Seply is an AI-powered speaker separation tool that splits podcasts, interviews, meetings, and video recordings into individual, time-aligned WAV tracks for each detected speaker. Users can upload audio or video files up to 1 GB in formats including MP3, WAV, MP4, and MKV, then preview each isolated voice before downloading. Seply supports over 30 languages and handles overlapping speech through an Advanced Overlap processing mode. The service also offers speech-to-text transcription with speaker labels, and uses a credit-based pricing system with a free trial available for new accounts.
