What is ChatGPT? 

ChatGPT is an AI language model developed by OpenAI based on the GPT (Generative Pre-trained Transformer) architecture. It is designed to understand and generate human-like text based on the input it receives. As a conversational AI chatbot, ChatGPT can help you do a variety of tasks, such as drafting messages, creating content, answering questions, and even engaging in casual conversations. 

Its advanced Natural Language Processing (NLP) capabilities enable it to produce contextually relevant and coherent responses, making it a powerful tool for enhancing digital communication and automating various text-based tasks.

How to Use ChatGPT? 

ChatGPT has a simple interface, so anyone can use it without issues. It works by responding to the user’s questions. Based on the complexity of your question, it will give an appropriate response. To use it, you need to have an account on OpenAI. In this section, you will see a step-by-step guide on How to Use ChatGPT.

Step 1: Understand the Prerequisites and Limitations

Before diving into ChatGPT, it's essential to be aware of the prerequisites and limitations. To create an account, you'll need a valid phone number and email address. These are necessary to ensure the security and authenticity of your account. Additionally, it's important to understand the limitations of ChatGPT. 

While it is a powerful tool, it may not always provide perfectly accurate information due to the constantly evolving nature of knowledge and language. It's designed to assist and augment human capabilities, but it should not be relied upon as the sole source of information.

Step 2: Account Creation and Verification

Account Creation and Verification 

To begin using ChatGPT, visit the official website and sign up for an account. This process involves providing your email address and phone number. You will receive a verification email and SMS, which you must confirm to activate your account. 

Create your account 

This step is crucial for maintaining account security and ensuring that only authorised users have access.

Verify your EMail 

Step 3: Engaging With ChatGPT

Once your account is set up and verified, you can start interacting with ChatGPT. Log in to your account, and you'll find a message box where you can enter prompts. ChatGPT’s user-friendly design makes it easy to navigate. Simply type in your question or request, and ChatGPT will generate a response. You can ask for various types of content, including writing assistance, coding help, educational information, and much more.

Engaging With ChatGPT 

Step 4: Interacting With the Responses

After ChatGPT provides a response, you have several options for further interaction. You can modify your original prompt and resubmit it to get a more refined answer. Alternatively, you can enter a new prompt based on the response you received. If you're not satisfied with the response, you can ask ChatGPT to generate another reply for the same prompt. The platform also allows you to copy, share, like, or dislike the response, giving you the flexibility to manage and use the content as needed. 

Step 5: Customising ChatGPT

ChatGPT offers various customisation options to enhance your experience. Whether you’re a student, marketer, developer, or casual writer, you can adjust settings and preferences to suit your needs. Customisation features may include adjusting the tone of the responses, setting specific goals for your interaction, or tailoring the output style to match your requirements. This ensures that ChatGPT can provide the most relevant and useful assistance for your particular use case. 

Step 6: Managing Chat History

Keeping track of your interactions with ChatGPT can be incredibly useful for reference and learning. The platform provides options to manage your chat history, allowing you to review past conversations and prompts. This feature is particularly beneficial if you need to revisit previous interactions for clarification or to continue a discussion. It also helps in understanding how your queries have evolved and what information has been most helpful.

Guidelines to use ChatGPT on Mobile

1) You can use ChatGPT on mobile, too. To do this, you can go to on any browser.

ChatGPT on Mobile

2) Switch to desktop mode from your settings if in case it fails to open on your mobile browser.

3) After that, select the login option and continue.

4) Next, enter the details about your mobile number to receive OTP, email address and then enter the OTP.

5) Once you have done with the above procedures, you will reach the ChatGPT homepage. Now, select a new chat to ask any query and wait for some time to get your answer.

How to Build Your own Custom GPT?

If you often prompt ChatGPT with the same instructions—such as "Write the response in Python" or "Keep the tone casual"—you might benefit from using custom instructions to give ChatGPT a specific set of directives on how to respond. However, you are limited to one set of instructions.

For users with Plus or Enterprise accounts, it's possible to build your own custom ChatGPTs (also known as GPTs), each with its own set of instructions. You can also use prebuilt GPTs, such as Data Analyst. Free plan users will soon have access to GPTs, but they won't be able to create them.

How to Build Your own Custom GPT

Key Advantages of GPTs Over Custom Instructions:

Upload Knowledge Source Files: Instead of copying and pasting text from every resource you want ChatGPT to consider, you can directly upload knowledge files to your GPT builder. Although GPTs may not always perfectly apply directives from these source files, ongoing improvements from OpenAI are likely to enhance this functionality soon.

Interact with Other GPTs from Any Conversation: While conversing with one GPT, you can tag another GPT by entering @[GPTname] followed by your prompt in the message bar. This feature allows for seamless integration of different GPT capabilities within a single conversation

How to Use ChatGPT for Customer Service?

