Why most AI captions sound like a business student on LinkedIn
You know the problem. You type write me an Instagram caption into ChatGPT, hit enter, and get back: In today's fast-paced world, it is more important than ever.... Three emojis. Four hashtags. Zero personality. Exactly the kind of algorithm-fodder your audience is already tired of scrolling.
The problem is not the AI. The problem is the prompt. A language model is a mirror of your instruction. Type write something cool and you get generic. Give the model context, format, tone, and goal, and you get something that actually clicks.
In this article you get seven prompt templates we have tested at Brandlix in real customer posts. No theory. Copy, adapt, post. Each prompt comes with an example input and an example output so you see what falls out before you try it yourself.
Prompt 1: The hook generator for Reels and TikTok
The first 1.5 seconds decide whether someone stays. Algorithms measure watch time ruthlessly. A weak opener costs you reach.
Write 10 different hook options for a Reel by [account description]. Topic: [topic]. Each hook a maximum of 8 words, spoken language, no question at the start. Vary between pattern interrupt, contrarian statement, concrete number, personal confession. Deliver as a numbered list.
Example input: Account: personal trainer in Berlin. Topic: why cardio alone does not work for fat loss.
Example output (excerpt):
- I did six months of cardio. Nothing.
- Cardio is the most expensive waste of time in the gym.
- 87 percent of my clients make this mistake.
- Without strength training you just become a smaller version of yourself.
Prompt 2: The story format for emotional posts
Stories convert better than lists because they speak to the limbic system. But most AI tools write stories like Wikipedia entries.
Write a caption in story format with this structure: sentence 1 is a cliffhanger. Sentences 2-4 are setting. Sentences 5-8 are conflict. Sentences 9-12 are resolution with a takeaway. The last sentence is the bridge to my service [service]. Topic: [experience]. Style: personal, no adjective chains, short sentences.
Example input: Service: branding for coaches. Experience: client wanted a new logo, ended up redoing her entire positioning.
The output then typically opens with something like She wanted a new logo. Three weeks later she had a new business. That stops the thumb.
Prompt 3: The carousel build in 7 slides
Carousels have the highest save rate on Instagram and LinkedIn. But they need structure, otherwise they are just stock photos with text.
Build a 7-slide carousel on the topic [topic]. Slide 1: hook with a pain point. Slides 2-3: deepen the problem with a concrete example. Slide 4: reframe or aha moment. Slides 5-6: concrete steps or framework. Slide 7: call to action with a verb. Each slide a maximum of 25 words. For each slide also suggest a visual.
The nice thing about this prompt: you do not just get text, you get a whole post idea. The visual suggestions save you the next argument with your designer.
Prompt 4: The listicle generator
Lists work because the brain loves them. Defined beginning, defined end, clear expectation. But AI tends to make them too long.
Write a listicle post with exactly [N] points. List title: [title]. Each point: a bold term, one explanatory sentence, one concrete real-world example. No intro longer than two sentences. Close with a pointed statement, not a question.
Example input: Title: five tools that save every solopreneur 10 hours a week.
The result is scannable, shareable, and saveable. Exactly what the algorithm rewards.
Prompt 5: The question hook
Questions at the start are a double-edged sword. Badly framed they sound like marketing bullshit. Well framed they create engagement.
Invent five unexpected questions a [target audience] asks themselves at night when they think about [topic]. No rhetorical questions. No yes-no questions. Each question should reveal a hidden conflict. Format: questions only, no explanation.
These questions then become your hooks. Take the strongest one, paste it at the top of your caption, and you have an opener that almost never sounds generic.
Prompt 6: Pain-point to call-to-action
Selling without addressing pain is preaching to an empty hall. But pain alone is manipulation. You need the bridge.
Write a caption with this structure: 1. Pain point in one specific and honest sentence. 2. Amplify the pain with a consequence the reader knows. 3. Reframe that shows it is not the reader's fault. 4. Solution outline in three points. 5. CTA that is not click the link but a concrete small action. Topic: [offer].
This prompt is dangerously good for conversion posts. Do not use it too often, or all your posts will read like sales funnels.
Prompt 7: Migration into your own brand voice
The most important prompt of all. Because the other six prompts produce output that still sounds like a model. Only this step makes it unmistakable.
Here are three of my best posts from the last 90 days: [post 1], [post 2], [post 3]. Analyze my writing style: sentence length, favorite words, pauses, typical transitions, irony level, formal or casual address. Then rewrite the following draft as if I had written it myself: [draft]. No new arguments, only tone adjustment.
This is exactly the step where Brandlix makes a difference.
What Brandlix does differently
The seven prompts above are usable in any AI tool. But they share a weakness: you have to ship your brand voice with every single post.
Brandlix learns your brand voice once from your best posts. Every following post, every caption, every carousel slide comes out in the right tone automatically. You stop managing prompts - you describe what you want, the AI agent handles the rest.
On top of that: Brandlix does not just write captions. It knows which hashtags fit your niche, which posting time your audience is online, and which platform likes which format. That is the difference between a wrapper around ChatGPT and an actual workflow.
If you copy the seven prompts above, you have a good day at the office. If you set up Brandlix, you have a workflow that delivers every day.
