Show HN: Claudio – Audio Input for Claude.ai

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.