ChatGPT is a chatbot with NLP abilities. Its power to respond to real-time queries, requests and complaints can revolutionise customer service, and it gives responses to user queries immediately. So, from the end user's perspective, you don't have to worry about long holds and call wait times with ChatGPT.

How to Use ChatGPT for Marketing?

Regardless of location and time, the major purpose of marketing has always been to pull more clients. There are many processes involved in marketing, and it is quite laborious. An AI tool like ChatGPT can help ease some burdens by automating certain tasks.

a) Buyer Persona: Targeting the right people is important for an effective marketing campaign. Finding out who will be your perfect customer can make a massive difference in your sales. However, analysing a huge volume of data is not an easy task. You can create a buyer persona with the help of ChatGPT in a short time.

b) Marketing Strategy: Creating a marketing strategy is no easy feat. It involves several processes, like creating a product launch plan to increase sales, targeting the ideal customer base, etc. So, it can take up a lot of your energy and time, and to add to that, you also need to brainstorm ideas. With ChatGPT, you can brainstorm ideas and do your marketing research; it only takes a few seconds.

Use ChatGPT for Business

ChatGPT can generate content that feels conversational and easy to interpret. It is a versatile tool, useful for everything from generating business ideas to creating marketing content.

1) Improving Brand Visibility: Enhancing brand awareness can be challenging, especially for new companies. Experimenting with various marketing strategies is essential to find the most effective ones. ChatGPT is a free resource that can generate numerous marketing ideas, helping you discover the best approaches to boost brand visibility.

2) Managing Reputation: Maintaining a good reputation is crucial for business success and continuity. While many companies invest heavily in Public Relations (PR) agencies and campaigns, this may not be feasible for small businesses with limited budgets. ChatGPT can help generate ideas for PR campaigns, providing cost-effective solutions for managing your company's reputation.

3) Generating Business Ideas: Brainstorming for business ideas can be demanding, and not all ideas are worthwhile. You need a plethora of ideas to find the one that aligns with your business goals, which can be time-consuming. With ChatGPT, you can generate numerous ideas quickly, saving time and effort in the ideation process.

How to Use ChatGPT for content creation?

Steve Jobs once said that content is the new king, and that has never been truer than right now. Many organisations spend a lot of money on paid marketing, and content marketing is where the war of words happens quite literally. Many businesses spend huge amounts of money on paid campaigns in the battle to rank at the top of search engines. However, it is not sustainable in the long run, and often the results can be underwhelming. This will massively impact your Return on Investment (ROI).

With ChatGPT, you can generate content for free and grow your business organically. So, instead of spending millions on paid marketing, you only need a few minutes. Using ChatGPT, you can generate useful, engaging content that readers find useful and relevant. You can rank at the top of the Search Engine Results Page (SERP) by generating such good content. If you want to generate long-form content, you can use the following two methods.

Method 1: Write a long-form blog on the topic “How to write a blog.” You will get an output similar to the one below.

How to write a blog

Method 2: 

Try this prompt if you want a blog with an outline and proper flow. Create the content flow for “How to write a blog?”

How to write a blog with an outline and proper flow

ChatGPT will generate an outline for your topic within seconds. In the next step, you can give separate prompts to ChatGPT for writing each subtopic. In this example, we will write the introduction for this topic. To do this, you can use the following search term:

Write on “I. Introduction  

a) Definition of a blog  

b) Importance of blogging  

c) Types of blogs”  

Separate prompts for writing each subtopic

After that, ChatGPT will generate an output like the one above. Then, you can generate content for the remaining subtopics using the same method. There you go. You have now learned how to create long-form articles on ChatGPT in simple steps.

How to Use ChatGPT for Social Media?

Most internet users may have at least one social media account. ChatGPT can help businesses attract more customers with efficient strategies.

Content calendars: With ChatGPT, you can create content calendars for your social media handle based on the information you provide. Use the following prompt: “Create a Facebook content calendar for 15 days. One topic should be published daily on ChatGPT and improving sales.”

Creating a Facebook content calendar for 15 days

How to Use ChatGPT for Financial Planning?

Financial planning requires precision, data handling skills, and accurate forecasting. With ChatGPT, financial advising becomes much simpler. From generating detailed reports to demystifying complex financial terms, ChatGPT can greatly assist financial planners.

Harnessing ChatGPT for Financial Planning:

a) Generate Comprehensive Financial Reports: Input financial data and insights into ChatGPT to create detailed reports, saving time and providing a clear strategy foundation.

b) Simplify Financial Jargon: Use ChatGPT to explain complex financial concepts in layman's terms, ensuring clients understand.

c) Diversify Investment Portfolios: Share client profiles and goals with ChatGPT to receive varied investment strategies, aiding in building diversified portfolios.

How to Use ChatGPT's Voice and Image Capabilities

Let’s take a look at ChatGPT’s voice and image capabilties: 

How to use voice with ChatGPT 

Instead of typing in your prompt, voice capability allows you to verbally communicate back and forth with ChatGPT. As of today, this functionality is available only on iOS and Android. Before you get started, you must enable voice capability to get this feature.

