NeverPrompted

For non-native English professionals who polish with AI

You write fluently, in your second, third, or fourth language, and you run it through an assistant to catch grammar you're less sure of. That's not a shortcut, it's what any careful writer does when writing outside their first language. The problem is what tends to happen next: the assistant doesn't just fix your grammar, it also flattens your actual phrasing, the word order and idiom choices that mark your writing as yours, into the generic register it defaults to. You end up correct and unrecognisable in the same paragraph.

This isn’t about hiding that you used help

Let's be clear about what this page is and isn't. Using an assistant to check grammar, catch awkward constructions, or confirm a phrase sounds natural is a completely reasonable thing to do, and nobody honest would tell you to stop. The issue is a side effect: heavy AI polishing doesn't stop at grammar, it tends to overwrite your actual sentence rhythm and word choices with the assistant's own preferred phrasing, which is often blander and more uniform than what you'd have written with just the grammar fixed.

That matters for two separate reasons. First, your writing stops sounding like you, which is a loss on its own terms if you've spent years developing a professional voice in a second language. Second, ironically, heavily-smoothed AI phrasing is exactly the pattern that trips AI-detection systems, meaning the polish you used to sound more careful can end up making careful, genuine writing look machine-generated.

Checking what changed, and why

NeverPrompted runs entirely on your device, nothing you paste is ever uploaded. It checks for a statistical AI watermark and, separately, measures how far your text's style has drifted from a reference corpus of real contemporary prose, catching things like uniform sentence length, stock transitional phrases, and hedging patterns that read as generic rather than as your idiom.

Where the assistant's polish went further than grammar and started overwriting your actual phrasing, the rewrite tool can push back the other way: targeting the specific AI tells (stock phrases, em dashes used as connectors, unnaturally even sentence rhythm) while preserving your meaning and, as much as the settings allow, your original word choices. It shows a diff before anything is applied, so you're deciding, sentence by sentence, whether a change is a genuine grammar fix worth keeping or a flattening you'd rather undo.

What honest limits look like here

No tool, this one included, can promise that your writing will never be misjudged by someone else's detector, especially since detectors are known to flag non-native phrasing patterns more often even when nothing was AI-generated. What NeverPrompted can do is give you a concrete way to check your own draft before you send it, and a way to dial back over-polishing that erased your actual voice, which is generally the more useful problem to solve since it's the one you can actually act on.

It's also worth saying directly: if a document you're checking carries a genuine watermark from an AI vendor you have no relationship with, nobody outside that vendor holds the key needed to guarantee defeating it, and no honest tool claims otherwise. Free gives you unlimited checking and a weekly rewrite budget; Pro removes the weekly limit, upgrades the on-device rewriting model, and adds a dated PDF report if you need a record of what you checked before submitting something important.

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.

Questions people actually ask

Is it dishonest to use an AI assistant to fix my grammar?
No. Using tools to check and correct language you're less confident in is a normal part of writing outside your first language, and no reasonable reader or institution expects otherwise. The concern this page addresses is narrower: that the same polishing step can quietly overwrite your actual phrasing, not just your grammar errors.
Will this make my writing sound less fluent or more clunky, to compensate?
No, that's not the goal. The rewrite tool targets specific AI tells (stock transitions, over-even sentence rhythm, unnecessary hedging), not fluency itself. It's editing toward your own natural phrasing where the assistant over-smoothed it, not toward incorrect or informal English.
My colleague asked me to check if their report sounds AI-written. Can I use NeverPrompted for that?
NeverPrompted is built for checking and improving your own writing, not someone else's. Using it to evaluate a colleague's or student's submitted work is a different situation with different stakes and expectations. If you need to screen writing that isn't yours, our sibling product Learnaway (learnaway.ai) is built for that purpose.
