A caption can be under the hard limit and still look wrong in the feed. This preview shows where Instagram, LinkedIn, TikTok, and other networks cut your text before the "see more" link, next to the live character count for each platform.

Use it to place your hook in the visible window, then schedule the post with WriteOnce when you are ready to publish.
