Your library speaks more than one language. So does Plumerie.
Filter by language. Auto-detect from ISBN. Link editions across languages. Built for readers whose shelves hold books in more than one tongue.
No app does this well — until now
You read in Finnish and English. Or Spanish and French. Or three languages. Your bookshelf is a mix — translations, originals, bilingual editions. And no app handles that well.
Goodreads does not let you filter by language. StoryGraph collects language data but cannot act on it. You have wanted to see “show me all my unread French books” for years. Nobody builds for readers like you.
Plumerie was built in Finland, by a multilingual team, for multilingual readers. Language is not an afterthought. It is a first-class filter.
How Plumerie works for multilingual readers
Auto-language detection
Plumerie identifies the book's language from its ISBN prefix when you scan or add a book. 45 languages supported, including Finnish, Swedish, French, Spanish, Japanese, and regional languages.
Language filter
Filter your library by language. "Show me my Finnish books." "Show me my unread English books." Instant, with no setup required.
Language stats
See your collection broken down by language on your dashboard. Track how your reading balance shifts across languages over time.
Edition linking
Connect the same book in different languages as editions of one work. Own Murakami in Japanese and English? They are linked.
A day in the life
You decide you want to read something in French this month. You open Plumerie, filter by language → French, then filter by reading status → Unread. Seven books appear. You pick one. That is it. No digging through shelves, no trying to remember which books were in French, no second-guessing. Your library knows.
Filter in two taps. Read what you intended to read.
Common questions
How does Plumerie detect the language of a book?
Plumerie identifies the book language automatically from the ISBN prefix when you scan or search. You can also set the language manually for any book.
How many languages does Plumerie support?
Plumerie supports 45 languages, including minority and regional languages. You can filter your library by any supported language.
Can I link the same book in different languages?
Yes. You can link editions of the same work across languages. If you own a book in both Finnish and English, they appear as editions of one work rather than two separate entries.
