How do you install ChatGPT? Can it be used on a PC, iPhone, Android, or iPad?
ChatGPT is an AI chatbot that has become popular worldwide. It can improve productivity in the workplace, during studies, and in everyday life. This has made it interesting to many users.
This guide will show you how to install ChatGPT and which devices it is compatible with (PCs, smartphones, and tablets).
What is ChatGPT?
ChatGPT is an AI-powered chatbot developed by OpenAI.
While there are premium plans, the official website offers free access to all users.
By June 2023, ChatGPT had received about 1.8 billion visits per month, which is 90 times more than Netflix, LinkedIn, Yahoo!, and Bing combined. It is now one of the top 20 websites in the world, just behind TikTok, which has about 2.1 billion visits.
Note: Initially, ChatGPT required users to register with an email address or phone number, but now it allows account-free access.

ChatGPT is a web-based service, so you can log in and use it from any device with internet access.
It works seamlessly on any device, whether it’s a PC, a tablet (like an iPad), or a smartphone (like an iPhone or Android). If you don’t have a PC, don’t worry.
How to Use ChatGPT
Here’s a step-by-step guide to get started:
Note: As of April 1, 2024, ChatGPT no longer requires account registration for basic use.
1. Visit the ChatGPT official page.
2. Click “Try ChatGPT.”

Once you’re logged in, the chat interface will appear. Type your questions or requests there. It’s that easy!
My Experience Using ChatGPT
I tested ChatGPT with a challenging request:
“Please suggest several catchphrases for a media platform covering smartphones, PCs, gadgets, and networking.”
Even humans might struggle with this task, but ChatGPT generated 10 unique proposals in under 1 minute—all in flawless Japanese!
Note: The video is shortened to 13 seconds for upload, but the actual response time was about 1 minute (including brief lag). During busy times, there might be a slight delay. If you need faster performance, consider ChatGPT Plus, OpenAI’s subscription plan that costs $20 per month (about ¥3,200).
Why It Impressed Me.
● Variety: All 10 suggestions were unique, providing great inspiration for my media project (Minna no RakuRaku Magazine).
● Versatility: Beyond catchphrases, ChatGPT excels at research summaries, music composition, and text editing.
Try different things—you’ll be amazed at what it can do!
Important Note: The better the prompts, the more accurate ChatGPT will be!
As ChatGPT becomes more popular, it’s clear that the prompts (input commands) you use are key to getting better responses.
A prompt is the text you input to ChatGPT. The accuracy and usefulness of the answer depend on how you phrase the prompt.
Here are some tips to improve prompts and get better results:
● One effective technique is to assign a role to ChatGPT, such as “You are a psychologist,” to customize the responses.
● Specify quality: Add terms like “most important” or “best.”
● Set output rules: For example, you could say, “Keep it under 100 characters” or “Use bullet points.”
Here’s a helpful tip: There are tools that can help you find recommended prompts, which can be useful when ChatGPT’s first response isn’t enough.

ChatGPT: A Tool Transforming Global Norms!
‘
ChatGPT is a useful web service that doesn’t need to be downloaded or installed—just have internet access. You can use it from your PC, smartphone (iPhone or Android), or tablet (iPad).
Key Milestones in Japan:
● On July 27, 2023, Microsoft announced that it is expanding its AI data centers in Japan. It is the first to provide ChatGPT’s core technology to the Japanese government. This is a major step in Asia’s AI adoption.
● Japan has one of the highest adoption rates of ChatGPT globally.
Why try it?
● It’s free and easy to start, making it ideal for work, study, and daily tasks.
● It is also compatible with various platforms (web/mobile).
● Japan is building more AI infrastructure, which makes ChatGPT work better and be more accessible.
If you haven’t tried ChatGPT yet, now’s the perfect time!
Here are the latest updates (2025):
● GPT-4o model: It responds faster and supports multimodal input (text, voice, and image).
● Japan is growing its AI technology. It has over 20 million active users and government-backed initiatives for enterprise adoption.
● Concerns about sustainability: People are talking more and more about how much energy AI uses. For example, making one image uses about 2.9 liters of water for every 100 requests.
