What is Synthesia?

Synthesia is a web-based video creation platform that uses AI avatars and text-to-speech technology to turn simple scripts into professional videos. Instead of filming yourself, you choose a digital presenter (an avatar) and let AI do the work. It’s like having a video studio in your browser—minus the stress, gear, and editing.

How Does Synthesia Work?

Synthesia takes your written script and turns it into a video by pairing it with a human-like AI avatar who speaks your words with natural-sounding voice synthesis. The platform handles the syncing, visual rendering, and delivery of a clean MP4 video.

Here’s a more thorough breakdown of how to use Synthesia:

1. Create an account: Sign up at Synthesia.io and choose your plan.
2. Start a new project: Once logged in, click “Create a new video.” You’ll see options to choose a template or start from scratch.
3. Select your presenter: Browse over 100 avatars (diverse in age, gender, ethnicity, and attire). Business plan users can even create a custom avatar.
4. Pick from over 120 languages and accents. Voices are available in various tones (professional, warm, energetic, etc.).
5. Write or paste your script: You’ll enter your text in a slide-based interface—each slide can have its own voice and avatar.
6. Customize visuals: Add images, shapes, background colors, music, or logo overlays. Drag and drop elements to build your video’s flow.
7. Generate your video: When ready, click “Generate.” Processing takes a few minutes, and you’ll receive a downloadable MP4 once complete.
8. Publish or repurpose: Use your video on YouTube, social media, product pages, emails, or internal communication.
