A local AI workflow workspace
built on Markdown.

MDraft helps developers and AI practitioners discover, organize, search, validate, and reuse AGENTS.md files, prompts, Cursor rules, Claude instructions, and Markdown-based AI workflows — entirely locally on macOS.

The problem

AI workflow files are spreading across your machine.

AGENTS.md files. Claude instructions. Cursor rules. Prompt specs. Research notes. Context bundles.

Most developers are managing them with Finder, VS Code tabs, scattered Markdown files, copy/paste workflows, and memory. MDraft brings those workflows into one native workspace.

Capabilities

Seven capabilities you won't find in a generic Markdown editor.

MDraft is local-first AI workflow infrastructure. The capabilities below address the actual problems of working with AI agents — discovery, validation, reuse, and assembly — not generic note-taking.

AI Context Discovery

Automatically discover AI workflow files across your Mac.

MDraft finds AGENTS.md, CLAUDE.md, GEMINI.md, SKILL.md, Cursor rules, Copilot instructions, Windsurf rules, and README files — grouped by role and kept live as you edit them elsewhere.

  • Spotlight + filesystem discovery
  • Live updates via FSEvents
  • Local-only indexing
  • Grouped by kind
  • Searchable instantly

No indexing setup. No cloud sync. No proprietary workspace. Just your files.

Prompt Library

Reusable prompts and AI instructions.

Capture prompts, reusable instructions, research briefs, evaluation specs, and AI workflows into a local prompt library. Parameterize them with variables — {{document}}, {{audience}}, {{constraints}} — then insert, copy, search, deploy, and reuse them across projects.

  • Markdown-native storage
  • Variable-aware prompts with deterministic substitution
  • Searchable across title, description, tags, and body
  • Local SQLite library — no cloud, no sync
  • Deploy any prompt back to the filesystem in one click

Semantic Search

Search by meaning, not just keywords.

MDraft indexes your Markdown documents locally using Apple's on-device language embeddings. Find related prompts, research notes, instructions, specs, and context documents — even when you don't remember the exact wording.

  • Fully local. No cloud indexing. No API keys.
  • Find Similar Notes from any open document
  • Selection-based similarity search
  • Persistent semantic index that survives relaunches

On-Device AI

AI assistance that runs on your Mac.

MDraft includes optional local AI tools that work without uploading anything anywhere:

  • Selection and document summarization
  • Metadata extraction (title, abstract, topics, type)
  • Token-budget-aware document compression
  • Tag generation with consistent kebab-case vocabulary
  • Instruction-file validation (see below)
Available on Macs with Apple Intelligence. The AI features run entirely on-device through Apple's Foundation Models framework — no cloud services, no external AI APIs, no document upload. On Macs without Apple Intelligence support, these features are hidden and the rest of MDraft works fully as a native Markdown and AI-workflow workspace.
Instruction File Linting

Lint and validate your AI instruction files.

MDraft validates the integrity of AGENTS.md, CLAUDE.md, SKILL.md, Cursor rules, Copilot instructions, and Windsurf rules.

Two passes in a single review:

  • Deterministic — missing required sections, unresolved {{placeholders}}, empty body, unknown file kinds. Runs on every Mac, every time.
  • AI-assisted — ambiguities, contradictions, vague outputs, missing constraints, hallucination-prone wording, suggested rewrite of the weakest section. Apple-Intelligence-gated.

Built for real-world AI-agent workflows where unclear instructions create bad outputs.

AI-assisted pass requires Apple Intelligence. The deterministic pass runs on every Mac.

Context Bundles

Export deterministic context bundles.

Merge open Markdown documents into a single structured bundle for LLM workflows. Manifest generation, deterministic ordering, explicit file boundaries, portable UTF-8 output.

Useful for:

  • Long-context prompts
  • Repo handoffs
  • Research packaging
  • AI-agent context injection
Web Import

Import web pages as clean Markdown.

Drop a URL into the Web Import panel and MDraft extracts the readable content, downloads images to a sibling assets folder, rewrites the markdown's image paths to local references, and stamps provenance frontmatter so you always know where the content came from.

  • Readability-based article extraction
  • Local image sidecar — assets travel with the document
  • Provenance frontmatter (mdraft.source.*)
  • Refresh from Source re-fetches and diffs at chunk level, preserving your edits
  • No browser extension. No headless browser.

…and a serious Markdown editor underneath

Preview, Markdown, and Split — your choice.

Underneath the workflow tooling, MDraft is a real native Markdown editor: Preview, Markdown source, and scroll- synced Split. Live table editing, syntax-highlighted code blocks, task lists, frontmatter, multiple windows, session restoration, keyboard-first navigation, round-trip-stable file I/O.

The editor is the foundation — but it's no longer the story. The workflow tooling is.

A short walkthrough is coming soon. For now, the screenshots above show the core workflow: discover AI instruction files, search your local Markdown corpus, validate instruction files, import web references, and export context bundles.

Privacy

Your documents stay on your Mac.

Semantic search and AI features run locally using Apple frameworks (Foundation Models, Natural Language) when available on your hardware. Web Import is the only network call MDraft ever makes — and you trigger it explicitly.
