Your Digital Detective Kit
A guide to the essential tools for fighting deepfakes, bias, and misinformation
The modern news landscape involves trying to navigate an information battlefield shaped by AI-generated content, hyper-partisan framing, and viral rumors designed to travel faster than corrections. Digital and media literacy is no longer a niche skill for journalists or academics; it’s a skill necessary for anyone online.
I’ve regularly shared resources on how to fact-check on here, but in this post I’d like to focus specifically on tools you can use to verify what you see, hear, and read. You don’t need all of them every day. You just need to know they exist, and when to reach for the right one. With fact-checking resources and organizations constantly being gutted, it makes knowing how to verify things yourself more important than ever.
Before I dive into specific tools, I want to shout out two extremely useful websites that regularly important resources in online verification. The first is Bellingcat, which is run by a collective of investigators and researchers that both debunk viral claims, but also provide free open-source tools as well (such as their AutoArchiver, which preserves and documents online before they are changed or removed).
The other website I’d like to highlight is Indicator. Indicator is a newsletter run by a long-time professional fact-checker and reporter on online manipulation. Not only do they have their own reporting and debunking, but they share open-sources tools as well, including their new Navigator tool, that will help you find the specific resources needed to verify something in question. I highly recommend both of these websites! Now let’s dive into some specific resources:
Checking Images and Videos
Google Lens / Reverse Image Search — Google's main tool for searching by image, and a great starting point for verification. When you right-click an image in your browser or upload one at images.google.com, Google runs it through Lens, which gradually replaced the old Reverse Image Search interface starting in 2025. The results are similar: you can find where an image has appeared online, check if a "breaking news" photo is actually old, or identify locations and landmarks. Just know this is a search engine, not a forensic tool so it can't detect manipulation. And be skeptical of any AI-generated captions that appear alongside results!
TinEye — If you want to find the oldest version of an image online, TinEye is your tool. It searches tens of billions of indexed images and excels at tracking down the original source of a photo that’s suddenly going viral. Free to use, though it only finds exact or near-exact matches so it won’t match different photos of the same person.
InVID WeVerify — If you want to go a step further, this free browser extension (Chrome and Firefox) calls itself a Swiss Army knife for verification. It can break videos into keyframes, run reverse image searches across multiple engines, and inspect image metadata. Some advanced features are restricted to registered journalists, but the core tools are available to anyone.
FotoForensics — Uses a technique called Error Level Analysis to highlight potential signs of digital editing. Worth trying as one data point, but with real limitations: it only works well on certain file formats like JPEGs, produces frequent false positives, and is largely ineffective against AI-generated images. The developer himself says it requires expert interpretation.
Lenso.AI — Disclosure: I was given a few free tokens to play around with this tool. Lenso.AI is a facial and object recognition tools can surface visually similar images even when they’ve been cropped, recolored, or lightly altered. Useful for deeper investigations that go beyond Google Lens, though the facial recognition feature is region-restricted, and full results sit behind a paywall (plans from $19.99/month).
Spotting Deepfakes and AI-Generated Content
No single tool catches everything here, but using a couple together (along with your own critical thinking) gives you a much better shot.
Hive Moderation — The free Hive Detect web tool and Chrome extension let you right-click images and text to check for AI generation. It scans for patterns from known models like Midjourney, DALL·E, and Stable Diffusion.
AI or Not — Even simpler: upload an image, audio file, or video and it tells you whether it’s likely AI-generated. Quick and easy, though free usage is limited and the self-reported accuracy may not reflect real-world performance. Again, exercise caution, and this is just one tool during your verification journey.
GPTZero — Maybe the most widely adopted AI text screening tool, but I'd exercise significant caution. It works by measuring how predictable and uniform your writing is, which means anyone who writes in a formal or academic style is more likely to be flagged, since AI models were trained on exactly that kind of prose. One study found it wrongly labels about one in ten human texts as AI-generated while missing over a third of actual AI content and non-native English speakers are disproportionately flagged. GPTZero itself says results should inform conversations, not serve as punitive evidence.
C2PA Content Credentials — Backed by Adobe, Microsoft, Google, BBC, and hundreds of others, Content Credentials attach cryptographically signed metadata to media. Think of it like a nutrition label showing who created something and whether AI was involved. Adobe’s free Content Authenticity web app and Chrome extension let anyone inspect Content Credentials. Not all platforms support it yet, but this is something to keep an eye on!
