Paste a long draft and get it perfectly sized for every major thread-friendly platform at once.
A free cross-platform thread splitter that takes one long draft and slices it into properly-sized posts for X (280), Threads (500), Bluesky (300), Mastodon (500), and LinkedIn — all in a single click. It's URL-aware (won't break a link mid-character), preserves @mentions and #hashtags so they stay clickable, and adds optional 1/n numbering. You can edit any post in the chain and the rest re-flows automatically. Nothing is uploaded; everything happens in the browser. No signup, no character cap on input. Built for creators and operators who want to publish the same long-form idea natively to every thread platform without rewriting it five times.
