Instagram caption generator: five captions, five voices.
The photo stops the scroll; the caption decides what happens next. Describe what the post shows, say what your business does and what you want from the post, and the generator writes five captions in five styles: short and punchy, a story, a question, a list, and a behind-the-scenes voice, each with a hook in the first line and hashtags on the last. Pick one, or mix the first line of one with the ending of another.

How the caption generator works
Instagram shows about 125 characters of a caption before "more", so the first line has to work alone, like a hook. The generator writes five captions that open differently and end with one next step that matches the goal you chose (a comment, a save, a message, a follow), then adds the number of hashtags you asked for, mixing broad tags with niche ones and skipping the spam tags that get posts hidden.
How to write captions that get comments, saves or messages
- One goal per post. A caption that asks for a comment, a save and a message gets none of them.
- Say the interesting thing first: the number of days, the mistake, the price of the alternative. The first 125 characters are the whole caption for most people.
- Write like you talk to a client in the shop. The behind-the-scenes style is the one that builds an audience for a small business.
- Use 5 to 10 relevant hashtags. Twenty generic ones add no reach and can read as spam; niche tags reach people who actually search them.
- End with the next step in plain words: "Send us a photo of your kitchen", not "Link in bio".
- Keep a caption bank: generate for the next five posts at once and schedule them.

Questions, answered.
Is it free?
Yes. The first run on each generator is free without any signup. After that we ask for a work email, which keeps bots from draining the generators and lets you keep your results. No newsletter.
How long should an Instagram caption be?
As long as it needs to be to make one point, with the point in the first 125 characters. Short captions work for strong images; stories and lists earn saves and time on the post.
How many hashtags should I use?
Five to ten relevant ones. Instagram allows 30, but padding with generic tags adds no reach and attracts bots. Choose the count in the form.
Does it write captions for Reels?
Yes. The same rules apply: the first line is a hook, the last line is the next step. For Reels, keep the caption shorter and put the key words on screen too.
Can it write in French, Spanish, German or Arabic?
Yes. Choose the output language in the form: English, French, Spanish, German, Arabic, Portuguese, Italian or Dutch. The generator writes natively in that language rather than translating an English draft.
What do you do with what I type?
Your inputs go to the AI model that writes the result and come back to your browser; we do not store them. If you save a report, we keep your email with the inputs and results so you can find them again, and nothing else.
Can you make the videos and images too?
We produce AI video ads and short content for brands without a shoot day. Browse the portfolio and book a free strategy call.
