Records, research, full statements. We look for where a claim began, not just where it was shared.

Heard something?
Is it true?
We break it down, check the evidence, and tell you what we found—and why.
What’s true. What’s not. And how we got there.
02 / Recently checked
Seen. Heard. Checked.
No checks yet. Try a claim above to get started.
03 / The evidenceDon’t just
Don’t just
take our word.
A conclusion is only useful if you can see what’s behind it. We link to the evidence so you can take a closer look, too.

Context changes
the story.
A real quote can still be misleading. Dates, missing details, and what a source actually proves all matter.
Sometimes,
we don’t know yet.
When the evidence is thin or conflicting, that belongs in the conclusion—not in the fine print.

TierStarting scoreSource type & examplesHow to use it
196–100Original, primary evidenceLaws, court records, official datasets, direct filings, full transcriptsBest for proving what happened or what was officially stated.
290–95High-standard independent reportingAP, Reuters, AFP; strong peer-reviewed consensus reviewsProfessional standards, corrections, named evidence and independent reporting.
382–89Established national or expert sourcesBBC, NPR, PBS, major newspapers, universities, specialist journalsStrong overall, but each article still needs a relevance and evidence check.
470–81Established local or trade reportingLocal newspapers, industry publications, named expert explainersOften useful and close to the story; scope or independence may be limited.
545–69Advocacy, partisan, or weakly sourced contentCampaign groups, opinion outlets, company blogs, anonymous aggregationMay contain facts, but incentives and missing context need extra checking.
60–44Unverified or deceptive materialAnonymous posts, altered screenshots, content farms, satire presented as newsNever enough on its own. Trace the claim back to an original source.
04 / Why IsItTrueBeing curious
Being curious
is a good thing.
We made IsItTrue for that moment when you think, “Wait, really?” The goal is simple: help you understand what you saw or heard, one claim at a time.
What can I check?
Paste a factual claim, a social post, or a link to an article. Specific claims work best. For a photo or video, describe the claim you want checked; the input currently accepts text and links.
Does a high score mean it’s definitely true?
No. The score summarizes the evidence found for a claim. It is not a probability or a guarantee. Read the conclusion, the breakdown, and the sources together.
What if there isn’t enough evidence?
We tell you what remains unconfirmed. A lack of evidence does not automatically make a claim false, and predictions cannot be confirmed before they happen.
How are the checks made?
IsItTrue uses AI and web search to break down claims and assess available evidence. It can make mistakes. Each result includes sources to help you review its reasoning.

Layer 2
Claim importance weights
The weights must total 100%. The core claim always receives the largest share.
Core claim50–80%The main thing a reader would repeat.
Cause20–35%Scored separately whenever the claim says “because.”
Amount10–20%Numbers, percentages, rankings, or scale.
Timing10–20%Dates, deadlines, or when something will happen.
Place / group10–20%Where it applies and who it affects.
“This will happen next year.”
We do not label a future event “true.” We rate how strong the forecast is, test the assumptions, and lower confidence when the date or number is overly precise.
“This happened because of that.”
We split the event and the reason into separate claims. Both must be supported. A true event does not automatically make the proposed cause true.
No evidence, no confident verdict.
One source caps the result at 74. No direct evidence caps it at 69. A source’s reputation can never replace a real evidence match.
A claim. A closer look. A clearer answer.
