What is a team knowledge wiki?
A team knowledge wiki is basically your company's brain, all packaged up in one searchable place. These apps bring together SOPs, onboarding docs, process guides, random tribal knowledge that usually lives in someone's head, and all the other stuff your team needs to actually get work done without pinging three different people on Slack.
Think of it this way: instead of hunting through old email threads, scrolling back six months in chat, or interrupting coworkers who are deep in focus mode, you've got everything documented and ready to go. New hire starts Monday? Send them the wiki link. Forgot how to file an expense report? Check the wiki. Need to know who approves what? Wiki's got you.
An SOP (standard operating procedures, for those who haven't worked in a place that loves acronyms) fits perfectly into these systems. Same with training materials, department handbooks, meeting notes that actually matter, project retrospectives, and those "how we do things here" guides that make the difference between a smooth first week and a chaotic one.
The best team wiki apps make all this stupidly easy to find. We're talking AI-powered search that understands questions like "where do I find the design files for the rebrand," not just keyword matching. Some even let you ask questions in plain English and pull answers from across your entire knowledge base, which honestly feels like magic when you're used to digging through folders.
What we focused on for this list: tools that teams actually want to use (not another dusty sharepoint that everyone avoids), search that doesn't suck, collaboration features that make sense, and ways to keep docs from going stale after three months when everyone forgets they exist.
How we picked these team wiki apps
Look, there's about a million "knowledge management" tools out there, and half of them are just glorified note apps with a team plan tacked on. We picked these six because they actually solve the problems teams run into when trying to centralize information.
First up: search needs to be fast and smart. If your team can't find what they need in under 10 seconds, they're just going to ask someone directly, which defeats the whole point of having a wiki. The best ones use AI to understand natural language queries, not just exact keyword matches. Slite's "Ask" feature is a perfect example - you can type "how do I submit PTO" and it finds the answer even if the doc says "vacation request process."
Document verification matters way more than people think. Half the wikis out there turn into graveyards of outdated info within six months. The good tools let you set review dates, ping document owners when stuff needs updating, and show when something was last verified. Nobody wants to follow a setup guide from 2026-2 that references software you don't even use anymore.
Collaboration features have to feel natural. Commenting, @ mentions, real-time editing, the ability to see who changed what and when. If it feels clunky, people won't use it. Simple as that.
We also looked at organization systems. Some tools use folders (boring but familiar), others use tags or channels or databases. The right choice depends on how your team thinks. Engineering teams might love Notion's database approach, while marketing teams might prefer Slite's channel-based structure.
Integrations count too. If your team lives in Slack or Microsoft Teams, your wiki better play nice with it. Same goes for Google Drive, Dropbox, and whatever other tools your company is married to.
Lastly, we cared about the actual writing and editing experience. Some of these tools have incredible features but the editor feels like you're writing in a text box from 2005. The best ones support markdown, embed media easily, let you create templates, and generally don't make you fight the interface just to document a process.
1. Slite
AI-Powered Wiki
Slite is hands down one of the smartest team knowledge bases out there, especially if you're tired of your team asking the same questions over and over. The standout feature here is Ask by Slite, which is basically ChatGPT but trained on your company's actual documentation. Type a question in natural language and it searches your entire knowledge base to pull together an answer. No more "hey quick question" messages interrupting people's flow.
The search experience in Slite is stupidly good. Fast, accurate, and it actually understands context. If you search for "vacation policy" it'll find your PTO docs even if they're titled "Time Off Guidelines." Small thing, but it adds up when you're trying to find stuff quickly.
Slite organizes everything into channels, kind of like Slack but for documentation. You can create channels for different teams (Marketing, Engineering, HR), projects, or whatever structure makes sense for your company. Each channel holds its own collection of docs, and permissions let you control who sees what. Great for keeping sensitive HR stuff separate from general company info.
The editor is clean and distraction-free. Supports all the basics: headings, lists, tables, code blocks, embedded images and videos. You can @ mention teammates to loop them in, leave comments on specific parts of a doc, and see edit history when you need to track changes. Templates help speed things up for recurring doc types like meeting notes or project briefs.
