About Tettra
Tettra is a knowledge base built for teams that live in Slack. When a team member asks a question in a Slack channel, Tettra suggests the relevant internal doc automatically - before anyone has to type a reply. Over time this builds a self-service culture where new hires find answers without interrupting senior colleagues, and repetitive questions get answered by the knowledge base rather than by a person. The platform is deliberately simple: pages, categories, and a search bar. There are no complex hierarchies or nested folder structures to maintain. AI-powered suggestions identify which questions are being asked repeatedly and prompt knowledge owners to document the answers. Tettra suits companies in the 20-200 employee range that want a lightweight wiki without the overhead of a full enterprise knowledge management system. It is not built for external documentation or customer-facing help centres.
