Overview
Description

Tettra is an internal knowledge management platform built to stop teams from re-answering the same questions in Slack. It centralizes company knowledge imported from Google Docs, PDFs, and Notion, and its AI bot, Kai, searches that content to answer employee questions instantly, in-channel or via direct message.

Wiki is an open‑source, Node.js‑based wiki platform designed for developers and small teams to create, organize, and share knowledge efficiently. It runs on any web server, offering a clean UI and powerful markdown editing for collaborative documentation. Self‑hosted and free, Wiki integrates with popular tools like GitHub and Slack, enabling seamless version control and real‑time notifications. Its extensible plugin system lets you tailor the experience to fit any workflow, from project docs to internal knowledge bases.
