24 alternatives to BookTranslator

Hi HN! I built *BookTranslator.app* (https://www.booktranslator.app/) initially to help myself read English books in my native language. Later on as I shared on twitter, more and more people were finding it useful. So I thought it might also be helpful to share it here. You can drag-and-drop an *EPUB or PDF (≤ 50 MB)*, pick one of *76 target languages*, and ~60 seconds later you get a layout-preserving translation plus a side-by-side bilingual reader. The whole pipeline runs on the gpt-4o API with a bit of prompt-engineering to keep chapter structure, images and footnotes…

    So far I've used it to reference ideas from books I've read before. I've also used it to explore books I have not read before by asking the bot questions. Some people have told me they use it like a reading companion. They pause while reading the book if they have a question, and use Konjer to answer it.

    Hey HN! I love finding new books to read on here. I wanted to gather the most mentioned books and recreate the serendipity of physical browsing. I scraped 20k comments from HN threads related to reading, extracted the references and opinions using GPT-4o mini, and visualised their embeddings as a map. - OpenAI's embeddings were processed using UMAP and HDBSCAN. A direct 2D projection from the text embeddings didn't yield visually interesting results. Instead, HDBSCAN is first applied on a high-dimensional projection. Those clusters tend to correspond to different genres. The genre…

    Recently I launched BookTranslate.ai but at launch there wasn't really anything to see on the site. I should have thought about creating public demos before I launched, but now I added a few, including this one. I ran a blind analysis on the translation with Gemini: https://aistudio.google.com/app/prompts/1ZqeijNulqinp7D7wK1J... This is huge, in my opinion. I don't mean it to brag or sell, I mean it as a matter of fact that no other software can produce this level of quality right now and people thought machine translation will never be capable of this. I'm…

    Hello ! David from Spain here :) I built TransLite because I was tired of breaking my flow every time I needed to translate something before sending it. The usual workflow was: copy → open a browser tab → paste → translate → copy again → paste back. I've created a small macOS menubar app that lets you translate the current clipboard instantly using a keyboard shortcut, in any app. It works locally and supports using your own OpenAI / Claude API key. It’s intentionally simple — no accounts, no tracking, no subscriptions. Happy to answer any questions. Best regards, David

    Hi HN!! I'm a Chinese Translator, also a developer and I made this to solve my own problems. I got tired of waiting for official translations, so I built a tool that lets you read the original text and get a clean, consistent translation on the fly. I am not a translator by trade and that's probably why I have a different opinion than most translators for using clankers to translate, I have always felt that we should not be limited by language when it comes to wanting to read, this tool is mostly for people who do not want to wait for official translations and have a copy/purchase of…

    Since I was young, I've loved anime, and over the years, manga has brought me joy, given me courage, and sparked excitement in my heart. However, as I read more, I realized that many of these manga weren't translated at all. I also came across some AI-based translation tools, but the results often fell short. So, I decided to create a tool that allows manga fans to read and enjoy their favorite manga, no matter the language or whether a translation team is available. This product has just been launched, and there are certainly areas that can be improved. However, with time, I'm confident it…
