AI workflows are moving fast, and teams are switching between more LLMs than ever

The HackMD CLI helps keep context portable by letting developers create, update, and organize Markdown notes directly from the terminal

That means prompts, skills, project notes, and agent memory can stay connected in HackMD, even as your team moves between different AI tools

Less lost context
More consistent workflows

Better collaboration between humans and agents

HackMD is now System and Organization Controls (SOC) 2® Type II compliant 🔐

Here's what this means:

🔍 An independent CPA firm assessed our controls relevant to security

🔁 The Type II report covers how those controls operated over a period of time, not just a snapshot

📄 Your security team can review the full report as part of vendor due diligence

Your team's knowledge deserves more than "trust us" and now you don't have to take our word for it

AI agents work better when they have the right context in the right place

With HackMD’s Folders API, your team can organize notes, skills, workflows, and documentation into structured folders that agents can reference and act on more reliably

Instead of scattered files or disconnected knowledge, you can create a workspace where human collaboration and agent-ready context live together

Give your agents better context
Give your team better outcomes
