Seply Speaker Separation
Seply is an online AI speaker separation tool that splits mixed audio and video recordings into individual, time-aligned speaker tracks. It is designed for podcasts, interviews, meetings, panels, and other multi-speaker recordings. Users upload files directly in the browser, choose automatic or manual speaker detection, and receive separate WAV tracks for each detected speaker while preserving the original timeline. The service supports a range of audio formats including WAV, MP3, M4A, AAC, FLAC, OGG, OPUS, WMA, and Speex, as well as video formats such as MP4, AVI, MOV, MKV, and WebM, with uploads up to 1 GB. Seply distinguishes speaker separation from speaker diarization: rather than only producing labels of who spoke when, it creates actual audio tracks for each speaker that can be edited, muted, enhanced, or reused independently. The workflow includes upload, AI processing, preview, and download. The platform also offers a speech-to-text tool and uses a credit-based pricing system with monthly plans or one-time credit purchases. A free trial provides 30 credits, and paid plans start at $12 per month. Use cases highlighted by Seply include podcast editing, interview and research workflows, meeting and panel review, and video/content production. The tool is positioned as a no-install, browser-based solution for creators and professionals who need editor-ready, time-aligned speaker tracks. It also emphasizes private processing and 30-day private result access.
