ai-docify 0.1.0

A CLI tool for generating safe, NumPy/Sphinx style docstrings using AST parsing.

ai-docify 🤖

A simple, secure, and cost-aware CLI tool for generating high-quality NumPy/Sphinx style docstrings using AI.

ai-docify helps you document your Python code instantly using either cloud-based models (OpenAI) or local privacy-focused models (Ollama). It is designed to be safe (using AST parsing), transparent (pre-flight cost checks), and non-destructive.

✨ Key Features

• 💰 Cost-Aware Design: Calculates and displays the estimated input token cost via tiktoken before you spend a penny.
• 🔒 Privacy-First: Switch seamlessly between OpenAI (Cloud) and Ollama (Local) with a single flag. Keep proprietary code on your machine when needed.
• 🛡️ AST-Powered Safety: Unlike other tools that "guess" where to put text, ai-docify parses your code's Abstract Syntax Tree to surgically inject docstrings without breaking indentation or logic.
• ↩️ The "Undo" Button: Includes a strip command to safely remove all docstrings if you change your mind.
• ✌️ Dual Generation Modes: Choose between rewrite for speed/coverage, or inject for surgical precision.
• ⚡ "Lean" Architecture: Optimized prompt engineering ensures high-quality documentation without wasting tokens on conversational fluff.

🚀 Installation

Install ai-docify directly from PyPI:

pip install ai-docify

Prerequisites

• Python 3.8+
• Ollama (Optional, required only if using local models)

Setup (OpenAI Only)

If you plan to use OpenAI models, set your API key as an environment variable:

Mac/Linux:

export OPENAI_API_KEY=sk-your-api-key-here

Windows (PowerShell):

$env:OPENAI_API_KEY="sk-your-api-key-here"

(Alternatively, you can create a .env file in your project root)

📖 Usage

1. Generating Documentation

You must specify the Provider, Model, and Mode.

inject Mode (Recommended)

Best for: Surgical precision and preserving formatting. Uses AST parsing to find functions and classes, injecting docstrings exactly where they belong without touching a single line of your actual code.

ai-docify generate my_script.py --provider openai --model gpt-5-mini --mode inject

rewrite Mode

Best for: Speed and heavy refactoring. Asks the AI to rewrite the file with docs included. Good for initial drafts or undocumented legacy files.

# Using a local model (Free)
ai-docify generate my_script.py --provider ollama --model llama3 --mode rewrite

2. The Safety Check 🛡️

Before generating anything, the tool will pause and show you an exact cost estimate:

🤖 ai-docify: Checking my_script.py in INJECT mode

📊 Estimation (Input Only):
   Tokens: 350
   Est. Cost: $0.00009

Do you want to proceed? [y/n]:

3. Stripping Docstrings (Undo) ↩️

Need to start over? The strip command uses AST parsing to cleanly remove all docstrings from a file, leaving your logic intact. It saves the clean version to a stripped_scripts/ folder by default.

ai-docify strip my_script.py

4. Cleaning Output

To remove all generated files from the default ai_output/ directory:

ai-docify clean
