The internet already fell for these.
Odds are, so did you. Misinformation doesn't look like misinformation. It looks like a real photo, a trusted-sounding account, or a claim that's technically true.
The shark that “swam onto the highway”
RECYCLEDThe same flood photo gets recycled every hurricane season with a new city's name on it. It's real, just not from this storm, and not from this year.
The chocolate experience that never existed
AI-GENERATEDAI-generated marketing images sold out a “Willy Wonka” event in Glasgow in 2024. Families showed up to an empty warehouse. The photos looked real enough to book tickets.
Hotdogs and cigarettes have the same cancer risk
Processed meat and cigarettes are both classified as level-one carcinogens, but cigarettes multiply cancer risk by as much as 20×, far worse than an occasional hotdog.
The claim, the account, the media: a post can go wrong on any of them, and checking takes longer than sharing. What the Fact checks all three in seconds.

Everything you'd want to know before you download.
What is What the Fact?+
What the Fact is a free fact-checking app for iOS and Android. Share a social media post or video to it and it tells you whether the claim is accurate or misleading, whether the account is trustworthy, and whether the image or video is real or AI-generated, with a confidence score and links to every source used.
How much does it cost?+
What the Fact is free to download and start checking. Any premium options will always leave a meaningful free tier. The goal is to make fact-checking accessible, not gated.
Which platforms can I check?+
Share or paste a link from X, Facebook, Instagram, Threads, LinkedIn, Reddit, YouTube, or TikTok, straight from the share sheet. You can also check a post you've screenshotted when a link isn't available.
Is my data private?+
We analyze the public post you share, not your accounts or your contacts. Your verification history is yours, saved so you can revisit past checks.
What sources do you check against?+
Every claim is weighed against 6+ independent, pre-vetted outlets and existing fact-checks. An outlet only counts toward the analysis after we've evaluated its history: how long it's been publishing, how often it posts, and what it actually publishes. Every analysis links to the sources it used.
How does the analysis actually work?+
Three checks run on every post: the claim is cross-checked against vetted coverage; the posting account is profiled for its age, posting pattern, and automation signals; and the media is fingerprinted and run through synthetic-media detection models that flag AI generation and manipulation. The three signals combine into one clear answer with a confidence score.
How accurate is the analysis?+
Every analysis comes with a confidence score and a full signal breakdown, and links to the sources behind it. When the evidence is genuinely mixed, we mark a post Can't Verify rather than guessing.
What does 'Can't Verify' mean?+
It means the claim can't be confirmed or debunked with confidence right now, often because sources disagree or the story is still developing. It's a signal to wait, not to trust or dismiss.
Can it detect deepfakes and AI-generated media?+
Yes. Media is run through synthetic-media detection models that flag AI-generated images and video, edits, and manipulations. It's a core part of every check.
