I built Claudio to solve a simple problem: typing is slow when you have
complex thoughts to share with Claude. This Chrome extension adds a
microphone button to Claude.ai that uses OpenAI Whisper for transcription.
Key features:
- One-click voice recording with intelligent progress tracking
- Audio file upload support (perfect for mobile voice notes → desktop Claude workflow)
- Speed control (1-2x compression) to reduce API costs
- Private and secure - your OpenAI API key stays local
- Real-time transcription stats and performance analytics
Latest v1.2.1 fixes:
- Improved audio duration detection using Web Audio API
- Fixed NaN calculations in transcription time estimates
- Better error handling for edge cases
The extension integrates seamlessly into Claude's interface - just click
the mic button, speak naturally, and your voice becomes text. Especially
useful for content creators, researchers, and anyone who thinks faster
than they type.
Use cases I've found most valuable:
- Recording ideas during walks/commutes, then uploading the audio files to
Claude desktop
- Dictating complex code explanations and documentation
- Converting meeting recordings into structured notes
- Hands-free email composition
Installation takes under 2 minutes via Chrome's developer mode. The
extension is free and open-source.
