“CONFIRMED: 5G activates the virus when it rains!”
A false claim that resurfaces in the family group chat every few months, with no medical backing and no study behind it.
NEW 2.0 AI included · Web app and extension for Chrome, Edge & Firefox
Tired of endless fake news?
The school WhatsApp group. The video an aunt forwards. Whatever your kid is watching on their phone. Detector de Bulos checks what is on the screen as it happens and tells you, in plain language, what holds up, what is shaky and what is simply made up.
ANALYZING IN REAL TIME
Disinformation
“FORWARD THIS TO 10 PEOPLE BEFORE THEY DELETE IT: the government approves a 40% tax on the internet”
No source, no official record. Debunked by fact-checking organizations. Classic chain-message alarm pattern.

Ready to fight back against hoaxes?
Forwarded messages, clipped videos and invented headlines land at home every single day. Hoaxes race through the family chat in minutes, and by the time somebody debunks them the damage is already done.
“The government has been hiding the cure for cancer since 1972”
A conspiracy theory about suppressed treatments, forwarded to you as if it were a revelation, debunked by oncologists all over the world.
“A video proves it was all a lie”
Clipped videos, or videos with an AI voice-over, that your kids watch on a loop before anyone has checked a word of it.
The help you needed to check the news
You do not need to be a journalist or a tech expert. You just need to see, right there and with your kids next to you, where each claim comes from and how much confidence it deserves.
1. Detect
It pulls the specific claims out of the article, the forwarded message or the video you have in front of you.
2. Cross-check
Looks each claim up in verifications published by professional fact-checkers (Maldita, Newtral, EFE Verifica, AFP…) and in web sources, and only cites links it actually read: it never invents a source.
3. Explain
It shows the verdict, the confidence level and the links, so you can make up your own mind — and teach your kids to do the same.
Serious technology, explained in plain language
Pages, articles and forwarded messages
It pulls the main claims out of the article — or out of the message that just landed in your chat — and checks them on the spot. Included in the free plan too, AI and all.
Videos, reels and voice notes
It transcribes what is being said in a YouTube video, a reel or a live stream and checks it while you listen. Part of the Pro and Family plans.
A traffic light around the page
A colored frame around the page: green (verified), amber (questionable or incomplete), red (confirmed hoax) or gray (not enough data). A teenager gets it without reading a single line.
Try instant fact-checking
Paste the message that just landed in your chat, or pick one of the real cases, and watch the AI take each claim apart.
A real demo on the same engine as the extension (up to 5 checks a day per visitor). The example cases answer instantly.
On your phone, too
Hoaxes arrive on WhatsApp. Share them with Detector de Bulos and get the verdict, with sources, right on your phone. Nothing to install from any store.
Share and check
In WhatsApp, tap Share and pick Detector de Bulos: the verdict shows up on the same screen.
Screenshots read on your phone
Upload a screenshot and we read the text on your own phone. The image never leaves it.
Just like an app
Add it to your home screen and open it with one tap, on Android and iPhone.
Free, no sign-up. Checks run on the same engine as the extension.
Afraid your children are growing up surrounded by hate?
The /verificar/ web app works today on any phone or computer at home, and the extension is arriving on Chrome, Edge and Firefox: once it is published, your kids keep browsing as usual and see the warning when something does not hold up. Full parental control — PIN, a profile per child and reports for the adult — is coming very soon to the Family plan at no extra cost. It is parental control, yes — but mostly it is an excuse to talk at home about what they are seeing.
Real parental control
The install and the settings are protected by the parent or guardian profile. The child never touches the configuration.
Alerts on hateful content
Hate speech, harassment and disinformation are flagged the moment they appear on the screen — not a week later.
Weekly report
You get a summary of what was stopped and of the topics reaching them, without reading their conversations or logging their private browsing.
Install it on your parents’ computer and get the alert on your phone
Silent mode turns the extension into a remote shield: set it up once on the computer of whoever receives the most hoaxes and, when one shows up, the alert reaches YOU by Telegram or email. It does not read their messages or send you their history: it analyzes the pages that open and only alerts you about the ones that do not hold up. It arrives with the extension, as soon as it is published on Chrome, Edge and Firefox, and on every plan.
Install it in their browser
Two minutes on your parents’ or kids’ computer, or anyone you want to protect. They never have to touch anything else.
Turn on silent mode
No coloured frames or banners to bother them: the extension analyzes what reaches the screen in the background.
You get the alert
A Telegram bot or an email tells you the page and the verdict as it happens. You decide when to talk about it at home.

Frequently asked questions
Is Detector de Bulos an infallible truth detector?
No, and we do not want it to be. It is a decision aid: it shows you the verdict, the reasoning and the links so you can judge for yourself. AI models get things wrong and go out of date. Use it at home or in class as an excuse to ask "and who exactly is saying this?", not as an oracle handing down sentences.
Do I need to set up an API key or sign up with an AI provider?
No. The AI is included in all three plans: you check from the very first minute, no card and no technical settings (today on the /verificar/ web app; the extension is being published). If you want to, on any plan you can plug in your own API key (BYOK): it is an advanced option that keeps the content off our servers entirely; on Pro and Family it also gives you unlimited checks.
What about the privacy of my data and my children’s?
With the included AI, the text you analyze travels encrypted to our server in Madrid, where a model hosted on our own infrastructure analyzes it, and we hand the result back to you. We do not keep the full message, there are no ads, no third-party trackers, and that content is never used to profile you. If you would rather it did not pass through us at all, on any plan you can switch on your own key (BYOK) so the analysis goes straight from your browser to the provider you choose.
Can I use it in the classroom?
Yes, and it is one of the uses we care about most. In class it works as media-literacy material: you analyze a headline in front of the group, read the reasoning out loud and discuss whether the sources actually back the claim. The point is not for the AI to hand over the answer — it is for students to learn to ask for evidence first.
How does parental control work?
It is a feature coming very soon to the Family plan, at no extra cost for active licenses. The adult will switch it on from their own profile, locked behind a PIN, so the child will not be able to turn it off. The extension will flag disinformation and hate speech as it appears, and you will get a report of what was stopped: online child safety without reading their conversations or logging their private browsing.
Does this replace professional fact-checkers?
No, and claiming otherwise would be disrespectful to their work. Their standards are exactly the bar we measure ourselves against: when a fact-checking organization has already debunked something, the extension shows you their debunk and links to it. What we add is bringing that rigor to the moment the message reaches you — on your phone or in the classroom — when you do not have twenty minutes to go looking.
Which browsers can I use the extension in?
The /verificar/ web app works today in any browser. The extension is arriving on Google Chrome, Microsoft Edge and Mozilla Firefox on desktop. Audio and video checking (YouTube, reels, live streams) is available in Chrome and Edge, and is part of the Pro and Family plans.
