Tettra is a knowledge base and wiki tool built for teams that live in Slack. Its AI bot, Kai, scans your existing pages and answers employee questions directly in chat, and its content-verification workflows help keep documentation from going stale.
Key Features
Why Look for Tettra Alternatives?
Tettra's per-seat pricing adds up quickly for growing teams, and its most useful feature (the AI Slack bot) is only available on paid tiers. Teams that need more flexible content types, a genuinely free option, or a tool they already use for other work often move to broader platforms like Notion or Confluence.
Common Pain Points
- •Per-seat pricing gets expensive fast as headcount grows
- •Free plan is capped at 10 users with limited features
- •Kai, the AI answer bot, is locked behind paid plans
- •Search and organization feel shallow once the wiki grows large
- •Fewer formatting/database options compared to all-in-one tools like Notion

Tips for Switching from Tettra
Tettra alternatives: common questions
How do I export data from Tettra before canceling my account?+
Go to Settings > Export in Tettra to download all pages as Markdown or HTML files. Do this before canceling or downgrading, since export options can be limited on lower-tier plans. Note that categories, permissions, and page history won't carry over automatically, so document your structure separately.
What do I lose if I switch away from Tettra's AI bot Kai?+
You lose Kai's ability to answer employee questions directly in Slack using your wiki content, plus its content-gap suggestions. Most alternatives like Notion or Confluence don't have a built-in Slack Q&A bot, though Guru offers a comparable Slack/browser-extension answer feature. If Kai was central to your workflow, plan time to retrain the team on searching the new tool directly.
Is the free plan of Notion or Confluence enough for a 10-person team?+
Confluence's free plan supports up to 10 users with core wiki features, making it a near drop-in replacement for a small team. Notion's free plan has unlimited pages but limits page history to 7 days and caps guest collaborators, which is usually fine for internal documentation. Test with real content before fully switching to confirm the limits work for your use case.
Does the alternative integrate with Slack and Google Workspace like Tettra does?+
Yes—Confluence, Notion, and Slite all offer native Slack integrations and Google Workspace sign-in or embeds, similar to Tettra. The depth varies though: Confluence's Slack integration mostly posts notifications rather than answering questions, while Guru offers a closer match to Tettra's Q&A-in-Slack experience. Check each tool's integration page before committing.
How much will I save per year switching from Tettra to a cheaper tool?+
For a 20-person team, Tettra's paid plan (~$10/user/mo) runs about $2,400/year. Switching to Confluence's Standard plan (~$5.16/user/mo) cuts that to roughly $1,240/year, and a self-hosted BookStack setup is free aside from hosting costs (often $5-10/mo total). Actual savings depend on your headcount and which plan tier you're currently on.
