Engineering, design, and technical teams that want a focused real wiki without the doc-database sprawl of Notion or the enterprise weight of Confluence. Particularly strong for teams of 50 to 500 employees that already use Slack and want a wiki that unifies search across the rest of the stack.
Teams that want a doc-database hybrid (Notion or Coda better), large enterprises with Atlassian-stack procurement requirements (Confluence better), regulated buyers needing fully self-hosted (Outline or Confluence Data Center better), or teams looking for the most aggressive AI features (Slite or Notion better).
