PandaWiki is an open-source system for building knowledge bases, powered by large language models. It helps teams quickly set up product documentation, technical documentation, FAQs and blog sites, and uses AI to assist with writing, answering questions and searching the content.

The editor supports Markdown and HTML and can export to Word, PDF and Markdown. Sites can be embedded in other websites as a widget or turned into chatbots for DingTalk, Feishu and WeCom. Content can be imported from web page URLs, website sitemaps, RSS feeds and offline files. A knowledge base is a collection of documents from which PandaWiki builds a separate wiki website, and AI features need an LLM to be configured at first login.

To self-host it you need a Linux server with Docker 20.x or newer and run the installer as root. A SaaS version also exists for those who prefer not to deploy it. PandaWiki is licensed under AGPL-3.0, so modifications and network services built on it must also be open source, and the project documentation is mainly written in Chinese.

Gramax is a free, open-source application for creating, editing and publishing documentation as code. It stores all data locally in Markdown, so it works offline and files can be edited in any text editor, and it integrates with Git for version control and collaboration. It targets product documentation portals, internal knowledge bases, project documentation and personal notes.

A visual editor makes Markdown editing easier for technical and non-technical users. The app runs on Windows, macOS and Linux as a desktop app and as a web version. Editing features include tabs, tables, video embeds, code blocks, diagrams from Mermaid, Excalidraw and Diagrams.net, and Swagger API descriptions. Git repositories on GitHub, GitLab, Bitbucket, Gitea and others can be connected, catalogs can be published to a customizable documentation portal, documentation can be written in 17 languages, and content can be imported from Confluence and Notion.

Gramax is positioned as an alternative to GitBook, Mintlify and typical static site generators. It is written in TypeScript and Rust with Tauri, and licensed under GPL-3.0.
