About Hikara
Hikara is a reading tracker that shows how your books connect. Every book you read becomes part of a larger story, and Hikara helps you see it.
Why we built Hikara
Have you ever finished a book and realised it changed how you understood another one you'd read years ago? That moment, when two seemingly unrelated ideas click together, is one of the most rewarding things about reading.
But memory is imperfect. Ideas fade, connections get lost, and the passage that changed your thinking is somewhere on your shelf, in a book you can't quite name.
Most book-tracking apps treat books as items on a checklist: read it, rate it, move on. That isn't how knowledge works. Ideas build on each other, argue with each other, and cross from one field into another.
Hikara treats your library as a network of connected ideas. Its AI looks at what your books are about, along with your own ratings and notes, and points out the echoes, challenges and bridges between them.
What we believe
Connections over collections
The best moments in reading happen when ideas from different books start talking to each other. A list records what you read; Hikara shows how it fits together.
Personal and private
Your notes, ratings and highlights belong to you. Your library is private by default, we never sell your data, and you can export it or delete your account at any time.
AI that explains itself
Every connection comes with the reason behind it, and the AI is instructed to be honest about how strong a link is rather than flattering your shelf.
Built for curious readers
For people who read across subjects, follow ideas wherever they lead, and want to see the bigger picture of what they've read.
What makes it different
Connections, not just a list
Each book's page shows the books it connects to and why, and the library visualizations show the overall shape of your reading.
AI that weighs your own notes
Connections aren't only matched on book descriptions: your ratings and notes go into the analysis, so what you found important shapes what Hikara finds.
Built for the habit, too
Reading sessions, streaks with automatic freeze credits, goals and a daily connection card help you keep reading, not just keep records.
What it doesn't do yet: there's no native phone app (Hikara installs from the browser), and imports read Goodreads' export format only. Our comparisons with other apps say where they're the better choice.
Who makes Hikara
Hikara is built by the Hikara Team. Our guides, comparisons and blog posts follow our editorial policy: claims about Hikara are checked against the product, claims about other apps against their own websites, and pages say when they were last updated.
