Most “AI scrapers” give you HTML soup.

We do one thing: turn a social post into clean Markdown an LLM can actually read — author, thread order, replies, all of it.

No selectors. No cleanup. Just paste the URL.

How to preview a social post

The AnyPost social post preview at anypost.md/free-tools/post-preview shows how a draft will look as a feed card before you publish. Type or paste your post, choose a network—X, LinkedIn, Threads, Bluesky, Instagram, Facebook, or Mastodon—and the tool renders a static mockup with an avatar, display name, handle, official brand icon, body text, and an action row. Hashtags, mentions, and links are highlighted the way the native composer styles them, and a live counter against each platform's character limit warns when a post will be truncated. Everything runs in the browser with JavaScript; nothing you type is uploaded. It is a layout approximation for judging length, hook placement, and hashtag balance, not a pixel-perfect screenshot—real cards vary by app version, theme, and device. Pair it with the free post linter, which scores the same draft for engagement and readability, and with Compose for Markdown-to-social formatting on the free-tools hub.

Questions

What does the social post preview do?

It renders a static mockup of your draft as it would appear in a feed card on X, LinkedIn, Threads, Bluesky, Instagram, Facebook, or Mastodon. You type the post, pick a platform, and see the layout, character count, and highlighted hashtags and links.

Is the preview pixel-perfect?

No — it is a layout approximation, not a screenshot of the live app. Real cards vary by app version, light or dark theme, and device. Use it to judge length, hook, and hashtag placement, not exact pixels.

Does my post get sent anywhere?

No. The preview is rendered entirely in your browser with JavaScript. Nothing you type is uploaded to AnyPost or any server.

Which platforms are supported?

X, LinkedIn, Threads, Bluesky, Instagram, Facebook, and Mastodon. Each uses that network's character limit so you can spot when a post will be truncated.

Can I check engagement quality too?

Yes. Pair this with the free post linter, which scores length, hook strength, hashtag overuse, emoji spam, ALL-CAPS, links, and call to action for the same platforms.
