Instagram Caption Generator

What the generator does, and what it doesn't

It writes from what you typed. Your details go to a free AI model through OpenRouter with a set of rules: use only your facts; never invent results, numbers, follower counts or testimonials; make no income claims; disclose an AI character as AI. Then the site checks every caption: it removes generic and like-for-like hashtags, keeps at most five, and drops any caption that runs over Instagram's limit, uses a number you didn't type, or lacks a disclosure it needs. A model can still get a fact wrong or sound flat, so read each caption and check it before you post. IImagined does not store what you type, but free model providers may keep prompts, so leave out anything private.

The structure it follows. The first line says what the post is and who it is for, in the words someone would search, because Feed shows only a line or two before "more" and that line decides whether anyone taps. Then a sentence or two on what the reader gets, then the detail, then one call to action or a real question that invites comments (never "tag 3 friends"), and up to five specific hashtags on the last line. The five options vary the opening angle and the length.

The limits, checked October 2026. Meta's publishing API reference caps a caption at 2,200 characters. Instagram's Help Center allows up to 5 hashtags on a post, a cap it began rolling out on December 18, 2025 (Social Media Today). Instagram also warned that tags like #reels or #explore "don't actually help your content appear in places like Explore" (BetaNews, December 19, 2025), and Meta's spam policy bans like-for-like swaps, so the generator removes both kinds.
