• Speech-to-Text Transcription: Uses OpenAI Whisper API or compatible endpoints for accurate transcription
• Universal Text Insertion: Works with any input field, textarea, or contenteditable element on any website
• Clipboard Backup: Automatically copies transcribed text to clipboard as a fallback
• Multiple API Support: Compatible with OpenAI, Groq, LocalAI, and other Whisper-compatible APIs

Supported APIs
