Check the claims before they become a problem.
Paste your draft, create a free account, and see which factual claims are supported, disputed, or missing evidence.
A real detector, not a guess
Scores come from an established third-party detection service, not a homegrown scoring trick.
Sentence by sentence
You get the passages that carry the signal, not one number with no explanation.
Built for the next draft
Revise flagged passages, rescan with the same detector, and compare what changed.
A trail, not a claim
Every saved version records the result and changes without pretending a score proves authorship.
A clear read, with a useful next step.
Results stay connected to a real working draft. Review the supporting detail, then carry the same text into your next check or revision.
Verdicts for individual claims
Review supported, partly supported, refuted, and not-enough-evidence claims instead of relying on one opaque score.
Sources alongside the explanation
Every claim card explains the finding and links to the sources behind it, so review stays practical.
Made for publishing workflows
Use it on newsletters, marketing copy, reports, and posts where a small unsupported claim can undermine trust.
Questions
Does the fact checker analyze text before signup?+
No. We keep fact checking behind a free account. Pasting text here prepares the draft, but no claim analysis starts until you sign up or log in.
Can a fact checker verify everything?+
No tool can settle every claim. Treat results as a research aid and review the linked evidence before making high-stakes decisions.
How much text can I check?+
Fact checking supports drafts from 300 to 10,000 characters per request. Your signed-in workspace shows the current limit as you type.
Check the draft. Then keep working.
Review AI signals, source overlap, and factual claims, then carry the same draft into your revision workflow.
