With the growing integration of Artificial Intelligence (AI) in various sectors, content creation has not been left behind. AI has found its way into numerous websites, online publications, and content generation platforms, including Blinkist.com, a popular book summary service.
Blinkist has openly stated that they “currently use and explore Generative AI for various purposes, ranging from content creation and production to improving content personalization” (source). With the advancements and ability of AI tools like ChatGPT to generate content and efficiently summarize information, this isn’t surprising. Many companies and online tools are making their processes more efficient using AI technologies.
However, we wanted to dig into this further to understand exactly how much AI is being used by Blinkist in their book summaries. This study aims to understand the prevalence of AI-generated content on Blinkist.com and its implications.
Quick Takeaways
- Approximately 48% of the analyzed book summaries on Blinkist.com were suspected to be AI-generated content.
- A significant portion (35.82%) of the book summaries had a high confidence score (90% or above) for being AI-generated.
- The categories with the highest average AI detected are Education, Economics, Politics, Marketing & Sales, and Management & Leadership.
- While the most popular categories like Psychology and History have moderate levels of AI detected, categories with fewer articles like Education and Economics exhibit exceptionally high AI detection.
Methodology and Dataset
The analysis uses 402 book summaries from Blinkist.com, spanning various topics and genres. We only evaluated “Recently Added” book summaries, because we wanted to focus on summaries added since GPTs became publicly available. Each one was evaluated using the Originality.ai AI detection tool to determine whether it was AI-generated (>50% confidence) or human-written (<49.9% confidence). The book summaries were then categorized based on their AI confidence scores, with a score above 50% indicating suspected AI-generated content.