One thing that sets Slite apart is how it handles document freshness. You can set verification dates on docs, and Slite will ping the owner when it's time for a review. Super helpful for keeping your wiki from turning into a museum of outdated information that nobody trusts.
Integrations cover the usual suspects: Slack, Microsoft Teams, Google Drive, Figma. The Slack integration is particularly solid - you can search your Slite knowledge base directly from Slack, which means people don't even have to context switch to find answers.
Pricing starts free for small teams (up to 50 docs), then jumps to paid plans for bigger companies or teams that need advanced features like SSO and advanced analytics. Not the cheapest option on this list, but the AI search alone might be worth it if your team wastes hours every week hunting for information or answering repetitive questions.
2. Slab
Cleanest Interface
Slab bills itself as your company's entire brain in one place, and honestly, that's not far off. The interface is probably the cleanest on this list - simple, intuitive, no clutter. If you've got team members who get overwhelmed by complex tools, Slab is a safe bet.
The editor is fast and easy to use. Writing docs feels effortless, which matters more than you'd think. The less friction there is to create or update documentation, the more likely people are to actually do it. Slab nailed this. You can format text with keyboard shortcuts, embed images and videos, create tables, add code snippets, all without wrestling with the interface.
What makes Slab interesting is how it handles search and connected content. You can integrate Google Drive, Dropbox, and a bunch of other tools, then search across everything from one place. So instead of checking three different apps to find that spreadsheet from last quarter, you search once in Slab and it pulls results from everywhere. Saves a ridiculous amount of time.
Topics are Slab's organization system. Think of them like tags that help categorize and connect related docs. You can add multiple topics to a doc, making it easy to find from different angles. Way more flexible than rigid folder structures.
External bookmarks are clutch if your team references outside resources a lot. Instead of copying URLs into docs or keeping a separate bookmark manager, you can save external links directly in Slab with notes and context. Everything stays in one place.
Collaboration features are solid. Real-time editing, comments, @ mentions, the ability to request reviews from teammates. You can also see who's viewed a doc, which is actually useful for knowing if people have read important updates.
Integrations include Slack, Microsoft Teams, and the usual productivity app lineup. The Slack integration posts notifications when docs are created or updated, keeping everyone in the loop without them having to check Slab constantly.
Slab's pricing is straightforward: free for small teams, then a per-user monthly fee for larger teams. Not cheap, but not outrageous either. The clean interface and powerful search make it worth considering, especially if you value simplicity over having 500 features you'll never use.
3. Tettra
AI & Automation
Tettra takes a slightly different approach by building in a Q&A system alongside traditional documentation. The idea is that sometimes people need quick answers without reading through an entire process doc. They can ask a question, someone on the team answers it, and then that Q&A can be turned into proper documentation later. Pretty clever for capturing knowledge that might otherwise stay trapped in chat messages.
The interface is simple and gets out of your way. Creating docs is straightforward, with a clean editor that supports all the formatting you'd expect: headings, lists, images, videos, file embeds, tables. Nothing fancy, but it covers what most teams need.
Document verification is built in, which is huge for keeping your knowledge base trustworthy. You can set review dates on docs, assign owners, and Tettra will remind people when content needs a refresh. This prevents the classic problem where your wiki becomes a graveyard of outdated instructions that nobody trusts anymore.
The Q&A feature deserves a deeper look. When someone asks a question in Tettra, it posts to a dedicated section where teammates can answer. Once answered, you can convert that Q&A into a proper doc with one click. It's a smart way to reduce interruptions and build documentation organically based on what people actually need to know.
You can also assign teammates to docs, mention them in comments, and request feedback. Collaboration isn't quite as robust as Notion or Slab, but it covers the basics well enough for most teams.
Integrations are Tettra's strength. It connects to Slack, Microsoft Teams, Google Drive, and a bunch of other tools. The Slack integration is particularly good - you can search Tettra's knowledge base directly from Slack, and the bot will suggest relevant docs when it detects questions in channels. Cuts down on those "has anyone else dealt with this?" messages.
