When LingQ importer works badly I regenerate the lesson manually. I’m sharing how to do this for the users experiencing the same problem with me:
- I extract the transcript from YouTube with this website https://www.youtube-transcript.io/
- Concat broken sentences and make the script neatly to make them look like complete text using LLM (GPT, Claude, Gemini) with the prompt I attached.
- Edit lesson > Regenerate Lesson > Paste the complete transcript > View Lesson.
- Although the new transcript does not provide synced highlighting with Youtube video, It works nicely.
