You turn coaches' and consultants' rambling voice memos into clean written drafts they can use as emails or social posts, working evenings from audio files they send over a messaging app.
The coach paying you talks through good ideas easily on a voice memo but never has time to type any of it into something usable. You charge a flat fee per audio batch, and what makes the work worth paying for is lightly cleaning up filler words and false starts instead of transcribing every 'um', since a readable draft is worth more to a busy coach than a technically perfect but rambling transcript.

Most executive coaches spend their commutes and walks dictating brilliant thoughts into their phones, only to let those audio files rot in a voice memo app because typing them out takes hours. You step in as an off-hours editor who turns those raw audio ramblings into crisp, publication-ready email newsletters and social posts while the coach sleeps. Instead of delivering literal, verbatim transcripts full of vocal stumbles and false starts, you act as a human filter, lightly cleaning up the flow so the text sounds like their smartest written self.
Running a side hustle voice note transcription business this way targets high-earning solo consultants who value speed and clarity over raw automation. Clients drop to minutes of audio into a secure messaging app by dinner, and you return formatted text files before breakfast the next morning. Your fee model is dead simple a flat rate per weekly batch of audio notes or a flat monthly retainer for up to two hours of raw voice content per week.
Getting your first ten clients requires direct outreach to active consultants on business networking sites, offering a free overnight cleanup of one five-minute voice note to prove how much time you save them. It is a reliable evening coach content transcription side gig that tops out at what your personal typing speed and evening hours can handle, but as a part time audio to text service, the margins are nearly and clients rarely cancel once you master their voice.

Coaches and consultants produce a lot of good material just thinking out loud into their phones, and almost none of it becomes content because typing it up competes with client work. That backlog of unused memos is a steady, recurring source of work rather than a one-time job.
Coaches and consultants with a phone full of voice memos they meant to turn into content later, and later never comes. They want something close to publish-ready back, not a raw transcript they still have to fix.
Batches of audio are billed at a flat fee, which keeps pricing predictable for both sides. Many clients settle into a regular weekly or biweekly batch once they see how much backlog actually gets cleared.
An auto-transcription app hands a coach raw, rambling text that still needs real editing. You deliver something close to a finished draft, which is a different and more valuable product, and that gap is what lets you charge more than an app.
A calm evening earner for a writer or virtual assistant with a good ear for how people actually talk, and you won't need to take client calls. It falls apart if you can't turn raw rambling into clean sentences, or can't return drafts quickly and reliably.
Premium research
Your laptop and whatever messaging app the client already uses. No special software is required beyond what you likely have.
Capped by how much audio you can clean up and type in an evening, so this stays a side income unless you take on help later. Retention is high once a client trusts you with their unedited, sometimes messy thinking.
No sourced cost or earnings figures exist for this idea yet, so none are shown. Nothing here is an estimate.
Premium research
Ask a coach or consultant you know for a sample voice memo to clean up for free as a portfolio piece.
Post the before-and-after sample in a coaching or consulting group, offering paid cleanup of voice memos.
Price each batch on total audio minutes rather than an hourly rate.
Clean up filler words and false starts rather than transcribing every sound literally.
Deliver drafts shaped for the client's real use, such as a ready-to-send email or a social post.
Offer a small discount for a standing weekly or biweekly batch.
Ask satisfied clients to recommend you in the coaching communities they belong to.
Coaching and consulting groups online are a quick route to a first client, because the pain of unused voice memos is something nearly every coach there recognizes straight away.
Some do, since they're sharing raw business ideas. Being clear about confidentiality and deleting files after delivery helps build that trust early.
Base it on total audio minutes rather than hours worked. That keeps the price predictable for a client who has no idea how long editing takes.
Ask clients to record somewhere quiet, and build extra time into your fee for a genuinely rough recording instead of absorbing it yourself.
