Best Tettra Alternative in 2025

Tettra has been a popular pick for teams that live in Slack and want a simple place to dump answers to the same five questions everyone asks every week. It’s an AI-powered internal wiki that pulls in your Google Docs, answers questions right in Slack with its bot Kai, and nudges people to keep content fresh. For small to medium teams who love tight Slack integration and don’t want anything complicated, it’s genuinely nice. Setup is fast, the editor is clean, and that little AI answer box feels magical the first fifty times you use it.

But “nice” and “good enough for now” are two different things. As teams grow, budgets tighten, and AI will get dramatically better in 2026, many companies are realizing that Tettra is starting to feel like the bicycle they’ve outgrown. The cracks show up once you go past 50–70 people, or if you want something that actually feels like yours instead of a generic SaaS template.

Let’s look at the real pros and cons of Tettra in 2025, and then we will discuss an alternative that keeps making Tettra customers switch.

What Tettra Does Really Well

Tettra is legitimately easy. You can spin it up in an afternoon, connect Slack, and people start using it the same day. The Slack bot is excellent; ask a question in any channel and Kai usually gives a decent answer or points you to the right page. Content verification workflows are simple but effective: someone writes something, an expert verifies it, and stale content gets flagged. For teams under 50 who already live in Slack and Google Workspace, it feels frictionless.

The page editor is straightforward, categories and folders work fine, and the AI features added in the last couple of years (page summaries, FAQ generation, tagging) are mostly useful. If your knowledge base is under a few hundred pages and you never want to think about servers, Tettra may not be a bad tool for you.

Pain Points of Tettra

Here’s what customers actually complain about once the honeymoon ends.

Pricing hits like a truck when you grow. Even the Basic plan is $5 per user per month with a 10-user minimum. The Scaling plan everyone actually needs for proper AI jumps to $10 per user per month (again, minimum 10). A 100-person company is paying $1,000/month or $10,000/year just to have access. The Professional plan with SSO and proper onboarding starts at $7,200 a year for the first 50 users, then keeps climbing. Suddenly that “simple” tool is one of your bigger software bills.

Search gets weird once you have real volume. Users regularly say the same thing: that it works great until about 500 pages, then finding anything becomes painful. The AI helps, but it’s still searching Tettra’s index, not the full power of modern embeddings or vector search.

Customization is basically nonexistent. You’re stuck with Tettra’s templates, fonts, and layout. Want your own branding, custom domain, custom navigation, or to embed things properly? Tough luck. Want to add a custom field, workflow, or integration beyond the handful they support? You can’t.

Permissions are basic. You get owner, admin, member, and that’s pretty much it. No granular page-level or section-level permissions without awkward workarounds. Good luck if you have contractors, different departments, or any complexity.

No real multi-language support beyond basic translation plugins that kind of work.

You are vendor locked to a degree. Exporting your content is possible but messy. Everything lives in Tettra’s format, and migrating out later is difficult.

The content editor is still quite limited compared to modern wikis. Tables are clunky, embeds are hit-or-miss, no native diagrams, no proper databases, or linked references.

In 2025, when AI is everywhere, Tettra’s AI feels… fine. It’s good at answering simple questions from your existing pages, but it’s not getting smarter the way open platforms are.

Why Teams Are Quietly Leaving Tettra This Year

Many users that are leaving Tettra start looking for something that:

Doesn’t charge per user
Scales to thousands of users without issues
Lets them own their data and branding
Has modern AI that keeps improving
Easy to customize

Conclusion: Tattra or MediaWiki?

Tettra remains a solid choice for small, Slack-centric teams who need something simple and fast to set up. Its clean interface, reliable Slack bot, straightforward verification workflows, and built-in AI features make day-to-day knowledge sharing genuinely pleasant when you're under 50–70 people and your knowledge base stays relatively small. The moment you grow beyond that, though, the limitations appear quickly: per-user pricing that scales painfully, search that starts to falter, almost no customization or granular permissions, a basic editor, and the ever-present feeling that you're renting someone else's template instead of owning your company's brain. For many teams in 2025, those trade-offs stop feeling acceptable.

WikiTeq's managed MediaWiki platform (or mAItion if you want to keep your current tools and just integrate AI) removes every meaningful constraint Tettra imposes while keeping, and usually improving, the things people liked in the first place. Unlimited users with no surprise bills, complete branding and workflow freedom, search and AI that actually get better as you grow, rock-solid permissions and approvals, and the peace of mind that comes with open-source ownership and Wikipedia-level scalability. Teams that make the switch consistently say the same thing: they save money, get a system that finally feels like theirs, and watch adoption and knowledge quality soar.

Whether you select the complete MediaWiki platform for maximum control and customization or mAItion to supercharge your current stack, WikiTeq provides the most capable, scalable, and future-ready knowledge management solutions available in 2025.
