Best AI transcription tools for researchers
The day-one transcription stack 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?
