In our last video, we learned how to get a webinar transcript.

In this video, I'm going to show you how you can use that transcript to repurpose your webinar into blog article, newsletter, social media posts using ChatGPT.

So your webinar transcript is gonna act like a raw material for everything we're about to create.

If you already got it, let's set up ChatGPT.

By the way, you don't need a paid account for this.

You can see that I'm using the free account myself.

What we're going to do, we're going to create a new project called Webinar Repurposing.

This is going to be our dedicated workspace for turning webinars into content.

So to create a new project, open ChatGPT.

In the left menu, you can see Projects, and there is a button called New Project.

Click on it, give it a name— I'm going to call it Webinar Repurposing— and click Create Project.

So here in the projects, you need to write instructions once, and ChatGPT will follow them every time you drop in a new transcript.

So to add instructions to your project, you need to click on the name of your project, here you can see Webinar Repurposing.

I click on it and So once you have your instructions ready, just drop it under here, if you are using the instructions from this video, you'll have to customize this part.

And drop your company name, industry, target audience, brand voice, and tone, and add whatever you, you want here.

This is what makes the output sound like you instead of generic AI.

So now we are ready to go.

So click on Save.

What happens now?

Every time we work in this project, ChatGPT already knows who we are and how we write.

So we never have to repeat this process again.

So now that we have all the instructions ready, let's make some content.

And we're gonna start with a blog post.

First I'll need to drop my webinar transcript into this project.

For that, I'm clicking on the Add button, Click on Add Photos and Files.

Select your webinar transcript.

Click Open.

And now I need to give it a prompt to turn this webinar transcript into a blog article.

I already have my prompt ready.

So I'm gonna just paste it here.

I have the structure, I'm, I'm telling it to turn this webinar transcript into a 1,200 or 1,500-word blog article.

I included the structure, SEO requirements, and what not to include in my blog article.

And it's ready to go, so I click enter, And you can see that it's generating my article.

See how it's organizing all this?

Clear H2 sections, bullet points, everything that we need.

It's pulling out the specific data we mentioned, but I don't just copy and paste this.

I'm reading through and editing before publishing my blog article.

So maybe there are some paragraphs or some parts, that sound too AI-y.

Maybe there are some stats that need some context.

I'm reading through and editing all this before publishing.

I'm spending maybe 10 minutes editing this to, to make it sound like me.

Then I can copy it into my blog and add the webinar video embed at the top and publish.

Now let's do the same for the newsletter.

So it's the same transcript but totally different format.

Your newsletter subscribers, might not even know you ran a webinar, right?

So you are not sending a recap.

You are creating a standalone piece of valuable content that happens to come from your webinar.

So here is the prompt you can use.

I'm going to drop it here.

It's going to use the same transcript.

So when you are ready, click go.

Okay, you can see it's starting generating You see the difference?

This is like very tight.

It's a standalone piece of content that I can just publish without linking it to my webinar, my newsletter subscribers, they don't care that I ran a webinar last week or last month.

They care about these insights that helps them do their job better.

So again, I'm not just copy and pasting this into my newsletter.

I do some quick edits to make it sound like me, and then I paste it into Substack or whatever platform, and I send it to my newsletter subscribers.

Now last one, social media posts.

We're gonna get 5 different posts from this one transcript.

We're gonna again create this in the same project.

So I just paste paste my prompt in here and click enter.

It's generating my posts.

Look at this.

So I have 5 completely different angles from the same webinar.

Post 1 is about our main framework.

Post 2 highlights a surprising moment from the webinar, a surprising stat.

Post 3 shares a specific tactic or tip that we covered in the webinar.

Post 4 tells a story from the webinar.

Last one, post 5 addresses a common objection.

So I can schedule all this throughout the week, and each one drives people back to the blog article or to the webinar replay.

I can again make some small edits, to make sure they sound like me, adjusting anything that's, let's say, too generic.

And social media posts are done in what, like 15 minutes?

Let's say I'm including also the time that you're going to spend on editing this post.

Now let's review what we just created from one webinar transcript.

So we have a blog posts.

We have a newsletter and we have 5 social media about

Total time is about 40 minutes.

Most of that is editing and now that we have this ChatGPT project set up, next time takes half as long.

Just drop in the new transcript, use the same prompts, and done.

You have everything.

You have a blog post, you have a newsletter, and you have social media posts.

One webinar becomes weeks of repurposing.

If you want to make this even easier and spend even less time on this, you can use Contrast to run and repurpose your webinars.

I'm going to show you how easy it is.

So I come to Contrast, to my admin dashboard.

I already chose the webinar that I want to repurpose, and you can see on the right side, I have few options.

I can turn my webinar into a LinkedIn post, blog article, newsletter.

I can get the highlights.

Get the best quotes from the speakers, or I can ask AI to create anything I want.

So, to just compare what we got from ChatGPT and what we're gonna get from Contrast, I'm gonna just create a blog article.

So on the right side from Repurpose AI, I click on blog article, and you can see that Contrast started generating my brand.

You have the chat, you can use it to make it sound like you or change anything you want from the click— here you go, with just one click I turned my entire webinar into a blog Cheers!

So go play around with this and see you at the next one.

Common problems and solutions

Do I need a paid ChatGPT account?

No. The workflow described in first method works with a free ChatGPT account.

The output sounds too generic or "AI-written". What do I do?

This usually means the Project Instructions aren't customized enough. Go back and fill in your actual company name, audience description, and a few specific notes about your brand voice. The more specific, the better.

Can I use this workflow for other long-form content besides webinars?

Yes. The same ChatGPT project setup works for podcast transcripts, recorded interviews, conference talk transcripts, or any other long-form content you want to repurpose.

How do I stop it from inventing statistics that weren't actually in the webinar?

Add this line to your prompt:

Only use data, statistics, and examples that appear in the transcript. Do not add outside information or invent supporting evidence.

Then check the output anyway especially any numbers.

My webinar was 90 minutes long. The transcript is very long. Will ChatGPT handle it?

Technically, yes! Free ChatGPT (GPT-4o) has a 128,000 token context window, which is roughly 90,000-100,000 words. A 90-minute webinar transcript typically runs 13,000-18,000 words, so it almost always fits without issue. The real problem is attention quality, not hard limits: very long inputs cause the model to underweight content buried in the middle of the transcript (known as the "lost in the middle" problem). If you notice the output is missing key points from a specific section, split the transcript in two, ask it to extract insights from each half separately, then combine those summaries as your source material for content generation.
