Show HN: Factifi – Real-Time Fact-Checking Content
Hi HN — we built Factifi, a Chrome extension that does instant fact-checking on anything you’re reading or watching. Please keep in mind, this is just an MVP and will be buggy and fail.
We were constantly pausing podcasts and Substack posts to ask, “Wait, is that actually true?”. After too many 30-minute Google rabbit holes, we decided to automate the work.
What it does
• Extracts claims from articles, blogs, YouTube videos (and even images)
• Assigns a verdict + confidence score using live web search, a 200 M-paper research index, and a few proprietary datasets
• Flags likely deepfakes and manipulated images
• Runs entirely in your browser — only the claim snippets leave your machine for scoring
Status
• Free during early access (no wait-list)
• Read more here (factifi.me/blog)
Looking for feedback on
• Accuracy thresholds (where should we draw “unverified” vs. “false”?)
• UX friction — what feels clunky?
• Ideas for new features
Happy to answer anything in the comments—thanks for taking a look!
- shrishti12 1y agoCan it fact check articles, posts etc?
- umittal 1y agoYes. Please install. You can see it!
- AddySmith2410 1y agoSounds interesting, can you tell me more about the claim generation?.
- umittal 1y agoWe use some peer reviewed methods to identify questionable claims.
- ka2429 1y agoFerrari is losing coz of its strategy. Please fact check it
- umittal 1y agoSorry. They’re just ass.
- Klonoar 1y agoCan you expand more on what "proprietary datasets" means...? Where are the research papers pulled from? Edit: it's also immediately obvious the number of brand new accounts that are engaging in the comments here with generic comments.
- umittal10 1y agoOkay, firstly you we use SEC and a few other datasets from Google and similar datasets. We filter them based on credibility. The research papers are pulled from a corpus called Semantic Scholar which is pretty high quality. We also do ArXiv and PubMed.
- slater 1y agoCan it also check "Show HN" posts with suspicious amounts of simple replies made by suspiciously-new user accounts?
- umittal10 1y agolol we’re trying to prove that the internet is biased.
- wredcoll 1y agoBiased towards what is the far more important question
- umittal10 1y agoBiased towards whatever the hell someone wants to portray. Truth is no longer displayed, what’s displayed is only what you want. HN is one of the better platforms and so you can tell. What about the others where bots dominate?
- slater 1y agoAstro-turfing your own Show HN post is not the way to go about it.
- defrost 1y agoWhat does it conclude about the full and complete comment histories of these three accounts? * https://news.ycombinator.com/threads?id=ka2429 https://news.ycombinator.com/threads?id=ka2429 * https://news.ycombinator.com/threads?id=shrishti12 https://news.ycombinator.com/threads?id=shrishti12 * https://news.ycombinator.com/threads?id=AddySmith2410 https://news.ycombinator.com/threads?id=AddySmith2410 Is there are word to describe that behaviour?
- umittal10 1y agoThanks for proving our point for us. People will do whatever they want. Some of us are smart enough to check the truth, but most of us are not. There’s a need for fact checking and hopefully, people can come to a consensus on that.
- aan85 1y agoHow long does it take for a claim to be verified?
- ab2345 1y agoCan it be integrated with social media platforms? Since that is where most misinformation is circulated
- yerbamatte911 1y agoThis is cool! Unique idea
- mattwashere 1y agoHow is your model able to identify deepfaked images??
- deleted 1y ago[deleted]
- MansNotHot 1y ago[dead]
- vstar2000 1y agoCan users see why a claim was marked true/false — like a list of top supporting sources?
