Idea type: Swamp

The market has seen several mediocre solutions that nobody loves. Unless you can offer something fundamentally different, you’ll likely struggle to stand out or make money.

Should You Build It?

Don't build it.

Your are here

Your idea to translate selected words in a PDF reader app falls into a crowded space. We found 11 similar products, placing your idea in the 'Swamp' category, which indicates a lot of existing solutions that haven't really taken off. The average engagement for similar products is low, with an average of only 1 comment per product, suggesting limited user enthusiasm. Since we have a high confidence based on the number of similar products, we can expect competition. While there isn't any explicit negative feedback (net use and net buy signals are neutral), the lack of positive signals highlights the challenge in getting users excited about yet another translation tool. It will be difficult to differentiate and capture a significant user base.

Recommendations

  1. First, thoroughly research existing PDF translation solutions, focusing on user reviews and identifying pain points. Understand why they haven't achieved widespread adoption and pinpoint areas where they fall short. This groundwork is crucial to avoid replicating existing failures.
  2. If you proceed, focus on a very specific underserved user group. DocuTranslate received positive feedback on its intuitive interface, speed, and accuracy, but some users mentioned specific language needs (e.g., African languages, Arabic). Could you hyper-specialize in a niche language pair or industry-specific terminology to start?
  3. Consider creating tools that integrate with existing PDF readers or translation services rather than building a standalone application. Look into developing a plugin or API that enhances the functionality of established platforms, addressing specific needs that aren't currently met.
  4. Explore adjacent problems related to language accessibility, such as real-time audio translation or automated content summarization. These areas might present more promising opportunities with less direct competition and greater potential for innovation.
  5. Before committing significant time and resources, consider conducting thorough user research to validate your assumptions and gather feedback on your proposed solution. Create a landing page with a demo, or launch a kickstarter to test initial demand. If people aren't excited about your landing page, save your energy for a different idea.
  6. Instead of trying to build another generic PDF translator, how about creating an AI tool that auto-summarizes and highlights the key concepts of scientific papers or legal documents in PDFs in the user's native language? This would be much more valuable than just a simple translation tool.

Questions

  1. Given the existing solutions, what unique value proposition will your translation tool offer that genuinely solves a user problem and justifies its existence? Are you sure you are not building a solution in search of a problem?
  2. Considering the low engagement with similar products, what specific strategies will you implement to attract and retain users for your translation app, and how will you measure their satisfaction and engagement?
  3. How will you address the potential challenges of ensuring translation accuracy across various languages and contexts, and what mechanisms will you put in place to gather user feedback and continuously improve the quality of your translations?

This chart summarizes all the similar products we found for your idea in a single plot.

The x-axis represents the overall feedback each product received. This is calculated from the net use and buy signals that were expressed in the comments. The maximum is +1, which means all comments (across all similar products) were positive, expressed a willingness to use & buy said product. The minimum is -1 and it means the exact opposite.

The y-axis captures the strength of the signal, i.e. how many people commented and how does this rank against other products in this category. The maximum is +1, which means these products were the most liked, upvoted and talked about launches recently. The minimum is 0, meaning zero engagement or feedback was received.

The sizes of the product dots are determined by the relevance to your idea, where 10 is the maximum.

Your idea is the big blueish dot, which should lie somewhere in the polygon defined by these products. It can be off-center because we use custom weighting to summarize these metrics.

I made an app to read bilingually but different from others

18 Sep 2024 Languages

I recently built an app to read PDF books in any language. I found reading books in German or English challenging because there were many rare words that didn’t seem worth learning. Translating each word was tedious, so I created this app to make it easier. Simply select a word, and its translation will appear at the top.If you’ve faced the same issue, I’d love for you to try it out and share your feedback with me!

I made a tool to save time translating while reading

24 Oct 2024 Languages Productivity

As someone who loves reading to learn new languages, I recently decided to start reading books in Dutch to improve my skills. However, as a beginner, I quickly ran into a frustrating problem: I was constantly stopping to look up translations of words I didn’t understand.It felt like I was spending more time on my phone searching than actually reading the book! After a while, it really started to take the joy out of the experience.That’s when I started thinking – what if there was a tool that could help me translate words as I read, without having to manually search for them? So, I decided to build something myself that would allow me to read more fluidly without these constant interruptions.For anyone who's faced similar frustrations while reading in a foreign language, I’ve built a solution that help me a lot. If you're curious, feel free to check it out. I’m very open and eager for feedback, so if you have any suggestions or thoughts, I’d love to hear them.Thanks for reading!

Lexic – GPT-powered eBook reader for language learners

07 Dec 2023 Artificial Intelligence Languages

Hi guys, I created a simple ebook reader on top of Readium and the GPT API. The idea was to automate creating flashcards for any new words I encounter while reading foreign language literature. Before my process was the following 1. Highlight the word/phrase 2. Go back to all highlighted words when on my laptop 3. Check them in Google Translate 4. Get some context and examples from ChatGPT 5. Create a flashcard in AnkiThe app does all that automatically and I use it daily, so if anyone finds that useful, here is a URL for the TestFlight beta - https://testflight.apple.com/join/9pJ8x81Y .

GPT-4 eBook Translator – Read in Any Language

04 Dec 2023 Artificial Intelligence Books

Hey Hacker News community,I'm excited to share a project that's close to my heart and, I believe, a game-changer for book lovers around the globe. It's a GPT-4 powered tool that translates eBooks from any language into your native tongue, recompiling them into a perfectly formatted EPUB file.My Journey: For years, I've been an avid reader, primarily consuming books in English. Despite English being my second language, it became my go-to for literature due to the sheer volume and variety available. However, I noticed something: when I read in my mother tongue, my reading pace accelerated, and the words resonated more deeply. I didn't just read; I connected with the stories on a personal level. No more dozing off mid-page!One day, experimenting with GPT-4-Vision, I attempted translating a book. The outcome was astonishing. Not only was the translation fluid and natural, but it also retained the essence and style of the original work. This experience sparked an idea - why not make this accessible to everyone?The Project: I've developed a script that harnesses the advanced capabilities of GPT-4 LLM, specifically the gpt-4-1106-preview (GPT-4 Turbo) model, to translate eBooks. It meticulously preserves every element - chapters, footnotes, you name it - in the translated version. The best part? It's open source, and you can tailor it to your needs.I invite you all to try it, contribute, and join me in this mission to democratize literature. Let's make every book in the world accessible to everyone, in the language they think and dream in.Check out the project here: https://github.com/jb41/translate-bookLooking forward to your thoughts, feedback, and stories of how it might change your reading experience!Happy reading and translating
