How to find connections between the books you've read
To find connections between the books you've read on Hikara: import your library (Goodreads CSV or manual add), open your knowledge graph, then click any book node to see its ECHOES, CHALLENGES, and BRIDGES with the rest of your library. The AI scores each pair 0–100.
Most reading tools tell you what you've read. A reading knowledge graph tells you how those books talk to each other. Here's the four-step path to your first connection on Hikara.
Before you start
- A free Hikara account.
- At least 5–10 books in your library (more books = richer graph; under 5 books gives sparse results).
Steps
Step 1
Get books into Hikara
Either import via Goodreads CSV (see the Goodreads import how-to) or use the in-app book search to add books manually. The richer your library, the more connections Hikara can find. 20+ books is a comfortable threshold for the graph to feel useful.
Step 2
Open your graph
Click the "Graph" link in your dashboard. Hikara renders your library as a force-directed graph — books are nodes, connections are edges. Edges are colored by relation type: gold for ECHOES, violet for CHALLENGES, blue for BRIDGES.
Step 3
Click any book to see its connections
Click a book node. The detail panel shows every connection from that book, with the relation type, the strength score (0–100), and the AI's plain-English explanation of why those two books echo, challenge, or bridge each other.
Step 4
Use the gap finder to discover what's missing
From the graph, click any 2–5 books and choose "Find a bridge". Hikara's AI suggests one new book whose addition would connect the chosen books in a new way — useful when planning your next read or building a reading list around a theme.
Troubleshooting
The graph looks sparse.
Hikara generates connections in the background as you add books. If you just imported, give it a few minutes — connections fill in as the AI processes pairs.
I can't tell which connections matter.
Sort connections by strength (descending). Pairs scoring above 70 are usually meaningful; below 50 are weak signal. Strong CHALLENGES and BRIDGES tend to be the most surprising and most useful for thinking.
FAQ
What kinds of connections does Hikara find?
Three relation types: ECHOES (books that harmonize on a similar theme), CHALLENGES (books that oppose or sit in productive tension), BRIDGES (cross-domain connections — e.g., a biology book that maps onto a strategy book). Every pair is scored 0–100 on each.
How does Hikara generate the connections?
An LLM analyzes book metadata (title, author, description, categories) plus your personal notes and ratings, looking for non-obvious patterns across themes, structures, ideas, and emotional registers. Connections are cached after the first run, so subsequent loads are instant.
Are connections accurate?
Connections are suggestions, not statements of fact. They reflect the model's best read of the available metadata. Hikara scores conservatively (most pairs land 30–60), and surfaces the strongest non-obvious links rather than the most generic ones.
