ImpKind Local Whisper
Transcribe voice messages for free. No API keys. No costs. Runs on your Mac.
The Problem
Voice transcription APIs cost money:
- OpenAI Whisper: $0.006/minute
- Groq: $0.001/minute
- AssemblyAI: $0.01/minute
If you transcribe a lot of Telegram voice messages, it adds up.
The Solution
This skill runs Whisper locally on your Mac. Same quality, zero cost.
- ✅ Free forever
- ✅ Private (audio never leaves your Mac)
- ✅ Fast (~1 second per message)
- ✅ Works offline
Quick Start
# Install
pip3 install -r requirements.txt

Use Case: Telegram Voice Messages
Instead of paying for OpenAI API to transcribe incoming voice messages, point OpenClaw to this local daemon. Free transcription forever.
