For agency and ghostwriter switchers

Most people pay an agency
$2,000 to $5,000+ a month for this.

Our starting plan is $97/month. Book an onboarding call and we will run one of your real recordings through SparkVox so you can compare it to what you're paying for now.

15 minutes with Sean. This is an onboarding walkthrough, not a sales pitch.

The mechanism

What $97 a month actually replaces

This isn't a template engine standing in for a junior copywriter. It starts from a real recording instead of a briefing call, and that changes what's possible.

Input length is the moat

A 30-60 minute sales or client call gives Sparky the material an agency writer would need a briefing call to extract, except you already said it out loud. A 10-second note (or a rushed brief) pulls any AI toward generic output. This is a deliberate design constraint, not a limitation.

Every post is funnel-aware

Each draft is classified Awareness, Authority, or Conversion, with hooks, length, and calls to action calibrated to that stage, so you get a content strategy over a month, not a stream of disconnected posts your agency invented from a calendar template.

The voice profile compounds, per account

Every transcript, edit, and approval feeds back into your voice model. It gets closer to you over time, instead of drifting toward the agency's house style the way a retainer eventually does.

The problem

Agency retainers don't scale with you

You're paying $2,000 to $5,000 or more a month for LinkedIn content, or you've priced it out and balked. Either way, the results are only as good as whichever account manager you got, and the math gets harder every renewal.

1

You're one of 50 to 100 clients

Agencies scale by adding accounts, not by giving your voice more attention. You get a rotation, not a relationship.

2

Turnaround runs on their schedule

Briefing calls, revision rounds, and a content calendar that moves at agency speed, not yours.

3

Voice drifts toward the house style

The longer the retainer runs, the more your posts start sounding like every other client's.

Why SparkVox

Not a discount agency. Not a prompt box either.

You might be wondering if you can skip both the agency and a new tool. Here's why that doesn't hold up for long.

Questions

What happens to my existing agency contract?+

Most people run SparkVox alongside their notice period, then cancel the retainer once they've compared a few weeks of output side by side.

How is this different from just using ChatGPT or Claude?+

ChatGPT and Claude start from zero every session. You paste a prompt, edit the output, and nothing carries forward. SparkVox transcribes a real recording, extracts the moments worth posting, drafts against a voice profile that compounds over time, and tags every post by funnel stage. It's a repeatable pipeline, not a blank prompt box.

Who has access to my recordings?+

Gladia transcribes the audio and does not retain it after transcription. Anthropic processes the transcript text via API to draft your posts. Nothing publishes to LinkedIn without your explicit approval.

Is there a free trial?+

Yes, a 14-day Pro trial. Your card is on file but you are not charged until day 15, so you can see real drafts from your own recordings before paying anything.
