AI Instagram Caption Generator

The AI Instagram Caption Generator writes captions that sound like you and work in the feed. Describe the post, choose your account type, voice and call to action, and get three different captions, each previewed exactly as the feed shows it, cut at "...more".

What makes it different

• Hooks that land. Every caption is previewed at Instagram's 125-character cut, with a check that the first line fits.
• Three approaches. A tiny story, a scroll-stopper and a conversation starter.
• Clean hashtags. At the end, no duplicates, and only as many as you choose.
• No bait. Engagement bait and tired phrases are flagged, even in your own edits.

How to write a caption

1. Describe the photo or video and the story behind it.
2. Choose your account type, call to action, voice, length, emojis and hashtags.
3. Click Write my captions, compare the feed previews and copy your favourite.

Caption tips

• Lead with the hook. A question, a surprising detail or the payoff.
• Add what the photo can't show. The backstory, the tip, the feeling.
• One call to action. Ask for one thing: a comment, a save or a click.

Frequently asked questions

How do I write a good Instagram caption?

Instagram now allows at most 5 hashtags per post, and a few specific ones work better than many generic ones. Choose 3–5 or the full 5; they're kept at the end, without duplicates, and never beyond the limit.

How many hashtags should I use on Instagram?

Instagram allows 30, but a few specific ones work better than many generic ones. Choose 3–5 or 8–12; they're kept at the end, without duplicates, and never beyond the number you chose.

What's the "...more" cut-off?

In the feed, Instagram shows roughly the first 125 characters of a caption and hides the rest behind "...more". If your hook is longer than that, people never see the point. The feed preview shows exactly where it cuts.

Why are some phrases flagged?

Engagement bait such as "like if you agree" or "comment YES" can get a post's reach limited, and phrases like "good vibes only" make a caption blend in. They're flagged in every caption and in your own edits.

Can I write captions for my business?

Yes. Choose Small business / brand, add your name, and pick a call to action like Shop / book or Link in bio. Include the real details (product, price, dates) in the description; nothing is made up.

Is it free?

Yes. Every day you get free AI runs, and each run writes three captions. Switching captions, editing, the feed preview and copying are always free, and the examples on this page don't use a run at all.
