Social platforms constantly shift their UI. If you’re not checking safe zones, you risk hiding faces, cutting off captions or text, and breaking your creative. This tool helps you:

Choose from real platform overlays: TikTok, Instagram Stories, Reels, Shorts, LinkedIn posts, Snap, and more. Our tool updates as the platforms do, so you’re never guessing what your audience will see.
Include your intended caption for an even more complete preview of how your post will look once live.

Need to show a boss, teammate, or client how a post will look? Upload, preview, export. Our mockups make collaboration fast and clear.

This tool is just one of the many ways Slate helps brands create better content. Our complete platform powers on-brand, ready-to-post social content for teams at the NFL, Amazon, Atlassian and more.

Drop in your content, anything from a Reel to a LinkedIn post.

Preview exactly how it’ll show up on Instagram, TikTok, LinkedIn, and more with native overlays and UI.

Make quick tweaks, download mockups, and share for review.
Try Slate for free and see how quickly your team can go from idea to publish.
