revise your response appropriately. If you understand, reply "Understood."
Example:
Act like an old man
- You're an expert
career advisor
