Best AI transcription tools for researchers
Researchers transcribe semi-structured interviews, focus groups, and noisy field recordings where accents and overlapping speech are the norm. The four below cover that range, with Rev's human-edited tier reserved for anything that will end up coded in NVivo or Atlas.ti.

Frequently asked questions
Best tool for IRB-approved interview transcription?
Rev's human-edited tier for the audio you'll cite. AI tools for prep transcription.
Can AI handle multiple speakers reliably?

How do I protect participant confidentiality?
Use enterprise tiers with data residency. Verify storage and deletion policies with your IRB.
What about local transcription?