Pricing is mid-range. They offer a free trial, then charge per user per month. Not the cheapest option here, but the Q&A system and solid integrations make it a strong contender if you want something that meets people where they already work (i.e., in Slack).
4. Notion
All-in-one workspace
Notion is probably the most well-known tool on this list, and for good reason. It's insanely flexible - you can build pretty much any workspace structure you can imagine. The catch? That flexibility means there's a learning curve. Teams that invest the time to set it up properly love it. Teams that don't tend to end up with a messy, confusing workspace.
For team wikis specifically, Notion shines because you can create separate spaces for different teams or departments, each with their own structure. Marketing might have a wiki organized by campaign type, while Engineering has theirs organized by product area. Everyone gets what they need without being forced into a one-size-fits-all structure.
The editor is powerful. You can create docs, databases, kanban boards, calendars, galleries, timelines, all in the same workspace. For a knowledge base, this means you can have traditional documentation pages alongside databases that track things like onboarding tasks, tool inventories, or project timelines. Everything interconnected and linkable.
Notion's database features are where it gets really interesting. You can create a database of processes, tag them by department and category, add owners and review dates, then filter and view them in different ways. One team might want to see all their SOPs in a table, another might prefer cards with cover images. Same content, different views.
Templates are huge in Notion. There's a massive community sharing templates for everything from engineering documentation to HR handbooks. You can grab one that's 80% of what you need and customize the rest, saving hours of setup time.
Collaboration features are solid. Comments, @ mentions, real-time editing, page history. You can also set permissions at a granular level - some pages public to the whole company, others restricted to specific teams or individuals.
Integrations exist but aren't Notion's strongest suit. They've been improving this, but it's still not as seamless as some competitors. You can embed content from other tools and use Notion's API to build custom integrations if you've got dev resources.
Pricing starts free for individuals and small teams, with paid plans unlocking features like unlimited file uploads, version history, and admin tools. The paid plans are reasonably priced compared to alternatives. Just be aware that while Notion can absolutely work as a team wiki, it takes some effort to set up well. If your team isn't willing to invest that time upfront, you might be better off with something more opinionated like Slite or Slab.
5. Coda
Enterprise Ready Wiki
Coda is like Notion's more structured cousin. Same idea of an all-in-one workspace, but with more emphasis on building "docs that act like apps." If that sounds weird, think of it like this: instead of just writing static documentation, you can add interactive elements like buttons that trigger actions, tables that sync data between pages, and automations that keep things updated.
For team knowledge bases, this means you can create living documentation. Example: an onboarding doc that not only explains the process but also has a checklist that new hires work through, buttons to request access to tools, and a table that shows their progress. All in one place, all interactive.
The editor supports the usual formatting options, plus Coda's special building blocks: tables, buttons, automations, different views. There's definitely a learning curve here. Coda is more powerful than a simple knowledge base, but that power comes at the cost of complexity.
Templates help a lot. Coda has a gallery of pre-built templates for common use cases like team wikis, onboarding, meeting notes, and process tracking. Grab one, customize it, and you're most of the way there without building from scratch.
Collaboration works well. Real-time editing, comments, @ mentions, suggested edits. You can also create different team spaces within Coda, each with their own docs and permissions.
Keyboard shortcuts speed up navigation and editing once you learn them. For teams that love efficiency, this is a nice touch. Slash commands let you quickly insert elements without mousing around.
Integrations cover major productivity tools. You can pull data from Google Calendar, Slack, Gmail, and others directly into Coda docs, which is powerful for creating dashboards or keeping information synced across tools.
The big question with Coda is whether you need the extra power. If you just want a straightforward team wiki where people can write and find docs, Coda might be overkill. But if you want documentation that can also track processes, automate repetitive tasks, and act as a lightweight work management system, Coda's worth a serious look.
Pricing starts free for small teams, with paid plans adding more automation, larger file uploads, and admin features. Mid-range pricing compared to the list.
Which team wiki app should you choose?
So which one should you actually pick? Depends on what your team values most and how much time you want to spend on setup.
If you want the smartest search and AI-powered answers, go with Slite. The Ask feature alone is worth it for teams drowning in repetitive questions. Plus the interface is clean enough that everyone will actually use it.
