AI LinkedIn Post Generator
Give it a topic and one real detail from your work. It writes a LinkedIn post, then checks the draft for the patterns readers spot as AI before you see it. Free, no sign-up.
No detail? It writes an opinion or how-to and won't invent a story.
How it works
The generator writes one post of 120 to 250 words, with a short first line, a single clear point and at most 2 hashtags. It's told to avoid the 110 words, 44 stock phrases and 39 sentence patterns Postbrander bans, and the finished draft is scored against them.
If you give it a real detail, the post is built around it. If you don't, it writes an opinion or a how-to, and checks that it hasn't made up an experience for you. Either way, a second pass compares the draft with what you wrote and lists any figure or detail you didn't give it, so you can check it before posting. That matters since LinkedIn added a "Seems like AI slop" report button.
To polish the result, run it through the post analyser, add emphasis with the formatter, or see where it cuts off with the post preview.
Frequently asked questions
Is this AI LinkedIn post generator free?+
Yes, with no sign-up. You can make 5 drafts every 10 minutes. It uses the same writing model as Postbrander, but it doesn't know your voice, so treat each draft as a starting point. For drafts in your own voice, scheduling and post stats, Postbrander's free plan covers 7 posts a month.
Will the post sound like AI wrote it?+
It's built not to. The writer is given Postbrander's list of 110 banned words, 44 stock phrases and 39 sentence patterns that readers link with AI, and every draft is scored against them before you see it. The page shows the score and anything it caught, so you know what to edit.
Why should I add a real detail?+
Because it's the difference between your post and anyone's. LinkedIn describes AI slop as polished posts with no substance, and lets anyone report them. A client question, a number from your work or a lesson you learned gives the post something only you could say. Without one, the generator writes an opinion or how-to and won't invent a story.
Can I post the draft straight to LinkedIn?+
You can copy it, but read it first and make it yours. Check any number or claim, change words you wouldn't use, and add a line only you could write. Then paste it into LinkedIn. If you want it scheduled and published for you, Postbrander does that through LinkedIn's official API.
How is this different from Postbrander?+
This tool writes one draft from a topic. Postbrander builds a voice profile from your own posts, asks a couple of questions to pull out real detail, fact-checks claims, schedules the post, adds a first comment and shows how it did, including saves, sends and link clicks.
