How to get a post worth publishing
Generic input produces generic output. Instead of "leadership tips", write the specific thing that happened: "we cut our weekly status meeting and shipped faster". The more concrete the topic, the less the draft reads like AI.
Add a writing sample whenever you can. Two or three paragraphs of your own posts is enough for the model to pick up your sentence length, your punctuation habits and whether you use humour or plain statements.
Edit before you post
Treat the output as a first draft. Cut the first line if it restates the topic, swap any word you would never say out loud, and end on a single clear thought rather than a question you do not want answered.
Frequently asked questions
Is the AI post generator free?
Yes. You can generate posts here without an account. There is an hourly fair-use limit; a PostingPilot trial removes it and adds scheduling and direct publishing.
Can it write in my own voice?
Paste 200–2,000 characters of your own writing into the writing sample field. The generator mirrors your sentence length, rhythm and tone rather than defaulting to generic marketing copy.
Which platforms are supported?
LinkedIn, X (Twitter), Instagram, Facebook, Threads and YouTube, plus a generic format for cross-posting. Each one uses different length and structure guidance.
Can I publish the post directly?
Not from this free tool. Inside PostingPilot you can schedule the generated post and publish it straight to your connected channels.
