How it works
From dense prose to reviewable claims
A useful result makes uncertainty visible and sends you back to the original source.
- 1
Add factual writing
Paste text or upload a TXT, PDF or DOCX file. One clear claim is enough; shorter passages usually produce more focused results.
- 2
Review extracted claims
The checker separates checkable statements and marks each one as appearing supported, appearing contradicted or needing context.
- 3
Verify what matters
Read the explanation, inspect any returned reference leads, and confirm consequential claims against current primary sources.
Reading the report
Three statuses, not three levels of certainty
A status describes one automated assessment of one extracted claim. It does not replace a current source or subject-matter judgment.
“No checkable claims” means the service could not isolate a factual statement. It never means the whole passage is true.
Appears contradicted
The available context conflicts with the claim. Review the explanation and treat any corrected wording as a suggestion to verify.
Needs context
The statement may be subjective, ambiguous, time-sensitive or unsupported by enough information for a responsible binary status.
Method boundary
A fast hypothesis, not live-source proof
What it can do
Extract claims, surface likely conflicts, explain the assessment, and give you focused leads for further research.
What you still do
Locate the original evidence, check publication dates and context, and decide whether it supports the exact wording.

FAQ
Before you rely on a result
Factual review is a process. This tool helps decide what to investigate next.
How does this fact checker work?
It extracts factual statements from the submitted text and uses an automated language-model review to assess whether each one appears supported, appears contradicted or needs context. It is a research starting point, not independent proof or live web verification.
Does “appears supported” prove a claim is true?
No. Automated systems can be incomplete, outdated or wrong. Check important claims against a current primary source, especially for medical, legal, financial, safety or breaking-news topics.
Are the listed references verified citations?
No. The service may return source names, but they are not verified citations or direct evidence. The report labels them as reference leads so you can locate and inspect the original source before citing it.
What can I check for free?
Anonymous checks accept up to 125 words. This page accepts up to 5,000 characters so signed-in paid accounts can review longer passages within the page limit.
Can it evaluate opinions or personal experiences?
It may extract them, but subjective preferences and private experiences usually cannot be objectively verified. Those statements should appear as needing context rather than receiving a directional assessment.
What happens to submitted text?
Nothing is sent while you type. When you start a check, the text is sent to the fact-checking service for processing. Signed-in checks may be saved to account history; avoid submitting confidential material you are not allowed to share.
Does fact checking detect AI-written text?
No. Factuality and AI authorship are separate questions. Use the AI Detector for an authorship signal and this checker for a claim-by-claim factual review.
Separate questions
Review authorship or copied wording too
Factuality, AI authorship and source overlap are different signals. Check each one independently.
