Captions with an image idea
Three captions with hashtags and an idea for the photo or graphic that fits. Copy, take the picture, post.
What makes a good Instagram caption
The generator follows these rules. They work just as well when you write yourself.
The first line decides
Instagram shows about 125 characters before "more". Put the most important or most interesting part in the first line.
Picture and text belong together
The caption explains what the picture shows or tells the story behind it. Generic text under a strong photo wastes reach.
Short lines, plenty of space
A block of text is hard to read on a phone. Short lines and line breaks make a caption easy to read.
Targeted hashtags, not many
5 to 10 relevant hashtags from your niche and region do more than 30 generic ones.
Make it worth saving
Tips, checklists and small how-tos get saved and shared. That tells Instagram your post is useful.
Frequently asked questions
Is the Instagram caption generator really free?+
Yes. You can create a few sets of captions per day without an account. If you want to create the images, plan posts and publish to Instagram, you can try myHERALD free for 14 days.
What does the generator do with my website?+
It reads the public text of your homepage and up to two subpages once. For background facts, a short search query without your company name goes to Brave. The website content and your captions are not stored.
Does the generator create the image too?+
Here you get an image idea for each caption. In myHERALD itself, every post also gets a matching AI image that you can review and change.
Can I post the captions unchanged?+
They are drafts written by AI. Read them, add a detail only you know and check every claim before you publish.
Is this available for other platforms?+
Yes, the generator also exists for LinkedIn and Facebook. In myHERALD you can also publish to X, Threads, Bluesky and WordPress.
