Transcribd

Audio in, a speaker-labeled transcript out, with every line attributed to who said it. The audio never leaves your machine.

what it does

Who said what, without the cloud

Drop in an interview or a meeting recording and Transcribd separates the voices and transcribes them, locally.

Speaker diarization

It separates voices and attributes every line to who said it, so a single mono recording becomes a clean, labeled transcript instead of an undifferentiated wall of text.

100% on-device

Transcription and diarization run on your Mac. No cloud processing, no audio upload, no per-minute rates. The recording stays where it was made.

Set the speaker count

Tell it how many people are in the room and it won't hand you five speakers for a two-person interview. Tuned for the messy reality of in-person recordings.

Built for interviews & meetings

For research interviews, meetings, and any conversation you need on the record, attributed and searchable, without sending it to someone else's server.

why it exists

Made by a researcher tired of paying to transcribe his own interviews

Remote research tools transcribe cleanly when each participant is a separate audio line. In-person interviews leave a single mono recording that is miserable to transcribe by hand, and the cloud services charge per minute to do it for you, on their servers.

Transcribd does it on-device instead: the audio stays local, and you stop paying by the minute to transcribe your own conversations.

Same privacy principle as the rest of the studio. The audio never leaves the machine.
