Social Media Post Preview

Preview before you publish

The same text looks different on every network. X shows a compact card and cuts off at 280 characters, LinkedIn hides everything past its "see more" fold, and TikTok and YouTube lead with the video instead of the words. This preview switches between all 10 networks so you can catch an awkward line break, a cut-off sentence, or an over-limit caption before it goes live, not after. Anything past a platform's limit is highlighted in red.

From preview to published

This is a taste of what Posted Once does inside the composer: as you write, a live preview updates for every connected account at once, so one draft becomes a correctly formatted post for X, Instagram, LinkedIn, Facebook, TikTok, YouTube, Bluesky, Threads, Pinterest, and Google Business Profile. You can tweak the text per network where it matters, then schedule or publish everywhere in a single click, instead of copying and pasting into ten different apps.

Common questions

Is this exactly how my post will look? It is a close, realistic mockup of each network's layout and limits. Live apps vary slightly by device.

Does it check character limits? Yes. Each network's limit is applied, and anything over it is shown in red so you can trim it.

Can I preview all platforms at once? Here you switch between them. Inside Posted Once, every connected account previews together as you type.
