Udemy Full Transcript Extractor for LLMs

I'm currently getting this message, "Failed to start recording: Error communicating with content script: Could not establish connection. Receiving end does not exist." I'd love to update my rating, can you please help?

I tested this extension on a full Udemy course with 9 sections and 42 lectures. While the tool does extract transcripts, there are serious limitations in its current form. What I experienced: The extraction stopped prematurely. Instead of all 42 lectures, only about 21 chapters were included in the final text file. (missing chapter 8, 10, 12, 16, 17, 19, 21, 23, 24, 28, 29, 31, 34–42) The output ended at lecture 33, even though the course continues to lecture 42. Several lectures that should contain transcripts were completely missing from the output file. Only the first lecture and the last one correctly displayed the “no transcript available” notice. The other missing lectures were marked as “no transcript available” – but they had available transcripts. Impact: This makes the tool unreliable for longer or more content-heavy courses, as it cannot be guaranteed that the entire transcript will be captured. It looks complete at first glance, but when compared against the real course structure, large parts of the transcript are missing. Positive aspects: The extension is easy to install and use. For shorter courses or single sections, it works partly and could completed manually. Conclusion: The concept is excellent, but the execution has a critical flaw: the extraction process does not capture full courses. Until this is fixed, the extension cannot be relied on for complete transcript exports.

While trying to run the extension on Udemy Business it failed saying "Failed to start recording: API request failed with status 403"
