Chose Flock
Many of the features are shared between these three programs but for us, we found the mobile application to be much easier to manage and being that we were using this a lot on the go that was a major selling point for our team and operation.
Chose Flock
In my opinion, Flock is not the best among the listed products in terms of extensive features that other products listed provides but has it's own place in the communication and team collboration domain. I think Flock works well for smaller teams and organizations looking for a …
Chose Flock
Flock stands strong with these tools in market. Although it does offer some great features but can be better in terms of integration.

We used Flock for over 10 years in our organization because it was easy to use for non technical users.
Chose Flock
Flock stands up very well against others when used for individual and group chats. It also works well with Google Drive Integration. The best part of Flock, compared with others, is in the area of File and Document sharing. The two areas it slightly lacks are voice/ video calls …
Chose Flock
Slack and Flock are fairly comparable in terms of features, though Flock has a cost advantage.
Chose Flock
I mainly prefer Asana as a task management tool, but I prefer Flock to Slack for communication. Flock bridges the gap between the two, and I find it's the best niche is for businesses or collaborators who need some integration (drive or calendar) but mostly need it for its chat …
Chose Flock
Flock as mentioned takes the best of all these apps and improves upon them. Flock's UI was exactly what we were looking for and Flock doesn't overcharge small teams for search functional or messaging. It just offers a great product at a great price combined with great …
Chose Flock
Unlike Flock which is more official, Google Hangouts are geared towards personal communication rather than business. Flock on the other hand has many features which relate to business setting
Chose Flock
I did not like Google Hangouts. Hangouts is more geared toward personal communication instead of business related communication. Flock is also a lot easier to use and has more options related to a business setting.
Chose Flock
Our creative team collaboration pathway story went like this..We started on Facebook as a secret group. We looked for better solutions and moved to Google Docs. It was a bit too robust for smaller conversations, so we moved to flock. Flock was great but proved to be too much …
Chose Flock
Flock is similar to Glip, with only two notable differences: the gifs are worse but the reactions are slightly better. Integrations are a little better, albeit a bit confusing. For example, there is a built in video conferencing feature where you can video chat with someone, …

The single thing that causes Guru to win is their Chrome extension. It's the most useful thing about Guru and every other competitor that happens to have one doesn't support half the feature Guru does with theirs. Guru gets that information is best capture and retrieved where …
Chose Guru
I was not the decision maker in choosing Guru for our organization. However, previously we used Notion, and I can say that, compared to Notion, I find Guru far more user-friendly and capable.
Chose Guru
I have only used proprietary software in the past and it was not user-friendly. One process would have 3 to 4 documents and they would have conflicting information on each. Guru is a breath of fresh air.

I tried the trial period for several platforms before deciding on Guru. Ironically Guru, was recommended to me by Grok AI. I was expressing what platforms I had tried, what I was looking for, and asked for other options to explore. I was frustrated.
Ultimately what I really …

Other companies I have worked with use Google Docs. Google Docs is a little more difficult to use and doesn't offer as many options. Guru can also link to many major platforms so you can have the best of both worlds.

Although Document360 is an internal knowledge base like Guru, in Guru the card format is much more helpful. The card-based search facilitates access to advisors. It's also a tool that greatly facilitates use for new users who aren't yet familiar with the workflows. Without …

In Salesforce, it's hard for me to find or navigate specific knowledge base. Unlike in Guru, it's easy to access and navigate specific concern or keywords in every concern. I'm glad that we have this tool. It wouldn't be hard for us to do every tasks that was assigned to us and …

Previously I used the Help Panel within Salesforce as a knowledge base for clients. Once I had the privilege of trying Guru I have not been disappointed. It has been a very pleasant experience. The interface is better visually. There were more user friendly options. Its a …
Chose Guru
I prefer Guru as you can search multiple entries at once and not lose the original search.
Chose Guru
I have not reviewed other ones, Guru is the first one that I have seen like this. I have used other ones, like Salesforce that has a knowledge base but it is not like Guru. I think AI is a great feature to be integrated into a knowledge base for businesses.
Chose Guru
While I don't have experience with other products like GURU, I can say that GURU is a very useful website if you want to find information and keep them well-organized, saving you time and hassle of going through it one by one. It also has features that you can easily use and …
Chose Guru
I was not involved with the selection process, but as a user, I found that Confluence was clunky to navigate, and the information quickly became out of date - there weren't prompts to update it, so no one ever did.
Chose Guru
seems to be more user-friendly/up-to-date so overall more functional for our companys goals and values

No comparison Guru stays on point, in my opinion, einstein had a lot of glitches it needs to fix
Chose Guru
The platform is unique, comprehensive, and uses AI. These are standout features. I also like the verification process and the ability to search from anywhere or on any browser. Guru enhances productivity and knowledge transfer when someone leaves an organization. Guru's …
Chose Guru
Much better for knowledge management - although SI had other functions like creating coaching and tracking QA

The Archbee is a great app too but I will recommend Guru more since the Guru app supports all audiences and is offering API too. In addition to that, there are training webinars that is present in Guru as well that is not present in Archbee. Lastly, Guru app have AI features …
Tettra
Chose Tettra
Although most of the tools listed above are not dedicated wikis, they do offer that feature. I like that Tettra is dedicated to the wiki space, so that allows them more time to flesh out the features for that space.
Chose Tettra
Both products are comparable. our company allows a certain number of similar products, so we use both for different teams.
Chose Tettra
Tettra provides an easy interface, but feels limited in its feauture set. When I need to incorporate more granular permissions or live collaboration I use google drive.

Flock is a great communication tool. However, it's in a very competitive space. It offers seamless app integration (i.e., google calendar and drive) to allow for easy use across the platform. It's a great communication tool. However, if you don't need an overloaded app, there are other options out there. And for work purposes, it only covers some of what you need.

