Findsight

Findsight lets you search and compare the core claims from thousands of non-fiction books and articles instead of full text. It is built for readers and researchers who want to see how different authors handle the same question.

Results are individual claims, the main points a source makes, with links back to the original book or article. Clicking a title shows the context around a highlighted claim, and an arrow jumps to related claims from other sources, an approach the site calls syntopical reading.

Basic filters match literal text, while AI-powered filters let you pick named entities such as skills or Wikipedia-linked concepts and tagged topics, so a search for running can be narrowed to the sport. A random button drops you into a claim if you just want to browse.
