Use the checker for learning

Permitted use

Use the checker to review Chinese text you wrote or have permission to submit, understand grammar corrections and explanations, and practise sentence patterns. Review AI feedback yourself: it can be incomplete or incorrect.

Follow your school's or institution's rules on AI assistance. The service is for feedback on your own writing, not for completing assignments or generating work to submit dishonestly as your own.

Prohibited content and requests

• Adult and NSFW generation is prohibited. Do not use the checker to generate, rewrite, improve, expand, or request adult, sexually explicit, pornographic, or NSFW content, including sexual roleplay. This applies to corrections, natural rewrites, examples, and explanations.
• Do not submit or request content involving sexual exploitation, sexual content involving minors, non-consensual sexual activity, or intimate content shared without consent.
• Do not use the service to create threats, targeted harassment, hate content, instructions for violence or wrongdoing, or content that promotes self-harm or exploitation.
• Do not use it for fraud, scams, phishing, impersonation, spam, or other illegal or deceptive activity.
• Do not submit private or sensitive information about yourself or others, or material you do not have the right to use. Respect privacy and intellectual property rights.

Service access and safeguards

Do not try to bypass content safeguards, usage limits, access controls, or payment requirements. Do not share or resell account access, scrape or automate bulk checks without permission, disrupt the service, or use prompts disguised as grammar exercises to obtain prohibited content.

Enforcement and reporting

We may refuse requests, restrict access, or suspend accounts when we identify violations. These rules do not guarantee that every prohibited input or output will be detected.
