Boosting Work Efficiency with ChatGPT and Generative AI for Working Professionals

Hello, I'm Jong-beom Lee.

I opened my first course in October 2024, and it will soon be the 1st anniversary.

For all the students who have taken courses so far

And to keep pace with the rapidly updating AI market

I plan to renew all lectures by October.

Additionally, we plan to include missions to make the lectures fun and practically applicable through hands-on practice.

The existing lectures will be moved to the very last section called "[Previous Lectures] Collection of Lectures Before Update".

Additionally, YouTube live lectures will be held in August.

You can attend live, and for those who can't make it due to time constraints, it will also be uploaded and provided as an Inflearn course after the live session.

The course was updated in August 2025.

I have updated a total of 3 hours, 42 minutes, and 41 seconds of lecture content so far.

This brings the total lecture time to 22 hours and 18 minutes.

We are also organizing and updating learning materials in Notion.

You can easily copy and use links or prompts from the lecture by clicking or clicking a button.

If you look at "View Class Notes" on the lecture screen, it is written as above. If you click on the "Learning Materials" link here, the Notion page will open as shown below.

Currently, we have created study notes only for the lectures updated in December 2024, but we plan to update study notes for other lectures as well.

Hello, this is Jongbeom Lee.

Are you listening to the lecture well?

How can I make it the best lecture?

How can we make this a lecture where we can improve our skills together?

How can we make this a lecture worth the money?

I keep thinking about it and thinking about it again.

These days, with new AIs coming out every day, it seems like AI lectures need to be updated.

Conditions for updates that were limited to December 2025

I changed it to unlimited as much as I could.

Honestly, I can't say for a lifetime.

I don't have the confidence to do it forever, but I will try my best to continue updating until at least December 2025.

I thought about making another AI course, but

I'm going to end my AI lecture with this one lecture.

We plan to continue updating the existing content as an all-in-one.

I have a lot of plans, but I don't want to blow an empty promise.

I will show you through an actual lecture.

I will continue to increase the benefits so that I can provide unconditional help to all students who trust me and purchase my classes.

It is expected that 2025 will be the full-fledged era of AI.

I hope that everyone prepares well and becomes a leading office worker!
