The problem it solves

Standard transcription tools cut off around 20 minutes of audio, so a long meeting, interview, or podcast episode won't go through in one piece. Splitting the pieces yourself and stitching the text back together eats up an afternoon.

Who it fits

Content creators, podcasters, or businesses that record long meetings or interviews and need a full written transcript.

How it works

  1. You upload an audio file and your email through a web form
  2. The system splits the file into smaller chunks automatically
  3. Each chunk is transcribed using OpenAI's Whisper model
  4. All the transcribed chunks are merged into one document
  5. The complete transcript is emailed to you
What you get

A written transcript ready from any recording

You upload a long recording and get a complete written transcript back by email, no matter how long the audio runs.

What you get

A single, complete text transcript of your full audio recording, delivered by email.

What you need

An OpenAI API account with Whisper access and a Gmail account for delivery.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
