Instagram Caption Generator

Is the caption written by AI?

No. It is assembled from fixed text in the tool. One opening line is picked from four options for the chosen tone, one body sentence is picked for the niche, one closing line is picked for the call to action, and your topic is dropped into the body. The same inputs always produce the same caption.

How is the opening line chosen?

Each tone has four hooks, and the tool picks one using the number of characters in your topic divided by four, keeping the remainder. “Sunset beach photo” has 18 characters, so it picks the third casual hook, “Real talk:”. Changing the topic’s length can change the hook, and leaving the topic blank uses the placeholder “this moment”.

Where does my topic appear?

It is pasted unchanged at the start of the body line, ahead of a fixed niche sentence, so write it as a short phrase and fix capitalisation yourself. “Sunday long run” in the fitness niche produced “Sunday long run 💪 Consistency > perfection. Showing up every day is the goal.” Up to three of your longer topic words also become hashtags.

How are the hashtags picked?

Up to three topic words that are longer than three characters come first, then eight tags for the niche, then fifteen general tags, and the list is cut to 5, 15 or 30. Because the full pool holds at most 26 tags, the 30 option can return fewer than 30; the fitness run with “Sunday long run” returned 25. The general list includes tags such as #fyp and #viral, which you may want to remove.

What does the brand field do?

Only two places use it. In the food niche the body ends with “Full recipe/details at” followed by your brand, and with an empty field it says “in bio” instead. The “Follow for more” call to action uses it too, falling back to “@us”. For every other niche and call to action the brand is ignored.

What happens when I turn emojis off?

Every emoji is removed from the hook, body and call to action, and the leftover spacing is kept as written. The caption still ends with a divider line and a “Caption by Utinzo” credit that you should delete before posting. The three dot lines before the hashtags are part of the output, and they separate the caption from the tags.

Does it check length or tone fit?

No. It does not count characters, does not shorten anything and cannot judge whether the sentence suits your account. Read the result aloud, replace the generic niche sentence with a detail from the actual post, and check the length in the app.
