Turn YouTube subtitles into blog posts with ChatGPT

You can turn video content into written blog posts by converting YouTube subtitles with ChatGPT. This works well for content creators who want to repurpose their videos, educators turning lectures into study guides, or marketers maximizing reach across formats.

What you can make

• Blog posts from your own YouTube videos to reach readers who prefer text
• Written tutorials from how-to videos with step-by-step instructions
• SEO-optimized articles from interviews or talks to drive search traffic
• Study guides or summaries from educational videos

Skills and tools you need

• ChatGPT (free to start, some features need a paid plan): converts the subtitle text into structured blog content
• A YouTube video with subtitles (auto-generated or uploaded)
• A way to copy subtitle text from YouTube (manually from the transcript panel, or through the video settings)
• Basic text editing to review and adjust the output
• A blogging platform or document editor to publish the final post

How to build it

1. Open the YouTube video and access the transcript panel (usually found in the video description area or through the three-dot menu). Copy the subtitle text.
2. Paste the subtitle text into a text editor and remove timestamps if they appear. For long videos, copy the section you want to turn into a post.
3. Paste the cleaned subtitle text into ChatGPT with a prompt that describes your desired blog format, tone, and structure.
4. Review the generated blog post and ask ChatGPT to adjust sections, add examples, or change the tone if needed.
5. Copy the final version into your blogging platform, add images or screenshots from the video, format headings and lists, then publish.

Prompt to copy

Use this in step 3 to convert your subtitles:

Convert this YouTube video transcript into a [blog post/tutorial/article] for [your audience]. Structure it with an introduction, clear section headings, and a conclusion. Remove filler words and repetition. Keep the tone [professional/casual/educational]. Here is the transcript:

[paste your subtitle text here]

If the output needs improvement in step 4:

Rewrite the [introduction/section name] to be more [concise/engaging/detailed]. Add [bullet points/numbered steps/examples] to make it easier to follow.

Tips

• Long videos work better as a series of shorter posts—split the subtitles by topic and create multiple posts from one video
• Auto-generated subtitles often have errors, so read through once and fix any obvious mistakes before converting
• Ask ChatGPT to pull out key quotes or create social media snippets from the same subtitle text to promote the blog post
