Genre-based book recommendations are broken. Someone who loves "The Great Gatsby" and "Norwegian Wood" doesn't want "literary fiction" — they want books that feel a certain way.
I built BookMoodMatch to solve this.
Why Mood > Genre
Think about the last book you loved. You probably wouldn't describe it by genre first. You'd say it was "cozy" or "mind-bending" or "made me ugly-cry on the train."
That emotional dimension is what BookMoodMatch uses. Instead of asking "what genre?" it asks "what mood are you in?"
How It Works
The matching algorithm considers:
- Current mood — contemplative, adventurous, cozy, intense, light
- Reading context — commute, vacation, before bed, weekend binge
- Past favorites — not just titles, but what you loved about them
- Avoidance signals — topics or tones you want to skip right now
The Data Challenge
Building a mood taxonomy for books is harder than it sounds. A book can be simultaneously "dark" and "hopeful." The same book reads differently depending on where you are in life.
I ended up with a multi-dimensional mood space rather than simple labels. Each book gets scored across several emotional axes, and matching happens in that space.
Results
The most common feedback: "This is the first recommendation engine that actually gets me." Genre systems put you in a box. Mood systems meet you where you are.
