Instagram caption generator について

A good Instagram caption does two jobs: its first line stops the scroll, and the rest gives people a reason to like, comment or save. Describe your photo, reel or carousel in a sentence or two, and the caption generator writes five different captions to choose from, each from another angle: a little story, a question, a tip, a joke, a call to action.

Choose a tone (casual, fun, inspiring, professional or witty) and a length. Short captions stay under 125 characters, roughly what shows before the “more” link; medium ones run two or three sentences; long ones tell a small story in short lines. Hashtags come separately, none, three or five per caption, so you can put them in the first comment instead if you prefer, and emoji can be switched off for a cleaner look. Each caption shows its length against Instagram's 2,200-character limit and copies together with its hashtags.

Captions are written by Claude, Anthropic's AI model, in the language of your description unless you pick another. They mention only what you told the generator, so prices, dates and places stay accurate; add them to the description if they matter.

The generator can't see your photo, so describe what's in it. It doesn't post to Instagram, schedule posts or research which hashtags are trending this week.

プライバシー

Your description of the post and your tone, length, hashtag and emoji settings are sent when you press Write captions, from this page to our server and on to Anthropic's API. The captions come back and nothing is saved or logged on our side, and Anthropic's terms keep the text out of model training. No photo is ever uploaded, because the tool only reads what you type.

Instagram caption generator:よくある質問

How many hashtags should I use on Instagram?
A few well-chosen tags tend to work better than a block of thirty, and Instagram's own creator tips have suggested three to five. That's why the generator offers none, three or five per caption. Pick tags that describe the post and your niche; very broad tags such as #love help little, because millions of posts use them every day.
Why does the first line of a caption matter so much?
In the feed, Instagram shows only the start of a caption before cutting it off with “more”, so the first words decide whether anyone reads the rest. Every caption the generator writes opens with a hook. The Short option keeps the whole caption under 125 characters, so on most phones nothing is hidden at all.
Can it write captions in Uzbek or Russian?
Yes. Write the description in the language you post in and the captions come back in that language, or choose one of sixteen languages from the menu, for example to post the same photo in English and in Uzbek. Hashtags follow the caption language, so check that the tags are ones your audience actually searches for.
Will the captions make things up about my business?
They shouldn't. The generator is told to mention only facts from your description, so it won't invent a price, a discount, an opening date or an award. If you want those in the caption, put them in the description. Read each caption before posting anyway, because AI can still guess at a detail the description left vague.
Is my description or photo sent anywhere?
No photo is involved: the tool works only from the words you type. The description goes to our server and to Anthropic's API when you press the button and isn't stored or logged by us. We count requests per connection in memory to apply the free limit of 20 a day, and that count resets after 24 hours.
