Best tool to summarise economic papers?

For university readings where we’ve been given 50-60 page reading docs, mainly empirical studies and their findings.

Which tool is useful for summarising this down to a more digestible 5-6 pages maybe?

Main reason for this is there’s not enough time to do all the readings and the lecturer encouraged us to do it this way and use AI – he wants to us to know the big picture or the studies such as method/conclusion etc.

Would appreciate any thoughts thanks. Essentially looking for a tool that doesn’t skip out the bits worth knowing about.
