Tettra is a lightweight internal wiki built around Slack and Microsoft Teams, with an AI-powered knowledge bot and gentle 'knowledge management' prompts that flag stale or missing docs. Teams love how little setup it needs, but it can feel too basic once you need rich pages, granular permissions, or a customer-facing help center. Its per-user pricing and Slack-first design also make it a poor fit for teams that live outside chat.
Last updated 2026-07-16 · We compared internal knowledge-base and wiki tools that overlap with Tettra's core job: capturing team answers and surfacing them fast. Each pick was assessed on editor depth, search and AI retrieval, permissions, chat integrations, and price tier.

AI answers over a clean team wiki
Slite pairs a distraction-free doc editor with 'Ask', an AI that answers questions straight from your knowledge base and cites the source. It hits a similar simplicity sweet spot to Tettra with stronger writing and organization tools. The trade-off is fewer native workflow automations, and its opinionated structure gives less freedom than a fully flexible workspace.

Guru surfaces answer 'Cards' inside Slack, Chrome, and your other tools, and its verification workflow assigns owners to keep facts current. That trust layer is more mature than Tettra's staleness nudges, making it strong for support and sales enablement. It is heavier to administer, though, and priced above simple wikis.
Best for: Support and sales teams needing verified answers
Notion turns pages, databases, and wikis into one endlessly customizable workspace, going far beyond Tettra's focused note-taking. Its AI can draft and answer across your content, and the free tier is generous for small teams. The flexibility is double-edged: without discipline, Notion workspaces sprawl and search can feel noisy.

Slab focuses on well-structured, good-looking internal documentation with topic-based organization and search that reaches into Slack, Google Drive, and more. It feels more polished for long-form knowledge than Tettra's shorter pages. It leans less on chatbot-style AI, however, and larger libraries can need careful curation to stay tidy.

Document360 is a purpose-built knowledge-base platform with versioning, workflows, analytics, and both private and customer-facing portals. It scales well past Tettra when you need a real help center or documentation product. The flip side is a steeper learning curve and higher cost that outmatch a small internal wiki's needs.
