Findsight AI
Findsight AI is a search engine for comparing core claims pulled from thousands of non-fiction books, articles, and papers. You filter by literal mentions, named entities, topics, stated claims, or natural-language questions, then follow related claims with the explore arrow to build a syntopical reading path. Each result links back to the original source so you can go deeper than the excerpt.
Google finds pages; Findsight indexes individual claims and shows how different authors answer the same question side by side. The state and answer filters use embeddings to match meaning, while mention and references filters handle keyword and entity precision that pure semantic search often misses.
Students, researchers, and curious readers use Findsight AI when they want to compare perspectives across sources without reading every book cover to cover. The site is free with no signup, and the state and answer filters allow 50 searches per day before you need to drop those filters to keep searching.

What is Findsight AI?
Findsight AI is a search engine that indexes claims, the key points from non-fiction books and articles, so you can compare how different authors address the same topic. Findsight AI combines keyword, entity, topic, and AI filters to explore related ideas.
Is Findsight AI free?
Yes. Findsight AI is free to use with no sign-up required. State and answer filters allow 50 searches per day; you can continue with basic mention, reference, and discuss filters after hitting that limit.
How do Findsight AI filters work?
Findsight AI offers mention for literal text, references for named entities, discuss for topic tags, state for finding related claims, and answer for question-based retrieval. The state and answer filters use AI embeddings while the others use traditional search.
What is syntopical reading on Findsight AI?
Syntopical reading on Findsight AI means comparing claims across multiple sources on the same subject. Findsight AI lets you jump from one claim to related claims with the explore arrow and build your own cross-author learning path.
Who built Findsight AI?
Findsight AI was created by Pierre at Summarity and launched in 2023. Summarity describes Findsight as a discovery tool for finding books and articles to read further, not a full-text consumption platform.
Does Findsight AI link to original sources?
Yes. Findsight AI results include links to the original books or articles behind each claim. Clicking a title expands surrounding claims for more context before you follow the explore arrow to related ideas.
