## Definition

OpenKnowledge is an open-source, local-first WYSIWYG markdown editor that doubles as an LLM wiki — letting AI agents (Claude, Codex, Cursor) read, edit, and maintain a structured knowledge base of plain markdown files. Built by Inkeep, it bridges the gap between human-legible notes and machine-usable context.

The project launched on [GitHub](https://github.com/inkeep/open-knowledge) on June 3, 2026, and surfaced on Hacker News on June 25, 2026 — hitting 306 points and 152 comments — riding two converging forces: Andrej Karpathy's April 2026 LLM wiki pattern and Google Cloud's Open Knowledge Format (OKF v0.1) specification published June 13, 2026.

## Analogy

Think of it as Google Docs for your AI agent's long-term memory.

## Why it's emerging now

OpenKnowledge landed at the intersection of two June 2026 tailwinds: Karpathy's LLM wiki pattern going mainstream, and Google's OKF v0.1 turning markdown-based agent memory into a vendor-neutral standard. Its HN Show launch pulled 306 points in 24 hours — developer energy is clearly there, even as early adopters surfaced rough edges.
