What if you could transform your video content into polished, professional blog posts… without spending hours writing them yourself?

Sounds too good to be true, right?

Well, not anymore.

A couple of months ago, I worked with an AI expert to create a custom AI assistant that turns my YouTube videos into blog posts—and it has completely revolutionized the way I create content. This little digital helper now does 90% of the work it used to take me hours to finish, all in just a few minutes.

In this post, I’m going to walk you through exactly how you can build your own AI assistant (even if you're not tech-savvy), the tools you'll need, and the key things to include to make sure your AI actually writes like you. I’ll even give you the prompt I used so you can get up and running quickly.

Let’s dive in. 🚀

Why I Built an AI to Write My Blog Posts

Let’s face it—writing blog posts is a time-consuming task.

Especially when you’re trying to make them sound like you, keep them optimized for SEO, and provide real value to your audience.

I knew there had to be a better way… and I was right.

The custom AI I created doesn’t just write generic content. It writes in my voice, with my structure, my tone, and my ideas. And building it didn’t require any coding, fancy tech skills, or complicated software.

Just a few strategic steps and the right prompt. 🙌

Step 1: Create Your Custom GPT

To start, head over to ChatGPT and click “Create a GPT.”

Name Your Assistant

Give it a name like “YourName Video-to-Blog Generator” to keep things organized. You can also upload an image if you want—your face, a brand logo, or just something fun!

Skip the Description (Optional)

The description field is optional, so don’t worry about it unless you want a reminder of what your assistant does.

Step 2: Write Clear Instructions

This is the heart of your custom AI—and it’s where most people go wrong.

Think of this like training a new team member. If you just say, "Write a blog post," you’re leaving way too much up to chance. But if you give crystal-clear instructions, you're setting your AI up for success. This is your opportunity to teach it exactly how you want things done: the tone, the format, the structure, and even what to avoid. The more specific you are here, the better the results you'll get—and the less editing you'll need to do later.

You need to be super specific with your instructions. Tell the AI:

Exactly what you want it to do (e.g., turn video transcripts into blog posts)
What you don’t want it to do (e.g., don’t refer to “the video”)
How you want the post structured (title, intro, headings, conclusion)
What tone and voice it should use (warm, semi-formal, optimistic)
How long the blog post should be (e.g., 1,500–2,000 words)
Additional assets to include (titles, keywords, meta description, email snippet)
To reference uploaded blog post examples for your writing style

Your goal? Make it foolproof.

Step 3: Upload Style References

In the “Knowledge” section, upload several blog posts you’ve written that showcase your best work and signature style. I uploaded five of my favorite posts—because the AI will mimic whatever you give it. Make sure it's content you're proud of!

Pro tip: Export your Google Docs as Word documents before uploading—they’re easier to use with the GPT builder.

Step 4: Click "Create" — You're Done!

Once your instructions are set and your style references uploaded, hit “Create” in the top right corner. Voilà! Your custom AI is ready to go.

Now, let’s talk about how to use it.

Step 5: Get a Transcript of Your Video

To turn a video into a blog post, the AI needs a transcript.

Here are a few easy ways to get one:

Best free method: Use a browser extension to pull the transcript from your published YouTube video.
Before publishing? Use tools like:

An AI-generated transcript is totally fine for this purpose—no need to pay extra for human-transcribed content. Just grab the transcript and paste it into your GPT chat.

Step 6: Let the AI Work Its Magic

Paste the transcript into your custom GPT and… that’s it!

In just a few moments, your AI will start generating a fully structured blog post that sounds like you wrote it. It’s honestly kind of mind-blowing. 🤯

Step 7: Do a Little Light Editing (a.k.a. Add Your Human Touch)

Here’s the thing—AI can do 90% of the work, but you’ll still want to give it that final 10% of polish to make the blog truly yours. And honestly, this is where the magic happens.

Because as smart as AI has become, it still doesn’t fully understand the nuances of your personal experiences, brand story, or specific audience needs. That’s where YOU come in.

Why Editing Is Still Important

Accuracy check: AI can sometimes slightly misinterpret the transcript—especially if there are audio glitches, filler words, or overlapping speech. Give it a quick fact check to ensure accuracy.
Tone tuning: Even if your prompt is spot-on, occasionally the AI might miss the emotional nuance or conversational flair you’re known for. Soften a stiff sentence, add a dash of humor, or infuse a little personality where needed.
Style alignment: Does this post sound like you? Compare it to one of your favorite posts. If it doesn’t quite hit the mark, tweak the phrasing or sentence structure so it matches your natural rhythm.
Strategic optimization: Maybe you want to weave in a specific call-to-action, highlight a personal story, or link to a freebie or product. These finishing touches help tie the blog into your bigger business goals.

How to Edit (Without Overwhelming Yourself)

You’ve got two main options here:

1. Manual Editing

Just copy the blog post into your writing tool of choice (Google Docs, Notion, WordPress editor—whatever you prefer) and make your edits by hand. Tidy things up, adjust the wording, and make sure it flows well from start to finish.

This is great if you enjoy writing and want to stay hands-on.

2. Use Canvas Mode in ChatGPT

If you’re using ChatGPT Plus, you can open the generated post in Canvas Mode—this gives you the ability to highlight specific sections and give direct feedback to the AI. For example:

“Make this section more concise.”
“Add a personal story here about launching a course.”
“Reword this paragraph to sound more encouraging.”

This can save you time and allow the AI to assist with editing in a more interactive way—especially if you're not sure how to improve a section but you know it needs work.

Bonus Tips for Best Results

1. Customize the Prompt

Don’t just copy my prompt word-for-word. Adjust the length, tone, and other preferences to match YOUR brand voice. (You can grab my base prompt via the link in the original post.)

2. Test and Improve

Don’t settle for “good enough.” Keep testing and tweaking. If you notice the AI consistently making a mistake or missing the mark on tone, go back and update the instructions—or duplicate your GPT and refine the new version.

Why This Is a Game-Changer for Content Creators

If you’re a content creator—especially if you’re juggling YouTube and a blog—this tool can completely change your workflow.

Instead of trying to squeeze in time to write posts, your AI assistant can handle most of it for you, freeing you up to focus on creativity, strategy, or—let’s be honest—just getting a bit more sleep.

And the best part? It sounds like you. It reflects your unique ideas, tone, and perspective. Not some generic, robotic content that falls flat.

Your Next Step: Build It!

Ready to save yourself hours each week and streamline your content creation?

📅 Grab the prompt (linked in the original post or video) 💾 Upload your best writing samples 📆 Follow the steps to build your custom GPT

It takes just a few minutes—and once you’ve done it, you can use it over and over again.

Trust me, it’s worth every second. You’ll wonder how you ever created content without it.
