Frequently Asked Questions

Is Lucy OS1 better than a speech-to-text transcription tool?

Lucy OS1 is a different product. Transcription tools (like Google's voice typing, Dragon, or Whisper) convert speech to text. Lucy is a full AI voice conversation — you speak, it understands and responds intelligently. If you need transcription of long content for editing, a transcription tool is the right choice. If you want two-way AI conversation by voice, Lucy is built for that.
