How much does it cost to transcribe a batch of interviews?

Each recording costs €0.02 per minute. A 60-minute interview is €1.20; a 45-minute interview is €0.90. Multiple files can be uploaded in one session and processed concurrently. There is no per-seat licence, no subscription, and no minimum monthly spend.

How does the platform handle sensitive research data?

Audio files are automatically deleted within 24 hours of upload. They are not shared with third parties and are not used to train AI models. The platform does not retain transcripts beyond your download session. Researchers should verify compliance with their institution's IRB or ethics guidelines before uploading identifiable participant data.

Why is Gemini 3.5 Transcribe recommended for research interviews?

Gemini 3.5 Transcribe labels each speaker automatically (in-model, up to 8 speakers), which is valuable for focus groups and multi-participant interviews where attributing statements to the right speaker matters for coding. It also supports up to 1,000 entity-biasing terms — participant pseudonyms, acronyms, field-specific terms — pre-loaded before transcription, reducing the manual correction needed before coding in qualitative analysis software.

Does the output work with qualitative analysis software?

The output is plain text (.txt) that imports directly into NVivo, ATLAS.ti, MAXQDA, and other qualitative analysis tools that accept plain text files. No reformatting or conversion is needed before importing.

Recommended modelGemini 3.5 TranscribePreview

In-model speaker diarization labels each participant in a focus group or interview automatically, and entity biasing (up to 1,000 terms) covers domain terminology so names, acronyms, and field-specific terms are transcribed correctly the first time.
