Markdown TTS: Read Aloud & AI Narration - TTS + AI narration for code, docs, and git diffs in VS Code

by
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.

Hey PH! I built Markdown TTS because I kept losing focus switching between reading code/docs and doing anything else. It does two things: straight text-to-speech (neural or offline voices) and AI narration — including reading out what changed in a git diff before you review it visually, which has caught things I'd otherwise skim past. It's free and BYOK — OpenAI, Anthropic, or Groq (Groq's free tier means zero cost to try). Would love feedback, especially on the diff-narration feature — is that something you'd actually use in review, or does reading stay faster once you're used to it?
