Search insights have reduced no-result queries and guide visitors quickly to relevant content
In my opinion, the best features Coveo offers are that it's quick, it's easy to navigate, and if you have something you want to know, Coveo is very helpful in helping you find out how to get the information that you need and sort the information that you need. Of those features, the main thing I find myself appreciating the most in my day-to-day work is being able to find what I need without spending a huge amount of time. The speed and easy navigation are important; there are other tools that do the same thing, but finding what I need quickly really matters.

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

"One of the standout features of Coveo is its AI-powered search relevance, which helps users find the right content quickly."
"I would highly recommend Coveo as it is smart, fast, relevant, and especially suitable for big sites and large e-commerce setups."
"What we are seeing is that our sales have significantly increased by twenty to thirty percent just within one year of using Coveo."
"Coveo has positively impacted my organization by cutting down the number of no result searches from something like 15% to about 5%, which is huge, saving calls to call center people and probably preventing people from seeking out products from our competitors, so we get people to pages that they want more quickly and more effectively."
"The biggest positive impact Coveo has made on my organization is reducing the time people spend manually searching across different enterprise systems."
"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."
"Coveo is scalable and I have not seen any latency issue."
"Coveo already has a very good e-learning platform with multiple courses to learn and certifications to achieve, so it is very good in terms of the learning curve for new users or developers working with it."
"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."
"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 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."
"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."
 

Cons

"I think Coveo can be improved by providing a sandbox for developers, even if you are not part of an organization, and the API configurations can be made a bit easier because there are a lot of options right now which confuses users."
"The main reason I rate it an eight out of ten is that while Coveo is very capable, there is still some room for improvement regarding the developer experience."
"Coveo can improve by supporting a few more languages."
"I think the pricing was definitely on the higher side, and the professional services were also quite costly."
"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."
"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 other suggestion is that as of now, the sync between our Salesforce and Coveo is one hour."
"One area of improvement for Coveo is the size limitation concerning response results."
"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."
"There are probably other chatbots out there that were built for specific use cases and are easier to deploy than this."
"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."
"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. 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."
