Postjam writes the caption for every scheduled post, from a fixed line, a rotating list or an AI rewrite of the text on the slide, and posts it for you.
Questions
How long can an Instagram caption be?
2,200 characters. Only the first line or two show before "more", so the first sentence does the work.
What makes a good Instagram caption?
A first line that makes the reader want the rest, a body that says one thing, and a line that says what to do: save, comment, follow. The tool writes all three.
Should I put hashtags in the caption?
A few in the caption or a block in the first comment both work. Tick "add hashtags" and the tool ends each caption with tags that fit.
Does the caption generator use AI?
Yes. What you type goes to a language model and three captions come back. Nothing is stored. Requests are limited per person so the tool stays free.
Do Instagram captions help reach?
Yes. Instagram reads the caption to decide what a post is about and who to show it to, and a caption that earns saves and comments is shown to more people.
