Long ideas, perfectly threaded.
Paste your essay, get a polished thread: smart splits at sentence boundaries, numbering, hook suggestions and per-post character counts — ready to publish.
I deleted half my essay before posting it — and engagement tripled. The difference wasn't the writing. It was the packaging. Here's how to turn long-form ideas into threads people actually finish 🧵
Rule one: never let a tool chop your sentence in half. A post that ends mid-thought reads like a glitch. ThreadSpin splits at sentence boundaries, every single time.
Rule two: the first post is 80% of the result. Open with curiosity, a contrarian take, or a number — then deliver one idea per post and let the numbering pull readers down the thread.
Splits at sentences, never mid-word
A sentence-aware engine that knows e.g., Dr. and U.S. aren't the end of a thought. Every post ends clean — no chopped words, no orphaned half-ideas.
Numbering that fits, guaranteed
Pick 2/7, 2. or 🧵 2/7 — ThreadSpin reserves the characters before packing, so adding numbers never pushes a post over the limit.
25+ proven hooks
A library of opener templates across curiosity, contrarian, listicle, story and data styles — with your topic slotted in. One click makes it post 1.
Live, instant preview
The thread re-splits on every keystroke, rendered as a connected timeline with per-post character counts. Over the limit glows red before you ever paste it.
Paragraphs stay intact
Preserve-paragraphs mode starts a fresh post at each paragraph break, so your essay's structure becomes the thread's rhythm — not collateral damage.
Copy one post or the lot
Per-post copy buttons for careful publishing, or Copy All with posts separated by blank lines — ready to paste into any scheduler.

Frequently asked questions
Does ThreadSpin post to X or LinkedIn for me?
No — and that's by design. Auto-posting tools need write access to your accounts, which platforms throttle and audiences can smell. ThreadSpin prepares a perfect thread; you copy and paste it wherever you publish, with zero risky API access to your accounts.
What about different platform lengths — X vs LinkedIn?
Pick the budget that matches where you post: 270 characters fills an X post with a little headroom, 250 is the safe default, and 230 leaves room for quote-posts and edits. LinkedIn allows much longer posts, so threads built for X paste there flawlessly too.
Will it ever cut a sentence in the middle?
Never mid-word, and almost never mid-sentence. The engine packs whole sentences into each post and understands abbreviations like e.g., Mr. and U.S. Only when a single sentence is longer than an entire post does it break at a word boundary — with a visible … continuation.
What are hooks and why do they matter?
The first post decides whether anyone reads post two. The hook library gives you 25+ field-tested opener templates — curiosity gaps, contrarian takes, listicles, stories and data leads — with the first words of your draft slotted in. Click one and it becomes post 1.
What does the free plan include?
Everything you need to try it properly: full smart splitting, threads up to 8 posts, 3 saved threads and the curiosity hook set. Pro ($5/mo) removes the length cap, gives unlimited saves and unlocks the entire hook library.
