A lightweight web-based markdown document manager for your repository

capydocs

A lightweight, pip-installable web-based markdown document manager. Point it at any directory and manage your .md files through a clean dark-themed web UI with AI-powered text refinement.

Features

• File tree — Browse .md files in a collapsible sidebar tree view
• CodeMirror 6 editor — Syntax-highlighted markdown editing
• Full CRUD + Move — Create, read, update, delete, and rename/move markdown files
• Folder management — Create and delete folders from the sidebar (+ Folder button, hover ✕ to delete, right-click context menu)
• Drag and drop — Move files between folders by dragging in the sidebar tree
• Server-side search — Search by filename and content with context snippets
• AI text refinement — Select text and refine it with OpenAI gpt-5-mini (concise, fix grammar, translate, change tone, or custom instructions)
• MCP server — Expose document management as MCP tools for AI agents
• Keyboard shortcuts — Ctrl/Cmd+S to save
• Zero config — pip install and run, no build step or database needed

Quick Start

Prerequisites

• Python 3.10+
• (Optional) OpenAI API key for AI features

Installation & Run

# Install
pip install -e ".[ai]"

# Create a .env file with your OpenAI key (optional, for AI features)
cp .env.example .env
# Edit .env and add your OPENAI_API_KEY

# Serve a directory
capydocs --dir ./docs

# Open http://localhost:8000 in your browser

CLI Options

capydocs [OPTIONS]

Options:
  --dir TEXT      Root directory to serve (default: current directory)
  --port INTEGER  Port number (default: 8000)
  --host TEXT     Host to bind to (default: 0.0.0.0)
  --reload        Enable auto-reload for development
  --help          Show help message

Development Commands (Makefile)

make install    # pip install -e ".[dev,ai]"
make run        # Start server (port 8000)
make dev        # Start with auto-reload
make test       # Run pytest
make lint       # Run ruff check
make format     # Run ruff --fix
make build      # Build package (dist/)
make clean      # Remove build artifacts

Capy Groom (AI Features)

AI-powered document grooming uses OpenAI gpt-5-mini. Set your API key in .env:

OPENAI_API_KEY=sk-...

Usage

1. Open a file in the editor
2. Click the 🦫 Groom button (or select text first for partial refinement)
3. Choose a preset or type a custom instruction
4. Review the side-by-side before/after comparison
5. Edit the result if needed, then click Apply

Presets

Preset	Description
📦 Compact	Summarize and remove unnecessary content
🔧 Fix	Polish grammar, spelling, and awkward phrasing
🇺🇸 English	Translate to English
🇰🇷 Korean	Translate to Korean

Tech Stack

Layer	Technology
Backend	FastAPI + uvicorn
Frontend	Vanilla JS + CodeMirror 6 (pre-built bundle)
CLI	Click + python-dotenv
AI	OpenAI SDK (gpt-5-mini)
Testing	pytest + httpx
Linting	ruff (E, F, I, UP, B, SIM, RUF)

API Endpoints

Method	Path	Description
GET	/api/tree	File tree
GET	/api/files/{path}	Read file
PUT	/api/files/{path}	Update file
POST	/api/files/{path}	Create file
PATCH	/api/files/{path}	Move/rename file
DELETE	/api/files/{path}	Delete file
POST	/api/dirs/{path}	Create directory
DELETE	/api/dirs/{path}	Delete directory
GET	/api/search?q=	Search files
POST	/api/ai/refine	AI text refinement
GET	/api/ai/presets	List AI presets

Design Decisions

• No build step for frontend — CodeMirror is pre-bundled via esbuild and shipped as a static asset. No npm/webpack needed at runtime.
• File-system backed — No database. Files are read/written directly to disk. What you see in the UI is what's on disk.
• Path traversal protection — All file paths are resolved and validated against the root directory before any I/O operation.
• AI as optional — Core editing works without any API key. AI features show a clear error message when no key is configured.
• pip-installable — Single pip install gives you a CLI tool. No Docker, no config files required.
• Dark theme — Catppuccin-inspired color scheme for comfortable long-session editing.

Security

• Path traversal attacks are blocked by resolving all paths and verifying they stay within the configured root directory
• API keys are loaded from environment variables or .env files, never exposed to the frontend
• The AI refinement endpoint proxies requests through the server so client never sees the API key
