You record great episodes. Then what?

You know your podcast is full of insights your audience on LinkedIn and Twitter never sees. But pulling quotes, rewriting for each platform, and formatting posts takes hours. Most coaches, founders, and consultants try it for two weeks and give up.

CastNova turns one episode into a week of posts — in minutes, in your voice. Not generic copy that sounds like everyone else. Posts that read like you sat down and wrote them.

“Why not just use ChatGPT?”

You could. Most people try it for two weeks and stop. Here's why.

ChatGPT

You paste transcript, write a prompt, tweak, re-prompt, format manually

CastNova

You upload once. Done.

ChatGPT

Output sounds generic — same voice as everyone else using the same prompt

CastNova

Output sounds like you — learned from your episodes and edits

ChatGPT

One post at a time, one platform at a time

CastNova

LinkedIn, Twitter, newsletter, blog — all at once

ChatGPT

Starts from zero every single time

CastNova

Gets better with every episode you process

It learns how you write

Generic output is easy. Every tool does that. CastNova is different: after a few episodes, it picks up your writing style and applies it to everything it creates. Your posts read like you wrote them — because they're built from your words, your patterns, your voice.

Your tone

Casual, professional, or somewhere in between — CastNova matches how you actually talk.

Your hooks

How you open posts: bold claim, question, story. It picks up your pattern.

Your vocabulary

The words you use, the ones you avoid, the phrases that are unmistakably yours.

Per platform

Different voice on LinkedIn than on Twitter? CastNova adapts to each.

The more episodes you process, the better it gets. Most users see a noticeable difference after 3-5 episodes.

From raw transcript to ready-to-publish

This is an actual transformation. Same words, same ideas — just reformatted for LinkedIn in the creator's voice.

Raw transcript23:41 – 25:08

...and the thing is, most people come to me and they say “I need more leads.” And I always push back on that. I say, “No, you don't need more leads. You need more trust.” Because what I've seen over and over again, right, is that the consultants who are closing deals fastest are the ones where the prospect already knows their thinking before the first call.

Like, they've been reading their LinkedIn posts, they've been listening to the podcast, they've seen the newsletter. So by the time they book a call, they're not asking “can you help me?” — they're asking “when can we start?” That's a completely different conversation. Uh, and it's all about visibility, not outreach. Like, stop cold-emailing people and start showing up in their feed with actual ideas...

“I need more leads.”

That's what most consultants tell me when they're stuck.

My answer is always the same: you don't need more leads. You need more trust.

The consultants closing deals fastest right now? Their prospects already know their thinking before the first call. They've been reading the LinkedIn posts. Listening to the podcast. Seeing the newsletter.

By the time they book a call, the question isn't “can you help me?”

It's “when can we start?”

That's the difference between outreach and visibility.

Stop cold-emailing. Start showing up in their feed with actual ideas.

Most founders think they need more leads. They don't. They need more trust. Here's what changed when I started sharing my actual thinking, not just my results 🧵

Sarah Kellner@sarahkellner2/4

I used to spend 3 hours per week writing LinkedIn posts from scratch. Then I realized: I already say all of this on my podcast. I was just letting it die after publish.

Sarah Kellner@sarahkellner3/4

The consultants and coaches growing fastest on LinkedIn right now aren't writing more. They're repurposing better. One conversation becomes a week of content.

Sarah Kellner@sarahkellner4/4

My rule now: if your best ideas are stuck inside hour-long episodes that 200 people hear, you have a distribution problem. Not a content problem.

Here's what most consultants get wrong about LinkedIn: They think they need to "create content." They don't. They need to share what they already know. Every week I have conversations with clients about pricing, positioning, and growth. The insights are already there — I was just keeping them behind closed doors. Since I started turning my podcast episodes into LinkedIn posts, three things happened: 1. Inbound leads doubled in 4 months 2. My newsletter grew from 400 to 2,100 subscribers 3. Prospects now show up to calls already trusting me The ideas were never the problem. Getting them in front of the right people was. What expertise are you sitting on that your audience never sees?

Why your best clients already trust you before the first call

This week on the podcast, I broke down something I keep seeing with consulting clients: the ones who close fastest are the ones who already know your thinking before they reach out.

The insight is simple: trust isn't built on sales calls. It's built over weeks of seeing your ideas in their LinkedIn feed, their inbox, their Twitter timeline.

“If your best ideas are stuck inside hour-long episodes that 200 people hear, you have a distribution problem. Not a content problem.”

Key takeaways:

  • Your podcast is a trust engine — if people actually see it
  • Repurposing turns one episode into a week of touchpoints
  • Inbound leads come from consistent visibility, not outreach

How Solo Consultants Are Using Podcasts to Build a LinkedIn Audience That Converts

The consultants, coaches, and founders growing fastest on LinkedIn right now have one thing in common: they don't write content from scratch. They repurpose conversations they're already having.

A single 30-minute podcast episode contains enough material for a week of LinkedIn posts, a Twitter thread, a newsletter issue, and a blog post. The ideas are already there — they just need to reach the right people...

Questions

What does "sounds like you" actually mean?

CastNova builds a style profile from your episodes and edits — your tone, vocabulary, how you open posts, emoji habits, even platform-specific differences. After 3-5 episodes, the output reads like you sat down and wrote it. Your LinkedIn followers won't be able to tell the difference.

How long does processing take?

Most episodes are fully processed in 2-5 minutes. You'll see real-time status updates as each step completes.

Can I edit the generated content?

Yes, everything is editable inline. Click edit on any content piece, make your changes, and it saves instantly. Your edits also feed back into your style profile — the more you refine, the better the next batch gets.

What platforms do you generate content for?

LinkedIn (long-form posts), Twitter/X (threads and standalone tweets), newsletters, blog posts, Instagram (caption drafts), and TikTok/YouTube Shorts clip suggestions.

What file formats do you support?

We accept .mp3, .wav, .m4a audio files and .mp4 video files. You can also paste a YouTube URL and we'll extract the audio automatically.
