Moss makes yours
Moss reads the hook, format and pacing, then drafts your version in your brand: a carousel, an ad or a script.

Broken down by Moss
Each save gets read for its hook, format, pacing and call to action, so you know why it works, not just that it did.
Remixed into your next post
Ask Moss to turn a save into a carousel, an ad or a video script in your brand voice, ready to schedule.
Shared with your team
Boards belong to the brand, so everyone on the team saves to and works from the same swipe file.

Yes. The extension signs in with your Mostly account and saves into your brand's Swipe Boards, so what you save is waiting for Moss in the app.
It's built for Chrome first. Chromium browsers like Arc, Brave and Edge should run it too. Firefox and Safari aren't planned yet.
Stop screenshotting. Start saving.
We're letting people in a few at a time. Ask for a spot and we'll send the install link.
