How to make AI captions sound like you (not like ChatGPT)

Followers can spot an AI caption in a line. Here's why they all sound alike, the specific giveaways to cut, and how to get AI writing in your voice by feeding it your own past posts.

Why AI captions all sound the same

Ask any general AI model for "an engaging Instagram caption" and it returns the average of every caption it has seen: an excited opener, a few hype verbs, an emoji bullet list and a neat moral at the end. Telling it to be "friendly" or "witty" doesn't help much, because those words describe millions of accounts. What makes your writing yours is specific: how long your sentences are, how you open, words you repeat, whether you use emoji at all, how you ask for the click.

The giveaways to cut first

These patterns are rare in posts people write themselves and very common in AI output:

  • Hype verbs: "elevate your", "unlock the", "unleash", "supercharge", "transform your", "take it to the next level".
  • Vocabulary: "delve", "tapestry", "seamless", "testament to", "game-changer", "in today's fast-paced world".
  • Em dashes scattered through a short caption.
  • "It's not X, it's Y" and "Whether you're X or Y" framing.
  • Emoji bullet lists (🚀 ✅ 💡) and a tidy moral to close.

Paste a caption into the free AI caption humanizer to see which of these it contains and get three rewrites without them.

Give the AI evidence, not adjectives

The reliable way to get your voice back is to show the model how you actually write. A method that works with any AI tool:

  1. Collect 6-10 posts you wrote yourself that did well. Skip anything AI wrote.
  2. Ask for a written description of the voice: tone, point of view, how posts open, signature phrases, emoji, hashtag and call-to-action habits, formatting. The free brand voice analyzer does this step.
  3. Turn that into 5-7 short rules ("Open with a specific number or moment", "No exclamation marks", "Sign off with a question") and paste them at the top of every prompt.
  4. Add two of your real posts as examples under the rules. Examples beat descriptions.
  5. Edit what comes back and keep the edits. If you keep fixing the same thing, it's a missing rule.

Doing it automatically

Cadenzova does this on its own. When you connect Instagram, TikTok, Pinterest, Threads, YouTube, Bluesky or X, it reads your existing posts (read-only) and builds a writing-style profile: tone, point of view, formality, hooks, signature phrases, vocabulary, emoji, hashtag and CTA habits, formatting, content pillars, what your best posts have in common, and how you write differently per platform, plus measured stats like average length. Every caption, title and hook is then written to match, with your own written instructions taking priority, and checked against the giveaway list above before you see it. You can view it, re-analyse it or switch it off in Settings → Learned writing style. Facebook Pages and LinkedIn are excluded for now because their APIs don't let apps read past posts with the current permissions.

Frequently asked questions

Can I train ChatGPT on my writing style?

Not in the sense of retraining it, but you can give it your voice in every conversation: a short list of voice rules plus two or three of your real posts as examples. Saving those to a Project or custom instructions makes it stick.

How many posts does an AI need to learn my voice?

Three is the minimum for anything useful; six to ten typical posts gives a clear picture. More posts help most with spotting signature phrases and how you open.

Will removing AI phrases fool AI detectors?

That isn't the goal and nothing guarantees it. The point is captions that read naturally to your followers and sound like the rest of your feed.
