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 for a book recommendation app based on reading history places you in a competitive space. We've seen 4 similar products, which means that while the idea isn't entirely novel, there is some validation that people are thinking about this problem. However, this also signifies that you will face competition. The lack of engagement (average of 0 comments) on these similar products suggests that current solutions haven't fully captured user interest or solved the problem effectively. Given the 'Swamp' category designation, it is likely that 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.

Recommendations

  1. Begin by thoroughly researching existing book recommendation apps and understand why they haven’t achieved widespread success. Analyze user reviews, identify pain points, and pinpoint gaps in their features or algorithms. A key starting point is to understand why people dislike Goodreads and Amazon as surfaced by similar products, and use this to formulate your value proposition and competitive edge.
  2. Instead of directly competing with established platforms, focus on serving a specific niche audience within the book-reading community. For example, target readers of a particular genre (e.g., science fiction, historical fiction), cater to a specific age group, or focus on readers with unique preferences (e.g., independent authors, audiobooks). This will give you a focused go-to-market strategy and a better chance of standing out.
  3. Consider creating tools or features that can be integrated into existing platforms rather than building a standalone app. This could involve developing a recommendation engine that independent bookstores can use to suggest books to their customers, or building a plugin that enhances the recommendation capabilities of platforms like Goodreads. Building an integration instead of a standalone app might also avoid the negative sentiment expressed by some users regarding 'manipulative algorithms.'
  4. Before investing heavily in this idea, explore adjacent problems in the book-reading space that might be more promising. For instance, you could develop a tool that helps readers organize their digital libraries, discover new authors, or connect with other readers who share their interests. These adjacent areas might present less competition and a greater opportunity for innovation.
  5. Before building anything, validate your assumptions by gathering feedback from potential users. Create a survey or conduct interviews to understand their needs, preferences, and pain points regarding book recommendations. Use this feedback to refine your product vision and ensure that you are addressing a real market need. Given the low engagement of similar products, getting user feedback early and often is crucial for success.
  6. Explore the possibility of integrating your recommendation engine with independent bookstores and libraries. By partnering with these organizations, you can tap into a loyal customer base and offer a more personalized and community-driven book discovery experience. The similar products' discussions highlight a preference for independent bookstores, making this a promising direction.

Questions

  1. Given the negative sentiment towards Goodreads and Amazon's algorithms, how can you ensure that your app's recommendations are perceived as genuine and aligned with user preferences, rather than manipulative or driven by commercial interests?
  2. How will you differentiate your recommendation engine from existing solutions, particularly in terms of data sources, algorithm design, and personalization capabilities, to provide genuinely novel and insightful recommendations?
  3. What specific metrics will you use to measure the success of your app in terms of user engagement, satisfaction, and book discovery, and how will you iterate on your product based on these metrics?

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.

Decide your next read from any booklist basis your Goodreads history

Hello all! I am a fintech product manager inspired by this community to build things.The motivation to build this came while going through NYT's List 100 Best Books of the 21st Century. I wanted to see which one I could pick as my next read. I realised that I couldn't get through the descriptions of the 100 books, then go through the process of searching Goodreads ratings for each, read people's comments, evaluate and so on. Could there be something faster which would give me an idea of which books I would like?So I built a MVP personalized book recommender which takes all your Goodreads reading history (thanks to Goodreads export option), creates a model (neural network) and then gives predicted ratings for any new book i.e. a prediction of how much would you rate it from 1 to 5 stars on Goodreads. This is especially useful if you are trying to decide which books to read from a long list of books. The model will give predicted ratings against each book and you can then choose if you would like to read something which has a high predicted rating or push yourselves towards trying something new.Since this builds a neural network-based predictive model right on the fly, it takes time to build if your reading history is long. I am trying to see how I can improve on that.I have just added 2 list of books against which you can get predicted scores - Obama's recommendations and Pulitzer list of books. Would love to hear from you if you want me to add another set of books. A feature in the works is extracting all books from a webpage against which you can get predicted book ratings. For ex: On book discussion pages on Hackernews, there are many books mentioned by community members. This model can help you decide which one to read next in a few moments!How it works? I am fetching book descriptions basis the title and author of book from Google Books API and then embedding the same using GPT-4. Then building a neural network with embeddings of each books descriptions and the ratings I have given in my reading history. I have used Pytorch to build the same.Would love to hear suggestions, comments, ideas, critiques!You can choose to reach out to me at: shubham13596@gmail.com or https://www.linkedin.com/in/shubham-gupta-50267a90/Thanks!
