“Heavy mode dropped my Turnitin AI score from 62% to 3%. My argument structure stayed intact — I had to fix maybe two sentences myself.”

“Good results for long-form posts. Short paragraphs occasionally need a light edit, but for 800+ word pieces it genuinely saves time.”

“The 5 free uses were enough to test on real drafts. GPTZero moved to 97% human after one pass. Upgraded the same day.”

“Medium mode works well for client copy. Heavy mode is strong but I sometimes rewrite the opening sentence after processing.”

“Technical terminology came through unchanged. Citations were preserved exactly. That alone puts it ahead of everything else I tested.”

“Solid for blog content. Short social captions sometimes need a second pass, but the base output is clean enough to work from.”

“Tested 50 passages across 4 detectors — GPTZero, Turnitin, Originality, ZeroGPT. AI2Human passed all of them. Nothing else came close.”

“We run 30+ articles a week through it. The Ultimate plan handles the volume fine. Processing could be a bit faster at peak hours.”

“Heavy mode output reads naturally out loud. My editors haven't flagged it once in three months of daily use.”

“It preserves my phrasing while removing the AI patterns. My advisor noticed the writing felt more like me than my previous drafts.”

“We use it as the final step before client delivery. Natural output overall — a few pieces still need a read-through before sending.”

“Fast output, clean results. Saves hours compared to rewriting manually. I still do a quick read before delivery but it's mostly solid.”

“Both my lab report and lit review passed Turnitin AI check on the first try. Didn't touch a single sentence after processing.”

“Good for caption drafts and email copy. Some outputs need a small tone tweak but the base is always solid enough to work from.”

“Ran our entire product docs through it. Investors specifically said the writing felt more human than our earlier copy. That's a real win.”
