Markdown TTS: Read Aloud & AI Narration

Markdown TTS reads markdown, code, and docs aloud, or has AI explain them in plain language — including narrating git diffs before you commit, so you catch what changed by ear instead of skimming. Choose neural or fully offline voices. Bring your own OpenAI, Anthropic, or Groq key (Groq's free tier works out of the box) — nothing leaves your machine without it. Also includes voice input to Copilot Chat, so you can talk instead of type.
