Paste your protocol, get the SPIRIT 2025 checklist pre-filled
Paste the whole protocol. We look for where each of the 34 items is covered and show you the sentence, so you can fill the gaps before you submit it. We check that the wording is there, not that it is good.
No account for your first result. Your text is read by fixed rules, not an AI model, and we do not keep it.
SPIRIT is for the protocol; when the trial is reported, the matching checklist is CONSORT 2025. The sample size item asks for every assumption: the sample size calculator writes that paragraph.
Questions
What is SPIRIT 2025?
The reporting guideline for protocols of randomised trials, updated in 2025: 34 items, with a new open science section, more on harms and on the interventions, and a new item on patient and public involvement.
Who asks for the SPIRIT checklist?
Journals that publish protocols, many funders and ethics committees, and trial registries expect a protocol to cover the SPIRIT items.
Does a match mean the item is covered well?
No. A match shows where the wording is, so you can check it. Not found means none of the usual wording was seen; the item may be there in other words.
Is my protocol stored?
No. It is read by fixed rules, not an AI model, and not kept.
