Step-by-Step Guide: How to Use Synthesia to Create an AI Video

Creating your first AI video with Synthesia is easier than editing an Instagram reel. Here’s how I do it:

Go to Synthesia.io and sign up with your email. You can start for free and test it within minutes.

Step 2: Choose a Template

  • Marketing intros
  • Customer FAQs

Pick one or start from scratch using the intuitive drag-and-drop .

Step 3: Add Your Script

Now type or paste your script. One paragraph per scene usually works best. Use the built-in AI Script Assistant if you’re stuck—it’s like ChatGPT but for videos.

Pro Tip: Write like you speak. The AI voices sound most natural when the script is conversational.

Step 4: Choose an AI Avatar + Language

Select your avatar (you can browse by ethnicity, gender, dress style, or profession). Great for diversity and inclusivity. Then pick a voice and language/accent. Options include:

  • English (US, UK, Australia, etc.)

  • German
  • Hindi
  • Arabic
  • …and 140+ others.

It even supports voice cloning—yes, you can have your exact voice used by the avatar.

Step 5: Customize Visuals

Add logos, icons, stock images (from their internal library), or upload your own assets. You can also import PowerPoint to convert decks into narrated videos.

Step 6: Preview and Render

Click Preview to check pacing and accuracy. Once you’re happy, hit “Generate Video”—and let the AI do the rest.

How Synthesia Saves Time (and Money)

I’ve made videos with agencies. It’s expensive, time-consuming, and exhausting.
