See how the books you read connect
Hikara's AI looks for connections between the books in your library and labels each one: an echo (two books reinforcing the same idea), a challenge (two books that disagree) or a bridge (books from different fields that share an idea). Every connection gets a strength from 0 to 100 and an explanation you can read.

How connections are found
When you add a book, Hikara compares it with the books already in your library. For each pair, the AI considers the titles, authors and subjects along with your own ratings and notes, then decides whether there's a real connection and what kind it is.
It's instructed to be honest about strength rather than generous, so a loose resemblance scores low instead of being dressed up as an insight. Each result is saved, so a connection between two books is only worked out once.
Where you see them
Connections show up wherever they're useful:
- On each book's page, with the books it connects to and why.
- As a daily connection card on the Reading tab.
- On the Insights page, grouped into clusters and as your strongest connections.
- As share cards you can post, and on public pages for well-known pairs.
You can push back
Connections are suggestions with reasons, not facts. You can agree or disagree with any connection, and your notes on a book feed into what the AI finds next time.

Questions
How many books do I need for connections?
Two. A connection is between a pair of books, so it can start working as soon as your second book is in. The more you add, the more there is to connect.
Does Hikara read the books themselves?
No. It works from each book's title, authors and subject categories, what its AI model already knows about well-known books, and your own ratings and notes.
What's the difference between an echo, a challenge and a bridge?
An echo is two books reinforcing the same idea; a challenge is two books that disagree or pull against each other; a bridge links books from different fields that share an idea.
