Synthesia

Create a training video without recording yourself.

~15 min read + 10 min hands-on

1 Why this tool matters

Synthesia turns a script into a professional-looking video with an AI presenter. For training content, onboarding videos, internal announcements, or translations, it replaces the camera, the teleprompter, the editor, and the re-shoots. You type the script; it handles the rest.

2 Walkthrough

  1. Go to synthesia.io and start a free trial.
  2. Pick an avatar that looks credible for your use case. Browse the diversity of options first.
  3. Paste a 90-second script — a welcome message, a policy explainer, a how-to.
  4. Pick a slide template. Add a few bullets on the right side of the video.
  5. Click generate. Wait a minute. Download the MP4.

3 Your turn

Today’s exercise

Record one real message you would otherwise have to shoot yourself — a welcome message, a change announcement, a tutorial snippet. Watch it. Send it if useful. Notice the uncanny-valley moments; decide whether they are a dealbreaker for your context.

4 Pro tip

Worth keeping

Synthesia shines for multilingual translation: write once, generate in 30 languages. Before you ship translated content, have a native speaker review — it is usually good, occasionally awkward.
