BookTr is a tool for reading texts in foreign languages. Features:

• Uses LibreTranslate API, but other APIs can be added later
• Side-by-side translation, aligned paragraphs
• Can save translations in json format
• Select a word to see its translation, double click to translate every word in a sentence
• Fully Self-Hosted, can work offline

Reasons for creating BookTr

The best way to learn a foreign language for me is by reading books in it. I tried doing it with Google Translate and other similar online tools, it's been frustrating: the interface is not suitable for long texts.

So, I decided to create my own)).

I am open to suggestions about adding other translation APIs, the only limit is - no paid ones. Only free online or self-hosted.

Quick start (Docker)

First, run LibreTranslate container. It will take some time (~20 minutes) and resources (~1Gb memory, 10+Gb disk). When you see it's web interface at port 5000, move on to installing BookTr.

docker run --name ltr \
    -p 5000:5000 \
  libretranslate/libretranslate

BookTr:

docker run --name BookTr \
    -e "TZ=$YOURTIMEZONE" \                  # your TZ here
    -e "LTRPATH=http://$YOURADDRESS:5000" \  # LibreTranslate URL
    -v ~/.dockerdata/BookTr:/data/BookTr  \ 
    -p 8856:8856 \
  ghcr.io/aceberg/booktr # or aceberg/booktr

Or use docker-compose.yml
