Rev is a transcription and investigative technology brand that helps legal teams turn digital evidence into searchable, citable findings. Its investigative intelligence platform brings case materials—including body-camera footage, interviews, jail calls, witness statements, documents, and photos—together for multi-file analysis. Users can ask questions across a case record, identify potential inconsistencies, and trace findings to their source. The platform also supports image analysis, transcript editing and clipping, repeatable investigative workflows, and drafting case documents for export to Word or PDF. A mobile app lets teams record, transcribe, and review evidence in the field.

Rev offers AI transcription as well as human-verified services, including human transcription, English and Spanish captions, legal rough drafts, premium legal transcripts, court-reporting support, and subtitles in 17 languages. Its legal services are designed to support work from initial evidence review through certified transcripts. Rev serves prosecutors, criminal defense teams, law enforcement, civil law practices, and court-reporting agencies, as well as customers in research, journalism, education, and video accessibility. It also provides a speech-to-text API for developers.
