🦜 Poly-Glot AI — AI Code Documentation Platform

AI-powered code documentation for 12 languages — Web, VS Code, CLI, MCP, and GitHub App.

What is Poly-Glot AI?

Poly-Glot AI transforms undocumented code into professionally commented code — instantly.

• 12 programming languages — JS, TS, Python, Java, C++, C#, Go, Rust, Ruby, PHP, Swift, Kotlin
• Three comment modes — doc-comments (JSDoc/PyDoc/Javadoc…), why-comments (reasoning & intent), or both in one pass
• Bring your own API key — OpenAI, Anthropic, and Google Gemini supported; your key never leaves your machine
• Available everywhere — Web · VS Code · CLI · MCP · GitHub Copilot Chat · GitHub App

🔐 Authentication & Plans

Every surface requires a free account or higher plan:

• Web UI — sign in required before any generation
• CLI v1.9.0+ — poly-glot login required; server-side quota enforced
• VS Code Extension v1.4.40+ — device fingerprint + session token enforced
• MCP Server — POLYGLOT_SESSION_TOKEN required; Pro, Team, or Enterprise only
• GitHub App — API key required in .polyglot.yml

Old CLI versions (v1.0–v1.6) are deprecated on npm and blocked from all server endpoints.

🚀 Quick Start

Web

Go to poly-glot.ai, sign up free, paste code → get docs.

VS Code

# Install from Marketplace
code --install-extension poly-glot-ai.poly-glot

Then Cmd+Shift+/ (Mac) or Ctrl+Shift+/ (Windows/Linux) to generate comments.

CLI

npm install -g poly-glot-ai-cli
poly-glot login                          # create free account
poly-glot config --provider openai       # set your API key
poly-glot comment src/auth.js            # comment a file
poly-glot comment --dir src/ --yes       # comment entire directory

MCP (Pro+ only)

# Add POLYGLOT_SESSION_TOKEN from your poly-glot.ai account dashboard
# Then add to your MCP client config:
npx poly-glot-mcp

Environment variables (CI/CD)

POLYGLOT_API_KEY=sk-proj-...
POLYGLOT_PROVIDER=openai               # openai | anthropic | google
POLYGLOT_MODEL=gpt-4.1-mini
POLYGLOT_MODE=both                     # comment | why | both
POLYGLOT_LICENSE_TOKEN=<session-token> # Pro license token — skips login in CI

GitHub Actions

- name: Document code with Poly-Glot
  env:
    POLYGLOT_API_KEY: ${{ secrets.POLYGLOT_API_KEY }}
    POLYGLOT_PROVIDER: openai
    POLYGLOT_MODEL: gpt-4.1-mini

  run: |
    npm install -g poly-glot-ai-cli
    poly-glot comment --dir src/ --output-dir src-commented/ --yes

🔌 MCP Server (Pro+ only)

The MCP server lets Claude Desktop, Goose, Cursor, Windsurf, and any MCP-compatible client call Poly-Glot directly.

Requires: Pro, Team, or Enterprise plan + POLYGLOT_SESSION_TOKEN

{
  "mcpServers": {
    "poly-glot": {
      "command": "npx",
      "args": ["-y", "poly-glot-mcp"],
      "env": {
        "POLYGLOT_PROVIDER": "openai",
        "POLYGLOT_API_KEY": "sk-your-key-here",
        "POLYGLOT_MODEL": "gpt-4.1-mini",
        "POLYGLOT_SESSION_TOKEN": "your-session-token-from-poly-glot.ai"
      }
    }
  }
}

🔒 Privacy & Security

• Your code never touches Poly-Glot servers — all AI calls go directly from your machine to OpenAI, Anthropic, or Google
• API keys stored locally — in ~/.config/polyglot/config.json (CLI) or VS Code SecretStorage, never sent to us
• Session tokens — server-verified, 30-day TTL, stored in KV
• GitHub App — reads only changed PR files, never stores code
• Zero telemetry by default — opt in with poly-glot config --telemetry
