How the splitter decides where to break
Nothing reads worse than a thread chopped mid-sentence. This tool splits with a hierarchy: it keeps paragraphs together when they fit, falls back to sentence boundaries when they don't, and only breaks on words as a last resort. Links on X are counted at 23 characters — exactly how X bills them — so a post full of URLs won't come up short.
Turn on numbering and each post gets a "(1/n)" suffix so readers always know where they are in the thread — the counter reserves space for it automatically.
What makes a thread actually get read
- The first post is a hook, not an intro. "A few thoughts on X" dies in the feed. Open with the most surprising claim in the piece, then let the thread back it up.
- One idea per post. If a post needs a second read to parse, split it again. White space is your friend.
- End with a handoff. The last post is prime real estate: link the full article, your newsletter, or simply ask a question that invites replies.
- Don't let pacing kill it. Publishing a 12-post thread by hand means 12 chances to get distracted. A scheduler that publishes whole threads as one linked conversation removes the fumbling.
X threads vs. Threads threads
Both platforms support linked multi-post conversations, but the rhythm differs. X gives you 280 characters per post — punchy, aphoristic, quote-friendly. Threads gives you 500 — roomier, more conversational, closer to a paragraph each. The same source text often works on both; switch the platform pill above and see which pacing suits it better.
