Intelligent search has transformed our ecommerce personalization and drives higher conversions
Coveo fits into our workflow as the core engine of our search, which makes our users' experience amazing by providing us with insights on what products are being sold more and what kind of customers in what regions understand or require what kind of products. Those minimalistic details are what Coveo has provided us with and improved our website interaction. The best features Coveo offers include the AI-powered search that analyzes the region, the user, specific products, or preferences and needs, automatically sharing that information. Additionally, the search it provides is extremely fast and features an auto-search option that gives users basic details, images, and offers in the search field itself. The AI-powered search actually helps our team by allowing users to search for products based on their preferences, with caching available that makes the search fast for users. This has increased our throughput time and the number of users engaged with our application, leading to more purchases. The biggest feature I would highlight about Coveo is the AI enhancements and advancements they have made. Beyond that, the website search for products is faster, and we use it for some of our internal employee search applications as well, making it an amazing tool to utilize.

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.

Quotes from Members

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

Pros

"I would highly recommend Coveo as it is smart, fast, relevant, and especially suitable for big sites and large e-commerce setups."
"Coveo provides a search engine experience that is superior when compared to the other search engines available in the market as of now."
"AI-enabled query suggestions help users return more frequently and build trust in the search capabilities our site offers, allowing us to drive content towards users based on popular queries."
"What we are seeing is that our sales have significantly increased by twenty to thirty percent just within one year of using Coveo."
"Coveo provides AI-driven search results and proper recommendations based on customer interaction and context, which is very beneficial for us because it improves our order conversion rate, allowing customers to find the exact products they want and see similar products, greatly increasing upselling."
"Language support and the ability to build a natural language of speech recognition are the most valuable features."
"Being able to have some rules to extract the entities is valuable."
"It has allowed us to provide longer service availability for support to users."
"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."
"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."
"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."
 

Cons

"In a general sense, we are not seeing a remarkable return on investment because maintaining Coveo for our search functionality is costly, and we have to balance investments in search versus other areas."
"While Coveo is overall very fast, I find the development integration somewhat challenging."
"I chose eight out of ten because we have some limitations, such as when we share heavy data, where a large number of data takes more time for Coveo to process; that is one area where Coveo needs to improve, but apart from that, it is good."
"One area of improvement for Coveo is the size limitation concerning response results."
"I would give Coveo a nine out of ten because the response and everything is fine, but the technical team of Coveo helps us, yet I think it is not one hundred percent."
"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 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."
"IBM Watson Discovery has moved to a newer version and it is very difficult to train the newer version."
"There are probably other chatbots out there that were built for specific use cases and are easier to deploy than this."
"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."
"The support from IBM Watson Discovery is good but could improve to make it great."
