Glean Reviews & Product Details

Glean’s context awareness sets it apart from the other enterprise AI tools we use internally. It’s also the most token-efficient option we have for helping our internal customers get their work done. On top of that, I really appreciate that we can implement new features ourselves, directly, without needing professional services. Review collected by and hosted on G2.com.

There isn’t much I dislike about the technology. If I had to point to one area for improvement, it would be the maturity of some of the sharing options for Glean native artifacts. There have been times when we’ve wanted to share items with a group that already exists in Glean, but we haven’t been able to. Review collected by and hosted on G2.com.

I like that Glean has a clean, intuitive interface and makes it easy to find information without jumping between different tools. The integrations are a big plus because it brings information from multiple systems into one place. It’s also quick and reliable in day-to-day use, and the time saved searching for information makes the ROI pretty clear. The onboarding was straightforward, which helped me start getting value from it quickly, and the AI-powered answers make it much easier to get to the information I actually need. Review collected by and hosted on G2.com.

The main thing I’d improve is the consistency of search results, especially when looking for very specific or less common information. Some integrations can also take a little time to get fully set up and configured. From a pricing/ROI perspective, it can be harder to justify for smaller teams, so the value is much more noticeable at a larger scale. Onboarding is fairly smooth, but better guidance around advanced features would make the experience even better. Review collected by and hosted on G2.com.

I like that Glean can access a multitude of resources at different places and find the exact information I'm looking for, which would usually take a lot of time. Glean cuts my search time by more than 90% compared to individually searching every document line by line. I've also found it excellent for creating wireframes or mockups for websites as it can easily access information using Jira. Additionally, Glean supports voice and chat functionality, making it easy to find what we're looking for. Review collected by and hosted on G2.com.

I feel Glean is limited by the information it can access. For example, my teammates have access to their GitHub, which provides them better knowledge, but it doesn't provide the same for me as it asks for my individual login. I think it should be able to answer API-related questions using information from GitHub, even though I don't have direct access. I often get stuck because I can't find the data size of attributes to set variable lengths, as this information wasn't available in the resources I had with my personal login.

I love Glean’s ability to work with my current tech stack at work and help me quickly pinpoint what I’m looking for. It also gives me helpful context around a question, or anything related to the question I’m asking, across all the integrated systems. Review collected by and hosted on G2.com.

The main challenge I run into is when there isn’t a native integration with a tool I need. That quickly becomes a hurdle, because I have to find a workaround to connect the tool so my teams can be fully successful. Review collected by and hosted on G2.com.

I like the fact that it's integrated with our company data so I can search how certain tools work with our product. What the buzz words used in some meetings mean. I like the fact that it's integrated with Jira and I can create agents to improve my productivity. Review collected by and hosted on G2.com.

I think there’s still some work that needs to be done. For example, I need to access eCRs (Emergency Change Requests) and CRs (Change Requests) from Service now, but Glean isn’t able to retrieve them. As a result, I have to manually download the list of CRs from Service now and then feed it into Glean to get my questions answered. Because of this, I see limitations to full automation, and when I ask about it, I’m told it’s because I need to code. Review collected by and hosted on G2.com.

1. Wide variety of LLMs/Models to choose from: It has helped us understand how each model responds, which model is suited for which specific task, and how to best make use of the available models

2. The ease of use via desktop app, browser extension, and mobile app has really helped use Integrate Glean into our day-to-day workflow

3. It has become very easy to build agents and like all AI it has reduced barrier to entry in-order to get to working agents which greatly improved our practices.

4. The integrations with native Microsoft app and other applications through MCP has really helped us add on our context and allow systems to talk to each other. Review collected by and hosted on G2.com.

There’s really nothing I dislike about Glean as a platform; it has consistently been helpful. That said, there are a few nuances with the AI: the responses aren’t always 100% accurate, so they shouldn’t be taken at face value.

A few features I’d like to see include added functionality and visibility for super-admins, autonomous web-browsing capabilities, support for more applications, and direct, explicit management of shared or group mailboxes. Review collected by and hosted on G2.com.

I love that Glean connects with Slack, Gmail, Calendar, and my drive, and I’ve used it effectively to search for just about anything across my entire organization. It’s much faster for finding answers and documents, especially compared to Google Drive search when I’m trying to track down something buried across hundreds of slides. I also used it to write my quarterly review by pulling together who I worked with and supported this quarter across email, Slack, and Drive. Review collected by and hosted on G2.com.

Sometimes it isn’t able to find the right resources. When that happens, I end up having to go to Slack and search myself, instead of it simply telling me it can’t find what I’m looking for. I also have to try searching again with different keywords to get it to show the right result. Review collected by and hosted on G2.com.

Glean provides a comprehensive search solution that integrates with multiple platforms like Confluence, Jira, Slack, Gmail, Salesforce, and GitHub. It offers permission-aware results and expertise discovery, making it easier for users to find relevant information and connect with the right experts. The tool is particularly beneficial for project managers, enabling them to quickly access historical data, streamline communication, and reduce redundant efforts. Review collected by and hosted on G2.com.

What I like best about Glean is having a single search bar that actually spans everything I touch day to day — Confluence, Jira, Slack, Gmail, Salesforce, GitHub, and more — instead of me remembering which silo a doc lives in and re-searching it five times in five tools. As a PM, I'm constantly pulling context (a stakeholder's history on an account, a prior decision buried in a Slack thread, a PRD from months ago), and Glean surfaces the right result with permission-aware ranking so I'm not wading through things I can't even open. The employee/expertise search is a quiet favorite too — "who actually worked on X" resolves in seconds instead of a round of Slack pings. Net effect: less time spent re-finding institutional knowledge, more time spent using it. Worth it for us — the time saved searching across tools easily outweighs the cost.

What I like best about Glean is how quickly it helps me find information across different workplace tools without having to search each platform separately. The AI-powered search understands the context of my questions and usually surfaces relevant documents, conversations, and resources within seconds. This saves me time, reduces repeated questions, and makes it much easier to find the information I need to complete my work. Glean provides good value for the cost because it reduces the time employees spend searching for information across different tools. The productivity gains are especially noticeable for teams that manage a large volume of documents and internal knowledge. Its value increases as more workplace platforms are connected and employees use it consistently. Review collected by and hosted on G2.com.

One area that could be improved is the consistency of the search results. Occasionally, Glean surfaces outdated or less relevant documents before the most useful information, especially when similar files exist across multiple platforms. More filtering options and clearer indicators showing when a document was last updated would make it easier to identify the most accurate result quickly. Review collected by and hosted on G2.com.

Connecting to business data sources is pretty simple. The governance model is great and makes my job as an admin easy. Its coverage over multiple data sources is great. The indexing really improves the quality of searching over Key resources. I'm so glad you released MCP as soon as we signed up - really helps for getting access to real-time information. Review collected by and hosted on G2.com.

Reliability is the biggest complaint. For a while they were collecting data on time saving but not returning it back to the user - essentially it'd be nice for glean admins to also be able to help debug to some extent. For instance, we had an issue with not being able to write through a certain field in Salesforce. The error didn't actually name the exact failure mode, and I could've fixed this issue with a little debugging. No one loves unexplained or silent failures. Reliability is definitely getting better! Some of the connectors are functionally not very useful. Like the Monday connector - I explicitly chose not to have it on and only use MCP - I know that there are benefits to both and in many cases, I leave indexing and MCP on for both use cases per data source for instance - but in this case, I explicitly turned it off. I'd like better quality control on that so less of the burden is on me to manage expectation and quality control for vendor-managed data sources and tools. Review collected by and hosted on G2.com.
