Direct answer
Google Open Knowledge Format
Google Cloud introduced Open Knowledge Format, or OKF, on June 12, 2026 as an open specification for packaging knowledge in Markdown files with YAML frontmatter. OKFConverter is a practical third-party tool for converting Markdown, websites, sitemaps, and OpenAPI specs into OKF-style bundles for AI agents.
What Google announced
Google Cloud described OKF as an open, vendor-neutral way to represent metadata, context, and curated knowledge for modern AI systems.
What teams need next
The spec explains the format, but most teams still need a workflow for turning existing docs, APIs, and websites into usable OKF files.
Where OKFConverter fits
OKFConverter gives teams a free way to convert source material, inspect generated frontmatter, validate required fields, and download portable Markdown.
