Gemini can do anything. Writing a LinkedIn post that sounds like you isn’t one of them.
Google Gemini is a powerful general-purpose AI. Ask it to write a LinkedIn post and it will. You'll get something grammatically correct, reasonably structured, and completely interchangeable with a thousand other LinkedIn posts. The problem isn't the model. It's that Gemini doesn't know you.
Capable of anything. Missing the one thing that matters.
“Uncertainty is uncomfortable. But it’s also where growth happens. As a leader, I’ve learned that the ability to navigate ambiguity — to make decisions without complete information — is one of the most valuable skills you can develop. The best leaders don’t wait for certainty. They build the capacity to act clearly in its absence. Where are you finding the most uncertainty right now?”
We had a board meeting on Wednesday where I presented three scenarios — and every single one of them felt equally likely. I’ve never done that before. I’ve always had a view. This time I genuinely didn’t.
One of the board members said something afterward that I’m still turning over: “The fact that you can hold three scenarios at once without collapsing them into one is actually a leadership skill. Most people can’t do that.”
I’m not sure if she was right or being kind. Either way, I wrote it down.
Every general AI has the same problem: no access to your week.
The prompt is the problem
To get a good post from Gemini, you need a good prompt. A good prompt requires knowing what's interesting about your week. Figuring that out is the whole job. Say Something does that step for you through a structured interview.
Internet-trained voice vs. your voice
Gemini generates text that sounds like the internet. The internet sounds like everyone on LinkedIn already. What performs on LinkedIn is specific, firsthand, and slightly unexpected — things Gemini can only approximate without knowing your actual situation.
No kill list
Gemini will write the generic patterns — the wisdom lists, the inspirational closes, the 'what do you think?' sign-offs. Say Something blocks them by default. The 14-rule kill list exists because those patterns are the fastest way to sound like AI on LinkedIn.
General AI for general problems. Specific tools for specific ones.
Gemini is an excellent tool. For research, summarization, drafting emails, analyzing data — it’s hard to beat. Writing a LinkedIn post that sounds like a specific human with a specific week is not a general-purpose problem.
It requires knowing what happened. Say Something asks. Try the five-minute conversation or see posts that came out the other side.
Common questions.
Can I just tell Gemini more details about my week to get a better post?
Yes, and the output will improve. But deciding which details to share is itself the creative work — and most people underestimate what’s interesting about their own experience. Say Something asks targeted questions that surface the details you wouldn’t think to include.
Does Gemini have LinkedIn-specific features?
Gemini has LinkedIn integration in some Google Workspace products, but it’s not purpose-built for LinkedIn post writing. Say Something is designed around LinkedIn specifically — the character limits, the engagement patterns, and the format rules that separate posts that read as authentic from those that read as AI-generated.
Is this just a Claude wrapper?
Say Something uses Claude under the hood with a purpose-built system prompt, interview structure, and kill list — tuned specifically for LinkedIn authenticity. It’s not a general-purpose AI chat interface with a different skin. The workflow is the product.
Is Say Something free?
Yes. You can write posts, grade existing ones, and check for AI-sounding language — all free, no account required.
