Check whether the data behind a paper is actually available.
What this tool does
This tool finds data availability statements in a paper. It looks for a data availability section first, then picks sentences containing availability cues such as data available, deposited, repository, and DOI. A paper’s data statement is the difference between a result you can check and a result you must take on trust, and it is usually printed where few readers look.
It works fully in your browser. Nothing is uploaded to a server, and you do not need an account. Paste your text, press the button, and read the result on the same page. That makes it useful for students, researchers, and anyone who has to get through a long paper quickly without losing the important parts.
How to use it
Paste a full paper or its end matter, where data statements live, and press the verify button. Read the returned sentences and note whether the data is in a named repository with an identifier, available on request, or not stated at all. Then, for data you actually need, follow the identifier to check the deposit exists and matches the paper.
Worked example
A statement saying the datasets are available in the Zenodo repository with a DOI returns as a single clear sentence. You learn the data is deposited, the repository is named, and an identifier is given, which is the strongest form of availability, and you learned it without hunting through the final page.
How to read the results
The output is a list of data availability sentences in original order, with a count and a note when no dedicated section was found. When no statement is found at all, the tool says so plainly, because an absent statement is itself informative about a paper’s reproducibility.
Do not treat the output as a final answer. It is a starting point for your own reading. Skim the highlighted parts first, then read the full passage around anything that matters for your work. A tool can point at the likely important sentences, but only you can judge whether they are actually important for your question.
Honest limits
This finder uses headings and cue words, not verification: it cannot check whether a DOI resolves, whether a repository deposit is complete, or whether available on request ever produces data in practice. A found statement is a lead, not proof of usable data. For reuse decisions, always follow the identifier and inspect the deposit yourself.
This tool does not use artificial intelligence, and it does not understand your paper the way a human reader does. It follows fixed rules that you can inspect in the results. That is a strength when you want transparent, repeatable results, and a weakness when a passage needs real understanding, context, or judgement.
Tips for best results
Paste clean text. Remove page headers, footers, and reference lists before you paste, because they add noise to word counts and sentence scores. Work on one section at a time for long papers, and keep your original file open beside the tool so you can check anything surprising against the source. If you use the result in your own writing, always cite the original paper, never the tool output.
Frequently asked questions
Is it free? Yes. The tool is free to use online, with no sign-up and no download.
Is my text stored anywhere? No. Everything runs in your browser tab. Closing the tab removes your pasted text.
Can I trust the output completely? No tool of this kind should be trusted blindly. Use it to speed up reading and checking, then verify the important claims yourself in the original text.
