Locker

About

When a website asks you to upload a file, Locker takes over the picker and gives you three ways to fill it:

From your Locker workspace. Browse folders across your workspaces, pick a 
file, and it lands in the upload exactly as if you'd selected it from your
computer. No download-then-re-upload step.

From your computer. The standard file picker is always one click away if that's what you need.

Generate one. Describe what you want with AI, type the file yourself, or sketch it on a built-in drawing canvas (powered by tldraw). The result drops straight into the upload — no save-and-re-pick.

Generation matches the file types the page accepts:
