A Strong Line Against Antisemitism
Online hate shouldn't go unanswered
Condemnation is not enough. It takes a response.
COUNTERLINE was founded to find antisemitic content, take it apart with facts, and mobilize an international community that actually responds.
Why now?
Online antisemitism keeps spreading — and the response still falls short.
On social media, partial information, hate and false claims can spread at tremendous speed and reach millions of people within hours.

The problem does not end when antisemitic content is posted.
It continues when that content stays online and goes unanswered.
COUNTERLINE works directly in these spaces: answering claims with facts, running campaigns and mobilizing an international community to act.
How we will work
Three steps — from detection to response
Identify
We will find antisemitic content, false claims and hate campaigns against Jews on social media and in the public sphere.
Verify
We will check claims against reliable sources. Information without sufficient support will not be published as fact.
Respond
We will answer claims with facts and reliable sources, in Hebrew and English, directly where the content was posted.
