AI Clones: Avatar Clones vs. Thought Clones (What I'm Building and Why)

4 min read

TL;DL (Too Long; Didn't Listen)

  • There are two AI clone types: avatar (video) and thought (knowledge + reasoning)
  • A strong avatar clone depends heavily on emotional range and high-quality recording
  • Transparency matters: disclose AI-generated content, especially on YouTube

I've been talking to the LLMs about clones. There are really two kinds — and understanding the difference changes how you think about scaling yourself with AI.

I'm in the middle of deciding how to build my thought clone — but in the meantime I decided to dig into HeyGen and start with an avatar clone. Here's what I've learned so far.

Building an Avatar Clone: What Actually Matters

Building an avatar clone seems straightforward — but there are things you should plan before you hit record. Some of this came from my research with LLMs, and some from my own experience creating videos.

1. Emotional Range Matters More Than You Think

I asked Gemini what emotions I should try to evoke when recording a clone. It gave me a list — but it left out humor. That's a miss.

If you're creating a clone, you should aim to capture a full range of emotions:

Happy
Serious
Skeptical
Frustrated
Curious
Humor

If your clone never smiles or laughs, it's not going to feel like you. My plan is to tell stories that trigger different emotions — things that make me laugh, get annoyed, feel excited, or even frustrated. That's how you get closer to the "real you."

2. Don't Script It — Have a Conversation

Instead of reading a script, I'm going to:

  • Have an associate stand just behind the camera
  • Ask me questions
  • Carry on a natural conversation

That's intentional. A conversational format captures natural cadence, real reactions, and authentic phrasing — in other words, how you actually think and speak.

3. Your Equipment Directly Impacts Your Clone

This part is simple but important: the better your camera and microphone, the better your clone. If you're serious about this, use the highest-quality setup you can. For me, this is obvious given I run a studio — but even outside of that, don't cut corners here. Bad input = bad clone.

How I Plan to Use My Avatar Clone

Once I build the avatar, I'll start experimenting with:

  • YouTube Shorts
  • Social media clips
  • Possibly marketing content

I'm not trying to hide the fact that it's AI. In fact, I'm doing the opposite.

AI Transparency: My Approach (and Why It Matters)

My Transparency Plan

  • Add a watermark or visual indicator to AI-generated videos
  • Include a disclosure in the video description

In my view, if you're using AI, transparency is a best practice. But it's also practical — especially on YouTube.

YouTube Policy Alert

If you upload avatar-generated content to YouTube, you are required to use the "Altered or Synthetic Content" disclosure label.

If you don't: your content may be suppressed and monetization may be limited.

What's Next

I'll be testing HeyGen over the next few weeks and will report back on quality, ease of use, best use cases, and limitations.

The thought clone is a bigger project — it's coming next. That one is about organizing all my content, making it searchable, and training something to think like me. That's going to take more time — but it's also where the real long-term value is.

Frequently Asked Questions: AI Clones

What is an AI avatar clone?

An AI avatar clone is a digital video version of you, created using tools like HeyGen, that can generate video content using your likeness and voice. It's used for YouTube Shorts, social media clips, and marketing content without requiring you to film every video yourself.

What is an AI thought clone?

An AI thought clone is a system trained on your existing content — blogs, podcasts, presentations, and writings — so it can answer questions and generate ideas in your voice and perspective. Common tools include ChatGPT Custom GPTs, Claude Projects, Gemini Gems, NotebookLM, and Notion AI.

Which is more valuable: an avatar clone or a thought clone?

Short term, avatar clones are faster to deploy for content creation. Long term, thought clones are more powerful because they scale your thinking and expertise — not just your appearance. Both serve different purposes and can be used together.

How do you make an AI avatar clone more realistic?

Three things matter most: (1) Capture a wide emotional range — happy, serious, skeptical, curious, humorous — not just neutral expressions. (2) Record conversationally, not from a script, to capture your natural cadence and authentic phrasing. (3) Use high-quality camera and microphone equipment, since bad input produces a bad clone.

Do you need to disclose AI-generated video content on YouTube?

Yes. YouTube requires creators to use the 'Altered or Synthetic Content' disclosure label for AI-generated or avatar-based videos. Failing to disclose can result in content suppression or limited monetization. Transparency is both a best practice and a platform requirement.

What tools can you use to build an AI thought clone?

The most widely used tools for building a thought clone are: ChatGPT (Custom GPTs or Projects), Claude Projects, Gemini Gems, NotebookLM, and Notion AI. Each allows you to upload your content and create an AI system that can respond in your voice and style.

Can an AI clone actually sound like you?

Yes — but only if the training data reflects how you actually speak and think. That's why unscripted, emotionally varied, high-quality recordings matter for avatar clones, and why feeding your real content (not generic text) into a thought clone system is essential.