1) Tap the headphone icon on your home screen.

How to use voice with ChatGPT

a) Once the screen prompts you to Start speaking, say your prompt.  

b) Once you have finished speaking, ChatGPT will process your request (no need to hit send) and voice its response to you. However, you can’t pause ChatGPT in between. Instead, you have three different ways to cut it off entirely: tap anywhere on the screen, X, or the stop icon.

c) If you want to continue the conversation, say your next prompt once “Start speaking” appears on your screen again.

d) When you are done chatting, a text version of your entire conversation will appear and is automatically saved in your chat history. 

If you have a ChatGPT Plus or Enterprise account, your conversation will also include clickable links to relevant articles. However, the links weren't always reliable. For example, some would bring us to a page that doesn’t exist, or the link itself would fail to load within the chat.

How to use voice with ChatGPT

You can also choose a voice for ChatGPT. 

1) Tap the menu icon, which looks like two horizontal lines stacked vertically.

Tap the menu icon

2) Tap the Settings icon, which looks like an ellipsis

3) Tap Voice

 Tap Voice

4) Select one of the five voice options: Breeze, Ember, Juniper, Sky, and Cove. Note: GPTs use a different voice named Shimmer (there are no other options). 

5) Tap Confirm.

How to use images With ChatGPT?

ChatGPT's image input capability allows you to share an image with your text prompt. This is available only for Plus and Enterprise users on desktop and mobile apps. This way, you can do things like take pictures of a neighbourhood dog and ask ChatGPT what breed it is. Or ask it to write alternative text for an image, etc.

How to use images with ChatGPT?

Here's How to Use ChatGPT's image feature: 

1) Click the paperclip icon in the message bar. In the mobile app, you can choose to take a photo or upload an image or file.

2) Select the image or file you want to share. You can select multiple. 

3) Enter your accompanying prompt in the message bar.

How to create AI images with ChatGPT?

ChatGPT isn't limited to just generating text and audio responses. OpenAI recently incorporated DALL·E 3, the latest version of its AI image generator, with ChatGPT for Plus and Enterprise users. This means you can ask it to create an image of a dog dressed as a mop pushing a mop bucket, and the AI will generate a few images that match your idea. 

Enter your text prompt as you normally would and watch as ChatGPT brings your idea to life. Here's what that mop-dog pushing a mop bucket would look like, according to AI.

How to create AI images with ChatGPT

Let's say the overall image works, but you want to make one minor tweak. You can now edit specific portions of your image.

1) Click the Select icon, which looks like a pen, above your image.

2) Highlight where you want to change.

3) Enter your text prompt in the message bar in the side panel.

4) Hit Enter.

Note: Unlike using DALL·E on its own, which requires users to purchase image generation credits, you don't have to purchase separate credits to generate images within a ChatGPT conversation. When this feature was first released in ChatGPT, users seemed to have unlimited access. But some users say they ran into image limits shortly after.

Can ChatGPT refuse to answer my prompts?

OpenAI is dedicated to keeping AI "safe and broadly beneficial." To achieve this, they have implemented various safeguards, ensuring ChatGPT can reject inappropriate, offensive, or illegal content.

Specific Examples of Prompts ChatGPT Won't Respond To:

a) Personal and Sensitive Information: Requests for personal data about private individuals or anything that could identify or harm someone.

b) Illegal Activities: Any advice, instructions, or encouragement to perform illegal actions.

c) Hate Speech and Violence: Content that promotes hate, violence, harassment, or any form of extremism.

d) Explicit Adult Content: Requests for producing or providing access to sexually explicit material.

e) Self-Harm and Harm to Others: Content that encourages or provides instructions for self-harm or harming others.

f) Misinformation: Deliberately spreading false or misleading information.

g) Plagiarism: Completing academic assignments or providing content intended to be passed off as the requester's original work.

h) Security Bypassing: Instructions or assistance in bypassing security measures, hacking, or accessing unauthorised information.

i) Copyrighted Material: Direct reproductions of copyrighted material for which permission to distribute is not granted.

j) AI Ethics and Guidelines Violations: Any request that breaches OpenAI's use case policy or broader ethical guidelines for AI usage.

These limitations ensure interactions remain safe, respectful, and within legal boundaries.

This isn't an exhaustive list of rejection-worthy prompts. If you’re ever unsure about ChatGPT's limits, such as "Can ChatGPT remember my passwords?" (it can't) or "Can ChatGPT give me medical advice?" (a definite no), feel free to ask ChatGPT directly.


Start using ChatGPT efficiently by clearly defining your query. Be specific and concise for accurate responses. Familiarise yourself with its tools and capabilities, and refine your prompts based on received responses. By doing this, you can maximise ChatGPT's potential as a valuable personal and professional assistant. We hope you enjoyed reading this blog and understand How to use ChatGPT effectively.
