If you have an idea for a video but just can’t get past the writing stage, Captions’ Script Generator can take care of it for you. Just enter your concept into the prompt field and pick a template, tone of voice, and video length.

Once you’re happy with the results, generate custom SFX with Stability to emphasize your message.
Use digital characters for UGC ads

With Captions’ AI Ad Generator, you have access to realistic digital avatars that will read your script in professional-quality videos. Choose from a wide variety of characters and backgrounds — whichever best suits your brand. These avatars can even speak in multiple languages to expand your brand's reach. Customize these ads further by generating sound effects for scene changes and key points.
Create stand-out social media content

Frequently asked questions
What’s the Stability AI sound effects generator?
The Stability AI sound effects generator is an artificial intelligence tool that lets you easily create any noise you need for your project. All you have to do is describe the SFX you need, and Stability AI will create it for you in seconds.
How does sound effect generation work?
Using AI-generated sound effects is simple. Just type your text into the prompt field and click the “Generate” button. The more detailed, specific, and accurate your description, the better. AI will produce high-quality audio according to your instructions. If the results don’t quite meet your expectations, you can modify your prompt and try again as often as you like until you get the right sound for your project.
What types of sound effects can I generate?
With Captions and Stability audio, there’s no limit to the types of noises you can generate. If you need dogs barking, city traffic, or an intense thunderstorm, just describe it. For scene transitions, you might want a gentle chime or the sound of a cash register. With a text-to-SFX generator, any sound you can imagine can be yours in the time it takes to describe it.
What’s the maximum length of audio I can generate?
In general, you’ll want to create short sound effects clips of just a few seconds — a knock on a door, for example. If you run into length limitations with your audio, you can always create multiple tracks and layer them within your video timeline.
Do I need any audio production skills to use Stability AI with Captions?
No — you don’t need any technical audio production skills or special recording equipment to use Stability AI in Captions. All you need to do is describe a sound in a text prompt. AI generates the sound file for you, and then you can place it in your video’s editing timeline to adjust the noise.
