Humanize AI-generated marketing copy
Marketing copy fails in a specific way when a model writes it: everything is "seamless", "effortless" and "designed for you", every paragraph ends on a benefit, and nothing has a voice. Readers have learned to skim past that register. AntiGPT rewrites copy so it sounds like a specific company talking to a specific customer, which is the only kind of copy that converts.
Why AI copy reads flat
Language models are trained to produce the most probable next word, and in marketing that probability is heavily weighted toward the last decade of SaaS landing pages. The result is fluent, positive and interchangeable. Detectors flag it for the same reason customers ignore it: it is too predictable. Rhythm is even, verbs are weak, claims are generic, and there is no friction: no admission of what the product is not for, no specific number, no line that could only have come from this team.
Humanizing does not add hype. It does the opposite: it makes the copy plainer, more specific and more uneven, which is what human writing looks like. Aggressive mode with the Marketing readability setting is tuned for this: it will cut the adjective pile-ups and give sentences a beat.
A workflow for pages and ads
Start with the draft's structure: headline, subhead, three sections, a call to action. Paste one section at a time. For headlines, paste five candidates together so the rewrite gives you variation to choose from rather than a single answer. Ads and social posts are short enough to rewrite in one request even on the free plan.
After each rewrite, read it out loud. Copy that a person can say without stumbling is copy a person will read. Then run the detector, not because your customers will, but because a high estimated-AI score is a reliable proxy for "this sounds like everyone else". Aim for the version that scores lower and sounds like you, and keep the specific claims you can actually support.
Keep the facts, lose the filler
Any number, price, guarantee or comparison in the draft must be one you can defend; a rewrite will not add caveats for you. Keep the product's real vocabulary (feature names, plan names, the words customers use in support tickets) and let the tool rework everything around them. If a rewrite drops a required legal line or a claim qualifier, put it back by hand.
Brand voice guidelines translate well into the mode and readability settings: Standard for consumer products, Journalist for editorial-style content marketing, Marketing for direct-response pages where every line is earning its place.
Teams and volume
Agencies and content teams usually run this at volume: dozens of product descriptions or a week of social posts at once. The Pro and Max plans raise both the monthly allowance and the per-request cap and switch on long-text chunking, so a whole page can go through in one action. Words are metered on input only, and a failed request is never charged.

Most project tools make you do the admin. Ours does it for you: tasks pull from your calendar, updates post themselves, and the Monday status email writes itself from what actually shipped. Teams of five to fifty switch in an afternoon. The importer is the boring part we spent a year on.
Specific mechanism instead of "seamless", a real constraint (five to fifty), one concrete detail (the importer), and no exclamation mark. It reads as a company, not a template.

Questions
Will it change my brand voice?
It removes the generic register; your terminology, claims and structure stay. Use the readability setting to match your usual tone.
Can I rewrite a whole landing page at once?
On Pro and Max, yes: long text is chunked at paragraph boundaries. On Free and Starter, paste a section at a time.
Does the detector matter for marketing?
Customers rarely run one, but the score is a good proxy for how generic the copy sounds.
