thread splitter

Write it all in one place, then split it into a clean numbered thread that fits X's limit - each tweet ready to copy and post in order.

threads that actually get read

A good thread front-loads the payoff: your first tweet is the hook that earns the second. Splitting cleanly on word boundaries (not mid-sentence) keeps each tweet readable on its own, which matters because people quote and save individual tweets from a thread. Want tweet one to actually land? Score it with the hook analyzer.
