That voicemail from your client can finally turn into notes

Think about where information goes to die in your business.

The voicemail where a client walks you through exactly what they want. The memo you talked into your phone in the truck after a site visit. The recorded consult call. It's all there, and none of it is searchable. Two weeks later you're scrolling through audio trying to find the part where they mentioned the deadline.

As of October 6, paid ChatGPT plans can take an audio file and turn it into a transcript, a summary, or answers about what was said. OpenAI's help article is clear that free accounts can't do this yet.

How to do it

First, get the recording as a file. MP3, M4A, WAV, and a handful of other common formats work. iPhone voice memos save as M4A, so those are fine. One catch: if the recording came from a video call, export just the audio. Files that come through as video aren't supported.

Second, open ChatGPT, attach the file, and tell it exactly what you want. "Summarize this" gets you a summary. A specific ask gets you something you can use. A few to steal:

This is a recording of a site visit for a kitchen remodel. List the client's requests, every measurement mentioned, anything they said they're unsure about, and draft a short follow-up email confirming what we discussed.

This is a voicemail from a client. Tell me in two sentences what they need and whether there's a deadline.

This is a recording of our team meeting. List every decision we made and every task someone agreed to do, with their name next to it.

Third, check it. OpenAI says transcripts and speaker labels can have errors. Names, numbers, and dates get checked every time, with no exceptions. If the email says the cabinets are 36 inches and the client said 30, that's on you, not the software.

Two things before you upload

Recording consent. Rules on recording conversations vary by state, so know yours. Beyond the law, just tell people. "Mind if I record this so I don't miss anything?" is an easy ask, and clients tend to take it as a sign you're paying attention.

What you're handing over. Uploading a recording means sending a client conversation to an outside company. For a site walkthrough, fine. For a privileged legal conversation, someone's medical details, or a client's finances, stop and think first. If you're on a Business or Enterprise workspace, look at your data settings before you start.

Long recordings can also time out. If you've got a two-hour meeting, split it into chunks.

Your homework: pick one voice memo or voicemail sitting on your phone right now, the one you keep meaning to deal with, and run it through this week. If it turns ten minutes of listening into thirty seconds of reading, you'll know whether it earns a place in your routine.
