Our take: Choose Seply if you need each speaker in a podcast, interview or meeting recording split into their own time-aligned WAV track, with an Advanced Overlap mode for crosstalk.
Main limitation: The free trial gives 30 credits, about 3 minutes of Standard separation, and Advanced Overlap needs a purchase and costs 6x the credits.
Who Seply fits
Choose Seply if you need each speaker in a podcast, interview or meeting recording split into their own time-aligned WAV track, with an Advanced Overlap mode for crosstalk. Based on the vendor's documentation, not on a hands-on test.

Also a good fit for

What is Seply, and how does it work?
Seply is a browser-based AI speaker separation service. Upload a podcast, interview, meeting or video (WAV, MP3, M4A, AAC, FLAC, MP4, MOV; up to 1 GB) and it detects speakers automatically or uses a count you provide, then outputs an individual, time-aligned WAV track for each voice. An Advanced Overlap mode targets crosstalk and simultaneous speech. Results can be previewed in the browser and remain privately accessible for 30 days. Pricing is credit-based with a cost estimate shown before processing: Standard separation costs 10 credits per started minute, Advanced Overlap 60 credits per minute, and speech-to-text 1 credit per 3 minutes. A one-time 30-credit free trial requires no card; monthly, annual and one-time credit packs are all priced in USD.
