Your Mind, Your Markdown, Your Machine.
HermesMarkdown is a specialized Markdown editor designed for users who need their notes to be easily readable by AI agents. It belongs to the category of productivity tools for AI-assisted workflows, targeting developers, technical writers, and project managers who rely on tools like Claude Code or Cowork. The core value of HermesMarkdown is that it structures your plain .md files so agents can identify relevant content without scanning everything, preserving precious context window space. By generating an AGENTS.md index and scoring the readability of each file, the editor ensures that agents query notes like a database rather than brute-forcing through entire vaults. This approach eliminates the need for manual tagging or external databases, keeping everything in local Markdown files.
The concrete problem HermesMarkdown solves is the inefficiency of AI agents when dropped into a vault of unstructured notes. Without prior knowledge, agents start from scratch every time, burning through context windows as they read irrelevant files or guessing wrong and pulling incorrect data. This leads to wasted tokens, slower responses, and frustrating manual file wrangling. For users who regularly ask agents to find specific information across hundreds of notes, the overhead becomes a significant bottleneck. HermesMarkdown addresses this by providing a protocol—the three-tier index in AGENTS.md—that tells agents at a glance which files to scan, which to read, and which to load fully. This systematic filtering cuts token usage and retrieval time dramatically.
The first major feature group is the AGENTS.md index with its three-tier protocol. When a vault is opened, HermesMarkdown automatically generates an AGENTS.md file that defines how agents should approach each note. The tiers are: scan read_when to filter without loading files, read scope to confirm relevance, and load the full file only when necessary. This hierarchy ensures that an agent reads only the metadata first, making quick decisions without waste. The status bar displays a live readability score for the current file, drawn from frontmatter completeness, heading structure, typed code fences, table usage, and bold anchors. Users can see at a glance whether a file is agent-ready, without opening separate tools. This feature directly reduces token consumption and speeds up interactions.
The second major feature group is the frontmatter wizard and customizable metadata fields. HermesMarkdown comes with four default fields—scope, read_when, related, and tags—but users can drop, rename, or skip any of them entirely. A wizard walks users through these fields when creating new files, making setup painless even for non-experts. The editor also scores heading structure, typed code fences, table formatting, and bold anchors, so even a plain note without frontmatter earns a meaningful readability rating. This flexibility means that users can adopt as much or as little structure as their workflow demands. Every agent that reads the vault benefits from whatever structure is added, and the improvements are permanent. The wizard ensures consistency without forcing a rigid schema.
