Example use cases

Extract meeting notes from voice recordings
“I just finished a client call and recorded it. Can you transcribe that audio file for me? I need the full conversation converted to text so I can share it with my team and pull out the key action items.”
Turn voice memos into written documentation
“I've been recording voice memos throughout my day with ideas and notes. Can you transcribe all of them into text format? I want to compile everything into a single document I can review and organize later.”
