Kendra has a nice AI built-in, enhancing the search experience and highly stable solution
There are many valuable features. For example, there are many documents that contain a lot of legal information.

We have multiple documents, so we don't know which document has the sought-after information. Therefore, we want to perform an enterprise search on it. So there are a lot of use cases we are trying to build using these newer technologies, specifically Kendra. Moreover, Kendra has AI, which has an upper edge, and that is really helpful. It has a nice AI inbuilt, which improves the search part of it.

Cons

Pricing and Cost Advice

"The pricing falls in the medium range."
"The solution is affordable."
"The cost is comparable."
"I would rate the pricing an eight out of ten, where one is the low price, and ten is the high price."
"​When telling people about the product, I always encourage them to set up a new service using the free pricing tier. This allows them to learn about the product and its capabilities in a risk-free environment. Depending on their needs, the free tier may be suitable for their projects, however enterprise applications will most likely required a higher, paid tier."
"I think the solution's pricing is ok compared to other cloud devices."
"For the actual costs, I encourage users to view the pricing page on the Azure site for details.​"
