About Bilingual Book Maker
Bilingual Book Maker is an open-source AI translation tool that turns epub, txt, md, srt and pdf files into bilingual or multi-language editions, keeping the original next to the translation. It plans what to translate in a book so verse, lists and tables are not missed. Besides API keys, it can run through the local Codex CLI and spend your ChatGPT/Codex plan instead.
