Underlord is your AI co-editor built right into Descript—a powerful creative partner that helps shape, refine, and create polished video quickly. We call it vibe editing: describe the outcome you want, and Underlord will make it happen.
Need to add scenes, apply layouts, assign and generate avatars, tighten pacing, or find b-roll? Or even something else? Just say (type) what you want, and Underlord handles it. Even if you don’t know exactly what you’re looking for, Underlord can help you get to the finish line.
Not sure what to expect from an AI co-editor?
Watch our VP of product, Laura, describe Underlord. Some things just make more sense when you see them in action.
To try it, go to Settings > Labs and toggle on Underlord. Then open any project and look for the Underlord icon in the right sidebar. Learn how to enable beta features in your app settings.
Unlimited use during beta
Underlord is currently in beta and we’re actively improving it based on your feedback. Until the end of July, you can use Underlord as much as you want — none of the AI tools you trigger through it will count toward your monthly limit. Note, manually applying AI tools and effects will still count toward your monthly AI usage.
We're offering unlimited access to encourage exploration. Test bold ideas, mix things up, and tell us what’s working well (or what could be better).
What you can ask Underlord to do
Check out our Underlord primer on the Descript blog for a behind-the-scenes look at how it works, when to use it, and how to get the most out of Descript’s AI-powered editing tools.
Unlike traditional AI tools, Underlord doesn’t just follow instructions—it applies reasoning and editing expertise to make your video look and sound better. You can ask Underlord to help with nearly any editing goal. See below for some examples, and check out the Weekly Updates at https://www.descript.com/underlord.

Why it'll be your favorite way to edit
Step into the director’s chair. Underlord doesn’t just follow orders—it helps you create. You bring the vision, your subject matter, and your instincts as a creative storyteller. Underlord brings the juice: the tools, speed, and creative boosts to help you make something you’re proud of.
Looking for AI action buttons?
Tools like Remove Filler Words, Shorten Word Gaps, and Edit for Clarity are now part of the AI tools panel. You can still use them manually — or ask Underlord to take care of them for you as part of a prompt. Learn more about manually applying AI tools.
