Claims vs Evidence Checker Free & Online for Papers

See at a glance which sentences carry numbers and which only carry confidence.

What this tool does

This tool audits a passage by sorting every sentence into evidence, claim, or hedged claim using visible cues only. Sentences with numbers, percentages, or statistical notation count as evidence. Sentences with hedging words such as may, might, or suggests count as hedged claims. Everything else counts as a plain claim. The result is a table that shows, sentence by sentence, how much of a passage is actually backed by figures.

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 results or discussion section and press the audit button. Read the table row by row and look for long runs of claims with no evidence rows between them. Those are the spots worth checking against the data tables, because a confident-sounding paragraph can contain very little measurable support. A good habit is to read the table twice: once for the overall balance of evidence and claims, and once to pick out the single strongest and weakest sentences for closer inspection.

Worked example

Take three sentences: “Sleep improved recall by 23% (p < 0.01). This suggests sleep may support learning. Sleep is essential for students." The tool labels the first as evidence, because it carries a percentage and a p-value, the second as a hedged claim, because of suggests and may, and the third as a plain claim, because it asserts without numbers or hedging. The table makes the slide from data to opinion visible in seconds.

How to read the results

The output is a two-column table: each sentence beside its class, with a note explaining the rules used. Counts are not shown as a score, because a passage can legitimately contain many claims when it is interpreting results. What matters is the pattern: evidence should cluster around the main findings, and hedges should appear where conclusions go beyond the data.

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 is a cue-based heuristic, not a judgement of truth. A sentence can carry numbers and still be misleading, and a careful claim can be true without any figure in the same sentence. Statistical notation varies, so unusual formats may be missed. The tool flags where to look, it never decides whether a claim is right.

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.
