Some networks hold only a short post. Rather than refusing a longer caption, Ocoya splits it into a **thread** — a chain of replies that reads as one piece of writing. This happens automatically on X, Threads, Bluesky and Mastodon. ## When a post becomes a thread | Network | Fits in one post | Becomes a thread above | | ----------- | ---------------- | ---------------------- | | X (Twitter) | 280 characters | 280 | | Threads | 500 characters | 500 | | Bluesky | 300 characters | 300 | | Mastodon | 500 characters | 500 | Ocoya warns you while you're writing, before you schedule anything: > Twitter caption exceeds 280 characters and will be split into a thread That's a warning, not an error — the post will publish. ## The hard limit Threading is not unlimited. Above **5,000 characters** the post is refused outright and you'll need to shorten it. So on X there are three ranges: * **Up to 280** — one post * **280 to 5,000** — a thread * **Above 5,000** — refused ## Keeping it to one post If you want a single post rather than a thread, shorten the caption until the warning disappears. Ocoya counts characters as you type. Because you can write a different caption per channel, the usual approach is a short version for X and a longer one for Facebook or LinkedIn, in the same post. ## Networks that don't thread Every other network either accepts the full caption or refuses it. Facebook takes 5,000 characters in one post, LinkedIn 3,000, Instagram 2,200 — exceed those and the post is refused rather than split.