I think Guru is well-suited to organizations with subject matter experts committed to maintaining documentation. Guru cannot be managed by a single admin. It's essential that the SMEs are on board and are expected to participate in Guru as part of their role responsibilities. I'm not sure how well Guru would work for larger organizations with more information to house. I've only ever used Guru in SMBs with about 250 employees. It works well for that size.

Tettra is well suited as a repository for company information but can get cluttered quickly if used more broadly and dynamically. It is helpful for documents with wide permissions, and for disseminating information that’s owned by specific people.

Pros
  • Networked phones are a thing of past now. We don’t have to stop what we are doing to receive phone calls currently because Flock can do that
  • It is now easy to send messages to many people at the same time, all we need to do is to add all the contants in the chat and select all to send a message
  • This software has an in-built to-do-list which allows us to assign tasks to different people or users and then supervise each independently

  • Easy to learn. Anyone can make cards and use the AI to make them professional.
  • Answer questions about my business, essentially a wiki for everything we do.
  • The research mode is amazing. Full reports on various types of information including some rather complex topics. Complete with citations of where the information came from.
  • Admins can manage a hierarchy to keep information secure and available to the correct people.

  • Easy to use.
  • Easy to set-up.
  • The free version has basic integration options.
  • For the paid plans nice extra features (ie API).

Cons
  • A tool is only good if people use it. Some of the artists I work with found it too complex (though I don't think they really gave it a good shot).
  • We used it heavily for about six months and it didn't hit too many other big negative points.
Read full review
  • Formatting has always been a pain point for me. We used Google Sites previously, and the ability to add multiple columns of smaller content boxes was great. To do the same thing in Guru, you need to create a table, which constrains you.
  • While the AI functionality is great, it can be challenging at times to refine the responses. Specifically, you must edit the source that is being pulled rather than the response itself. In some cases, we've edited the source to make the answer as clear as possible, and even after multiple attempts, the populated answer was acceptable but still not ideal for minimizing confusion.
  • Sometimes, when adding content, the cards glitch, and it won't save. Or if I go to add something to a landing page, it says it couldn't be saved. Then I do it all over again, and it works.
  • While the cards have limited formatting, the landing pages are great; however, when trying to move around or adjust the content boxes, it can be hypersensitive and very tricky to work with.

We would likely to renew use of Flock for our organization since it meets most of the requirements of team collboration and communication for a small group like us. Most of our Flock users like it's features and use it extensively for day-to-day work. We are quite optimistic about it's future updates.

It is good to give what an app deserves, Flock is very efficient and effective app to manage the all day to day activities and communicate across all team members, create groups, share files, send reminders schedule reminders for each group or persons and share notes.Pin files and search any messages from anyone with advanced filters. It's a great app.

While using the GURU card, the level of response I get is quality. The rate at which my responses and prompts through the search or chat is fast, responsive, and high-quality. I can easily see when the cards were modified, who modified them, and the new information available on the GURU.

Reliability and Availability

Highly reliable day‑to‑dayGuru is consistently available when I need it. The platform loads quickly, search works reliably, and I rarely experience downtime or slow performance. It’s dependable enough that teams can trust it as a daily source of truth. Minimal unplanned outages or errors. In my experience, unplanned outages or errors are extremely rare. Even during high‑usage periods or heavy workflows, Guru remains stable and responsive.

Performance
No answers on this topic
Pages load quickly and consistently. Guru’s interface is lightweight, so cards, boards, and search results load fast with very little lag. Even when navigating between collections or opening larger cards, performance stays smooth and reliable. Integrations perform well without slowing systems down. Using Guru through the browser extension or Slack integration doesn’t noticeably impact performance. Cards surface quickly, and interacting with the integrations feels just as smooth as using Guru directly.

Support Rating
We've only needed customer support a few times with Flock (mainly concerning app integration and security), and they've always been timely and helpful, which are the only things I truly need from support. The response rate was still rapid, and there's plenty of support available online as well for Flock.

The only reason I do not give it a a ten is because I think there is still some room for improvement in meeting the different time zone needs of their customers, but overall their support is top notch. Friendly, capable, and quick.

I base the rating on the online availability of the help system. The product is quite intuitive but the questions I did have were answered on the online help. That is always better than having to contact support as then you have to wait longer than just a search on the website.

I would rate the online training for Guru a strong 8 out of 10. While it lacked the interactive nature of in-person sessions, the content was well-structured and delivered effectively. The training modules were clear and comprehensive, covering all essential aspects of using Guru. The flexibility of online training allowed me to learn at my own pace and revisit topics as needed. Overall, it provided a solid foundation and practical understanding of Guru's functionalities, making it a valuable learning experience despite the virtual format.

Return on Investment
  • Organizing notes manually has been drastically reduced. Flock folders and chats are perfect for keeping each file separate.
  • We have not missed one calendar event with Flocks integration of our Google Calendar.
  • Being able to cut out or $99/month case management software has saved a ton of money each month.

  • The small support team can reliably scale to cover a broad swath of Tier 1 topics while maintaining decent first-response times, even when experiencing record-breaking, forecast-exceeding ticket volumes (e.g., 4 FT and 1 PT agents managing 880 tickets in one week).
  • Tier 2 topics (e.g., Billing and Technical) that require specialized attention and are "owned" by a specific agent can be written and validated by that agent's manager. The team manager can utilize that to cross-train should the agent leave the company or be out of the office.
  • Seeing my team's ebb and flow of weekly/monthly Guru engagement, as well as validation percentages in comparison to the ebb and flow of our ticket volume and production releases, helped me to communicate with C-suite leaders the necessity of having a margin of time to implement AI Agents and integrations in order to continue to scale.
