Thread Splitter

Thread Splitter helps turn long drafts into threaded posts while keeping breaks sentence-aware. It uses the character math each platform actually uses, including X’s weighted counting, so your thread stays within limits. You can also force a break with manual --- markers, and edit each post before copying it. The result is a practical writing tool for shaping threads without losing control over the final wording. It’s designed to make thread creation feel smoother, with cuts that avoid awkward mid-thought breaks whenever possible.
