Right before I was about to give up, reading with Moonlight helped me see the key points clearly and gave me confidence. I had to read 10 papers a week for seminar prep, but time was never enough. With Moonlight summarizing key points, I can now read 5 papers a day and presentation stress has decreased. AI papers were pouring in and it was overwhelming, but now I can quickly check the key points of the latest papers during lunch and have time to share ideas in meetings.
