Chat with AI,
Build Daily Vocabulary

Speak English out loud with Vocal Buddy, or keep chatting in ChatGPT and Claude. Either way, 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.

Core Features

🎙️

Voice Conversations

Hold a real spoken conversation in English. The words you trip over are captured while you talk, so you never stop to take notes.

🤖

MCP Auto-Capture

Words you discuss in ChatGPT or Claude are automatically saved via MCP protocol. No copy-paste needed.

🔄

Cloud Sync

Bidirectional sync between iPhone, Mac, and server. Your vocabulary is always up to date.

📖

Rich Word Cards

Chinese & English definitions, phonetics, example sentences, and the original AI conversation context.

🔊

Pronunciation

Hear words in both American and British English using system speech synthesis.

📱

Works Offline

Your whole notebook lives on the device. Look words up on a plane; it syncs when you are back online.

🏷️

Learning Status

Track each word as New, Learning, or Mastered. Focus your review on what matters.

🖥️

E-Ink Desk Display

Push your word count and word of the day to a Zectrix e-ink screen. It refreshes only when something actually changes.

Two Ways In, One Notebook

Speak
  1. Open Vocal Buddy and start talking in English.
  2. Hit a word you don't have yet — it gets caught mid-sentence, without interrupting you.
  3. When the call ends, choose which of the caught words to keep.
Chat
  1. Keep using ChatGPT, Claude, or 豆包 exactly as you do now.
  2. Ask the assistant to record a word; MCP sends it straight to your server.
  3. It shows up in the notebook already looked up.

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.
