Whisply review
An open-source local tool for batch transcription, diarization, and subtitle exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Whisply is an open-source application for transcribing, translating, annotating, and subtitling audio and video. Its local CLI and browser app, available for Windows, macOS, and Linux, make it a fit for technical solo users and small teams who want to process media without a paid plan. Batch processing covers files, folders, URLs, and lists, so it can handle more than one asset at a time. The workflow is aimed at people comfortable working with local software rather than buyers looking for a hosted captioning service.
Its feature depth centers on transcript and subtitle control. Whisply supports speaker annotation and diarization through WhisperX and pyannote, word-level timestamps, customizable subtitle segmentation, and post-correction with YAML rules. Exports include SRT, VTT, WebVTT, JSON, RTTM, TXT, and HTML, which gives users options for subtitle files as well as structured or readable output. The software uses OpenAI Whisper implementations and supports CPU, Nvidia GPU, and Apple MLX processing. This combination suits users who need speaker-aware transcripts, detailed timing, or repeatable correction rules; it is more specialized than a simple caption generator.
Whisply is open source and has a free plan, with no paid tier described. Translation is specified for English, which may be a constraint for teams needing other target languages. Its local, self-hosted approach and CLI option favor users who can manage software on their own systems, while support is through community and documentation. Choose Whisply for free batch transcription with diarization and export flexibility; look elsewhere if you need a hosted workflow or translation beyond English.
