Question: I need a service that helps me get a fast overview of a topic without having to read or watch the entire thing.

Unsummary gives you quick access to digested information about a wide swath of content, including books, movies, TV shows, podcasts and text. It's good for researchers, students and anyone who wants to stay current without working too hard.

Another top contender is Summarize This, which can summarize text, PDFs, websites and YouTube videos into bite-sized chunks. It's available for iOS and Chrome, and you can even get system-wide summarization abilities with shortcuts and extensions, so it's a good option for anyone who wants to be able to extract information quickly.

Briefy is another option worth considering. It converts long documents into structured summaries in different formats, like mindmaps, tables and short paragraphs. It works on multiple platforms and offers different pricing tiers, so it could be good for personal or professional use.
