Kettenpost

Automatically split long text into post threads for Mastodon, Bluesky, and LinkedIn

Kettenpost automatically splits long text into individual posts for Mastodon, Bluesky, or LinkedIn — including character counting that follows each platform's own rules. Paste your text, pick a platform, copy the finished posts one by one. Everything runs directly in your browser — nothing is stored or uploaded.

How it works

  1. Paste your text into the "Write your text" field.
  2. Choose a platform — the character limit is set automatically, but stays editable.
  3. Insert "===" for a manual split point.
  4. Check the preview on the right, use "Copy" to grab individual posts.
  5. Paste the posts into your app of choice.
