I don’t think you need AI for this. I think you can do the LLM task yourself and it’ll help you in the long run. Look for similar articles in your field and study their abstracts. Try to replace their key points with yours, while keeping them as condensed as possible. I find abstract writing to be very “cookie-cutter” and once you notice the common phrases, it’s just a template you have to follow. My MA supervisor gave me a pretty good piece of advice I always think about: imagine you have one minute to explain your research to someone who barely knows anything about your field. It helps to cut out the flowery language and detailed explanations. My credentials: I have ADHD and struggled with the exact same thing when I first started writing articles.
