Synthesia

Key facts: Synthesia is an AI video platform that turns a script into a video presented by a realistic AI avatar, speaking in more than 140 languages and accents. Teams use it for training, onboarding, internal communications and product explainers that would otherwise need a camera, a studio and a presenter.

Plans: Synthesia is a paid product with a free demo and Starter, Creator and Enterprise plans; video minutes, avatars and features vary by tier. Check the official pricing page before planning a series, as minute allowances are the real cost driver.

Best for: companies that need many presenter videos in several languages, and trainers who update content often. Watch out: avatars still read as AI on close inspection, so it suits information delivery better than emotional or high-trust messaging.

Pros

• Turns a script into a presenter-led video with a realistic AI avatar — no camera, studio or presenter needed.
• Speaks in more than 140 languages and accents, making localisation far cheaper than re-shooting.
• Well suited to training, onboarding, internal communications and product explainers.
• Updating a video means editing text, not re-recording a presenter.

Watch out for

• Avatars still read as AI on close inspection, so it suits information delivery better than emotional or high-trust messaging.
• Video minutes, avatars and features vary by tier, and minute allowances are the real cost driver — plan a series carefully.
• Heavy or open-ended creative storytelling will still benefit from real footage.

Best for

Companies that need many presenter videos in several languages, and trainers who update content often. Who should skip it: anyone making emotional, high-trust or cinematic content where a real human presence matters.
