Your team has ideas,
your agents have capabilities,
HackMD brings them together
Teams are shipping faster than ever
AI agents handle drafts, code generation, research, and documentation. But there's a disconnect that's slowing everything down: the place where your team thinks, plans, and refines their work isn't the same place your agents can access it.
What's missing is a shared layer
Your team and your agents should always be working from the same source of truth, a place where the team sets direction, agents contribute, and everything stays aligned as ideas move from rough draft to polished output ready to ship.
That's where HackMD comes in
It's not just a collaboration tool for your team, but the shared context layer that keeps your team and your agents in sync. Your team refines ideas in one place, agents pull from that same place, and when agents contribute something back, it lands right where the team can review, edit, and build on it together.

Markdown is the layer,
humans are still in charge
HackMD is Markdown all the way down — authored, stored, versioned, and served. Humans stay in the loop, agents get clean content without a translation layer.
Works with Claude Code, Cursor, GitHub Actions, OpenAI, and any tool that speaks Markdown.
