Speak a new language out loud with Vocal Buddy, or keep chatting in ChatGPT and Claude. English, German, French, Spanish, Portuguese, Chinese — whatever you are learning, the words you stumble on land in one notebook, defined, pronounced, and synced.
Works with the assistants you already use
Vocal Buddy exposes one MCP endpoint, so it connects to any assistant that speaks remote MCP. * Gemini CLI, the Gemini API, and Gemini Enterprise. The consumer Gemini app cannot add custom MCP connectors yet. Product names and logos are trademarks of their respective owners.

Hold a real spoken conversation in the language you are learning. The words you trip over are captured while you talk, so you never stop to take notes.
Words you discuss in ChatGPT or Claude are automatically saved via MCP protocol. No copy-paste needed.
Bidirectional sync between iPhone, Mac, and server. Your vocabulary is always up to date.
A definition in your own language and one in the word's, plus phonetics, example sentences, and the original AI conversation context.
Hear every word read aloud with system speech synthesis — including both American and British English.
Your whole notebook lives on the device. Look words up on a plane; it syncs when you are back online.
Track each word as New, Learning, or Mastered. Focus your review on what matters.
Push your word count and word of the day to a Zectrix e-ink screen. It refreshes only when something actually changes.
Real screens from a working notebook.
Both paths land in the same notebook. The server fills in definitions, phonetics, and example sentences, then syncs everything to your iPhone, your iPad, and your e-ink display.
Same account, same vocabulary — everything syncs.
