Want to know more

What is Reaction to Video?

Medeo’s AI Reaction to Video tool creates reaction-style clips from text prompts. Instead of filming yourself, you can use avatars, voices, and expressions to simulate authentic reactions.

Can I use my own avatar or voice?

Yes, you can customize avatars or even upload your own voice recording to create a more personal reaction video.

Is this good for TikTok and YouTube Shorts?

Absolutely. Videos are automatically optimized for vertical and square formats, making them perfect for short-form platforms.

Do I need editing skills?

Not at all. Medeo handles the animation, syncing, captions, and exporting—no editing software required.
