Google is developing a free moderation tool that smaller websites can use to identify and remove terrorist material, as new legislation in the UK and the EU compels Internet companies to do more to tackle illegal content.

The software is being developed in partnership with the search giant’s research and development unit Jigsaw and Tech Against Terrorism, a UN-backed initiative that helps tech companies police online terrorism.

“There are a lot of websites that just don’t have any people to do the enforcement. It is a really labor-intensive thing to even build the algorithms [and] then you need all those human reviewers,” said Yasmin Green, chief executive of Jigsaw.
