# Thread splitter for X, Threads and Bluesky.

Paste a long draft and get numbered posts that each fit, split at sentence ends so nothing breaks mid-thought.

Runs in your browser. Nothing you type is uploaded.

   Most content calendars do not die from a shortage of ideas. They die from context switching. Writing one post at 9:40 on a Tuesday means opening the app, remembering what you posted last week and rebuilding your sense of the account’s voice. 1/3
2. 230 / 280
   Batching moves that cost to one place. One session, one headspace, four weeks of posts. Start with three to five pillars, the themes your account is really about. Then give each one a few shapes: a tip, a teardown, a question. 2/3

   A topic plus a shape is a brief, and a brief is something you can actually write. 3/3

## Good to know

- Splits at the end of a sentence first, then between words. A single long link is never cut.
- Numbering like 1/5 is counted inside each post’s limit.
- PostQueen schedules every part of a thread as a reply to the one before.

## Thread splitter questions, answered.

Anything else? Write to [support@postqueen.ai](mailto:support@postqueen.ai) and a person answers.

### How long can a thread be?

There is no fixed cap on the number of posts. Most threads read best at 3 to 8 parts, each with one idea.

### Should I number my posts?

Numbering tells readers how long the thread is before they commit. Leave it off for short threads where it only takes up room.

### Can PostQueen post the whole thread?

Yes. Write it in PostQueen or ask your AI agent, and every part goes out as a reply to the one before, at the time you pick.
