Questions
About the caption generator
Is this Instagram caption generator free?
Yes. It is a free tool with no sign-up and no limit on how many captions you make.
Does it use AI?
No. It builds each draft from a set of caption templates in your browser, so the same topic, tone and goal always give the same five drafts. Nothing you type is sent to byline or stored.
How do I get captions that sound like me?
Connect Instagram to byline. It reads the posts you have already published, builds a profile of how you write, and makes that profile available to Claude and ChatGPT when you draft. $0.99 for your first month for eligible monthly payers, no free trial.
How many hashtags should an Instagram caption have?
This tool adds up to three, taken from the words in your topic. A few specific hashtags are easier to keep relevant than a long list; edit or remove them to suit your post.
Can I use these captions on TikTok, Threads or LinkedIn?
Yes. The drafts are plain text, so you can paste them anywhere. Check the length and hashtag habits of each platform before you post.
