Step-by-step guide

Requirements

• A webinar transcript.
• A ChatGPT account (a free account will work).
• (Alternative) A Contrast account (you can sign up on this page).

1. Set Up Your ChatGPT Project

• Open ChatGPT.
• In the left menu, locate and click on Projects, then click on New Project.
• Give your project a name, such as "Webinar Repurposing", and click Create Project.
• Click on the name of your newly created project (e.g., "Webinar Repurposing") to add project instructions.
• Drop your prepared instructions into the project.
• Click Save to apply your project instructions. ChatGPT will now follow these instructions every time you work within this project.

2. Generate a Blog Article

• Click on the Add button within your project.
• Click on Add Photos and Files, select your webinar transcript file, and click Open.
• Use this prompt to turn the webinar transcript into a blog article:
• Click Enter to have ChatGPT generate the blog article.
• Read through the generated article. Do some quick edits to ensure the newsletter sounds like you.
• Copy the edited article into your blog, add the webinar video embed at the top, and publish.

3. Generate a Newsletter

• The newsletter will be generated using the same webinar transcript already in your project.
• Paste your prepared prompt to generate a newsletter:
• Click Enter to have ChatGPT generate the newsletter content.
• Perform quick edits to ensure the newsletter sounds like you.
• Paste the edited content into your newsletter platform (e.g., Substack) and send it to your subscribers.

4. Generate Social Media Posts

• The social media posts will be generated from the same webinar transcript.
• Paste your prepared prompt for social media posts:
• Click Enter to have ChatGPT generate the social media posts.
• Make small edits to ensure the posts sound like you and adjust any generic phrasing.
• Schedule the posts throughout the week.

(Alternative) Repurpose Your Webinar in Contrast

• Sign up to Contrast and either host your webinar directly on the platform or upload a recording.
• From the left menu, go to Videos.
• Click on the video you want to repurpose.
• On the right side you'll see the Repurpose AI section.
• Click on the format you want to create (e.g, Blog Article). Contrast will generate the content directly within the platform using your webinar content.
• Review the final content, export or copy it to your publishing platform of choice, and you're done.

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. 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.