Fact-Checking Claims
When a claim sounds suspicious, these resources do the heavy lifting.
Google Fact Check Explorer — A search engine for fact checks. Go to toolbox.google.com/factcheck/explorer and search any claim to see if reputable organizations have already evaluated it. It aggregates over 150,000 fact checks. Google used to surface these in regular search results, but removed that feature in 2025, so you have to know to go looking.
Snopes — The internet’s longest-running rumor-debunking site. Great for viral hoaxes, urban legends, and those claims that sound just believable enough to share. Fact-checking sites should still always be verified, and it helps to cross-check their results.
PolitiFact — Best for political claims, using its Truth-O-Meter to rate accuracy with helpful context about why something is misleading, not just whether it’s false.
FactCheck.org — Nonpartisan and backed by the University of Pennsylvania, with a dedicated SciCheck feature for health and science claims. Especially useful right now given how much health misinformation circulates.
The Evidence Collective — Speaking of health misinformation, I want to highlight a new science communication nonprofit that I work with, The Evidence Collective (now on Substack). Our group of scientists and clinicians write up briefs that respond to timely health topics, in addition to sharing evidence-based health information in a variety of formats and spaces.
RumorGuard — Created by the News Literacy Project (also great!), this goes beyond labeling claims true or false. It teaches the Five Factors of Verification (Authenticity, Source, Evidence, Context, and Reasoning) using real viral claims as teaching cases. A great tool for building your own verification instincts.
AFP Fact Check / Reuters Fact Check — Especially useful for international or cross-border misinformation that U.S.-focused outlets might miss. AFP has roughly 150 fact-checkers across 26 languages.
Important note: Like AI-detection tools, fact-checking websites are imperfect. They work best when used together, over time, and alongside critical thinking, not as definitive labels for what is true or false.
Seeing Past Media Bias
Biased information can still have some truth. These tools help you see the full picture.
AllSides — Shows the same news story from left-, center-, and right-leaning outlets side by side. The comparison makes framing differences much more visible. Important to know: AllSides rates political lean, not factual accuracy. Like all of these media bias tools, they are a useful starting guide, not a perfect indicator.
Ground News — Highlights “Blindspots” which are stories covered heavily by one side of the political spectrum and barely by the other. The free version is useful for getting an overview of whether a story is covered more among right or left-wing media, but you get many more features starting at $8.33 a month.
NewsGuard — A browser extension that displays trust & reliability ratings for over 35,000 websites as you browse. Journalists review each site against nine criteria for credibility and transparency. Free on Microsoft Edge, $4.95/month elsewhere.
Ad Fontes Media Bias Chart — A visual map ranking outlets by both political leaning and factual reliability. Widely cited, and a helpful snapshot into our media ecosystem. Again, a useful starting point, not a definite conclusion.
Checking the Paper Trail
Wayback Machine — One of my favorite websites, and you can think of it like the internet’s memory. If a webpage was edited, scrubbed, or deleted, the Wayback Machine (web.archive.org) often has the original. It passed one trillion archived pages in 2025, though some major publishers now block its crawlers.
WHOIS Lookup — Want to know when a suspicious “news” site was actually created? WHOIS tools show domain age, registrar, and hosting info. Personal registrant data is now mostly redacted due to privacy regulations, but domain age alone can tell you a lot. For example, a site registered last week claiming to be an established news outlet is a red flag.
SunCalc — This is a unique tool that allows investigators to verify whether shadows in photos or videos match the sun’s position at a claimed time and location. Very cool & useful for deep dive verification projects!
Conclusion: Slow Down and Verify
The most powerful tool in your digital detective kit isn’t any kind of software. It’s understanding our own psychology and developing the habit of slowing down before you share. Critical ignoring helps us protect our attention, but when something does demand verification, I hope this list gives you a place to start.
Disinformation doesn’t just want you to believe a lie. It wants to exhaust you, confuse you, and make truth feel not worth chasing. These tools push back against that and provide you with more agency. You don’t need to catch everything. You just need to pause, check, and decide. The more of us who do that, the less of an impact misinformation and disinformation will have on all of us.
A really useful resource - thank you.
