AI Reaction Video Generator

It's simple! First, write a prompt describing the event you want the AI to react to (e.g., 'React to the final play of the game'). Next, choose your B-roll media style and AI voice. Then, click 'Generate Video.' Our AI will create a complete reaction video with a split-screen layout, an AI commentator, and dynamic text, ready for you to edit and share in minutes.

The possibilities are endless! You can use our reaction video maker for almost anything. Popular uses include reacting to epic sports moments (#ufc, #nba), the latest tech news (#sora, #ai), viral TikTok videos, movie trailers, and any other trending event. If it's a viral moment, our AI can create a reaction to it.

Our advanced AI generates an avatar that acts as your on-screen commentator. Based on your prompt, the AI writes a script and animates the avatar with a wide range of realistic emotions—like shock, excitement, and laughter. The AI avatar's commentary is perfectly synced to the on-screen action, creating an authentic and engaging reaction.

Yes! You have control over the B-roll content. You can choose to have our AI generate a unique video clip from scratch or create dynamic, moving AI images based on your prompt. This ensures the visual content perfectly matches the reaction you want to create.

A split-screen or picture-in-picture (PiP) video is a popular format for reaction content. It displays two videos simultaneously. One part of the screen shows the original content or event (the B-roll), while our split-screen video maker places the AI avatar on the other part. This format allows viewers to see both the action and the reaction at the same time.

Generating a video with the AI Reaction Video Generator costs a base of 2 credits. The exact number of credits used depends on your chosen settings and subscription plan. Our paid tiers offer a generous monthly credit allowance, while free accounts receive starting credits to try the tool. For full details, please visit our pricing page.

For the best results, be specific in your prompt. Instead of 'react to a cat video,' try 'react with shock and laughter to a cat failing a jump.' Our AI uses your prompt to guide the avatar's emotions, commentary, and the dynamic captions that appear on screen. A detailed prompt leads to a more authentic and viral-worthy reaction video.

Thanks to our powerful AI, most reaction videos are generated in just a few minutes. The complexity of your prompt can slightly affect the time, but you can expect a fast turnaround. We'll send you an email notification the moment your video is ready to be edited or downloaded.

Absolutely! Every video created with Revid AI is fully editable. After generation, you can use our intuitive video editor to trim clips, adjust or add captions, change the background music, and make any other refinements to perfect your reaction video before sharing it with the world.

Our AI Reaction Video Generator creates videos in a 9:16 vertical format, which is perfectly optimized for short-form video platforms. We highly recommend sharing your creations on TikTok, YouTube Shorts, and Instagram Reels to maximize reach and capitalize on current trends.
