See what's true. Before you believe it.
EvidenceLens checks videos, articles, podcasts and PDFs against millions of scientific studies — so you can tell facts from opinion.
Know more. Get manipulated less.
Four simple things, for every claim you come across.
Know what the research says
See which claims real studies actually support.
Protect yourself from manipulation
Spot confident claims that aren't backed by evidence.
Understand the context
Learn the limits and caveats behind each claim.
Check the sources
Read the research that the conclusions rest on.
Everyone has something to say. Who do you trust?
We have never had access to so much information. Yet it has never been harder to tell facts from opinion. EvidenceLens gives you a calm, evidence-based second opinion — in seconds.
Paste a link. We do the rest.
It really doesn't get simpler than this.
Paste a link
A video, article, podcast or PDF — anything you want to check.
We analyze it
EvidenceLens reads the content and finds the claims that matter.
You get clear conclusions
Each claim gets a plain-language verdict, with the sources behind it.
See what is actually known.
Every claim gets a clear, color-coded verdict — and you can open the studies behind it.
Supported by research
Backed by strong, consistent scientific evidence.
Treat with caution
Some support, but with important limits or mixed results.
Not confirmed
The evidence does not back this claim.
Not enough data
There isn't enough research to judge it yet.
Every verdict links to the publications it is based on.
This is how it looks
We don't tell you what to think.
We show you what's worth basing your decision on.
Built on real research, not just a confident guess.
Most AI tools answer from general training data. EvidenceLens is built around a library of over 200 million peer-reviewed publications, and matches the claims in your content to the studies that test them.
Generic AI
- Can sound confident without showing its sources.
- May miss the exact claim that was actually made.
- Splits summary, checking and follow-up across different tools.
EvidenceLens
- Starts from the actual content and the claims inside it.
- Checks each claim against a large library of research papers.
- Gives you verdicts, caveats, citations and chat in one place.
For everyone who wants to think for themselves.
And everyone who wants to make better decisions, every day.

Every check runs against indexed peer-reviewed publications — not blog posts or social media.

Frequently asked questions
The practical details before you install.
EvidenceLens is a fact-checking assistant. You give it a video, article, podcast or PDF, and it finds the key claims, checks them against scientific research, and shows a clear verdict for each one — with links to the studies. It works as a Chrome extension for YouTube and as a mobile app for everything else.
YouTube videos, online articles and news, podcasts, and PDF documents such as research papers or reports. Anything that makes factual or scientific claims is a good fit.
General-purpose AI tools can be useful, but they are not built specifically around YouTube transcripts and research verification. EvidenceLens is designed for the watching workflow: summary first, claim extraction next, then verdicts grounded in an indexed research database with citations and caveats.
Our database contains over 200 million indexed peer-reviewed publications sourced from established academic repositories and indexed on our own infrastructure. This includes papers across health, psychology, environment, education, economics, technology, engineering, and social science.

EvidenceLens extracts claims and matches them against peer-reviewed literature with semantic search. Each claim receives a nuanced verdict such as supported, refuted, overstated, or inconclusive, plus confidence levels and citations so you can review the evidence yourself.
