OpenKnowledge is an open-source, local-first markdown editor and "LLM wiki" built by Inkeep, the company known for AI search and support assistants for documentation. It reads as an AI-native alternative to Notion and Obsidian: your notes live as plain markdown files on your own machine, but you edit them in a full WYSIWYG surface that feels closer to a Google Doc or a Notion page than to a raw text file.
The hook is collaborative AI editing. OpenKnowledge connects to the Claude, Codex, and Cursor desktop apps so an AI can read, write, and restructure pages alongside you instead of living in a separate chat window. It ships with built-in MCP (Model Context Protocol) support, plus skills and templates aimed at three jobs Inkeep calls out by name: LLM wikis, "agent second brains," and spec-driven development. No-code team sharing is handled with GitHub and git under the hood, so a knowledge base is versioned and shareable without anyone touching the command line.
The project is released under the GPL-3.0-or-later license and is free to use. It ships as a native macOS desktop app, with a CLI and built-in terminal UI (TUI) that let you run it as a local web app on other systems where a packaged desktop build isn't available. It is built in TypeScript and moves fast — it's an early-stage, pre-1.0 project shipping frequent releases — so treat any specific feature, platform, or integration detail as a snapshot of an actively changing product rather than a fixed spec.
One thing to be clear about: OpenKnowledge is a place to write and organize knowledge with AI help. It is not a content generator that renders video or images, and it is not a social publisher. It produces well-structured markdown documents — the raw material for content, not the finished posts.
OpenKnowledge is where the thinking happens — the place a creator or team drafts the brief, the outline, the talking points, and the source notes for a piece of content, with an AI editing alongside them. What it deliberately does not do is turn that document into anything you can post. There's no renderer, no caption engine, no scheduler. A finished page in OpenKnowledge is a clean markdown file, and a markdown file is not a TikTok, a carousel, a newsletter, or a Reel.
That's the exact handoff Kompozy is built for. Paste the topic, outline, or transcript you wrote in OpenKnowledge into Kompozy and it generates the finished formats your notes were always meant to become: a blog article and an email newsletter from the long-form draft, a talking-head persona video and clipped shorts from the script, branded carousels and quote graphics from the key points, and platform-native text posts in your own voice through your Persona Brief. One OpenKnowledge document can fan out into 25–35 on-brand pieces across video, image, text, blog, and newsletter, then Kompozy schedules and publishes them across all nine supported platforms — TikTok, Reels, YouTube Shorts, X, LinkedIn, and the rest — from a single queue. OpenKnowledge organizes the knowledge; Kompozy produces and ships the content that knowledge becomes.
OpenKnowledge is an open-source, local-first markdown editor and LLM wiki built by Inkeep. It offers WYSIWYG editing over plain markdown files stored on your machine, with collaborative AI editing through the Claude, Codex, and Cursor desktop apps, built-in MCP support, and git/GitHub-powered team sharing.
Yes — it functions as an AI-native alternative to both. Like Obsidian it is local-first and markdown-based with files you own; like Notion it offers a polished WYSIWYG editing experience. Its differentiator is built-in AI collaboration via Claude, Codex, and Cursor and out-of-the-box MCP, skills, and templates.
Yes. OpenKnowledge is released under the GPL-3.0-or-later license and is free to use. It ships as a macOS desktop app, with a CLI and terminal UI for running it as a local web app on other systems. Because it is an early, pre-1.0 project shipping frequently, check the repository for current platform support.
No. OpenKnowledge writes and organizes markdown documents with AI help — it does not generate video or images or publish to social platforms. To turn an OpenKnowledge draft into finished posts, bring it into Kompozy, which generates video, carousels, blogs, and newsletters in your voice and publishes them across nine platforms.
Draft the outline or long-form piece in OpenKnowledge, then paste the topic or text into Kompozy. Kompozy generates the formats — blog, newsletter, carousel, persona video, short clips, text posts — in your brand voice, then schedules and publishes them across TikTok, Reels, Shorts, X, LinkedIn, and more from one queue.
