Indahl Research Checks

Checks you bring. Name a paper by DOI or arXiv id, or paste text from one, and get an answer from public records and arithmetic, with what was read and what could not be read.

paper_check reads the notices registered in Crossref for a paper (retractions, corrections and expressions of concern, from publishers and entries Crossref attributes to Retraction Watch), the current arXiv version and any withdrawal in its comment, whether a page answers at each code and data link stated in the abstract, and whether the QIA or IRIS index has read it. A record that does not exist reads NO_RECORD, not clean.

check_reported_statistics recomputes every reported t, F, chi-square, r and z statistic with its p value, and every count-and-percentage pair, from the paper's own numbers, allowing for rounding. Each row gives the quoted text, the stated and recomputed values and one of ABOVE, BELOW, CONSISTENT or CANNOT_TELL. Rows where the text mentions a one-tailed test or a correction read CANNOT_TELL with the reason. Arithmetic only, no model.

what_changed lists which live indahl.ai checks changed since a time, separating changes in content from moves in dates alone. find_study, arxiv_version_drift and link_rot read the indahl.ai indexes.

Every tool is read-only. Every answer carries a signed receipt: the SHA-256 of the answer and of the request with an Ed25519 signature from the key published at https://indahl.ai/.well-known/jwks.json. A receipt shows indahl.ai produced the answer to that request. It does not show the answer is right. No account and no key are needed.
