Risk checking is always free. You only pay when you choose to rewrite with Humanize.
Paste your Vietnamese or English writing into the checker — no account needed.
The tool estimates the risk of being flagged by AI systems, with a confidence level, and highlights the highest-risk sentences — no true/false verdict.
For sentences scored as high risk, Humanize helps rewrite them in your own intent but more naturally, keeping the meaning intact.
When your writing scores high risk, Humanize rewrites it to keep your meaning but sound more natural — not a tool for dodging detection, but a tool to help you write with more confidence.
No tool — including this one — guarantees beating every detection system. This is a natural-writing aid, not a cheating tool.
Supports Vietnamese and English, with an architecture ready to add more languages.
Always shows a confidence level alongside the risk score, openly stating the tool's limits instead of absolute claims.
Designed to protect genuine writers from being wrongly suspected of using AI — not a tool for cheating or dodging accountability.
Each group has its own needs, but everyone uses the tool on the same principle: protect genuine writers, never enable cheating.
Check your own work before submitting to avoid being wrongly suspected; if it gets falsely flagged, rewrite it to sound more natural.
Bring drafts to a natural, on-brand voice before you publish.
Write with confidence in a second language without being wrongly suspected of using AI.
Shared guardrail: Mepo8 is a neutral aid for natural writing and avoiding false flags — not a tool for cheating or dodging accountability. We never advertise beating any specific detection system.
Check results are for reference, not a verdict. We believe being honest about the limits matters more than an impressive-sounding number.
