Say what the post or Reel is about, then press Generate Caption. Edit the first line before you share it.

What you get

What this generator writes, and what it leaves to you

You type a topic and, if you like, a few keywords. GPT-3.5 Turbo returns one caption with emojis and a short set of hashtags. It does not know your account, your audience or what is popular on Instagram this week, so the useful work happens in your edit: a sharper first line, a plainer keyword sentence and an ask that suits the post.

  • A first draft, fast

    One caption per click. In our test it came to about 200 characters, a sensible size for a Reel and a starting point for a longer feed post.

  • Hashtags to verify

    It usually adds three or so. Some will be real tags with an audience; others are invented and should be deleted.

  • An opening to rewrite

    Generated openings lean on stock phrases. Swap in the most specific detail you have, since that line is all most people read.

Discovery

Instagram Search Reads Your Caption

Instagram has spent the last few years telling creators the same two things: use a handful of relevant hashtags rather than a wall of them, and describe your post in plain words, because captions help people find it in search. That makes the caption less of a decoration and more of a label. A post about a three-ingredient pasta should say “three-ingredient pasta” somewhere a searcher would see it; our page on food and cooking hack videos has more topics in that vein.

The generator gets part of the way there. In our test about a short video on the 1518 dancing plague, it named the event plainly in the first line, which is good for search. It also invented a hashtag, #StrasbourgSecrets, that almost certainly has no audience, and it opened with “Unraveling the history and mystery”, a phrase that uses up the visible first line without telling anyone why to care.

Instagram has also said that shares, especially sends in direct messages, are a strong signal when it shows posts to people who do not follow you. So the best edit is often the last line: replace a generic question with a reason to send the post to someone, such as “send this to the friend who cannot stop dancing at weddings.” If you post Reels, our guide to making Instagram Reels covers the video side.

Anatomy

An Instagram caption, top to bottom

Six layers, in the order a reader meets them. Use the generated draft as raw material for each.

  1. The first line

    A reason to tap more

    Roughly 125 characters show before the fold. Spend them on the surprise or the promise, not on "Unraveling the mystery of".

  2. The keyword line

    Say what it is

    One plain sentence that names the subject the way someone would search it. Instagram search uses caption text, so this line works for discovery.

  3. The body

    Short paragraphs

    Break longer captions into two- or three-line blocks. On a phone, one dense paragraph looks like homework.

  4. The ask

    Aim for saves and sends

    "Save this for your next trip" or "send this to someone who needs it" asks for the actions Instagram weighs when it shows posts to new people.

  5. The tags

    Three to five, at the end

    Pick tags that describe the post and that real people follow. Delete any invented ones the generator adds.

  6. The alt text

    One honest sentence

    Written separately in Advanced settings. Describe what is in the image, not your marketing message.

OpenAI's GPT-3.5 Turbo. It gets your topic and optional keywords plus an instruction to add hashtags and emojis and to write for Instagram. You get one caption per click, about 200 characters in our test, which you should treat as a draft.

Instagram allows up to 2,200 characters, but in the feed it shows only the start, roughly the first 125 characters depending on the screen, before a more link. Put the reason to keep reading inside that first stretch.

Instagram's own advice to creators has been a few relevant hashtags, about three to five, rather than the maximum. The generator added three in our test. Check that each one is a real, active tag before you post.

It does not know the difference unless you tell it. Start the topic with "Reel about" or "carousel about" and say who it is for. Reels captions can be shorter, because the video and its on-screen text carry most of the message.

Not with this tool, which works from text only. Upload the picture to the image caption generator and it writes from what it sees in the image.

Yes. Before you share, open Advanced settings and write a one-sentence alt text describing the image. It makes the post usable for people who rely on screen readers and tells Instagram plainly what the picture shows.

On a paid plan, yes, to an Instagram Business or Creator account, either from the editor or on a series schedule. The AI Reels maker page explains how the videos are made and what the free plan covers.
