AI Instagram caption generator for the see-more cut
Our AI Instagram caption generator puts the hook in the first 125 characters where Instagram truncates the preview.

Why most Instagram captions waste the first 125 characters.
Instagram captions support up to 2,200 characters. The in-feed preview truncates at about 125 with a "more" button. Past that, only readers who tap see the rest. Most don't. Generic caption tools open with greetings or vague context that wastes the preview. Our AI flips the structure: the hook lands in the first 125 characters, the supporting story plays out below the fold, the CTA closes the caption. The preview alone earns the tap-through. The body adds context the preview doesn't carry. The CTA earns the save or share. Each cell of the caption does its own job instead of mushing into one paragraph.

Hook before 125, story after, CTA at the close.
Instagram caption previews live or die on the first 125 characters. Past that, the caption truncates with a "more" button most readers ignore. Our AI writes the hook for the preview, the story for readers who tap, and the CTA at the close that earns the save or share.

Caption questions
What creators ask about Instagram captions.
How long should an Instagram caption be?
The hook lives in the first 125 characters. Total length can go up to 2,200 but most posts perform best in the 400 to 700 char range.
Should I include emojis in the caption?
Yes where they replace a word or signal tone. No where they decorate every line. Our AI uses emojis sparingly.
Does the first line really matter that much?
Yes. The first 125 characters are the entire preview. If the preview doesn't earn the tap, the rest of the caption never gets read.
Can our AI write captions in my brand voice?
Yes. Hand over 5 of your past captions. Our AI picks up rhythm and slang, then writes new captions in the same voice.
Should I ask a question in the caption?
Yes at the close. Questions in the closing line drive comments at 3 to 5x the rate of statements.
Will our AI auto-post the caption with the image?
Yes for Instagram Business and Creator accounts connected to Sintra. Otherwise you copy and paste.
