What Replaces Tettra in Microsoft Teams? 4 Wiki Options to Consider When You’re Migrating from Slack

Recently one team found themselves in a situation many growing organizations face. The teams decided to consolidate tooling and move fully to Microsoft Teams. At the same time, two companies merged:

• One team used a self-hosted wiki
• The other relied on Tettra and Slack

Everything seemed manageable until we discovered that Tettra’s integration with Microsoft Teams was no longer supported in any meaningful way. It was previously available in a limited way, as an AI Bot, but now it isn't even present in the Teams app store. There was no native experience inside channels. No seamless search.

That’s when the real question emerged: What wiki alternatives actually work well inside Microsoft Teams?

If you’re migrating from Slack and relied on Tettra for knowledge management, you’re probably asking the same thing.

What’s Happening With Tettra in Microsoft Teams?

Tettra was built primarily as a Slack-first knowledge base. While it previously experimented with Teams integration, today:

• It has no strong native presence in the Teams app marketplace
• There is no seamless in-channel knowledge experience
• Search and bot-based surfacing are limited compared to Slack

At the same time, Microsoft retired the original Microsoft Teams Wiki. Microsoft shifted users toward tools like:

• Microsoft OneNote
• Microsoft Loop

While useful, neither provides a structured, scalable knowledge base in the way many teams expect from Tettra.

The Impact

For teams that relied on Tettra inside Slack:

• Knowledge is no longer embedded in daily chat workflows
• There’s no centralized, searchable system inside Teams
• Documentation risks becoming fragmented again
• Tools designed around Slack’s ecosystem (like Tettra) lose much of their value when moved into Microsoft Teams

And that’s dangerous. Knowledge management only works when it lives where work happens.

What to Look for in a Tettra Alternative for Teams

The team started their own research and evaluated replacements, they focused on:

• Seamless integration inside Teams (tabs, chat, search, bots)
• AI Chatbot features
• Powerful, fast knowledge search
• Easy onboarding for merged teams
• Clear content ownership and structure
• Smooth migration from Tettra and old wiki to Perfect Wiki
• Cross-team collaboration support
• Opportunity to continue the work in Slack during the transition period

With those criteria in mind, here are the best options.

Top Wiki & Knowledge Base Alternatives to Tettra in Microsoft Teams

Perfect Wiki 

The first option the team came across was Perfect Wiki and it actually appeared the best among other platforms on the market and here's why.

Perfect Wiki is built specifically for Microsoft Teams. It operates inside Teams channels and chats. 

Why it stood out:

Perfect Wiki's main advantage for this particular use case was the native integration in Microsoft Teams, so all the documents could be stored in one space with easy access. The users also appreciated the SSO via Microsoft, that was vital for them after the migration.

Next priority was the powerful search engine and AI Chatbot feature, both present in Perfect Wiki. The ChatBot allows to search for content quickly and is accessible through the personal tab, chats and channels. All that allows to facilitate the onboarding process, as well as speed up Q&A workflows inside the team, that is urgent after the merging process.

One more point that mattered was the structured article hierarchy. After merging two bulk archives of the both companies - it was vital to create a clear structure, set verification dates for the documents, manage levels of access, define ownership for different content bit. Perfect Wiki has it all.  And through the advanced analytics reports, the Admins can easily track the knowledge base performance, identify knowledge gaps and manage the documentation effectively.

Of course the migration process itself was as important as the final result. It had to be smooth, swift and preserve all the content bits from both of the merging companies. Perfect Wiki import feature really nailed that task! The team members were able to migrate content both from Tettra and old self-hosted wiki in a couple of clicks, with minimal assistance from the Perfect Wiki support team. Just needed to fulfill the exports from existing solution and upload everything in bulk to Perfect Wiki. 

Perfect Wiki was initially designed to replace both Teams Wiki and Slack-based tools. However, it still offers its own Slack integration, so for those users who still have to work through Slack - Perfect Wiki content will be accessible via the AI Bot integration. And as the former native workspace is available - it really boosted the adoption process.

