How to Create Your First ChatGPT Plugin with ChatGPT (Step-by-Step Guide)

In this video I show you how to create your first ChatGPT Plugin with ChatGPT in a easy, step by step guide. I found this simple method of using ChatGPT to write the code and Replit to host it that is super beginner friendly, so this is a great way for you to learn how to build ChatGPT plugins without being too complicated!

More videos coming on creating more advanced plugins with much more powerful use cases so stay tuned!

First time viewer and I just got the magical email too. I'm a JS developer and also in the process of learning Python so I'm insanely pumped for this. Thanks for the video!

Can you set this up to run locally (localhost?).

I'm getting an error - Failed to fetch localhost manifest. Check to ensure your localhost is running and your localhost server has CORS enabled.

You are the holy grace of Ai education love your videos.

Thanks, Liam for explaining the process of building a plugin from idea generation to deployment with the help of ChatGPT. I learned a good set of tricks. Imagine if we had to do without using might be a weekend spent on documentation, experiments, and late nights.

Still waiting for a Plugin that can block out ChatGPT from generating cringy words
such as "with unwavering determination" "Facing the challenges that lay ahead." "With a renewed sense of determination"

[tspang]

Hi Liam, again, great video. I have a question. When we ask a question, how does ChatGPT know when to get the information from our plugin API and when to get the information from its own LLM? How can ChatGPT know which one to choose the information to response?

[danieldey]

Finally a tutorial that I was actually able to follow! Thank you.

[mamadoulamaranasow]

Hello Liam, thanks a lot for the Tutorial but I don't see the Develop your own plugin button in the Plugin store settings. Is it normal ? I live in France by the way if it might be a reason. Thanks in advance

[mamadoulamaranasow]

Bro I've just completed the waiting list on OpenAI to have the developper access. Do you know how long should I wait please ? Thanks in advance.

[jakobstyrupbrodersen]

Amazing tutorial! Thanks so much for demystifing coding a GPT plugin using GPT! 🙂

[DeepeshSachdev_Gaming]

Hi Liam! Can you also help me in Building AI Business? I am self-taught Developer with Good Coding Experience . I just want to create Business that will help in leaving my really bad 9-5 job and also help other

[runningninja]

Do you still need an ai-plugin.json file and /.well-known directory if you're making an API meant to be called as an action?

[cesarion]

I have no 'develop your plugin' button in chatGPT. Does anybody have this problem?

[ocbhu]

Hey Liam, I am totally new to using replit & while I did fork your code & update the secret access api key, it didn't show me the url, do I need to host it on replit & basically buy a plan there & then only will this work or am I missing something

To follow up with this tutorial to make plugin do we need ChatGPT plus subscription?
