See how your
books connect
Hikara is a reading tracker that shows how your books connect. Import your Goodreads library or add books as you read, and watch ECHOES, CHALLENGES and BRIDGES appear between them, each scored 0–100 and explained.
Talk to your books.
They've been waiting.
Pick 1–5 books from your library and start a conversation. Each book speaks in its own voice — drawing on your notes, highlights, and the ideas inside it. In multi-book mode, the most relevant book answers each turn.
- Book voice rendered in serif type — feels like reading, not chatting.
- Grounded in your highlights, ratings, and personal notes.
- Multi-book panels — convene up to 5 books at once.
Atomic Habits
You've been asking about discipline. The truth is, you don't rise to your goals — you fall to your systems.
So how do I build the system?
Three relations. One graph.
Each connection Hikara finds between two of your books is one of three types, with a strength from 0 to 100 and a plain-English explanation.
Books that harmonize
Same domain, complementary ideas. ECHOES compound a theme — reading both books reinforces the pattern from different angles.
Books that disagree
Opposing viewpoints, productive tension. CHALLENGES sharpen your thinking — you only know what you believe by knowing what argues against it.
Cross-domain transfer
Distant fields, unexpected applications. BRIDGES are where reading earns its keep — when biology illuminates strategy, or art illuminates engineering.
