Why AI-assisted posts converge on the same voice
This isn't a coincidence, it's what happens when a lot of people use the same kind of assistant with the same kind of prompt ("make this sound more professional", "tighten this up") without checking what came out. Assistants have a default register: confident but hedged, structured in short punchy lines, fond of a particular kind of dash and a particular kind of "here's the thing" opener. Apply that to a hundred different people's raw thoughts and you get a hundred posts that read as roughly the same person.
The people who built a following on LinkedIn or elsewhere usually did it with a specific, sometimes odd, recognisably theirs way of putting things: a particular kind of bluntness, a particular sense of humour, sentences that don't all land the same length. That's exactly what gets sanded off first when a post goes through a heavy AI polish pass, because it's also the part that reads as "unpolished" to an assistant optimising for smoothness.
Checking a draft before you post it
NeverPrompted runs entirely in your browser, nothing you paste gets uploaded, which is worth knowing if you're drafting something you haven't posted yet. It checks for a statistical AI watermark, and separately measures how far a draft's style sits from a reference corpus of real, varied contemporary writing, catching the specific patterns that mark a post as generically AI-polished: uniform sentence rhythm, the same handful of stock openers and transitions, an em dash doing a comma's job.
Where it finds those patterns, it proposes a rewrite and shows you the diff rather than just handing back a replacement post, since the whole point is that you know your own voice better than any model does. You accept or reject each change. Turn the rewrite strength down if you want it to only fix the obvious tells and leave your phrasing otherwise untouched, or up if a draft needs more work to sound like you again.
The honest version of what this buys you
This won't make a post go viral, and any tool that promised that would be lying to you, engagement depends on far more than sentence-level style. What it can do is give you a fast, private way to catch when a draft has drifted from your actual voice toward the generic AI-assisted register, before you post it and someone in your replies notices before you do.
It's also worth being direct: if a platform or a third party is checking your post against an undisclosed AI watermark from some other vendor, no tool, this one included, can guarantee getting past that check, since only the vendor that applied the mark holds the key to it. NeverPrompted's watermark check reports what it can detect about that; separately, the rewrite tool reduces detectable AI-style evidence in your actual wording, which is the part you can control directly. Free covers unlimited checking and a weekly rewrite budget, which is plenty for a normal posting rhythm; Pro removes the limit and adds a better rewriting model for when you're publishing more often.
Wherever this page describes a result: a detected mark is not proof of authorship, and an absent mark is not proof of human authorship. NeverPrompted's on-device rewrite can reduce detectable evidence but cannot guarantee defeating a vendor's undisclosed watermark, on any tier.
