Stay witha book.
Make a little time. Settle into a book.
The original, the translation, your thoughts.
Each has a place of its own.

“What is the use of a book,” thought Alice, “without pictures or conversations?”
“一本书如果没有图画，也没有对话，那有什么用呢？”爱丽丝想。
After reading,
keep a thought of your own.
Pause beside a sentence and put your understanding into words. Leave what you have not resolved as a question, ready for your next visit.
Compare a difficult sentence with the original, a literal translation or an interpretation. AI translations are marked as drafts; untranslated passages keep the original.

The default books come from Project Gutenberg and are public domain in the United States. Source and license details are retained; check the rules where you live.
One book.
A room of your own.
Bring your own PDF, EPUB, Markdown or text file. The original and translations are kept separately, with a place for your own notes.
Leafhour is open source under AGPL-3.0 and can run locally or be self-hosted.
A few things before you begin.
What files can I import?
PDF, EPUB, Markdown (.md) and plain text (.txt) are supported. Check extracted PDF text against the source; scanned pages are recognized automatically once you confirm. EPUB uses its embedded reading order; encrypted or DRM editions are not supported.
Can I take my books and records with me?
Library export and restore do not require a subscription. After signing in, open Library → Settings → Data and migration for a ZIP backup, restore, or selected record export. Original files are optional. Unsynced records and drafts remain in the original browser. See the privacy and data notice.
What are the limits of AI and reading together?
Reading public samples needs no model request. Translation and conversation need a configured model service; self-hosters bear provider charges. Gift letters can share selected reading material. Live reading together with online presence is a future idea.
