How much does it cost?
| Credit | Uses (1000 words each) |
|---|
| $5 (~₹400) | ~70 humanizations |
| $10 (~₹800) | ~140 humanizations |
| $1 (~₹80) | ~14 humanizations |
That's roughly ₹6 per 1000 words — cheaper than a chai.
How does the 3-pass pipeline work?
Pass 1: Deep restructuring — not paraphrasing. Changes argument flow, injects perplexity, forces burstiness variation, eliminates 30+ banned AI words.
Pass 2: Silent audit — a separate AI call finds every remaining tell that any detector would flag.
Pass 3: Final revision — fixes all audit findings and produces the final undetectable text.
Which detectors does it bypass?
GPTZero, Turnitin (incl. AIR-1 + anti-humanizer 2025), Originality.ai, QuillBot, ZeroGPT, Copyleaks, iThenticate, Compilatio, PlagScan, and any detector using perplexity + burstiness analysis.
