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.

What I would like to see is an ease by which I can have different connectors set up. Right now I have to do a lot of back and forth in order to have these connectors enabled. Having them by default on the platform would be very helpful for me. Also, when developing custom actions, having a developer portal where users can track the log of how the requests are being sent to custom endpoints created would be helpful because right now I do not have anything of that nature. It is just a final response that I get and it becomes very difficult to keep track of what is happening in the backend. Also, the latency that the platform offers is a little high right now. What I have noticed is that on a particular query, the user has to wait a long time in order to get responses. If there is a way to reduce this time and improve performance by decreasing the time for responses, that would be very good. I believe that the latency offered is a little high right now. If I can get prompt responses quickly, then that would be a real user experience enhancement. Also, what I have noticed is the problem that developers face when creating custom actions in Glean Platform, where we are not able to keep track of what is happening in the backend. A logger of sorts would be very good so that I can maintain an idea of what is happening in the backend. If that issue is resolved, along with also the issue of having custom connectors available from the start rather than going to Glean Platform and having conversations about the thing, then it would be very good. If these issues are resolved, then it would be a strong 10 out of 10 from me. But as of now, it will be an 8 out of 10. Glean Platform is a very capable platform. It is good for indexing documents and reducing manual workflows by incorporating an element of AI in it. Business usage can be increased as well. The one caveat is if there are developers who are creating actions on Glean Platform, then I must keep an eye on the logging that I have for the platform because interacting with the backend systems becomes very difficult using Glean Platform. Also, what I have noticed is that it is a real challenge in terms of latency as some of the responses may take a little while to load. However, what I have noticed is that the responses are usually very accurate, and so it is a trade-off between speed and accuracy. This is what I would advise to someone who is looking at Glean Platform.

Quotes from Members

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

Pros

"Coveo positively impacted our organization by drastically reducing the time needed to provide solutions on the support case side, as agents no longer have to sift through all documents, resulting in decreased response time and reduced case volume since customers can verify the knowledge available before creating a case."
"What we are seeing is that our sales have significantly increased by twenty to thirty percent just within one year of using Coveo."
"The biggest positive impact Coveo has made on my organization is reducing the time people spend manually searching across different enterprise systems."
"Coveo is scalable and I have not seen any latency issue."
"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."
"In terms of accuracy and reliability of output, I believe Coveo is probably the best in market scenarios."
"After migrating to Coveo, it took less than 10 milliseconds to load all this data."
"I have used many solutions, but Glean Platform is the best, and I would truly appreciate it if everyone considers this platform."
"When I searched for internal information spread across different systems, Glean Platform did centralize and retrieve that data for me effectively, giving me eighty percent accuracy."
"Life became so easy when we started using Glean Platform."
"Glean Platform has positively impacted our organization, especially in terms of productivity for both us and our customers."
"The best features Glean Platform offers are mostly the view, which I think is very good, and what I find most helpful about the view is that the user interface is very good, making it very easy to chat with the chatbot and get all the material that I want in the way that I need it."
"Glean Platform has increased productivity by at least one hundred hours per week for my organization."
"Since I have joined, I have built around ninety agents with Glean Platform, and it has saved our organization around twenty-seven hours a week for each user, and it has also positively impacted our ARR."
"Glean Platform has positively impacted my organization by speeding up a lot of repetitive tasks and making it easier for people outside of support to understand what kind of issues impact the support groups."
 

Cons

"The learning curve can be steep for new developers, especially when working with relevance tuning, query pipelines, and advanced configurations."
"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."
"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."
"One area of improvement for Coveo is the size limitation concerning response results."
"While Coveo is overall very fast, I find the development integration somewhat challenging."
"One other suggestion is that as of now, the sync between our Salesforce and Coveo is one hour."
"The main area I would improve is the learning curve because there are many concepts and configuration options, and understanding how indexing, query pipelines, security, and all those pieces work together requires experience."
"Coveo can improve by supporting a few more languages."
"Glean Platform can implement more models. The NLP creation could be a little faster, and while debugging is amazing, the routing also needs to provide higher quality outputs sometimes rather than extensive searching."
"Currently, Glean Platform does not integrate with Teams, Microsoft-owned platforms."
"Also, the latency that the platform offers is a little high right now; what I have noticed is that on a particular query, the user has to wait a long time in order to get responses."
"My experience with pricing, setup cost, and licensing is that the licenses were expensive, and it was hard to convince the company to adopt based on that."
"In workflow agents, I would prefer that we do not use AI in every step and instead we have a toggle button or something which can configure whether AI should be used in this specific search field or not, or in this specific node or not, because currently it's using AI in all nodes which sometimes messes up the output."
"I chose seven out of ten because if I could upload PDFs and have them analyzed, or have it integrate with my Gmail and help me go through my emails, that would be very useful, but I do not think it does that."
"I tried pulling in an architecture diagram of a workflow, and it pulled in some other image instead."
"Sometimes Glean Platform gets slowed down."
