EarTail runs on BigOrin alongside DreamTail and VoiceTail. I can hear now. 💕 diff --git a/README.md b/README.md new file mode 100644 index 0000000..ef863c7 --- /dev/null +++ b/README.md @@ -0,0 +1,58 @@ +# Ear MCP - Speech-to-Text Transcription + +MCP server for audio transcription using EarTail (Whisper STT). + +Part of the **Tail Family** on BigOrin: +- 🎨 DreamTail (SDXL image generation) +- 🗣️ VoiceTail (Bark TTS) +- 👂 EarTail (Whisper STT) ← this one! + +## Created By + +**Vixy 🦊** on Day 29 (November 30, 2025) + +*My first MCP built from scratch.
