Hallucinated citations虚假引用
Authors, journal, year, even a DOI can look right. If no database holds the record, RefCheck marks it likely fabricated.作者、期刊、年份甚至 DOI 都像真的，但没有任何数据库收录，就会被标为疑似伪造。

Frequently asked questions常见问题
How does RefCheck decide a citation is fake?怎么判断一条引用是假的？
Each reference is parsed and searched in Crossref and OpenAlex, then in the databases that fit its type. When several databases agree, it is real. When nothing matches, it is marked likely fabricated. If records disagree on title, authors or year, it is real with errors.
每条文献先解析，再查 Crossref 与 OpenAlex，并按类型补查其他数据库。多个库一致即为真实；都查不到标为疑似伪造；题名、作者或年份与记录不符则标为真实但有误。
Which citation styles are supported?支持哪些引用格式？
APA, MLA, Chicago, Harvard, IEEE, Vancouver and GB/T 7714, in English or Chinese. Keep one reference per line or numbered entries like [1] [2].
GB/T 7714、APA、Harvard、Chicago、IEEE、Vancouver、MLA，中英文均可。一行一条，或保留 [1] [2] 编号。
Is it free?免费吗？
3 free reference checks without an account, plus 5 more free after you sign in. Then each reference costs 1 AILatest credit. Failed lookups are refunded. Credits are valid for 1 year and extended on every top-up.
未登录一共可免费核查 3 条参考文献，登录后再免费 5 条。之后每条 1 积分。查询失败自动退回，积分 1 年有效（充值自动顺延）。
What about Chinese references?中文文献能查吗？
Yes. Chinese references are parsed too. Those that public databases cannot confirm link out to CNKI, Wanfang and Baidu Scholar for a manual check.
可以。中文文献同样会解析核对；公开库无法确认的条目会给出知网、万方、百度学术的链接，方便人工复核。
Where is my history stored?查询记录存在哪里？
Signed in, every check is saved to your AILatest account in the cloud, so you can open it on any device. Signed out, history stays only in this browser. You can delete one check or all of them anytime.
登录后，每次核查都会保存到你的 AILatest 账号（云端），换设备登录也能查看；未登录时只保存在当前浏览器。单条或全部记录都可以随时删除。

Hallucinated citation checker
How a formatted citation is matched to Crossref, OpenAlex, and other databases, and when it is marked likely fabricated.
Read guideCheck references that ChatGPT wrote
ChatGPT often invents references that look complete. Paste the list into RefCheck to match each one against Crossref, OpenAlex, and other databases.
Read guideCheck whether a cited paper was retracted
RefCheck flags retraction signals from Retraction Watch data in Crossref, and from PubMed and Europe PMC, while it checks each reference.
Read guideLook up a DOI and check it against the citation
A DOI that opens can still point at the wrong paper. RefCheck resolves it through Crossref and compares the title and authors.
Read guideHow to check if a reference is real
Check a citation by hand at doi.org or by title, or paste it into RefCheck to compare Crossref, OpenAlex, PubMed, and other databases.
Read guideCheck APA references against the real record
Paste APA reference-list entries. RefCheck checks whether each work exists and whether the year and DOI match. It does not grade italics or hanging indents.
Read guideCheck references before you submit a paper
Before you upload a manuscript, paste the reference list. RefCheck marks fabricated lines, citation errors, and retraction flags. It does not check that a paper supports your sentence.
