Humanize an AI LinkedIn post: your voice, without the ChatGPT tone.
Rephrase’s custom voice learns your style from three of your posts. Undetectable posts, your editorial line preserved.
You have the substance, but not always the time to write. The AI first drafts are too flat. Rephrase, using your own voice, produces posts that hold your line: your vocabulary, your rhythm, your quirks. In 2 minutes instead of 20.

Why an AI LinkedIn post is spotted instantly
The LinkedIn algorithm is not (yet) an AI detector. But your audience is. Posts generated by raw ChatGPT always follow the same template: one-line shock opener, bullet-point list, rhetorical-question close. Past the third post, your audience tunes out and the algorithm notices the engagement drop.
AI patterns visible to the naked eye: "5 lessons I learned...", "Here are 3 truths nobody tells you...", "That is all you need to know." These phrasings have become the marker of a post that was not personally written.
How to humanize a LinkedIn post with your own voice
Three steps: 1) paste 3 to 5 of your old posts into Rephrase to create your custom voice, and the tool extracts your rhythm, your connectors, your vocabulary; 2) generate your new post with ChatGPT or Claude for the substance; 3) paste it into Rephrase with your voice turned on. The result sounds like you, not like ChatGPT.
You can create several voices, a "short / punchy post" one and a "long / storytelling post" one, for example, and switch depending on the format. Each voice is private and encrypted.
