Checks for the paper in front of you
Three small tools from Dimitri's Letters. They search real databases or run in your browser, show you what they did, and need no sign-in.
-
Traffic Light
Describe a research idea. It is checked against PubMed and ClinicalTrials.gov and gets a green, amber or red light with a one-line reason.
Three checks a day. Uses AI to weigh what the searches found.
Check an idea -
Reference Check
Paste your reference list in any style. Every reference with a DOI or PMID is matched against PubMed and Crossref, with any retraction, correction or expression of concern.
Ten checks a day, 10 DOIs or PMIDs each. Code does the checking, not AI.
Check references -
Authorship Sheet
Agree who does what before the work starts: a CRediT statement, the ICMJE criteria, overlap warnings and a kickoff agreement to discuss.
No limit. It runs in your browser and sends nothing to us.
