this app is phenomenal, and it will make it way more efficient if the developers add the feature of reading both words and paragraphs in both languages (the original and the translated) especially with natural voices available lately. personally i find the feature of translating paragraph by paragraph helpful, and it will be a nice addition to the app if you provide the ability to translate whole books and documents (along with keeping the paragraph translation feature) keep up the great work👏

Thank you so much for the kind words and detailed feedback! I'm really glad you enjoy the app and find the paragraph translation useful. Your ideas about bilingual reading, natural voices, and full-book translation are excellent and already on my radar for future updates. Thanks again for the support! 🙌

you can only translate one paragraph at a time. kinda lame. I'd like to be able to translate a whole book so I don't have to go paragraph for paragraph.

Thanks for the feedback! We totally get your point — translating paragraph by paragraph can feel limiting.
Full-book translation is already in our plans, and we’re working on making it smooth and usable.
Stay tuned 🙂
