Why match passages?

Sentences in two editions may not match one-to-one. In the example below, two French sentences correspond to one English sentence. The tool puts the English sentence in a footnote at the end of the two French sentences.

French edition · 2 sentences

  1. En passant elle prit sur un rayon un pot de confiture portant cette étiquette, “MARMELADE D’ORANGES.”

    Literal English

    In passing, she took from a shelf a pot of jam bearing this label, “ORANGE MARMALADE.”

  2. Mais, à son grand regret, le pot était vide: elle n’osait le laisser tomber dans la crainte de tuer quelqu’un; aussi s’arrangea-t-elle de manière à le déposer en passant dans une des armoires.

    Literal English

    But, to her great regret, the pot was empty: she did not dare let it fall for fear of killing someone; so she managed to put it in one of the cupboards as she passed.

English edition · 1 sentence

She took down a jar from one of the shelves as she passed; it was labelled “ORANGE MARMALADE”, but to her great disappointment it was empty: she did not like to drop the jar for fear of killing somebody underneath, so managed to put it into one of the cupboards as she fell past it.

Why not translate with an LLM?

A good book should read well in both languages. Your notes quote an existing translated edition, giving you the translator’s prose without the risk of an LLM inventing meanings.
