The Musely AI Fact Checker is a free online tool that reviews any text you paste and flags its factual claims. It isolates each claim, such as a statistic, date, quote, or scientific statement, rates how well-supported it appears, and recommends source types to confirm it. You pick from 3 presets, 10 subject domains, and a strictness level, then choose a quick verdict or a detailed claim-by-claim breakdown. It is an AI assistant that surfaces claims and sources for you to review, not a guarantee of accuracy, so always confirm flagged claims against primary sources.
What the fact checker can do
Checking
🤖Controls & Access
Check your text in three steps
Paste the text or claim
Drop in a viral post, a forwarded message, a research paragraph, or marketing copy. There is no length limit on what you paste, so a single line or a long passage both work.
Pick a preset and settings
Choose a preset such as News & Social Media Claim Check, set one of 10 domains, the claim types to focus on, a strictness level, and whether to suggest sources to verify against.
Review the breakdown
Read the claim-by-claim breakdown with optional plausibility ratings, then confirm each flagged claim against the suggested primary sources before you share, cite, or publish.
Who uses the fact checker
Vet claims before filing
I paste a politician's statement and get each claim broken out with what to verify. It does not hand me a verdict, it points me to the records, so I still confirm before I file. Saves me about an hour of triage per story.
Check facts in a draft
Before I submit, I run my draft through the Research & Citation Check preset. It flags any statistic or date without a source so I can chase the original study. It caught two figures I had remembered wrong.
Clean up claims before publishing
Strict mode catches every fastest or number-one in our copy that we cannot back up. Now legal review is faster because the unverifiable claims are already flagged with a note to add a source.
Teach students to spot claims
I paste a forwarded message and the breakdown shows students which sentences are checkable claims versus opinion. The source suggestions turn it into a lesson on where to look, not just what to believe.
Screen reports for shaky claims
When a report lands, I run the key sections through the History and Law domains. It surfaces the claims that need a primary source, which lets me focus my reading instead of re-checking everything line by line.
Check a post before resharing
I paste anything that sounds too neat before I share it. The plausibility rating and the list of what to verify stop me from passing along a viral claim that does not hold up. Takes about ten seconds.

Fact checker FAQ
The best fact checker depends on your goal. Editorial sites like PolitiFact, FactCheck.org, and Snopes publish verdicts on selected public claims, while the Musely AI Fact Checker lets you paste your own text and get a claim-by-claim breakdown with what to verify. It offers 3 presets, 10 domains, and an optional plausibility rating, and acts as an assistant that flags claims for you to confirm against primary sources.
PolitiFact and Snopes rate claims their editors choose, and a general chatbot gives an open-ended answer. The Musely AI Fact Checker takes the text you paste and returns a structured, claim-by-claim breakdown with ratings, 3 presets, 10 domains, and suggested source types. It is built to flag claims for your review, not to hand down a single verdict.
The Musely AI Fact Checker is an assistant, not a final authority. It isolates each claim, rates how well-supported it appears, and suggests sources, but it does not guarantee accuracy or assert definitive truth. Always confirm flagged claims against primary sources such as official data, peer-reviewed studies, or original records before relying on them.
It focuses on the factual claims you choose: statistics and numbers, dates and timelines, direct quotes, named people, scientific and medical statements, historical events, geographic facts, cause-and-effect claims, and superlatives like first or only. You can also narrow it to 10 subject domains, from politics and science to history and finance, for more relevant context.
Yes. Turn on Suggest Sources to Verify Against and the Musely AI Fact Checker lists the source types to consult for each claim, such as official statistics, peer-reviewed studies, court records, or primary documents. It points you toward evidence to confirm a claim yourself rather than asking you to take the verdict on trust.
The Musely AI Fact Checker is free to start with no credit card. You can paste a claim or passage and get a breakdown on the free tier, with paid plans on the Creator Plan at $19.9/mo for higher volume. It runs in the cloud and returns a result in seconds.
