Stable, scalable, and has testing and conversational AI features
The total time it takes to deploy IBM Watson Discovery depends on the documents you'll be working with. For example, I was in a situation where I was working with some painting files and folders for a painting store. The store had PDF documents, but the information was mixed up, so I had to treat the documents on IBM Watson Discovery, and discovering and understanding each PDF file took longer. The process is more straightforward for plain documents, and you have to work with questions that will help IBM Watson Discovery understand the documents. The time to deploy the product depends on the quantity and type of documents you'll be working with.

Higher conversion rates with an advanced algorithm and intuitive interface
An area for improvement is the interface language, as our team mainly speaks French. Offering a French-language option would significantly enhance accessibility and streamline usage. Additionally, simplifying interactions with the Luigi's Box team, such as through localized support or tools tailored to non-English-speaking users, would improve collaboration. These changes would ensure a more seamless integration of the solution into our daily operations.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature of IBM Watson Discovery is testing, mainly because the product applies conversational AI, which means I can ask questions to get the information I want from a specific test area."
"Being able to have some rules to extract the entities is valuable."
"The most valuable features of IBM Watson Discovery are the integration with the rest of the Watson Suite and the Watson Assistant capability. If you use Watson Assistant, the ability for it to be able to determine the accuracy of your voice models and your voice response systems is a benefit."
"Being able to have some rules to extract the entities is valuable. The capability to crawl external sites and internal documents, and then draw internal information with external contents is also valuable."
"It has allowed us to provide longer service availability for support to users."
"Language support and the ability to build a natural language of speech recognition are the most valuable features."
"The most valuable features of IBM Watson Discovery are the integration with the rest of the Watson Suite and the Watson Assistant capability."
"Luigi's Box was easy to implement and allowed me to get started quickly."
"With its advanced algorithm and intuitive interface, this tool makes setting up the product feed simple and efficient."
"Thanks to this solution, we’ve seen a significant improvement in our conversion rate (CVR) compared to last year, proving its effectiveness in driving performance and optimizing results."
"This smart search capability significantly reduces the time customers spend searching for products, as it anticipates their needs and suggests the most pertinent results."
"In analytics, we can see what our visitors can't find with us, because we can look in history to see what products they wanted to search for and couldn't find. We can see the exact number of people who wanted to find something."
"Within the dashboard, the application offers data analysis that works with different views of the customer data. This data is graphically processed and thus does not need to be further modified for better interpretation."
"Luigi's Box is helpful in implementing even non-standard requirements."
"Its seamless integration with existing platforms streamlines workflows, making it an indispensable tool for businesses of all sizes."
 

Cons

"IBM Watson Discovery has moved to a newer version and it is very difficult to train the newer version."
"It needs a lot of memory. Our index is very big."
"It needs a lot of memory. Our index is very big. It is around 100 gigabytes. So, we need more than 100 gigabytes of memory to use Watson."
"The support from IBM Watson Discovery is good but could improve to make it great."
"There are probably other chatbots out there that were built for specific use cases and are easier to deploy than this. Having said that, Watson is way more flexible. While it may require a greater amount of effort, it is not substantially more than some of the other ones that are kind of prebuilt for a specific use case. It would be good to have more prebuilt and specific use cases and specific business models. It can have better phone integration, even though I think that it is actually becoming less of an issue. Most people are online nowadays."
"There are probably other chatbots out there that were built for specific use cases and are easier to deploy than this."
"The pricing is an area for improvement in IBM Watson Discovery because the customer initially used the free version. Still, when he needed more questions and documents, he had to move to a different version, which was paid and cost $500 per month. That change in pricing made my company lose many customers."
"It could simplify the implementation on the website."
"More robust guidelines on optimization techniques would be highly valuable."
"Enhancing the reporting and analytics capabilities would provide us with deeper insights into user behavior and search trends, helping us optimize our offerings further."
"Our products are really diverse. Not everything can be done automatically, and manual intervention is required."
"We have been using the service for more than two years, and our experience is only positive."
"Integration with GA4 and a plugin integrating with Google Looker Studio would be very useful."
"Deeper use of AI and ML - although with the advent of AI, new features have been implemented into Luigi's Box, there is still room for deeper integration."
"However, we know that there's always room for improvement, and Luigi's Box has already made a lot of progress and it is still increasing its value and adding new features."
 

Pricing and Cost Advice

"IBM Watson Discovery is an expensive product."
"Cost-wise, it is very reasonable because it is cloud-based."
