I tried using ChatGPT.
I tried using ChatGPT myself.
(Note: The video has been shortened for upload purposes.)
I input a challenging prompt: “Please suggest several catchy taglines for a media outlet that shares information about smartphones, PCs, gadgets, and networks.”
Despite the difficulty of the task, ChatGPT provided 10 suggestions in less than a minute!Its Japanese responses were smooth and natural.
(The video has been shortened to 13 seconds for upload, but the process actually took just under a minute due to occasional delays. Currently, high demand may cause slower performance. If you want faster responses, consider subscribing to the paid plan ‘ChatGPT Plus,’ available in the U.S. for $20 per month (approximately 3,200 yen).)
ChatGPT came up with 10 taglines for this media outlet, “Minna no Rakuraku Magazine.” Each one was different and gave us great ideas.
ChatGPT can do more than just come up with taglines. It can also help with things like searching for information, summarizing content, composing music, and proofreading texts. Try it out and see what it can do!

Here are some tips:Using prompts can make ChatGPT more accurate.
As more people start using ChatGPT, it’s becoming clear that using specific instructions can make the answers more accurate.
A prompt is the text you type into ChatGPT. The way you write it can have a big effect on the quality of the answers you get.
Here are some examples of effective prompts:
-Set a specific role: “You are a psychological counselor.”
-Add quality indicators: “Give the best and most important points.”
-Specify the output format: “Write in bullet points” or “Keep it within 100 words.”
and more
Recently, tools have emerged to help find recommended prompts. If you’re not getting the desired answers from ChatGPT, these tools can be helpful to refine your input and achieve better results.
