Some expressed concerns about the long-term viability of a subscription model for search, wondering if Kagi could maintain quality and compete with free, ad-supported giants. The integration with Kagi's existing search engine was generally seen as a positive, though some questioned its usefulness for simpler searches. A few commenters noted the potential for bias and the importance of transparency regarding the underlying model and training data. Others brought up the small company size and the challenge of scaling the service while maintaining performance and privacy. Overall, the sentiment was positive but tempered by pragmatic considerations about the future of paid search assistants.
