Features
Transcription in 54+ languages
Audio and video files are converted into timestamped transcripts at a stated 99% accuracy across 54+ languages, with speaker diarization marking who said what.
AI Insights and summaries
Summaries, chapters and sentiment analysis are generated from each transcript, giving short written overviews of long recordings.
Multi-transcript analysis
Questions can be asked across whole folders of transcripts and uploaded documents to surface patterns that a single recording does not show.
Tool integrations
Zoom, Teams, Zapier and Adobe Premiere connections move recordings in and edited transcripts out of the platform.
Security and redaction
SOC 2 Type II controls, AES-256 encryption and a zero-training policy on uploaded data support sensitive legal, medical and law enforcement work.
What users say
Pros
- Transcripts of overlapping phone calls came back accurate, and quiet or muffled speech was transcribed cleanly.
- Transcripts came back very quickly, including a batch of 16 videos and MP4 call recordings.
- Hourly metered billing suits one-off batches, so occasional projects need no ongoing subscription.
Cons
- Danish recordings come back with hallucinated words and other errors that need correcting.
- A 28-minute video took over two hours to upload, with the last fraction of the file stalling.
- Costs are high for light use, and the free allowance is a single 30-minute trial.
