Caption Generator

Captions written for the network you post on

One caption rarely works everywhere. Instagram shows a line or two before “more”, while X gives you a couple of sentences. Pinterest is different again: the description is written for search.

Pick a network above and the generator writes for it, from the length people expect to how many hashtags fit. Copy the version you like, then make it sound like you.

What changes from one network to the next

• Instagram: the first line decides whether anyone taps “more”. Lead with the point, break the text into short lines and use only the few hashtags that match the post.
• TikTok: the video tells the story. Use the caption for what the video can’t say, like context or a reason to watch to the end.
• X: one idea per post. Cut every word that isn’t doing work.
• Facebook: write the way you talk. A short story or a direct question gives people something to answer. Facebook doesn’t publish a post limit, so length is your call.
• LinkedIn: open with the lesson and keep paragraphs to a line or two. End with one thing the reader can use at work.
• Pinterest: write the description for search. It doesn’t show in the home feed, so plain words that say what’s in the Pin beat clever lines.

How to get a better caption

• Give it the angle, not just the topic. “Three mistakes I made pricing my first freelance job” beats “freelancing tips”.
• Fill in the audience. “First-time home buyers” gets different words than “real estate agents”.
• Ask for 3 or 5 versions, then keep the best line from each.
• Read it out loud before you post. If it doesn’t sound like you, change it.
