What if you could have an AI assistant tailored specifically to your needs? Imagine a version of ChatGPT that always remembers your specific preferences, knows everything about your favorite hobbies, or can adopt a unique personality for specific interactions? That’s exactly what custom GPTs allow you to do.

9Personalization

One of the most obvious benefits ofcreating your own custom GPTsis that it allows you to personalize ChatGPT however you want. You can use custom instructions to change how ChatGPT behaves as a whole, but you might want it to act in different ways for different tasks.

For example, having ChatGPT always talk like The Stranger fromThe Big Lebowskimight soon become pretty tedious. However, you might want to create a custom GPT that you use to talk through problems and ideas thatresponds in a specific way. A custom GPT can behave exactly as you want it to, without affecting the rest of ChatGPT’s responses.

You can also give a custom GPT information about your interests, your industry, your location, and more. That helps to make the responses more appropriate to you. You might not want this information to be used in your daily interactions, but by including it in a custom GPT, you can get much more personalized responses.

8Saving Time on Repetitive Tasks

If there are things that you find yourself doing using ChatGPT on a regular basis, then creating a custom GPT may save you a lot of time. you’re able to set up a custom GPT with very specific instructions, so that when you want to achieve a goal, you just need to open that GPT and start typing. There’s no need for you to have to keep entering the same prompt each time explaining to ChatGPT what you want it to do.

For example, Iuse ChatGPT to searchfor How-To Geek articles on specific subjects. The natural language processing helps to bring up results that are often missed when searching in other ways.

It quickly became tiresome having to explain that I wanted ChatGPT to search only How-To Geek for articles that matched a specific topic and to explain how I wanted the results formatted. Instead, I created a custom GPT with instructions to do exactly that. Now all I do is open the GPT, enter a topic, and the results come straight up.

7Individualized Learning

ChatGPT can be a versatile learning tool. Whether you want toimprove your language skills, learn to code from scratch, or learn about the capital cities of every country in the world, you may use ChatGPT to help.

The beauty of creating a custom GPT is that you’re able to use it to tailor what you learn to your skill level and current progress. If you ask ChatGPT to test you on world capitals, for example, it might ask you some easy questions that you already know the answers to.

A custom GPT lets you explain what you want to learn, where you’re starting from, and what areas are your strengths or weaknesses. By including this information, you don’t need to start from scratch each time you want to learn something new.

For example, you could create a custom GPT and give it a list of the world capitals you’re already confident in. you’re able to then ask it to test you on the ones that aren’t on that list, but to occasionally throw in one from the list to make sure that you don’t forget them. Your custom GPT will then help you to learn the capitals you don’t know while reinforcing those you do.

6Creative Writing

Generative AI can be very useful in helping with creative writing. That doesn’t just mean you’re able to use it to do your writing for you, although it is good atcoming up with its own stories and content. However, you can use it as a tool to improve your own creative writing, too.

For example, you may create a custom GPT to help you brainstorm ideas for your own writing, or to generate writing prompts to help you practice writing your own content. You can create a custom GPT designed to critique your creative writing, to give you useful suggestions on how to improve it, or just to check it for errors. You can even make a custom GPT to help you create and flesh out characters by building their backstory, or allowing you to ask the custom GPT how your character would react in a specific situation.

5Creating Your Own Role-Playing Game

This is a really fun way to make use of the power of generative AI. You canuse ChatGPT to be the dungeon masterin your own bespoke role-playing game (RPG) and it can do a pretty good job of it. It’s not perfect, but it’s good enough to get a lot of fun out of.

Using a custom GPT is a great way to do this. It means that you may set up the world, the rules, the format you want for ChatGPT’s responses, and more, which can end up being quite a complex prompt.

By creating a custom GPT, you don’t need to have to set this up each time you want to play. Whenever you want to start a new game, just open your custom GPT and you can dive right in, without having to set everything up again from scratch.

There is a significant issue with this method, however. Custom GPTs don’t save your conversation history, so you can’t stop in the middle of a game and pick up from where you left off. If you want to be able to do so, you might want tocreate a ChatGPT projectinstead, which lets you apply custom instructions to multiple chats. That way, you’ll be able to pick up your RPG again in a saved chat within that project.

4Health and Wellness

Custom GPTs can be useful for providing personalized health and wellness tips. You can find many people in Reddit forums who have used ChatGPT to help with calorie tracking or togenerate personalized workout routineswith impressive results.

The beauty of a custom GPT is that you can tailor it to your own needs. If you create a custom GPT to generate workout routines, for example, you can provide information on the equipment you own or have access to so that it doesn’t suggest exercises that you’re not able to do. You can also get it to adjust to your current strength or fitness levels.

It’s important to remember that AI chatbots can give incorrect information. It’s not a great idea to use ChatGPT for medical advice or any other information that could put your health at risk.

3A Private Sounding Board

For many people,AI chatbots such as ChatGPTare useful as a way of being able to talk through problems without being judged or feeling embarrassed. An AI chatbot can feel easier to talk to than a real person who has their own things to worry about.

Creating a custom GPT lets you decide exactly how you want ChatGPT to work as a sounding board. you may give it instructions to encourage you to stick to your goals, or to give you life coaching for a specific aspect of your life, or just to listen and be sympathetic. By creating a custom GPT, you can quickly access your sounding board without having to repeat your instructions every time.

One downside of creating custom GPTs is that you can’t useAdvanced Voicewithin your GPTs. You can use the standard voice mode, but it’s not as natural or as quick to respond as Advanced Voice.

2Getting Help With Your Hobbies

Everyone loves a good hobby. Whether you’re obsessed with trying to make the perfect cup of coffee or spending ridiculous amounts of time and money building a homelab that’s wildly over-provisioned for your needs, a custom GPT can help.

For example, you could create a custom GPT that gives you gardening advice specifically for the plants you have in your home. You canget recommendations for movies, shows, or musicthat match your personal taste. You could even start your own book club with an AI companion that you can discuss your latest reads with.

The limit is only your imagination. Even if you have a very niche hobby, such as collecting 1950s fountain pens, you should be able to create a useful custom GPT that makes use of information from forums or other useful resources.

1Accessing Specialized Knowledge

Being able to access this kind of specialized information is a very useful way to take advantage of custom GPTs. you’re able to upload files to a custom GPT to provide it with information that it may not otherwise have. You can also request that it uses web search on specific sites that have trustworthy information, such as official forums or subreddits.

For example, I have a Home Assistant Guide GPT that I use to find information when I’m having a problemwith Home Assistant. The GPT is set up to use web search on the official Home Assistant forums, the Home Assistant subreddit, and the official documentation. It is asked to find the most up-to-date information available, so that it doesn’t give solutions that are no longer valid.

When I need help, I open the custom GPT and explain what I need, and the GPT will search for and present the information I’m looking for. It’s usually much quicker than trying to search the documentation or forums myself, and I can ask it to generate step-by-step instructions describing how to achieve my goal. The responses also include source links, so I can dive into relevant pages if necessary.

One of the biggest problems with ChatGPT is that there is so much you can do with it, it’s often hard to know where to start. The same is true of custom GPTs; you can create GPTs to do almost anything, so coming up with the ideas for what custom GPTs to make is often harder than making them. Once you’ve made a few, however, and realized how useful they can be, you may soon find yourself using them for all manner of things.
