Lucy Edit AI

Lucy Edit AI is a foundation model for text guided video editing, released and open sourced by DecartAI. Instead of masking, keyframing or scrubbing a timeline, you upload a video and describe the change you want in plain language. The model can swap clothing, add accessories, transform a character's image while keeping facial and body features consistent across every frame, or modify the background entirely. Processing is described as fast, with results in seconds, and the interface is built so you can start typing instructions immediately. The tool is free to use and is aimed at content creators, editing enthusiasts and commercial promoters.

- Change an outfit or add accessories with one instruction

- Transform a character while keeping features consistent

- Replace or adjust the background of a clip

- Prototype a creative idea before committing to a real edit

- Creators who need quick wardrobe or prop changes

- Editing enthusiasts trying out unusual ideas

- Promoters adjusting details in product videos

This is the kind of tool that can be misused. Editing a real person's appearance without their consent can break platform or school rules, and in many places it can break the law, so the responsibility sits squarely with you. Do not use it to impersonate anyone, to mislead viewers, or to create material that puts a real person in a false situation. Even with consent, complex instructions can produce inconsistent frames, so review the full clip rather than a single still. The model is free now, but access terms and behavior can change, and anything you publish should be checked against the rules of the platform you post on.
