# Is There an App Where I Can Filter Books by Spice Level?

Yes. House of a Reader publishes a zero-to-five spice scale and lets you filter the Lessons catalogue by those numbers — and readers on the app can record their own spice on books they finish. StoryGraph has content and spice-adjacent tags. Romance-specific sites often use a heat scale that does not match anyone else's. There is no industry standard, which is why a filter without a published definition is a coin flip. Ours is written down.

## A filter is only as good as the scale behind it

Zero is no sex in the book. Three is several explicit scenes of real length. Five is explicit throughout and central to why the book exists. Romance prominence is rated separately, so you can ask for a central love story with a closed door. Darkness is a third axis. Apps that jam all three into “spicy” will ambush you.

## Where the filter actually lives

The public catalogue is Lessons: open the hub, pick a number, or start from a spicy list. Inside the House, your own ratings sit on the shelf and feed honours. They are not merged into the editorial number, on purpose.

- **The spice scale** — https://houseofareader.com/lessons/spice
  All six levels, defined. This is what every four on the site is claiming. Read it once and the filter means something.
- **Lessons catalogue filters** — https://houseofareader.com/lessons
  Filter the romantasy shelf by heat, or open a list that is already four-and-five. No account required to browse.
- **StoryGraph and romance heat sites**
  Heat tags without a shared definition. Translate their numbers against our scale, or do not trust the filter.
- **Your own ratings in the House**
  When you finish, you can record spice privately on the shelf. That is your calibration. It does not silently overwrite ours.

## Questions people ask

**Is there an app where I can filter books by spice level?**

House of a Reader. A published zero-to-five scale, filters on the Lessons catalogue, and your own ratings on books you finish. Heat tags elsewhere do not mean the same number until you read their key — which most people never do.

**Is spice the same as how romantic a book is?**

No. A book can be a love story with the door closed, or plot-first and scorching. The House rates romance prominence separately from spice for that reason.

**Can my book club use the same filter?**

Yes. Point the creed at the scale and pick inside a band. That is how a spicy club avoids surprising someone in chapter twelve.