As the team's goal after merging was to centralize everything inside Teams - not in a separate app - this appeared to be the most natural replacement for Tettra. The company was able to migrate both from the self-hosted wiki and Tettra easily. This new step of their business was smooth and successful thanks to the Perfect Wiki rich features, native Microsoft Teams integration and intuitiveness. 

However, let's review other available options. They didn't prove to be as efficient when integrated into Microsoft Teams but still can be assessed as possible options.

Confluence

Confluence is a mature, enterprise-grade wiki platform by Atlassian. It really has powerful permissions and advanced documentation structure, as well as strong search capabilities. However, when having the particular use case of moving away from Tettra + Slack into Microsoft Teams, it feels less native inside the environment. In Microsoft Teams Confluence is downgraded to a simple search bot and the users still had to run a web app to work on the documents or read the articles. Against the background of a merging process, that seemed heavy and inefficient. So, Confluence was not an option here.

Though Confluence does integrate with Teams, it still feels like an external system. You can read the full comparison of Confluence and Perfect Wiki here: Confluence vs Microsoft Teams: Best Knowledge Base Tool for 2026?

Guru

Next app under revision was Guru. It works well across tools and offers browser extensions and verification workflows, has a proper search and AI capabilities. The feature kit is rather abundant as well. However, it has stronger Slack support (just like Tettra) than Microsoft Teams and a less hierarchical documentation structure.

In Microsoft Teams Guru also functions as bot and not a full-fledged wiki/knowledge base solution. For the case under revision - Guru was not a viable Tettra alternative for Microsoft Teams. You can find the full overview of the Guru integration here.

Slab

Slab was the last option the team reviewed before the merging/migration process. It is easy to use and focuses on the knowledge clarity, so it required a minimal learning curve. Nevertheless, just as Confluence and Guru it is not deeply Microsoft Teams-native. Slab’s Microsoft Teams integration is lightweight and connector-based. You can receive notifications in Teams when content is published or updated, share Slab links into Teams chats, add Slab as a basic web tab.

Most editing and navigation still happens in the Slab web app, meaning users must switch between tools often, not ideal for Teams-centric organizations. So, again, not a fit for the Tettra migration use case. See the full overview of the Slab integration here. 

After all the searching and assessment processes, the answer was clear - Perfect Wiki was the go to solution. It offered the native Microsoft teams integration, all the necessary features, smooth import and intuitive onboarding. Now let us get a bit deeper into the process of migration from Tettra.

Migration Process from Tettra  to Perfect Wiki

After the solution was chosen and assessed properly, it was the time for the main thing - migrating the documents from the old sources: Tettra and a self-hosted wiki. The process appeared to be smooth and easy due to the Perfect Wiki's bulk import options and user-friendliness.

Here’s what actually was done:

Step 1: Audit Existing Knowledge

Both teams had to identify the critical content in the self-hosted wiki and Tettra, review the articles and remove outdated entries, as they didn't have to bring the outdated content to their new mutual business.

Step 2: Export Content

• Exported static pages from the old wiki in HTML format
• Extracted structured knowledge from Tettra in HTML as well

Step 3: Import Into Perfect Wiki

With the help of the Perfect Wiki bulk import dialogu the users migrated the knowledge into Perfect Wiki directly inside Microsoft Teams. The whole process just took a couple of clicks.

Step 4: Reorganizing the Content

After the knowledge base in Perfect Wiki was filled in with the content from both sides, all that needed to be done was some restructuring, hierarchy levelling, assigning owners, setting tags and verification dates.

And that was it. The biggest win in the process is that the knowledge now lives where conversations happen.

Conclusion

This use case really showcases how a proper wiki solution can make any tedious process smoother. Perfect Wiki allowed the two large teams to merge their knowledge assets and step into a new phase of their business development in a completely new environment in no time.

So, if you relied on Tettra inside Slack, the shift to Microsoft Teams forces a decision. The most successful teams choose a Teams-native or strongly integrated knowledge base instead of stitching tools together.

If you’re planning your migration, now is the right time to redesign how knowledge works in your organization - not just where it lives.

Plan your migration carefully. Audit before importing. And choose a solution that fits Microsoft Teams - not Slack.
