Your source protected. Technically.

Every transcription generates a cryptographic certificate that proves — to an editor, to a court — that the text matches the original audio exactly.

SHA-256 hash of the original audio
A unique, unrepeatable fingerprint. If anyone modifies one second of audio, the seal breaks.
⏱
Verifiable UTC timestamp
Exact date and time in ISO 8601. Proves when the interview was processed.
