See the signals behind every source.
SourceLens evaluates information quality in real time — credibility, citations, evidence, depth, and bias. It never tells you what to think. It shows you what to notice.
Privacy-first. Analysis runs locally — your browsing is never sold or tracked.

Every page is read through five layers of signal:
Core philosophy
Indicators and context — not verdicts.
SourceLens is not a fact-checker, a news rating platform, or a plagiarism detector. It will never claim something is simply “true” or “false.” Instead it surfaces the structural signals of quality so you stay in control of the judgment.

“This is true.”
Absolute judgments shut down critical thinking and erode trust.
It says instead
“This shows strong evidence.”
Signals and context that empower you to decide for yourself.
