Quick answer
What is LUME Cortex?
LUME Cortex is LUME's short-form video editor for Macs with Apple silicon. It cuts pauses and adds captions and motion graphics on its own and, on the paid plans, schedules the video to Instagram through LUME Hub and uses AI to help you write. Every Hub account gets the free version, with a watermark and three videos a month.
Why it exists
If any of these sound familiar, the problem isn't you.
Cutting pause after pause and typing captions by hand takes longer than recording.
The video gets done in one app, the captions in another, and the scheduling in a third.
Pro editors are overkill when you just want to post this week's Reels.

AI to write your copy
On the paid plans, Cortex's AI helps you write the post caption and the on-screen text, with up to 100 requests a day.
