The problem

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”

A shark appearing to swim down a flooded highway next to a car's wing mirrorRECYCLED

The 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.

AnalysisReal photo, fake news

The chocolate experience that never existed

Willy's Chocolate Experience promo — a vivid, AI-generated candyland with a 'Book Now' buttonAI-GENERATED

AI-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.

AnalysisSuspicious account

Hotdogs and cigarettes have the same cancer risk

Viral post: pans of bacon, sausages and ham over the caption 'classified in the same cancer risk as cigarettes'

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.

Is the US about to launch a nuclear strike on Iran's Pickaxe Mountain?

X · 294,500 likes, 20,110 replies (X syndication, 2 Nov ~15:30 UTC); Bluesky trending topic; amplified by MTG, Hunter Biden, Ryan Grim; Daily Beast, Premium Times, Raw Story

Misleading

Tucker Carlson's post is his own unevidenced speculation: he asserts an imminent US nuclear strike on Iran built on anonymous sources, even though Trump had publicly ruled out nuclear use nine days earlier and the strike options actually under discussion are conventional bunker-busters.

Were over 500 missiles fired at Iran with major fires across Tehran?

X · 1,239 likes, 69 replies on the primary; Arabic reposts (X syndication, 2 Nov)

False

The video is real but unrelated footage: it shows the 1 June 2026 fireworks-factory explosion in Malta, not missiles hitting Iran. No 500-missile strike on Tehran or major fires across the city had occurred as of 2 November 2026.

Did Iran test a two-stage ICBM called "Rastakhiz" in this video?

X · Shared by several X accounts and Facebook reels in English and Arabic; 101 likes on primary (X syndication, 2 Nov)

Misleading

The video is real but mislabelled: it shows SpaceX's Starship lifting off from Texas on 18 November 2023, filmed by spectators at Playa Bagdad in Mexico, not an Iranian intercontinental ballistic missile test. The caption's 'Rastakhiz' ICBM details are unverified at best and contradicted by published reporting on the claimed weapon.

FAQ

Questions, answered.

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.
