I was skeptical at first, but the AI Summary Extension has really impressed me. The summaries are super concise and accurate, and the customization options are great to play around with. Of course you need an OpenAI key from OpenAI website and top up the credit. Had to find that out first but then it worked like charm. My only gripe is that the extension can be a bit slow to generate the summary (about 10 seconds), but it makes sense (and still is 1000x faster than I would take to summarise) and is worth the wait. I've been using it to summarize news articles and it's been a huge time-saver. Definitely worth checking out! Might even get an e-reader now - I didn't know you could send articles to e-readers - always only had books in mind.
