Core FeatureFeatures
One platform for humanizing, detecting, and verifying AI text — with more tools on the way.
Rewrites AI-generated text sentence by sentence, introducing natural variation in word choice and rhythm. Tuned specifically against GPTZero's perplexity and burstiness scoring.
Core FeaturePowered by GPTZero Model 4.4b — the same model used by universities and publishers. Sentence-level breakdown shows exactly what's triggering the score.
Included FreeLight Touch makes minimal changes. Selective rewrites only the AI-flagged sentences. Complete rebuilds every sentence from scratch. Choose based on how much you need.
Set the tone (Natural, Professional, Casual, Academic) and reading level (High School → Graduate). Useful for students matching their own voice and professionals matching brand style.
Paid PlansHumanize and detect AI text in over 50 languages. Works on essays, reports, and content written in any major language.
Starter+Humanize text directly on any webpage — Google Docs, email drafts, or anywhere you write online. No copy-pasting required.
Coming SoonAI detectors measure perplexity (how predictable each word choice is) and burstiness (how much sentence length varies). AI text fails both — every word is the statistically safe choice, and every sentence lands at roughly the same complexity level.
Our rewriter is trained to introduce natural variation. Some sentences get shorter. Some word choices get less predictable — not wrong, just less automatic. The result is text that reads the same but scores differently.
Before
"The implementation of AI in educational settings has significantly impacted how students approach academic writing tasks."
After
"AI in classrooms has changed how students write. Not always for the worse — but the shift is real, and most instructors haven't caught up with it."