For the simplest, cleanest experience with zero learning curve, Slab wins. It doesn't have all the bells and whistles, but sometimes that's exactly what you want. Get your team up and running in an hour, not a week.
Tettra makes sense if your team lives in Slack and you like the idea of combining Q&A with traditional docs. The Slack integration is tight, and the Q&A-to-documentation workflow is clever for building your knowledge base organically.
Notion is the move if you want maximum flexibility and don't mind investing time in setup. Great for teams that need a wiki but also want databases, project tracking, and other features in the same workspace. Just be ready to spend some time learning the tool and building out your structure.
Coda fits teams that want their documentation to do more than just sit there. If you like the idea of interactive docs with buttons, automations, and data that syncs across pages, Coda's your pick. Probably overkill for a basic wiki, but powerful if you need it.
Budget-wise, most of these have free tiers that work for small teams. Once you scale up or need advanced features, you're looking at $6-12 per user per month for most tools. Notion tends to be on the cheaper end, Slite and Tettra are mid-range.
One more thing to consider: how much does your team care about document verification and keeping content fresh? If that's critical, prioritize tools with built-in review reminders (Slite, Tettra, Notion with some setup). If your content doesn't change much, it matters less.
What makes a great team knowledge base?
Now that we've covered specific tools, let's zoom out and talk about what actually makes a team knowledge base work. Because honestly, the tool matters less than how you use it.
Outstanding search is non-negotiable. If finding information takes more than a few seconds, people will just interrupt their coworkers instead of checking the wiki. The best tools use AI to understand natural language questions, not just keyword matching. Slite's Ask function is a perfect example - you can ask "how do I file an expense report" and it finds the answer even if the doc is titled "Expense Reimbursement Policy."
Document verification keeps your wiki from rotting. Every team has experienced this: you find a setup guide, follow it step by step, and nothing works because it's from two years ago and half the steps are outdated. Good knowledge bases let you set review dates, assign document owners, and send reminders when content needs updating. This turns your wiki from a static archive into a living resource people actually trust.
AI is becoming huge for team wikis, though it's not essential yet. Tools like Slite use AI to answer questions using your team's documentation as context. Instead of searching for docs and reading through them, you ask a question in plain English and get a direct answer. For teams dealing with lots of repetitive questions, this is a game changer. Reddit's productivity communities are split on AI features, but I'm seeing more teams embrace it as the technology improves.
Easy editing matters more than fancy features. If creating or updating a doc feels like a chore, people won't do it. The best tools have editors that get out of your way - fast, intuitive, supporting basic formatting without making you fight the interface. Notion and Coda are powerful but have steeper learning curves. Slab and Slite are simpler but still capable.
Integrations determine whether your wiki becomes a ghost town or a daily-use tool. If you can search your knowledge base from Slack, embed Google Docs, and pull in content from other tools, it becomes a hub instead of another tab people forget to check. The more friction you remove, the better adoption you'll get.
Organization structure needs to match how your team thinks. Some teams love hierarchical folders, others prefer flat structures with tags, others want database views they can filter and sort. There's no one right answer - pick the tool that matches your team's mental model.
Finally, permissions and access control matter for protecting sensitive information. HR docs, financial data, client contracts - not everything should be visible to everyone. Good knowledge bases let you control access at the page or section level without making it complicated.
Final thoughts on team wiki apps
Team wikis solve a real problem: the constant interruptions, the knowledge trapped in people's heads, the time wasted hunting for information that should be easy to find. Pick the right tool for your team's needs, take the time to set it up properly, and actually maintain it. That last part is key - a neglected wiki becomes worse than no wiki at all.
For most teams, Slite or Slab are safe bets. Clean, focused on the core use case, and not overwhelming. If you need more power and flexibility, Notion or Coda deliver, just be ready to invest the setup time. And if your team practically lives in Slack, Tettra's tight integration makes it worth considering.
Whichever you choose, the real work is getting your team to actually use it. Start small, document the things people ask about most, make it easy to contribute, and keep content fresh. A mediocre tool that everyone uses beats a perfect tool that sits empty.
