You read your own caption back and it sounds like everyone else. Competent, correct, completely forgettable. The problem is rarely writing ability. It is that you are writing in a voice you borrowed without noticing.
Here is the test. Take your last five posts, remove your name and logo, and hand them to someone in your industry. Could they be from any of your competitors?
If yes, you have a voice problem, not a content problem. And it is more common than the reverse, because generic writing is what happens by default.
You studied what works in your niche, absorbed the patterns, and reproduced them. That is a sensible way to learn and a terrible place to stay. Everyone else studied the same accounts.
Most people write more formally online than they speak. The moment the caption box opens, a professional voice takes over, and it is nobody in particular.
The opinion felt too strong so you softened it. The joke felt unprofessional so you cut it. The story felt self-indulgent so you trimmed it. Each edit was reasonable. Together they removed everything recognisable.
Generic is not what happens when you write badly. It is what happens when you remove everything that could be criticised.
You do not invent a voice. You already have one. The job is noticing it.
Open WhatsApp and read how you explain something to a friend. That is your voice. Compare it to your last caption. The gap between them is the problem, and it is usually large.
Voice note, two minutes, no script. Then transcribe it. You will find phrases you would never have typed, and those phrases are the most distinctive thing you have.
The ones you nearly deleted. Look at what they have in common. That is usually where your voice is strongest, because you were not editing toward safe.
Write down three things about your industry that most people in it would disagree with. If you cannot find three, you are not paying enough attention, or you are not being honest.
Real opinions are the fastest route out of generic, because nobody else has exactly yours.
A quick diagnostic. Look at your last ten posts. How many contain a sentence only you could have written, because of a specific detail, a particular opinion, or a turn of phrase that is yours? If it is under three, that is the whole problem.
People treat voice as mysterious. It is mostly mechanical, and once you can see the parts you can control them.
AI writing tools make this worse by default, and it is worth saying plainly since we make one.
Ask any AI for a caption and it gives you the average of everything it has read. The average is competent and completely anonymous. If you publish it unchanged, you have automated the exact problem this article is about.
The useful way to use these tools is the opposite. Let them handle the blank page, the structure, the first draft. Then put yourself back in: your opinion, your example, your phrasing. The draft removes the hard part of starting. You supply the part that makes it worth reading.
This is why Crevers has Brand Voice, where you paste writing you have actually done and everything generated afterwards matches how you write rather than how the internet writes. But even that is a starting point, not a substitute for having something to say.
It usually goes up. And even when it does not, you will have found out something about your audience that six months of safe posting would never have told you.
Paste a few posts you have written and Crevers learns your voice, then writes in it. Free to start, and you can switch it off any time.
