Creating low-code agents has transformed policy queries and now saves employees hours daily
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.

Macros and automation have streamlined workflows and reduced manual effort across support teams
The ability to communicate on the Zendesk ticket through the actual user software, so TOPs, would have been helpful. Somehow seeing a user's ticket history within our app would have been beneficial. That is the only thing that I do not think existed at the time that might have been helpful. Some people struggled with Zendesk, but it was always easy enough to show them how to use it and what they were missing. The only times we really had people report concerns about it was when they did not understand that it could do that or how to use it in that way.

Quotes from Members

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

Pros

"Life became so easy when we started using Glean Platform."
"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."
"Glean Platform offers excellent user interface design and integration capabilities with other platforms."
"Productivity has really skyrocketed."
"The best features Glean Platform offers include the ability to create my own agents, for example, I created a self-service agent for my stakeholders, so rather than email me, I sent them a link to an agent where the agent asks them questions and drills down to exactly what they need, and then I get a qualified response from them."
"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 our organization, especially in terms of productivity for both us and our customers."
"Glean Platform has increased productivity by at least one hundred hours per week for my organization."
"Zendesk has positively impacted my organization primarily through security, as I do not have to worry about data breaches or leaks because all information is handled and processed through Zendesk, ensuring that only people within the organization can access it."
"We were able to get up and running with Zendesk in a very short time and build a robust web app including help desk functionality that makes the product owner and client very happy."
"If their price is acceptable, I would recommend using Zendesk to all companies whose clients and employees need a simple way of raising issues."
"The most valuable feature was its simplicity as it was made easy to use."
"Zendesk is a very good product."
"This is one of the better solutions on the market for SMBs."
"What is cool about Zendesk Guide is how it works together with others Zendesk products. Especially with support and with the analytics. Put those together for a small or medium-sized company and it's a really powerful tool."
"Just buy it."
 

Cons

"My experience with pricing, setup cost, and licensing for Glean Platform reveals limited options, and I wish there was more customization available."
"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."
"I tried pulling in an architecture diagram of a workflow, and it pulled in some other image instead."
"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."
"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."
"There are multiple ways in which Glean Platform can be improved."
"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."
"It could use better analytics for trend tracking as well as the ability to tie the customer support and sales items together."
"If I write an article, and I have a team of 30 people, and they all have a Zendesk account, when I write an article, I send them an email. "Hey guys, I just wrote this article. It's one of the most popular topics this month on which we are not covered. Please check it and make sure that you include it in your resolutions". The issue is, once I send it to those 30 people, and they open it, the next morning, that article is the most popular article."
"I would also mention that the Zendesk app on iOS is not very good."
"I would like easy access for the mobile app as it can take quite a while to load the data."
"As Zendesk is an international business and has customers world-wide, it would be nice if it would provide 24/7 support."
"The licensing model needs to be more customer-friendly."
"I really wish they had a chat feature - like Olark for example."
"The support is not on chat often which is quite frustrating if you want immediate answers but they do respond to tickets within 24 hours."
 

Pricing and Cost Advice

Information not available
"There are different plans that are offered. We are using the entry-level plan. The overall price of the solution should be reduced. The price is too high."
"We pay for the solution on a yearly basis and my understanding is that the cost is about $30,000. That's the cost for 24 to 25 agents."
"The price is very competitive."
"Zendesk's licensing is not cheap. For Enterprise, we are paying $200 per agent. It's a per-month cost, so it's pretty steep. There are some services you need to pay extra for. For example, with Zendesk Guide, we had to buy the most expensive offering in order to get Multibrand and everything. We also had to pay a lot of money for themes."
"You have to pay extra for better support. So it's not only the license that you pay for, but you have to pay extra for the support as well."
"From what I hear, Zendesk's pricing is a little expensive."
