Suddenly my courses are vanished.

I created my Udemy account 3 months ago. I started to create the courses. I uploaded all my courses via the Bulk CSV format. Now I have 23 active courses, and all are vanished. When I open my account I get this message to all courses

23 courses in 3 months is pretty amazing. You probably need to contact Udemy support.

Hi @shah123, thank you for your post, and I’m sorry for any trouble caused.

As @RonErez said, the best course of action here is to contact our Instructor Support team so they can take a closer look at your account and see what’s going on with your courses. You can reach out to them by clicking the “Contact Us” option in this article.

Best regards,

@shah123 Can you explain how you can create 23 courses in that short a period of time? On the face of it, it is not credible and unless there is something I don't understand, it is easy to see why Udemy blocked them. It took me six months to develop my first course, and that was on a subject that I had taught live and written about at length. I don't get it.

I would typically agree with you on this, but since Udemy has begun allowing AI for course creation and voiceover, I can see it being very easy to churn out content like this, which is why I was against it.

I am not sure what is allowed in using AI and what isn't. Maybe we need better clarity.

AI can be a good tool to assist an instructor and save time in research. It should not become an alternative for Knowledge. On Udemy I can clearly see that AI is becoming an alternative for Knowledge and is being used as a course producing factory.

Hi Lawrence,

We do have several HC articles about the usage of AI. You can find more information below:

If you have any general questions, feel free to let me know. For more specific inquiries, it’s best to reach out directly to our Policy team at policy@udemy.com, as they’ll be able to provide expert guidance.

Fully agree. 23 courses in 3 months is 2 courses per week. Imho, that's pretty much impossible to do for a credible expert who applies deep knowledge and experience.

I disagree. It is quite possible to take a topic and do several short courses on that topic. First example: Dementia. From that one topic one could make:

Dementia - how to reduce your risks

Dementia - causes and risk reduction

Dementia and Alzheimer’s for the caregiver

Art therapy and dementia

Dementia: signs, symptoms, care and prevention

Advanced diploma in dementia care

Of course those could all be one course - but equally they could be standalone courses, each with Diplomas blah blah.

I made a course in Art Therapy. 102 hours long. Took ages.i stressed it didn’t make you an art therapist. Another Instructor made a one hour course and said it did make you an art therapist.

He sold more.

So, two courses a week? Pre-AI I would not be surprised if someone made 2-3 courses a day . And now…

Of course people argue about quality but there are plenty of really good short courses around. I’ve also seen courses that are just videos of someone teaching in a school. So he delivers the lesson, minimal editing, uploads ( mentions his book a few times) a

Dr. Kat

I respect your perspective, thanks for sharing, Chris!

there’s no problem with bulk uploading IF quality is maintained:

That seems fair enough

@shah123

He mentioned that he used the bulk CSV method to upload his courses, which makes it entirely feasible that he published multiple practice tests. Publishing 23 practice tests in three months is realistic and achievable.

Some instructors claim they took six months—or even a year—to create a single course, as if the time spent alone guarantees higher quality. But let’s be clear: taking longer doesn’t automatically mean the course is excellent or that students will love it.

In fact, if an instructor takes six months to build one course, it may suggest they are not using efficient tools, their editing process is slow, or they lack a capable team. On the other hand, completing a course in 10 days doesn’t mean the quality is poor—it may simply reflect good planning, better tools, and a streamlined workflow.

So instead of assuming that more time equals more quality, the focus should be on what is actually being taught, how effectively it's delivered, and what kind of outcomes students are experiencing.

Udemy should evaluate the quality of the content, not the number of courses published within a specific time frame. If a course lacks value or doesn’t meet platform standards, then it’s fair to ask the instructor to improve or remove it.

At the end of the day, this is a learning platform. Instructors should have the freedom to use any tools or methods—as long as the final result provides a high-quality learning experience. The real measure should be learner understanding, course engagement, and student reviews—not how long it took to produce the course.

@Avnish, I’m not making any such assumptions, I just said that I’m impressed with the output.

As a side note, have a look at my iOS course. You’ll see that it’s the greatest course in the history of humanity on iOS development. Note that the course is 90 hours long so it would be somewhat of a miracle if I could complete it in a week. Note that a major drawback of the course is that it is so long. Nevertheless it is still amazing.

I know some topics don’t need as much time. I suppose it depends on the topic and on the instructor’s approach.

Avnish

@RonErez I understand.
