Converse

Converse is a reading companion that stores web articles, PDFs and YouTube videos in a library and gives you TLDRs, detailed summaries and key takeaways for each. You can also chat with any saved item and get answers that cite the source.

Saved items are kept permanently and can be sorted into collections. Summaries let you skim a piece first and then open specific sections in more depth, and the chat answers questions with references back to the document.

Items and your chats with them can be shared with friends, who can interact with the document too. The free plan allows a handful of summaries and chat messages per month, while Plus removes those limits and adds image generation.
