How Synthesia.io Works

Synthesia, founded in 2017 by AI experts Lourdes Agapito, Matthias Niessner, Victor Riparbelli, and Steffen Tjerrild, aims to transform video content creation through AI. Their tool enables everyday users to create videos using digital avatars in different languages and removes the need for traditional video equipment. Real-looking AI avatars are also available, should you want to keep your face completely away from your content.

An overview of Synthesia and how it works.

What’s great is that Synthesia.io can generate realistic videos from just text. Here’s a simplified explanation of how it operates:

Input Text

You start by typing or providing a script or text that you want to turn into a video. (This text can be an explanation or a conversation.)

Avatar Selection

Once you sign up on Synthesia, you can pick from any of their diverse AI avatars — or create an AI avatar of you.

You can choose from various avatars or characters to represent the speaker in your video. These avatars can look like real people or be more stylized, depending on your preference.


Feel free to play around with the appearance and voice of the selected avatar. You can select from over 100 languages and customize your avatar to suit the purpose of your video. This allows you to make the video more unique and tailored to your needs.

Text-to-Speech Conversion

Synthesia’s AI takes your text and converts it into realistic spoken words using a text-to-speech (TTS) system. The voices are natural and expressive to suit the context of the text.

Video Generation

The platform combines the synthesized voice with animations and visuals to create a video that matches the spoken content. This includes ensuring the avatar’s voice is lip-synced and that the AI avatar has appropriate facial expressions and gestures.


After generating the video, you can edit and fine-tune it as needed. You can adjust the timing, add visuals, add a screen recording, and make other modifications to ensure the video looks and sounds right to you and aligns with your goals.


Once satisfied with the video, you can download it in MP4 format, get a link to share, or embed it on your site.
